Fun and Easy Rainbow Cake

I made Shelby’s smash cake for her one year photos and it was a lot of fun to make!  The Omnomicon has a fabulous step-by-step Rainbow Cake tutorial which I used and the cake came out great! The frosting on the other hand, tasted great but was droopy and we had to keep the cake in the freezer so the frosting wouldn’t fall off the cake. Not sure if I did it wrong but non the less the cake was perfect for the photos!

Below is all the ingredients needed for the cake. instead of the egg and oil you replace the soda. he soda made for a really yummy moist cake! The jello is for the frosting so you really don’t need it unless you want to make the frosting too.

Just mix the cake mix and soda together!

You will have a total of approximately 64 ozs.  I split it all as evenly as I could into six different bowls. It was about 1 and a half cups total in each bowl. I used regular food coloring and the colors were bright and perfect.

When you have all your colors then you can start putting them into your GREASED cake pan!!! I used 3/4 cups of each color, but you cna do it any way you like depending on if you want more of one color than another.

If you started with red on your first cake, start with purple on your second so when the cakes are done they are opposite!

Since you used soda, you should cook it about 6-8 minutes longer! Also, when it’s done I noticed the cake was stickier than other cakes, so be careful on how you let it cool down! I used a non-stick bake liner and it stick like crazy!!!!

 

I did keep the cakes in the freezer so that it would be easier to frost in the morning!

I didn’t share the frosting because quite frankly I was not a fan of it. But if you want to try it out you can at Rainbow Cake tutorial.
