Ingredients

Scale
  • 2 1/2 cups all-purpose flour
  • 1 1/2 cups granulated sugar
  • 3 1/2 teaspoons baking powder
  • 1 teaspoon salt
  • 3/4 cup unsalted butter, softened
  • 1 cup milk
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon cotton candy flavoring (optional, but recommended)
  • 1 cup (2 sticks) unsalted butter, softened
  • 4 cups powdered sugar
  • 1/2 cup milk
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon cotton candy flavoring (optional, but recommended)
  • Blue food coloring
  • Cotton candy
  • Sprinkles

Instructions

  1. Preheat oven to 350Β°F (175Β°C). Grease and flour two 9-inch cake pans.
  2. In a large bowl, whisk together flour, sugar, baking powder, and salt.
  3. Add softened butter and mix until the mixture resembles coarse crumbs.
  4. Gradually add milk and mix until just combined.
  5. Add eggs one at a time, followed by vanilla extract and cotton candy flavoring (if using). Mix until smooth, careful not to overmix.
  6. Divide batter evenly between prepared cake pans.
  7. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  8. Let the cakes cool in pans for 10 minutes before inverting them onto cooling racks to cool completely.
  9. While cakes are cooling, prepare the frosting. Beat softened butter until smooth and creamy.
  10. Gradually add powdered sugar one cup at a time, beating well after each addition.
  11. Add milk, vanilla extract, and cotton candy flavoring (if using), beat until light and fluffy.
  12. Add blue food coloring, a few drops at a time, until desired shade.
  13. Once the cakes are completely cool, level them with a serrated knife if desired.
  14. Place one cake layer on a serving plate or cake stand. Spread a generous layer of frosting over the top.
  15. Place the second cake layer on top of the frosting. Frost the entire cake with the remaining buttercream.
  16. Decorate with cotton candy and sprinkles. For an extra touch, swirl some melted white chocolate before decorating.

Notes

  • Don’t overmix the cake batter. Mix until just combined to avoid a tough cake.
  • Use room temperature butter and eggs for a smoother batter.
  • Ensure cakes are completely cool before frosting to prevent melting.
  • Cotton candy flavoring enhances the overall taste; it’s highly recommended.
  • Decorate with cotton candy just before serving to prevent it from dissolving.
