Preheat your oven to 350°F (175°C) and grease three round cake pans.

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

In a separate bowl, cream softened butter and sugar until fluffy. Add eggs one at a time while mixing well.

Mix in cotton candy flavoring and milk until smooth. Add food coloring for desired pastel hues.

Gradually combine dry ingredients with wet mixture until just blended.

Divide batter evenly among prepared pans and bake for 25-30 minutes or until a toothpick comes out clean. Cool completely before frosting.
