Ingredients
Scale
- 2 boxes White Cake Mix
- 2 cups Water
- 1 cup Vegetable Oil
- 6 large eggs
- Rainbow Colors of Gel Food Coloring
- 2 cups Butter (softened)
- 2 tsp Clear Vanilla Extract
- 8 cups sifted Confectioners Sugar
- 4 Tbsp Milk
- Rainbow Sprinkles (optional)
Instructions
- Preheat the oven to 350 degrees Fahrenheit and spray 3 (8 inch) round cake pans with a non-stick cooking spray.
- In a large bowl, beat with a hand held mixer or a stand up mixer the cake mixes, water, oil and eggs until the mixture is smooth and creamy.
- Then divide the batter evenly into 6 small bowls (should be approximately 1 1/2 cups of batter in each bowl). Use the gel food coloring to dye each bowl of icing a different color of the rainbow.
- Refrigerate 3 colors of the batter and pour the remaining 3 colors each into a separate baking pan.
- Bake for 18-20 minutes until a toothpick inserted into the middle of the cake comes out clean.
- Let the cakes cool for 10 minutes and then carefully remove from the pans and allow them to cool completely on wire racks.
- Wash the cake pans. Re-spray for non-stick cooking spray and pour the remaining colors of the batters into the pans. Bake the same as you baked the 1st 3 colors. Let them cool completely.
- In a large bowl cream the butter until smooth.
- Beat in the confectioners sugar (one cup at a time) on low speed until well combined.
- Stir in vanilla and milk. Whip until thoroughly mixed and fluffy on a medium-high setting.
- Use a serrated knife to trim the cake layers to make sure that both of the cakes are leveled.
- Place the purple cake on a large plate or cake stand.
- Spread a layer of the frosting on top of this cake.
- Repeat this process with the blue, green, yellow, orange and red cakes.
- Then frosting the sides of the cake and decorate the top as desired with the rainbow sprinkles.
- Then the cake is ready to slice, serve and enjoy!
