Cuisine: American

Prep Time: 10 minutes plus 2 hours to chill 

Cook Time: 1 1/2 hours

Total Time: 3 hours and 40 minutes

Servings: 12




  • 2 1/2 cups heavy whipping cream
  • 1/3 cup powdered sugar
  • 2 containers (8 ounces each) mascarpone cheese

Here’s how to make it: 

  1. Preheat oven to 400 degrees F. Grease six 9-inch round cake pans and dust with flour. 
  2. Sift together flour, baking soda and baking powder.
  3. In a large bowl, beat 3/4 cup plus 2 tablespoons butter, the milk, sugar, egg whites and vanilla extract with an electric mixer until smooth. Stir in flour mixture and then mix until just combined.
  4. Divide cake batter evenly among six bowls. Mix in a different food coloring in each bowl (starting with 1 or 2 drops food coloring per bowl), creating six different colored batters. Add more food coloring if necessary, to reach desired colors.
  5. Bake each cake in the preheated oven, until a toothpick inserted in the center comes out clean, about 15 to 20 minutes. Set aside to cool.

  6. Beat cream in a metal or chilled glass bowl with an electric mixer until stiff peaks form. In a separate bowl, stir together confectioners’ sugar and mascarpone cheese, then fold gently into the whipped cream until smooth.
  7. Spread frosting on each layer of cooled cake, placing one on top of the other. Cover the top and sides with the remaining frosting. Decorate with rainbow sprinkles, if desired. Refrigerate for 2 hours before serving.
