Preheat the oven to 350 degrees F. Line five 6-inch cake pans with parchment paper and coat with cooking spray. Prepare your choice of white cake batter as directed and divide the batter between five bowls.

Add each color of batter to a pan and bake 20 to 25 minutes. Allow the cakes to completely cool before you begin decorating.
