Ingredients

Scale
  • 2 boxes white cake mix
  • 6 large eggs
  • 2/3 cup canola oil
  • 2.5 cups water
  • Wilton Gel Food Coloring (assorted colors)
  • 1 cup unsalted butter (room temperature)
  • 4 tbsp milk (dairy or non-dairy)
  • 4 tsp clear vanilla extract
  • 4 cups powdered sugar

Instructions

  1. Preheat your oven to 350°F (175°C). Prepare three 9-inch round cake pans by greasing them and lining the bottoms with wax paper.
  2. In a large mixing bowl, combine the white cake mix, eggs, canola oil, and water. Mix until smooth.
  3. Divide the batter evenly into separate bowls based on how many colors you want. Add gel food coloring to each bowl to achieve desired hues.
  4. Pour each colored batter into the prepared pans and bake for 8-12 minutes or until a toothpick inserted comes out clean.
  5. Allow cakes to cool in pans for about 10 minutes before transferring them to cooling racks.
  6. For the buttercream frosting, beat room temperature butter until creamy, then gradually add powdered sugar, milk, and vanilla extract until smooth.
  7. Assemble your cake by placing one layer on a serving platter, spreading buttercream between layers, and stacking them up.
  8. Frost the entire cake with a crumb coat first, then chill it in the refrigerator for about 30 minutes before applying a final layer of frosting.
