Need some happiness in the form of a Rainbow Layer Cake? I think yes! Made with six colorful layers and a buttercream icing. The perfect celebration birthday cake.
I took two white cake mixes and mixed them up in a large bowl according to the directions on the box.
Divide the batter into 6 different bowls. Each bowl ended up with about 1 and 3/4 cups of batter each.
Mix some food coloring into each bowl to get my rainbow colors. I used the gel food colors rather than the liquid drops.
When each color is mixed, place batter into 6 separate round 9 inch pans. I only had three, so I baked 3 first and then when they had cooled, I transferred the cakes to a cookie sheet. I washed the pans and baked the other 3 cakes. Be sure to grease your pans well so that the cakes come out without sticking. I baked the cakes in a 350 degree oven for about 12 minutes.
After all the cake layers have cooled, place your bottom layer (purple) onto your cake plate. Add a thin layer of frosting. Place your blue cake layer on top of the frosting. Continue in this manner until you have added all your cake layers.
