Ingredients
Scale
Cupcake Batter
- 1 box vanilla cake mix (or your favorite homemade recipe)
- Eggs, oil, and water (as directed on the box)
Glow-in-the-Dark Frosting
- 1 cup unsalted butter, softened
- 3–4 cups powdered sugar
- 1 teaspoon vanilla extract
- 2–3 tablespoons tonic water (contains quinine, which glows under black light)
- Edible neon food coloring (optional)
- Edible glitter or star-shaped sprinkles
- Black light (to activate the glow)
Instructions
- Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners to prepare for baking.
- Make the Cupcakes: Prepare the cupcake batter according to the package instructions. Divide the batter evenly among the cupcake liners, filling each about two-thirds full. Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and allow cupcakes to cool completely before frosting.
- Make the Glow-in-the-Dark Frosting: In a large mixing bowl, beat the softened butter until creamy. Gradually add powdered sugar, one cup at a time, beating well after each addition to ensure smoothness. Stir in vanilla extract and tonic water until the frosting is smooth and spreadable. Optionally, add edible neon food coloring for vibrant hues that glow under black light.
- Decorate the Cupcakes: Spread or pipe the frosting onto the cooled cupcakes evenly. Sprinkle edible glitter or star-shaped sprinkles on top for a celestial appearance. Test the glowing effect by placing the cupcakes under a black light before serving.
- Serve and Enjoy: Display the cupcakes under a black light to showcase their enchanting glow. Enjoy this magical treat with your guests!
Notes
- Ensure cupcakes are completely cooled before frosting to prevent melting.
- Tonic water contains quinine, which glows under black light; avoid substitutes if you want the glowing effect.
- The black light is essential to activate the glow, so plan to serve in an environment where it can be used.
- Use edible neon food coloring to enhance the glowing effect but avoid non-edible dyes.
- Store cupcakes in an airtight container at room temperature for up to 2 days for best freshness.
- Test the glow before serving to ensure the tonic water concentration is sufficient.
