Rainbow Cake-How To

A few weeks ago, the Pioneer Woman had a food photo contest. Someone entered a picture of a rainbow cake that they made and when I saw it, I knew I wanted to make one for Judah's party. His party was a Mickey Mouse theme and although it didn't really fit the theme, I thought it'd be fun for a kids birthday party.

So, I googled "Rainbow cake" and came across a recipe featured on Martha Stewart's website. The recipe can be found HERE. I called my sister to see if I could borrow some cake pans from her and to see what colors of food coloring she had. With her purple food coloring and some colors that I already had, I had all the colors that I needed. Hooray! Time to make the cake!

Judah's party was on Saturday. I like to try and be prepared so, I made the cake on Thursday. Actually, I made the FIRST cake on Thursday. Step #1 in the directions says "Brush six 9-inch-round cake pans (or as many 9-inch cake pans as you have, reusing them as necessary) with shortening. Line bottom of each cake pan with parchment paper; brush again and set aside."

Well, I thought that I could just grease and flour the pans well and that would be good enough. Wrong! I put 4 pans of cake into the oven and I couldn't get any of them to come out of the pan in one piece.
So, I tasted the chunks of cake that came out of the pans (yum!) and then scraped the pans of pretty colored cake into the garbage can. I'm not sure if my trash can has ever looked that colorful! I did my dishes and decided to try again on Friday.

Round number two........

I traced the bottom of 6 cake pans and cut out 6 circles of parchment paper. I followed the directions this time and it worked great. I also baked the cake ONE cake pan at a time. The first time around, when I baked 4 at a time, they didn't seem to bake evenly. They turned out so much better when they were baked individually.

Making this cake and coloring the cake batter was so fun. I just love the colors. Please excuse these pictures, they are all from my cell phone. I was sending them to my sister while I was baking because, she's nice and she cares. :)
Here's the orange, right out of the oven.
Green and purple, cooling on racks.
Yellow, ready to go into the oven. Orange and red-waiting to get put into a cake pan.
Green and blue-ready to be baked.
I let them cool for a few hours and then I made the butter cream frosting from the recipe. First you make a Filling & Crumb Coat. You frost the cake with it, then the cake chills for at least 30 minutes. Then you make a frosting and frost the cake. The directions explain about the 2 butter cream frosting's.

I'd never made a butter cream frosting before. Holy cow, it calls for a lot of butter. For the cake, the crumb coat and the frosting, you use a total of 8 sticks of butter. Isn't that crazy!

The frosting was harder to make than I thought it'd be. You have to beat it for soooooo long. It turned out really yummy though. I spread the crumb coat on the cake like the directions explain and after the cake chilled, I piped the frosting on. I love piping frosting, it was so fun! Here is the finished cake:
After the cake was done, we kept it in the garage in a plastic container until the party. The frosting calls for so much butter that I was afraid it would melt if it was room temperature for too long. Keeping it cold seemed to work really well.
Now I'm kinda sad that my cake making experience is over, for now. I had so much fun and I can't wait to make one of these cakes again!


  1. OMGosh! Such a cute idea. My baby Ella will be turning 1 in March and I might have to try this in cupcake form (I have had her party planned since she was a month old lol) Thanks for sharing!!

  2. You're welcome! Doing this with cupcakes would be so cute! Let me know how it turns out!

  3. I've tried it with cupcakes before. While very cute, it is too time-consuming and difficult. You have to very thinly layer each color in each muffin tin.

    1. We did this with cupcakes and instead of layering the batter, we scooped it into the muffin tins with spoons, using random colors. This was very easy for my small children to do. Since the layers are not even after baking, we just called them tye-dyed. Also, each child got to pick which colors she did or did NOT want in her cupcake. They were extremely cute and he kids LOVED them.

  4. Yours looks SO much better than mine! I guess separating the colors is key. : )

  5. Thanks so much for sharing, Angela! You did such a fabulous job on this cake ~ I LOVE it!!

  6. I'm here because of seeing this wonderful cake on The Frugal Girls email. Hannah, my middle daughter) is turning 6 in a few weeks and I need to decide on a cake. I'm going to show her this one. Thanks!

    It's always fun to find another blog to check out. I'm also a Christian, a wife and a mom (of 4 kids, ages 7 to 2).

    In your profile you said, "My entire life I've dreamed of being married, having babies and being a house wife. Although it's not always easy, I feel like this is where God wants me to be." I had to smile because that sound exactly like me! :)

    Anyway, thanks again for sharing. I think Hannah will be excited about having this for her cake!


  7. Hi Sarah,
    Thanks for the comment and welcome to my blog! So, you're the mom of 4kids....that's awesome and amazing! I'll be there someday but for now, two little ones are keeping me pretty busy! Let me know what your daughter thinks about the cake.

  8. I want to try this soooooo badly! Great job with it. Looks tasty too! :)

  9. Angela,
    I thought I would get back with you about the cake. I did make it for Hannah's 6th birthday, which was yesterday. It turned out wonderful and She loved the colors!

    However, the frosting was a little rich for us, so I'm thinking about trying another kind of frosting the next time I make it.

    Thinking ahead... Another of my kids is a huge chocolate fan and my Mom makes a cake with whip cream as a filling. So, I'm not sure what will work, but I may do some experimenting! :)


  10. This cake always look super impressive!
    It's not difficult to make although it looks very complicated :)
    Everyone would loooooooooove to have it for his birthday


Thank you for your comments. I read every single one of them and they always make me smile.
