Ingredients

Scale
  • 2 1/2 cups all-purpose flour
  • 1 tbsp baking powder
  • 1/2 tsp salt
  • 1 cup unsalted butter, room temperature
  • 1 3/4 cups granulated sugar
  • 4 large egg whites
  • 1 tbsp vanilla extract
  • 1 cup whole milk
  • Pink and blue food coloring
  • 1 1/2 cups unsalted butter, room temperature (for buttercream)
  • 4 1/2 cups powdered sugar, sifted
  • 23 tbsp whole milk or heavy cream
  • 1 1/2 tsp cotton candy flavoring
  • Pinch of salt
  • 1/2 cup reserved buttercream (for filling)
  • 1 tsp extra cotton candy flavoring (optional)
  • Extra food coloring for vibrant swirls (optional)
  • Edible glitter or small tufts of cotton candy (for decoration)

Instructions

  1. Preheat the Oven: Set your oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, and salt.
  3. Cream Butter and Sugar: In a large mixing bowl, cream the butter and sugar together on medium-high speed for 3-4 minutes until pale and fluffy.
  4. Add Egg Whites: Add the egg whites one at a time, beating well after each addition. Stir in the vanilla extract.
  5. Combine Dry and Wet Ingredients: Add the dry ingredients in three additions, alternating with the milk, mixing just until combined.
  6. Divide the Batter: Divide the batter evenly into three bowls. Leave one uncolored, tint one with pink, and the last with blue food coloring.
  7. Bake: Bake for 25-28 minutes, or until a toothpick comes out clean. Cool the cakes in the pans for 10 minutes before inverting onto wire racks.
  8. Make the Buttercream: Beat the remaining butter until smooth, then gradually add the sifted powdered sugar, milk, cotton candy flavoring, and pinch of salt; beat until smooth.
  9. Prepare the Filling: Reserve 1/2 cup of buttercream, tint the remaining with pink and blue food coloring.
  10. Create the Filling: Mix the reserved buttercream with more cotton candy flavoring if desired, swirl the pink and blue together.
  11. Assemble the Cake: Layer the uncolored cake, spread with the marbled filling, add the pink layer, repeat, and top with the blue layer.
  12. Frost the Cake: Apply a crumb coat with plain buttercream, chill for 20 minutes, then apply the final pastel frosting layer.
  13. Decorate: Add pink swirls and edible decorations before serving.
