Rainbow Layer Cake

Right off the bat I will admit that I goofed on the colors for this cake and I am missing the green layer. I'M MISSING THE GREEN LAYER. There, I feel better now. Use your favorite recipe for vanilla buttercream.  While I will use a cake mix for cakes, I don't use pre-made icing. It just doesn't compare to homemade.We made about 6 cups of frosting, making sure to set some aside to tint and garnish the cake with green icing.


Tools for the job:

• 1 cake leveler/slicer
• 1 set of icing colors
• parchment paper
• 9 inch round cake pans
• Piping bag plus tips for frosting the edges of the cake
• Angled spatula for spread frosting
• Cake lifter

I used three boxes of white cake mix which call for using egg whites and no yolks to ensure a whiter color. Prepare your mixes using the ingredients called for, beat, and add in coloring. Bake in a parchment lined 8" or 9" round cake pan that has been sprayed with baking spray. Let cool completely.
