Ingredients
Scale
Cupcakes
- 1 ½ cups all-purpose flour
- 1 ½ tsp baking powder
- ¼ tsp salt
- ½ cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 2 tsp vanilla extract
- ½ cup whole milk
- 1 tbsp tonic water (for the glow effect)
Frosting
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- 2 tbsp whole milk
- 1 tsp vanilla extract
- 2 tbsp tonic water (for the glow effect)
- Blue or purple food coloring (optional)
Instructions
- Prepare the Cupcakes: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners. In a medium bowl, whisk together the flour, baking powder, and salt to combine the dry ingredients. In a separate bowl, cream together the softened butter and granulated sugar until light and fluffy. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract. Gradually add the dry ingredients to the wet mixture, alternating with the milk, and mix gently until just combined. Finally, fold in the tonic water to introduce the glow effect.
- Bake the Cupcakes: Spoon the batter evenly into the prepared cupcake liners, filling each about two-thirds full to allow room for rising. Bake the cupcakes in the preheated oven for 18 to 20 minutes, or until a toothpick inserted in the center comes out clean. Remove from the oven and let the cupcakes cool completely on a wire rack before frosting.
- Make the Frosting: In a mixing bowl, beat the softened butter until smooth and creamy. Gradually incorporate the powdered sugar, followed by the milk and vanilla extract, beating continuously until the frosting becomes fluffy and spreadable. Stir in the tonic water carefully, adjusting the amount to achieve the desired glow and consistency. If desired, add blue or purple food coloring to enhance the visual effect.
- Frost the Cupcakes: Once the cupcakes are completely cool, generously frost each one with the glow-in-the-dark frosting using a spatula or piping bag. The tonic water in the frosting will make it glow under a UV light or blacklight, creating a captivating moonlit effect.
- Serve and Enjoy: Present the cupcakes under a blacklight to showcase their glowing frosting. These cupcakes make an enchanting centerpiece for parties and will delight guests with their luminous charm.
Notes
- For best glowing effect, serve cupcakes under a UV or blacklight.
- Do not substitute tonic water as its quinine content causes the glow.
- Ensure cupcakes are fully cooled before frosting to prevent melting.
- Optional food coloring enhances the luminous moonlit theme but is not necessary for the glow.
- Store frosted cupcakes in an airtight container at room temperature for up to 2 days.
