Ingredients

Scale
  • 1. 2 1/2 cups all-purpose flour
  • 2. 1/2 tsp baking powder
  • 3. 1/4 tsp salt
  • 4. 3/4 cup unsalted butter, softened
  • 5. 1 cup granulated sugar
  • 6. 1 large egg
  • 7. 2 tsp cotton candy flavoring
  • 8. 2–3 drops pink or blue food coloring
  • 9. 1/4 cup milk
  • 10. 2 cups powdered sugar (for icing)
  • 11. 1/4 cup tonic water (for glow effect)
  • 12. Gel food coloring (neon shades work best)
  • 13. Edible glitter or sprinkles (optional)

Instructions

  1. Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  3. In a large bowl, cream butter and granulated sugar until light and fluffy.
  4. Beat in the egg, cotton candy flavoring, and food coloring until well combined.
  5. Gradually add dry ingredients, alternating with milk, mixing until a soft dough forms.
  6. Roll dough into small balls and place on prepared baking sheets.
  7. Bake for 8–10 minutes or until edges are just set. Cool completely before icing.
  8. For icing, whisk powdered sugar and tonic water until smooth. Divide into bowls and tint with neon gel colors.
  9. Dip cooled cookies into icing or drizzle over tops. Sprinkle with edible glitter if desired.
  10. For best glow effect, display cookies under a black light before serving.

Notes

  • Tonic water’s quinine is what makes the icing glow under black light.
  • Use gel food coloring for vibrant, party-ready colors.
  • Cotton candy flavoring can be found online or in specialty baking shops.
  • Store cookies in an airtight container for up to 5 days.
