St. Patricks Day Cake

filed under: Miscellaneous on March 11, 2011

The smiley, happy, silly rainbows on this cake are totally inspired by those amazing frosting covered sugar cookies you get at the bakery. Or at least, at the grocery store bakery that I would frequent in my youth.

Those cookies were the only thing that made shopping trips tolerable for my mother when I was young. The promise of just one of those delectable cookies was enough to exhilarate my senses and make me… well… behave.

Its funny how sugar still triggers that emotional response in me today!

Anywho… here are some over the top, crazy, supposed to make your heart happy rainbows.


All of those rainbows are pure sugar highs… courtesy of my favorite buttercream recipe of all time.


Since this is a St. Patrick's Day cake I actually made hundreds of gold coins for the base of the rainbows. I just made my homemade sprinkles, only bigger. But since I made them bigger they were taking forever to dry and I got impatient.

Hence, fluffy frosting clouds.

Next year I will plan better.

I mean, I probably wont, but I can pretend.


And then, because it seems to be physically impossible for me to make a cake without a surprise inside, I decided to add a shamrock.

Seriously… I made so many impulsive choices on this cake! I dont know what I was thinking.

Like instead of a bright green jolly shamrock, mine is really, really dark. I thought it would be a fun to make Nigella's Guiness chocolate cake (beer… St. Patrick's Day… it seemed like a good idea) and then just add a little bit of green so it wouldn't be IN YOUR FACE green.

Like with this St. Patty's Day cake.

I will show you what I mean.


Its dark.

And mostly resembles a shamrock.

At least it tastes fantastic!! (white cake recipe here)

This was one TOUGH cake. I really dont think a tutorial is possible because I need a full year to forget how much work it was.

Sorta like having a baby. Which I will be doing in 17 days. (scheduled C-Section)

TMI for a baking blog???

Sorry. ๐Ÿ™‚

    Holy cow!! I cannot believe this cake. I am just stunned at the shamrock, which totally looks like a shamrock by the way! And all this at this far along in your pregnancy? Are you joking me? I would so be on the couch eating girl scout cookies. Who am I kidding, I totally am doing that and I’m not even pregnant. Ha!

    I die. I DIE! This CAKE is beyond my DREAMS!!!!!
    True story: when I was a little kid I wanted a cake with a rainbow on it REALLLLY badly. The cake I was served had a “rainbow” with random colors that were out of order. I was Very disappointed. THIS was the Cake of my Childhood dreams!!! Realized like, 24 years later!
    You are so incredibly talented and your blog entries are such a gift!

    17 days? that happened fast…hihihi…. apologies :O)… at least from my side of the screen.

  • Brenda @ a farmgirl's dabbles says:

    I love, love, love the rainbows and clouds on this cake. It reminds me of the 3/4-length baseball shirt I had as a kid, with a glittery rainbow iron-on, and the letters of my name ironed on down my sleeve. ๐Ÿ™‚ And I’m not going to even ask HOW IN THE WORLD you made that shamrock. Now THAT would be TMI!!!!!

  • Gabrielle says:

    Miam miam!

  • Lori @ RecipeGirl says:

    You’re so freakin’ amazing. I heart you.

  • Avi Cataudella says:

    I was actually going to attempt something like this, since when I made your heart cake for valentines day, it was a huge hit and the bf’s work! Although, with two days to go, might skip it this year and just make them a reg cake with an ices St Patty’s day theme. There’s always Easter!
    Thanks for the always inspiring posts ๐Ÿ™‚ You’re an amazing baker, and good luck with the C-section!
