Ingredients
Scale
For the Cupcakes:
- 1 box white or vanilla cake mix (plus ingredients listed on box)
- 1 tablespoon lemon or lime zest (optional, for extra brightness)
- Neon or glow-in-blacklight food coloring (green, blue, or purple)
For the Frosting:
- 1 cup unsalted butter (softened)
- 3–4 cups powdered sugar
- 1/4 cup tonic water (contains quinine for glow effect)
- 1 teaspoon vanilla extract
- Neon food coloring (to match your theme)
- 1–2 tablespoons heavy cream (as needed for texture)
For Decoration:
- Glow-in-the-dark candy stars or sprinkles (UV-reactive)
- Silver sprinkles or edible glitter
- Cupcake liners (dark or metallic for contrast)
Instructions
- Prepare Cupcake Batter: Preheat your oven according to the cake mix instructions. Prepare the cupcake batter as directed on the box, adding in lemon or lime zest if desired for extra brightness. Incorporate neon or glow-in-blacklight food coloring, mixing well to achieve a vibrant color.
- Bake Cupcakes: Divide the batter evenly into cupcake tins lined with dark or metallic cupcake liners. Bake as instructed on the cake mix box, typically around 20 minutes, or until a toothpick inserted comes out clean. Let the cupcakes cool completely before frosting.
- Make the Frosting: In a mixing bowl, beat the softened butter until creamy. Gradually add in the powdered sugar, beating until the mixture is fluffy. Pour in the tonic water and vanilla extract, then add neon food coloring to match your cupcake theme. Adjust the texture as needed by incorporating additional powdered sugar or heavy cream until smooth and pipeable.
- Frost the Cupcakes: Using a piping bag or spatula, frost the cooled cupcakes evenly with the tonic water frosting. Work carefully to create a smooth or decorative surface.
- Decorate: Garnish the frosted cupcakes with glow-in-the-dark candy stars, UV-reactive sprinkles, and a sprinkle of silver edible glitter to enhance the moonlit glowing effect.
- Serve: For the best glowing experience, place the cupcakes under a blacklight in a dark room just before serving to showcase their luminous beauty.
Notes
- Tonic water glows under blacklight due to quinine and is safe and flavor-neutral in the small amount used here.
- You can enhance the moonlit theme by adding glow-in-the-dark cupcake toppers or picks.
- Ensure cupcakes are completely cooled before frosting to prevent melting or sliding of frosting.
- Use dark or metallic cupcake liners to maximize the contrast and glowing effect.
