1. Preheat the oven to 350°F and line two baking sheets with parchment paper.

2. In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy.

3. Mix in the egg, vanilla extract, and cotton candy extract until smooth.

4. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.

5. Gradually add the dry ingredients to the wet ingredients and mix just until a soft dough forms.

6. Divide the dough evenly into two bowls. Tint one portion pink and the other portion blue with gel food coloring.

7. Gently fold white chocolate chips and sprinkles into the dough.

8. Take small pieces of pink and blue dough, press them together, and lightly roll into cookie dough balls.

9. Place the dough balls on the prepared baking sheets, leaving space between each cookie.

10. Bake for 9 to 11 minutes, until the edges are set and the centers still look slightly soft.

11. Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
