  • 1 cup unsalted butter softened
  • 1.5 cups granulated sugar
  • 1 large egg room temperature
  • 1 tsp vanilla or almond extract
  • 2.5 cups all-purpose flour
  • 0.5 tsp baking powder fresh
  • 0.25 tsp salt or sea salt
  • 0.25 cup cotton candy powder
  • 1 tsp food-grade quinine powder
  • 0.5 cup tonic water

Equipment

  • Oven
  • Baking Sheet
  • Parchment Paper

Method
 

  1. Step 1: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. Step 2: Cream together the softened butter and granulated sugar using a hand mixer or stand mixer until light and fluffy, about 2-3 minutes.
  3. Step 3: Add the room temperature egg and vanilla or almond extract to the butter mixture and mix until fully combined.
  4. Step 4: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.
  5. Step 5: Gradually add the dry flour mixture into the wet ingredients, stirring gently until just combined. Avoid overmixing.
  6. Step 6: Stir in the cotton candy powder, food-grade quinine powder, and tonic water until the dough is evenly blended.
  7. Step 7: Shape the dough into 1-2 tablespoon sized balls or use cookie cutters for festive shapes, placing them evenly spaced on the prepared baking sheet.
  8. Step 8: Bake for 10-12 minutes until the edges turn light golden and the centers remain soft.
  9. Step 9: Cool the cookies completely on a wire rack before moving them to allow them to set.
  10. Step 10: Turn off the lights and enjoy the magical glow of your cookies in a dark room.

Notes

Use room temperature ingredients for best results. Chill dough if too sticky before shaping. Store cookies in an airtight container at room temperature for up to 4 days, refrigerate for up to a week, or freeze for up to 3 months. Charge cookies under bright light before turning off lights to enhance glow. Substitute extracts or add sprinkles and edible glitter for extra fun.
