Leprechaun Trap Cake

leprechaun trap rainbow cake

This may look like a perfectly innocent cake meant to lure a leprechaun to the top but it has a few secrets.

leprechaun trap rainbow cake

Secret #1: Beneath the pile of gold coins are fragile bars, when the leprechaun approaches to grab the coins he’ll fall into the pit and be trapped.

Secret #2: There is a rainbow hiding inside the cake. The leprechaun will discover this as he eats his way to freedom.

Have you heard of Leprechaun traps? I hadn’t encountered these until this year, and I am completely charmed by them. Leprechaun traps are created by kids in order to lure and trap a leprechaun. They are often a craft or sort of science experiment, there are some amazing ones collected here at Geek Dad. You can see plans for some at Family Fun (including the one that inspired my cake), and a round up at How Does She.

I decided that my angel food cake pan, with the hole in the middles, would make an excellent shape for a leprechaun trap. As bored kids growing up in suburbs we used to make traps similar to this for each other by digging a hole in the ground then covering it with a few fragile branches, a layer of leaves and finally topped with some loose grass to hide it. I’m shocked nobody ever broke an ankle.

To read the complete how-to for this cake please click on MORE.

leprechaun trap rainbow cake

To form the rainbow in this cake I used the method shown here at Omnomicon which is very simple — separate your cake batter, color each section, then pour it into your cake pan one color on top of the next. The first time I saw this method was when my friend Maggi (hi Maggi!) made one a few years back. (update: Maggi’s cake is over here. Pretty.)

The trouble: Usually when one makes a cake like this you divide the batter into equal parts but that results in the color that went in first spreading out more as it cups around the colors that come on top. The result is that when you cut a slice of the final cake you get less of some colors and more of others.

leprechaun trap rainbow cake

You can see this effect in the image above from Omnomicon, the color poured in last is much more prominent than the color that went first, which is squeezed and spread around the bottom.

I really hoped to create a more traditional rainbow arch and distribute the colors so they would result in more even appearance so I decided to change the ratio of the colors of batter. The color poured first (in this case red) was given more batter than the color poured second (orange) and so on, the last color (purple) got the least amount of batter. I think it turned out fairly well. (But I see some room for improvement in the future.)

leprechaun trap rainbow cake

So this is what I did. I used one box of white cake mix and separated the batter into eight bowls:

  • 6 ounces – red
  • 5 ounces – orange
  • 4 ounces – yellow
  • 3 ounces – green
  • 2 ounces – blue
  • 1 ounce – purple
  • 1 ounce – to be kept white
  • the rest of the batter, also kept white

I used an angel food cake pan, but if you have a more rounded bundt pan I think it would work out even better as it would look more like a hill. update: I’m doing some tests in different pan shapes and finding that rounded pans and taller pans (or more cake batter put in an angle food cake pan) doesn’t create the same arch shape. I’m doing all sorts of test (yay for reasons to buy more cake pans) and I’ll report back when I find out more.

leprechaun trap rainbow cake

To make pouring the batter easier I filled plastic bags with each color then snipped the corner just before I needed it. I think this gave me a bit more control than scraping it from a bowl, but be aware that it’s difficult to stop the batter once it’s started so get a good hold on the bag before you start — one hand should be on top to squeeze the batter.

This makes for pretty dishes.

leprechaun trap rainbow cake

First pour the larger amount of white batter into the pan. Then pour the red batter in, making it a wide ring of batter. Then pour the orange over that, keeping it inside the red. I found it was easier to control the ribbon of batter holding the bag a bit higher over the pan and trying to be zen about it.

Pour in each color, creating narrower and narrower rings. As you go along snip smaller corners off the bags, it will help you control the narrower shape you are trying to make.

Last pour the remaining ounce of white batter on top. I had hoped this would make the rainbow dome have a more hollow center but mine didn’t quite turn out, so you might not even bother with this last one unless you’re feeling ambitious.

Put the cake in the oven, you might consider baking it at 325 instead of the usual 350 as it will dome a bit less when baked at a lower temperature. I forgot to do this.

While the cake is baking you can create your pretzel ladder. I used milk chocolate candy melts as glue, dabbing it in place using a toothpick then setting the smaller pretzels on top. I held the pretzel rods in place by supporting them with quarters. You might want to remember to wash your quarters first if you anticipate anybody eating the ladder. Ooops.

Here is the ladder in better light. (I bake at night, it doesn’t make for great photos. My deep apologizes for the assault on your eyeballs.)

leprechaun trap rainbow cake

Level off what will be the bottom of your cake, this will also help shape the base of the rainbow arch as the batter will curve under itself creating more of a rainbow horseshoe.

Flip it right side up onto your cake plate, then slide a few rectangles of parchment paper under the edges so you can be messy while frosting the cake. When you are ready to present it you simply pull the parchment paper away and, ta da, an effortlessly clean cake plate. I learned this on the old Martha Stewart show. I miss that show.

To frost the cake I made a half batch of the Magnolia Bakery buttercream frosting recipe found at First I did a crumb layer, followed by a few minutes in the freezer. (It’s amazing I can make room in my freezer for something like this.)

leprechaun trap rainbow cake

I used at Ateco 234 tip, it’s one of the larger ones. Probably not the best for creating something like grass but I already owned it so I went with it.

I sunk some pretzel sticks over the middle hole in the cake to create a sneaky platform for our gold.

Then I simply piled foil wrapped gold coins over the pretzel bars.

I created a sign using the international image for “Hey, the end of the rainbow and the pot of gold are over here!”.

And stuck the sign into the cake using a popsicle stick.

Discoveries made:

  • You will stain your lips green while eating this.
  • My cake plate tilts to one side.
  • And I completely forgot to add the vanilla to the frosting.


  • Bake at a slightly lower temperature, say 325, to avoid doming.
  • If you use cake batter from scratch here is how I decided how much batter to separate out for colors — I took 2/3rds of the batter for color and divided that in amounts of 6/5/4/3/2/1 parts. In my cake the total batter was 34 ounces. Two-thirds of that is 22 ounces. Happily 6 + 5 + 4 + 3 + 2 + 1 = 21 ounces, which was close enough. YMMV (your math may vary).

Notes on different cake pan shapes:

  • I baked rainbow cakes in a bunch of different shapes of cake pans and took photos of the results. Turns out? The rainbow arch effect works best in the angel food cake pan. Otherwise the colors swirl a bit more, still very pretty but more tie dye than rainbow.

    Even if I’m not trapping a leprechaun, I think this is an excellent use for a bundt cake pan! Can’t wait for the how-to!

  • 12 Mara // Mar 16, 2011 at 3:25 pm

    Great idea! I had forgotten all about leprechaun traps! As a kid I used to make them out of twigs and acorns in the woods!

  • 18 Lisa // Mar 16, 2011 at 4:41 pm

    Wonderful! I need to remember this for next year. My sons’ trap for tonight is a big basket with chocolate chips. The theory: according to a 4 and 6 y/o, the leprechaun will eat all the chocolate chips and will be too sick to move.

    best idea ever!

  • 29 Rachelino // Mar 16, 2011 at 9:22 pm

    That is so clever, and would put anyone in a good mood, even a hardened old anti-food coloring hag like me. I love it. Amazing job.
    All the color reminds me of this rainbow cake (all are individual layers in this one though) that Gesine made.

  • 30 Jennifer // Mar 16, 2011 at 9:51 pm

    What a clever idea! My kids would love to help me make one of these. Thanks for the inspiration!

  • 39 Sarah (mrsgryphon) // Mar 16, 2011 at 11:43 pm

    I adore this cake, and my rainbow-loving daughter would be so excited! Somehow, I don’t remember ever hearing about leprechaun traps until my daughter made one at school today – now this, and more on Twitter etc. So fun!

  • 40 Kathleen Coleman // Mar 17, 2011 at 1:15 am

    I love this and I’ve never seen it done before! I’m hungry just looking at it and feel a sugar coma coming on! Thanks for sharing!

  • 41 tydell // Mar 17, 2011 at 2:16 am

    this is the thing you should put in art gallery. it is to painful to eat after all that effort.

  • 42 Sarah // Mar 17, 2011 at 2:27 am

    This is awesome! I’ve actually never heard of leprechaun traps either? I wish I had time to make one for St. Patty’s day.

  • 43 Sheena B // Mar 17, 2011 at 3:32 am

    This is just too cool. I can so see using this for a child’s birthday party as well. Showed it to my other half and he thought it was beyond amazing.

  • 44 Korie B. // Mar 17, 2011 at 4:22 am

    I absolutely love this! Thanks for the “how to”.

  • 48 Erin in PA // Mar 17, 2011 at 5:41 am

    So. Awesome. I am definitely going to make this with my little lassie tonight! Those tricky leprechauns have already moved our chairs around and made the toilet water green at our house (oh what fun it is to have a 4 year old!)

  • 49 Nichole // Mar 17, 2011 at 6:10 am

    So cool! I wonder if I can make that happen today.

  • 50 Steffy // Mar 17, 2011 at 6:34 am

    While I could never see myself making something so complicated, you did teach me one thing. The parchment paper! Genius.

    And, I’m totally impressed.

  • 51 Raquel // Mar 17, 2011 at 6:47 am

    My son is already grown up, but I still want to make this. Wow! Beautiful!

    Gorgeous photos.
    Wonderful text.
    You clearly went to a lot of work writing and photographing this post, and it’s not lost on me.

    Thank you for taking the time to share all the details…including the ones at the end about what you “would and wouldn’t do” next time.

    This is one of the most inspiring blog posts I have read in ages! In fact, I am on my way to my favorite cake decorating supply store in a few minutes, thanks to you!

    (I feel the same was as “Rene”. I “rarely gush” as well, but this….this is very gush-worthy!)

  • 72 Fitzi // Mar 17, 2011 at 10:38 am

    I love this idea. I am this close to taking the afternoon off of work so that I can make this cake. I feel that because I’m Irish, I can justify taking the afternoon off to bake and drink Guinness, right? Anyway, thanks for the awesome inspiration. I linked to this page from my blog, hope you don’t mind.

  • 73 Kathy // Mar 17, 2011 at 10:50 am

    Brilliant! You amaze me!!

  • 74 kelly // Mar 17, 2011 at 11:11 am

    holey moley – this is fantastic. I loved reading how you did it, too.

  • 75 Joanna // Mar 17, 2011 at 11:25 am

    That is AWESOME!

  • 76 Yewtree // Mar 17, 2011 at 12:02 pm

    Fabulous cake, and very clever how you did the marbling.

    What happens to the leprechaun after it’s been trapped, that’s what I want to know? Does the cake-maker demand three wishes and then let it go?

  • 77 Barbara | VinoLuciStyle // Mar 17, 2011 at 12:10 pm

    Love this…although must admit my cake this year has some coffee and a bit of Irish Whiskey…big girl cake. I need a little one to make this for, I would love to experiment with the rainbow of colors.

  • 78 Tiffany // Mar 17, 2011 at 12:20 pm

    This is really cool! I want to make this for my daughter’s tea party. The girls will love the rainbow.

    I love this and I am going to make it next St Pat’s day (if I remember before 10PM on the 16th!) My kids will LOVE it too. Thanks for sharing the info on how to make the rainbow, your instructions sound a lot easier than I would have guessed.

  • 82 foodiesonthefly // Mar 17, 2011 at 1:56 pm

    Most adorable cake. Love all your photos, very expressive.

  • 83 Rosie @ Sweetapolita // Mar 17, 2011 at 1:57 pm

    YAY! Thank you for the “how to” yay! :)

  • 85 Meridith // Mar 17, 2011 at 3:27 pm

    You made it look so easy with all the great photos. I especially love the photo of the empty bowls and spoons!

  • 86 Reading (and chickens) // Mar 17, 2011 at 7:04 pm

    OK, what kind of food coloring did you use? Our colors were nowhere near as bright as yours! (Also nothing else looked like yours, but that’s not really due to poor quality food coloring, just poor quality craftiness.)

  • 87 megan // Mar 17, 2011 at 7:19 pm

    Reading (and chickens) – I used both AmeriColor and Spectrum gel paste food colorings found in cake decorating stores and in the Wilton area of craft stores. The gel colors are very vibrant. For each color I mixed a few — Super Red and Maroon to get a rich red, Leaf Green and Electric Green to get a nice grass green that wasn’t too kelly, that sort of thing. I just realized I didn’t mention the sort of food coloring I used in the post, my bad! You can see the tops of the gel containers in the photo with the ring of bowls filled with colorful batter.

    I’ve checked out your cake and I love it! The rounded bundt looks so much more like the hill I was imagining. I love the signs your sons made!

  • 88 Betty // Mar 17, 2011 at 7:38 pm

    AS USUAL… amazing stuff. LOVE the idea. So much.

  • 89 Rebecca // Mar 17, 2011 at 7:44 pm

    You are the best kind of crazy.

  • 90 Reading (and chickens) // Mar 17, 2011 at 7:50 pm

    Thanks Megan! They were pretty proud of their signs, but they did ask why it didn’t look like yours. I said we had to practice and eat lots of cake (they are ok with this plan, shockingly). I’ll look for AmeriColor and Spectrum for next time.

  • 91 Melissa // Mar 17, 2011 at 8:30 pm

    I love it! We are totally making one of these next year.

  • 92 Christine // Mar 17, 2011 at 9:14 pm

    I made it today, turned out a little different in the rainbow form but was short on time. My younger daughter and I just decorated it with green buttercream and put on gold coins. My older daugther was amazed when we cut into it tonight and saw the rainbow, everyone thought it was amazing! Thank you for the great idea!

    I am soooooo blest with your wonderful instructions and beautiful photos … they are so helpful and following them will be such a help to me.

    I am a 77 y.o grammy who is really enjoying my retirement. First with my awesome quiet times with the Lord and now with new learning experiences from people like you. May God bless you abundantly as he is me with the likes of you.

  • 99 Anne-Marie Faiola // Mar 18, 2011 at 11:40 am

    WOW. This cake is amazing! I love rainbow cakes because they’re so fun and colorful but you really took that to the next level. Great job =)

  • 100 Holly // Mar 18, 2011 at 11:57 am

    Amazing! We made our first trap this year (the Family Fun version) and my son already has said he wants to make one every year. This might be a job for my food-editor husband, however!

  • 101 Carrie // Mar 18, 2011 at 12:06 pm

    Ohhh I am making this tonight with my kiddos! This is too cool :))

  • 102 Meri // Mar 18, 2011 at 12:44 pm

    Holy cow, I’m not worthy of this cake! I got a headache just trying to figure out how to make the rainbow! Well done, this is the cutest thing. It reminds me of when on “how it’s made” or “unwrapped,” they showed the “mystery” of ribbon candy, and how they get the picture inside. Mind boggling to me, but impressive :)

  • 103 gina // Mar 18, 2011 at 12:54 pm

    I LOVE this cake. We have made rainbow cupcakes and those go over really well. But, I even thought this would make a great pick-me-up cake for someone who might need to “see a rainbow”.

    Love it! Thanks for figuring this whole process out. I never would have figured all that out. LOL.

    My birthday is St. Patrick’s Day, and my youngest sister made me this cake! It was amazing. My only wish is that I had skipped this blog for a few days so that the rainbow would have been a complete surprise for me. She used a rounded bundt pan and skipped the white inner and outer layers, and it came out looking perfectly gorgeous. I love all the rainbow cakes I’ve seen, but I think your style is the best yet.

    Hello, very cute idea and looks great you can help reduce the batter spreading by freezing cake after every addition of the colored batter and then freeze for a bit then put in oven. You will have less spread and see more complete rainbow.

    Help. I’ve made it twice and my sister once. We can’t seem to get the rainbow shape. One time the blue dropped all the way through the center and ended up next to the red. I made it with a mix with pudding and we’ve made it with “regular” mix. The pudding mix was rather thick and perhaps the regular mix was too runny. We used a rounded bundt pan. Any suggestions?

    This came out ok in a pound cake pan (what I had on hand): not a perfect rainbow, but close. Angel food pan with the straight sides is still a better choice. I had a bit of leftover batter, and made a few cupcakes, red on the bottom, smaller circles of remaining rainbow colours, with a dab of purple in the center. They resulted in a rainbow starburst pattern, and were a huge hit. Thanks so much for sharing–

    I tried making this cake, and alas, the rainbow turned out to look more like a fruity pebbles cake. I did realize that I had nowhere near the patience you had with frosting, so instead I dyed shredded coconut green and put it on the outside of my cake after the crumb coat. It worked surprisingly well and gave a good grass feel, though it lacked the cute cartoon feel.

  • 129 Nancy // Apr 4, 2011 at 8:13 pm

    The cake is of course fantastic, but what attracted me to the story was the leprechaun trap. For years after my son’s first grade teacher told them about Leprechaun traps, he and his younger brother would remember to set them on March 16th. Some years were more elaborate that others, and since my husband and I met (several years prior) on St. Patricks day, it was well celebrated here in this household. My now 15 year old younger son was even quite impressed with your cake ( a real sweet fiend), and got a chuckle from the trap idea! Thanks for the memories.

    I was so excited about this cake that I made it with my sister. We followed the instructions to the T (except for the food coloring; we used standard gels from the grocery store) and we ended up with a tie-dyed cake. Any suggestions? I didn’t think that slight differences in the amount of food coloring added to the different colors was enough that the density change would cause certain colors to sink, but it’s the only explanation I can come up with.

  • 134 megan // Apr 11, 2011 at 9:53 am

    Stephanie – Did you use an angel food cake pan? I just posted my results of baking this cake in different shapes of cake pan. So far it seems that making a shallow cake in a flat bottomed pan with straight sides works out best. I got some crazy results.

  • 166 Denise // Jun 23, 2011 at 8:38 pm

    I am using a boxed cake mix. I did divide it into the 6 colors, and ranging from 1 oz – 6 oz. This left me very little of the non-colored cake mix. It was only about 1/3 inch deep in the pan. I worried that there would be no room at all for it to arch so I mixed up another cake and added just about another cup and a half to the base; then added the colors like you said. The box never says how long to cook the cake when you’re using an angel food cake pan (of course.) And both the box and you suggested 325….still with no suggestions of how long to cook it. We’ll see how it turns out. I am just using the “bundt pan” time on the box. Not optimistic, unfortunately. I used this to do an actual angel food cake last week. The mix is so light and fluffy that I don’t think it was heavy enough for all the colors to “fall” into the arch while baking. It was pretty, of course, but not a rainbow….anyway, fingers crossed. Hey, we have colored cupcakes in case the cake is a flop. THANK YOU for the idea. You did great!!

  • 175 Sarah // Jan 14, 2012 at 6:57 pm

    Just chiming in with my results, since I’ve made this cake three times now and the rainbow has worked reliably each time. I use one box of Betty Crocker white cake mix (be sure to mix it the full two minutes on medium to get it really beaten and fluffy), Wilton gel colors to get the tints, and bake it in an angel cake pan that’s been lightly sprayed with Pam. About 45 minutes at 325 (I use the good old toothpick test to make sure it’s done) and then I cool it on a rack with the pan side removed but the cake still sitting on the tube/base. It’s quite fragile and soft, and I’ve had one break into pieces when I tried to take it off while still warm.
    It’s turned out to be the best baby shower cake ever! Megan, thanks for making me look good. ;)

    Hey I was thinking about doing this as a treat for a class, how do you think cupcakes would work?

  • 180 megan // Feb 3, 2012 at 10:21 am

    Kelsey – The batter won’t swirl quite the same way while cooking but it still turns out very nicely. Go see this Google search for rainbow cupcakes and the first five results are all good links, there is also a Youtube video. For cupcakes the batter is divided evenly since the swirl effect while baking doesn’t take place as dramatically. Also, you might consider baking these at a slightly lower temperature, the cupcakes won’t dome as much.

    The only thing I’m confused about with this cake is that in the picture, there were two of every color (adding the dyes, you made a double rainbow), but when you cut into the cake, it was only one rainbow. Also, I don’t have any pretzel sticks. Short of using REAL sticks or melting chocolate then molding and freezing, do you have any suggestions for substitutes?

    Thank you for sharing! My daughter (7) and I made this in hopes of trapping a Leprechaun. The instructions were great, and the cake turned out great too. Unfortunately the trap wasn’t 100% effective, the little guy left footprints in the frosting and fell through the gate, but was no where to be found. My daughter said he must have used the rainbow to escape, and with the loot! Even with an escape, we might try this trap again next year :)

    Love this cake, I made it for St. Pats day Dinner and it was a HIT!! Now I’m wondering, would it be possible to do this in reverse, or go small to big to small again, to create an easter egg inside?? Probably not, because of the way it rises….but I’m curious and might give it a shot.

  • 210 megan // Mar 31, 2012 at 1:03 pm

    Carrie – I’m afraid the best I can do is swirly patterns with this technique, but check out I Am Baker for surprise-inside cake tutorials. The one I linked to there could easily be turned into an easter egg shape!

  • 227 Cheryl Hyter // Feb 25, 2013 at 2:53 pm

    Dear “Not Martha”, I am SO impressed with your cake!!! I want to make it for sure. I can give you a suggestion I learned in Wilton class about baking temp. I’ve done this for about 20 years and it works every time. Bake for 1 hour. Start at 250, after 15 minutes raise to 275, after 15 more minutes raise to 300, and for the last 15 bake at 325. The cake is always supermoist, and raises slowly so the middle doesn’t make a hump. Blessings!

  • 228 Jen // Feb 27, 2013 at 4:42 pm

    So, I am definitely going to try this cake this year, but I have one silly question – are your ounce measurements liquid or weight ounces? I’m hoping weight because using my scale seems a lot easier than mucking around with measuring cups!

  • 229 bakingismyzen // Feb 27, 2013 at 7:19 pm

    too cute for words…


  • 230 megan // Feb 28, 2013 at 9:51 am

    Jen – All the weights of the amounts of cake batter that I used are above, in ounces. I used my scale for this as well.

    I love this! Ingenious! I made a 6 layer rainbow cake for my daughter’s Rainbow Party which was awesome but this looks so cool with the arch and it requires less spreading of frosting. Thank you for sharing!

  • 233 Carrie // Mar 5, 2013 at 12:14 pm

    So cute! Cannot wait to try this. Thanks for sharing your beautiful cake!

  • 234 Amber // Mar 9, 2013 at 6:12 pm

    What is the cookie that is in the middle of the cake under the pretzel sticks? It’s driving me crazy that no one has it listed on any of the pins. Super excited to make this with the kids this week for spring break!

  • 235 megan // Mar 10, 2013 at 4:06 pm

    Amber – What you’re seeing isn’t a cookie, it’s a reflection from the steel cake plate below the cake. The small circle in the very center is where the base is attached to the top. Looking at the photo I can absolutely see what you are perceiving as a roundish cookie though, like a fudge stripe cookie sans the stripes or something. Sorry you were confused, and thanks for taking the time to come over and ask!

  • 236 Roberta West // Mar 12, 2013 at 2:48 pm

  • 238 Jessica // Mar 15, 2013 at 8:17 am

    This cake is too adorable! I’m making it tomorrow with my 3 year old son who is going to love this!! 1 creative idea I had for this is…..if I could find a small leprechaun figurine/toy it would be awesome to sneak him into the center of the cake after its baked & before you decorate it so that when you cut into it, to your child’s surprise is the leprechaun you caught!! Thanks for the awesome tutorial!! Can’t wait to make this :-)

    I made this! The instructions here were easy to follow and even I was surprised when we cut the cake and there was actually a rainbow inside. I never would have thought I could do it. I also printed a small leprechaun and put him at the bottom of the hole under the cake so it looked like we caught him in the trap.

    April – Yes, I used one box of cake mix. I made this in an angel food cake pan and after rising it was still only about half the height of the pan. Have fun!

  • 272 Mary // Mar 16, 2015 at 6:53 am

    Do you flip the cake before frosting? I’ve made this before and my rainbow was upside down. I can’t remember which way it should go…

  • 273 megan // Mar 16, 2015 at 10:28 am

    mary – The cake as shown is upside down to how it was in the pan. Or: as it bakes the top of the rainbow arch will be pointing to the bottom of the pan.

    I flipped it out of the pan, turned it over to trim the doming (on what will become the bottom of the cake), and then flipped it over again.

    Does that help? I hope it does!

  • 274 Marianne Allan // Oct 9, 2015 at 2:20 am

    In lieu of pretzel sticks why not use chocolate sticks – you can get ones with peppermint inside.
