Glow-in-the-Dark Moonlit Cupcakes

Ingredients:

For the Cupcakes:
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup milk
  • 1 tablespoon lemon juice or vinegar (for extra fluffiness)
For the Glow-in-the-Dark Frosting:
  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 3-4 tablespoons tonic water (this makes it glow under blacklight!)
  • A few drops of neon food coloring (optional, for a brighter effect)

Construction:

  1. Prepare the Cupcakes:
    • Preheat oven to 350°F (175°C) and line a cupcake tin with liners.
    • In a bowl, whisk together flour, baking powder, baking soda, and salt.
    • In another bowl, cream butter and sugar until light and fluffy.
    • Add eggs one at a time, mixing well. Stir in vanilla extract.
    • Gradually add dry ingredients, alternating with milk and lemon juice.
    • Divide batter evenly into cupcake liners, filling about 2/3 full.
    • Bake for 18–20 minutes or until a toothpick comes out clean. Let cool completely.
  2. Make the Glow-in-the-Dark Frosting:
    • Beat butter until smooth. Gradually add powdered sugar, mixing well.
    • Stir in vanilla extract and tonic water until smooth and fluffy.
    • Add neon food coloring if desired.
    • Pipe onto cooled cupcakes.
  3. Make Them Glow:
    • Place cupcakes under a blacklight, and the frosting will glow due to the quinine in the tonic water!

Variations:

  • Galaxy Cupcakes: Swirl dark blue, purple, and black food coloring into the frosting for a cosmic effect.
  • Lemon Glow: Add lemon zest and juice to the frosting for a citrusy flavor.
  • Glowing Drizzle: Mix tonic water with a little powdered sugar for a glow-in-the-dark glaze.
  • Moon & Stars: Decorate with edible glitter or star-shaped sprinkles.

Tips:

  • Use a strong blacklight for the best glowing effect.
  • Chill frosting before piping for a firmer texture.
  • For an extra glow, use tonic water in the cupcake batter too!
  • If tonic water taste is too strong, mix it with a little milk before adding to the frosting.
