Preheat your oven to 350°F (175°C). Grease two round cake pans with nonstick spray and dust lightly with flour.

In a medium bowl, whisk together flour, baking powder, and salt; set aside.

In a large mixing bowl, beat softened butter and granulated sugar until creamy (about three minutes).

Add eggs one at a time, mixing on low speed after each addition. Stir in cotton candy flavoring.

Gradually incorporate dry ingredients into the wet mixture, alternating with milk until smooth.

Divide batter into bowls for coloring; add food coloring to achieve desired pastel shades.

Spoon colored batter into prepared pans in layers or swirls. Bake for 25-30 minutes or until a toothpick comes out clean.

Cool cakes in pans for ten minutes before transferring to wire racks. Once cooled, frost generously with whipped frosting.
