Equipment

  • Mixing Bowl
  • Stand Mixer
  • Cake Pans
  • Wire Rack

Ingredients

Dry Ingredients

  • 2.5 cups All-purpose flour
  • 2.5 teaspoons Baking powder
  • 0.5 teaspoon Salt

Wet Ingredients

  • 1 cup Unsalted butter, softened (room temperature)
  • 2 cups Granulated sugar
  • 4 large Egg whites (at room temperature)
  • 1 tablespoon Vanilla extract
  • 1 cup Whole milk (room temperature)

Coloring and Flavoring

  • Pink food coloring (gel or liquid)
  • Blue food coloring (gel or liquid)
  • 0.5 teaspoon Cotton candy extract (optional)

Instructions

  • Preheat the oven to 350°F (175°C). Grease and flour two 8- or 9-inch round cake pans, tapping out any excess flour.
  • In a medium bowl, whisk together the flour, baking powder, and salt until evenly combined.
  • In a larger mixing bowl, beat the softened butter and granulated sugar on medium speed until light and fluffy, about 3–5 minutes.
  • Add the egg whites one at a time, mixing well after each addition. Mix in the vanilla extract until smooth.
  • With the mixer on low, alternately add the dry ingredients and milk to the butter mixture, starting and ending with the flour mixture. Mix just until combined.
  • Divide the batter evenly into two bowls. Add pink food coloring to one bowl and blue food coloring to the other, mixing until evenly incorporated.
  • Pour the pink and blue batters into the prepared pans in alternating spoonfuls or layers. Use a skewer to gently swirl the batters.
  • Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
  • Remove cakes from the oven and let them cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely before frosting.
  • Once cooled, frost with cotton candy-flavored frosting and decorate with cotton candy, sprinkles, or edible glitter.

Notes

Store the frosted cake in an airtight container in the refrigerator for up to 4 days.
