Preheat the oven and line two baking sheets with parchment paper.
Whisk together the dry ingredients.
3 cups all-purpose flour, 2 teaspoons baking powder, ½ teaspoon salt
In another bowl, beat together the butter and sugar. (An electric mixer fitted with a paddle attachment is ideal, but a hand mixer will work also).
1 cup butter, softened, 1 cup sugar
Add the egg and cotton candy extract. Be sure to scrape down the sides of the bowl.
1 egg, 1 ½ teaspoon cotton candy flavoring
Add the dry ingredients to the wet ingredients. The dough will be a little crumbly.
Turn the dough out onto a floured surface and divide the dough into two equal portions.
Knead the pink food coloring into one half of the dough and the blue food coloring into the other half.

Bake for 7-9 minutes at 350 degrees then transfer to a cooling rack.
