f you have a thing about food coloring, look away. Do not go any further because were about to enter the land of color.

Lots of color.

6 Layer Rainbow Cake

I had fun with this cake.

The last time I made a Rainbow Cake, it was for my daughter’s 8th grade graduation almost 2 years ago. It was time to make it again, this time for St. Patrick’s Day. I used the wedding cake recipe that I used last time but I used the whole recipe (last time I cut it in half) which gave me one. big. cake. It starts with a couple of white cake mixes but you add flour, sugar, egg whites,  sour cream and the likes. Mine is  flavored with almond and vanilla extract but it’s easy to switch up the flavor to what ever your heart desires.It produces a nice sturdy cake that stacks nicely. And with 6 layers, it had to stack nicely!

rainbow cake layers

I used about 2 cups of batter for each layer this time but the last two layers got a little bit short changed. They only got about 1 1/2 cups batter because I didn’t measure real good. But once I trimmed up the other layers, and stacked them up, you really couldn’t tell the  difference. In fact, I thought it was funny when someone asked me how I got my layers so even. Ha! If they only knew!

I piped a layer of frosting around each layer and filled it with a candy bar filling.

This is a fantastic filling. It’s basically a pastry cream and you can change it out with your favorite candy bar.

Toblerone filling

I wanted a white filling, so I went with Toblerone White Chocolate with Honey and Almond Nougat.

What a great choice that turned out to be.

That stuff was KILLER!

Surprise rainbow cake

I wanted the bright layers to be a surprise, so I frosted it with a simple white frosting. I got the recommendation to use Martha Stewart’s Fluffy Vanilla Frosting recipe from Patsy. She made some cupcakes with the frosting and said it was a hit with her kids. In fact, they said it tasted like ice cream.

Enough said,  I had my frosting recipe.

It was a delicious butter cream and so easy to whip up. But I had to slap on the frosting pretty quickly before work  so I didn’t get a chance to do crumb coat. Might look a little sloppy but at least I showed up with cake! And I didn’t have time to make more frosting for a pretty boarder or decorating.

Rainbow layer cake for St. Patty's Day

So I went simple. I’ve heard that simple is better!

I adorned it with  a green ribbon and sprig of mint.

Alex, my five year old, is really into rainbows right now. He’d absolutely love a piece of this! It turned out absolutely beautiful, shorted layers and all. :)

Interesting!! Beside the good ingredients, I think color also can be one of the important fact.

Awesome cake! I’m a little icing-cake-challenged (gotta wait until it cools!) but this is worth a try!

26 Elle March 28, 2011 at 8:08 am

28 The Lucky Wife @ The Saturday Evening Pot April 1, 2011 at 12:47 pm

Thanks for linking this one in the For Your Sweet Tooth linky at the end of the Mom-Friendly Recipes post. I meant to ask you about including it in the post itself, but I got it confused with someone else that I had not heard back from! I loved this one and thought it was perfect, too, so I’m glad you came back to link it there. :)

29 Cheri Sicard May 3, 2011 at 10:03 am

What an unusual cake. I’ve never seen anything like it. I know some kids would just go crazy for this. Looks like it would be perfect for a circus themed birthday party!

30 Tiffany@Lattes&Life May 17, 2011 at 10:49 am

I’ve had this on my mind ever since you first posted it a few years ago. Just wanted to let you know it will make it’s appearance in a few weeks when my oldest graduates from HIGH SCHOOL! Can you believe it?!?! She loves rainbow anything, so I know your cake will be perfect!

31 Pudding Pie Lane May 18, 2011 at 1:34 am

Wow wow wow this is amazing! No worries about the crumb coat, I couldn’t tell :) Also, just wondering how much food colouring you had to put in for the colour to stay after you baked it?

32 Megan May 19, 2011 at 8:42 am

I put a couple good squirts in it till I got a bright shade that suit my fancy. I wasn’t shy with the food coloring!

33 Shelby June 25, 2011 at 5:40 pm

STUNNING cake!! the colors are so vibrant..which brand of food coloring did you use if you don’t mind sharing? haha

34 Jane October 2, 2012 at 7:19 pm

Hi there, I want to make one of these for my daughter’s first birthday next week and am debating what icing to use. So did this combination taste good? Not too sickly? Do you think using only buttercream’d be too rich? I don’t want to make something that looks amazing but people don’t finish!

35 Felicia Elisara December 7, 2012 at 1:25 pm
