How to make Rainbow Cake Recipe

We had a birthday this weekend. In our family, there is a good chance there is a birthday on any given weekend between us, my siblings and extended family!

It was for the little one and so I thought that Rainbow Cake would fit the personality!

I had made rainbow cupcakes a few times, but wanted to tackle the cake.

I used 3 white cake mixes to make the 6 layers. I also didn’t use the egg yolks so that the cake was whiter. I added 2 cups of batter to 6 bowls.

Then I made the kids leave and added all the food coloring… I have stains on clothes from previous cupcakes as justification for making kids leave 🙂 Stir it in good.

I used regular cheap food coloring, and made purple, orange and green by mixing colors.

Grease and flour your pans good. I had 4, 9 inch round pans, so I did 4 and then had to do 2 when those were done. Use the straight side pans and not the ones that are angled like pie plates.

You can find the pans HERE.

Bake until they are done, about 20 minutes. Then carefully flip them out of the pans. and let them cool completely.

When they are cool, I slice the tops off each layer but the top so they are more flat than puffy in the middle. Plus that is the yummiest part of the cake!

Now, I make my own frosting, I really think it tastes sooooo much better it is worth it! If you use store bought, you will probably need to add some powdered sugar to make it a little thicker or your cake is going to slide around.

Put a little frosting on the plate and start with the purple layer. Then add a thin layer between each color until you get to the top. At this point I had to put my cake in the fridge to get it really cold again. When it was cold and solid, I  pulled it back out and frosted the top and sides.

This was a really tall cake! I don’t think I would want to transport it somewhere or I would really cut down the layers. But when it is done, it is really beautiful! The kids are so excited to cut it open! Even though they saw it made, they were still really giddy about eating it!

Sadly, the child that the cake was for, didn’t make it to the cake eating part…. We saved some for her so she could have it for breakfast! We are awesome parents that way!
