2 boxes white cake mix
1 c. water
2/3 c. oil
Wilton Icing colors in red, orange, yellow, green, blue and purple
(you can use whatever colors you want)
In a large bowl, combine cake mix, eggs, water, and oil together. Scoop 1 cup of batter into six small bowls. In the first bowl, mix red coloring. In the second bowl, mix orange coloring. In the third bowl, mix yellow coloring. In the fourth bowl, mix green coloring. In the fifth bowl, mix blue coloring. In the sixth bowl, mix purple coloring.Prepare six 8 inch cake pans by greasing and flouring each generously. Using a spatula, spoon and spread each color of batter into its own cake pan. Bake in an oven, preheated to 350 degrees for 17-20 minutes, or until tops spring back when touched lightly. Allow to cool completely. Frost a light layer of frosting between each cake layer.
I frosted with a buttercream frosting but I added cream cheese.
2-6 oz cream cheese (depending on your taste)
a few tbsp milk
about 4 C. powdered sugar
1 tsp vanilla or another extract
Mix together and add coloring if desired then frost.
