Ingredients

Units Scale

Cupcake Batter:

  • 1 box white cake mix (plus ingredients listed on box)
  • 1 cup tonic water (replace equal part of water in cake mix for glow effect)
  • 1 teaspoon vanilla extract

Frosting:

  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 23 tablespoons tonic water
  • Blue and purple gel food coloring

Decorations:

  • Edible silver glitter or sprinkles
  • White chocolate candy melts (optional for moon decorations)

Instructions

  1. Preheat oven and prepare batter: Preheat oven according to cake mix package directions and line a muffin tin with cupcake liners. Prepare cake batter as directed, replacing part of the water with tonic water for a subtle glow under black light. Stir in vanilla extract.
  2. Bake and cool: Divide batter evenly among liners and bake as directed. Cool completely before frosting.
  3. Make frosting: Beat butter until creamy, then gradually add powdered sugar, alternating with small amounts of tonic water until smooth and fluffy.
  4. Tint and frost: Divide frosting into two bowls and tint one blue and the other purple. Swirl the two colors together in a piping bag and frost cupcakes.
  5. Decorate: Sprinkle with edible silver glitter or sprinkles. For optional moon decorations, melt white chocolate candy melts, spread into circles on parchment, and let set before placing on top.
  6. Serve: Serve cupcakes under a black light to reveal the glow effect.

Notes

  • The glow effect comes from quinine in tonic water, which glows under UV light. These cupcakes look normal in regular lighting but have a magical glow for parties.
