Equipment

  • 12-cup cupcake tin
  • Cupcake liners
  • Mixing bowls
  • Electric mixer (optional)
  • Measuring cups and spoons
  • Piping bag and tips (optional)
  • Small paintbrushes (for decorating)

Ingredients
  

For the Cupcakes:

  • 1 box white cake mix plus ingredients called for on the box, such as eggs and oil
  • ¼ cup tonic water added to the batter for a subtle glow

For the Glow-in-the-Dark Frosting:

  • 8 ounces cream cheese softened
  • ½ cup 1 stick unsalted butter, softened
  • 4 cups powdered sugar
  • 1 teaspoon vanilla extract
  • ¼ cup tonic water or more, to adjust consistency
  • Edible glow-in-the-dark food gel optional, for a brighter glow

For the Moonlit Design:

  • Blue food coloring
  • Black food coloring
  • White decorating gel

Instructions
 

  • Prepare Cupcake Batter: Preheat oven to 350°F (175°C). Line a 12-cup cupcake tin with liners. Prepare the white cake mix according to the package directions, adding 1/4 cup of tonic water to the batter.
  • Bake Cupcakes: Fill the cupcake liners about 2/3 full. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
  • Cool Completely: Let the cupcakes cool completely in the tin before frosting.
  • Make the Frosting: In a mixing bowl, beat the softened cream cheese and butter until smooth and creamy. Gradually add the powdered sugar, mixing on low speed until combined. Stir in the vanilla extract and 1/4 cup of tonic water. Add edible glow-in-the-dark food gel (if using) to enhance the glow.
  • Tint Frosting: Divide the frosting into three bowls. Tint one bowl with blue food coloring, one with black food coloring, and leave one bowl white.
  • Frost Cupcakes: Frost the cupcakes with the tinted frostings, creating a moonlit sky effect. You can use a piping bag and tips for a more elaborate design, or simply spread the frosting with a knife.
  • Add Details: Use white decorating gel to add details like stars, clouds, or a crescent moon.
  • Glow Time: To see the glow, turn off the lights and shine a black light on the cupcakes!
