Ingredients You’ll Need
The beauty of Glow-in-the-Dark Moonlit Cupcakes is just how easy they are to put together, using a mix of everyday staples and a dash of neon magic. Each ingredient plays a unique role in making the colors bold, the frosting fluffy, and that hidden glowing effect truly pop when the lights go down.
- White cake mix: The perfect blank canvas to make those neon colors shine and keep the cupcakes light and tender.
- Eggs, oil, and water: These are usually called for on the cake mix box and are essential for binding everything and making the cake moist.
- Neon food coloring (green, blue, or purple): Add a wildly fun splash of color—pick your favorites for a kaleidoscope effect!
- Tonic water: The secret ingredient—its quinine creates the glowing effect under black light and adds a subtle tang in the frosting.
- Instant vanilla pudding mix: Gives the frosting structure and an extra creamy vanilla flavor.
- Milk: Smooths out the pudding and keeps the frosting just right for spreading or piping.
- Whipped topping (like Cool Whip): Makes the frosting extra light, fluffy, and easy to swirl on top.
- Glow-in-the-dark cupcake liners (optional): For even more glowing fun and to make your treats pop on any dessert table.
- Edible glitter or sprinkles (optional): For a sparkling moonlit look that ups the wow factor.
How to Make Glow-in-the-Dark Moonlit Cupcakes
Step 1: Prep the Cupcake Liners
Start by preheating your oven to 350°F (175°C) and lining your cupcake tin with glow-in-the-dark or dark-colored liners. The liners aren’t just decorative—they’ll help reflect the glowing colors of your cupcakes for an even cooler effect under black light!
Step 2: Mix and Color the Batter
Prepare your white cake mix following the package instructions, mixing in the eggs, oil, and water to create a smooth, pourable batter. To create that signature Glow-in-the-Dark Moonlit Cupcakes look, divide the batter evenly into separate bowls—one for each color you want to use. Squeeze in your neon food coloring and stir well until each batch turns brilliantly bright and irresistible.
Step 3: Fill and Swirl the Cupcake Liners
Spoon each colored batter into your liners, layering or swirling the colors together (if you like) to make mesmerizing patterns. Each liner should be about two-thirds full, allowing space for the cupcakes to rise. Pop the tray in the oven and bake for 18 to 22 minutes, or until a toothpick inserted in the center comes out clean. Let them cool completely on a wire rack before decorating.
Step 4: Create the Glowing Frosting
While your cupcakes cool, whip up the magical frosting! In a medium bowl, combine the instant vanilla pudding mix, tonic water, and milk. Whisk until the mixture thickens up—this happens quickly, so keep an eye on it. Gently fold in the whipped topping to transform the pudding into a dreamy, airy frosting that will glow gloriously under black light. Chill the frosting for at least 30 minutes so it sets perfectly for swirling or piping.
Step 5: Decorate for Maximum Moonlit Magic
Once the cupcakes and frosting are fully chilled, it’s time to decorate! Dollop or pipe the glowing frosting onto each cupcake. For the finishing touch, sprinkle a little edible glitter or bright sprinkles on top if you’re going all out. For the best dramatic glow, place your Glow-in-the-Dark Moonlit Cupcakes under a black light before serving—and get ready for the oohs and aahs!
How to Serve Glow-in-the-Dark Moonlit Cupcakes

Garnishes
To really lean into the moonlit, enchanted theme, finish your cupcakes with edible glitter, shimmering sprinkles, or tiny edible stars. Not only do they look dazzling under black light, but they make every bite feel like a celebration.
Side Dishes
If you want to keep the party glowing, serve these cupcakes with equally vibrant treats: think fruit punch made with tonic water, neon gelatin cups, or a platter of colorful candy. They pair beautifully with all things bright and lively!
Creative Ways to Present
For maximum impact, arrange your Glow-in-the-Dark Moonlit Cupcakes on a dark tray or cake stand and surround them with LED string lights or glowing decorations. For parties, dim the lights and place a UV black light nearby to make your dessert table shine like a real moonlit night.
Make Ahead and Storage
Storing Leftovers
If you somehow have leftovers, store the cupcakes in an airtight container in the fridge. The frosting will hold up beautifully for up to three days—just keep them chilled so the topping stays fresh and glowy.
Freezing
You can freeze unfrosted cupcakes in a sealed bag for up to two months. When you’re ready to party again, simply thaw them at room temperature, whip up a fresh batch of glowing frosting, and decorate until they shimmer like new.
Reheating
There’s no need to reheat Glow-in-the-Dark Moonlit Cupcakes—just let them come to room temperature or enjoy them chilled right from the fridge. If you do prefer a slightly softer cake, a quick 10-second zap (without frosting) in the microwave will do the trick before decorating.
FAQs
How do Glow-in-the-Dark Moonlit Cupcakes actually glow?
The magic comes from tonic water! It contains quinine, which glows vividly under UV black light. Mixing it into the frosting gives your cupcakes that otherworldly shine perfect for a nighttime celebration.
Can I make Glow-in-the-Dark Moonlit Cupcakes without tonic water?
While the cupcakes will still be delicious and colorful, tonic water is essential for the glowing effect. If you skip it, your topping won’t light up under black light, but you’ll still get vibrant neon cupcakes.
Is the quinine in tonic water safe to eat?
Yes! Quinine has been safely consumed in tonic water for years. It’s present in very small amounts and is FDA approved for use in foods and drink—so you can enjoy your moonlit treats worry-free.
Can I use gel food coloring instead of liquid?
Absolutely! Gel food coloring tends to give even brighter, more intense colors, which are perfect for Glow-in-the-Dark Moonlit Cupcakes. Just add a little at a time until the batter is as neon as you like.
Will all the frosting glow or just certain colors?
The frosting made with tonic water will glow a bluish-white under black light, regardless of color. Pair it with neon-colored cupcakes for a double hit of glow—and go wild with garnishes to make the effect even cooler!
Final Thoughts
There’s nothing like seeing a tray of Glow-in-the-Dark Moonlit Cupcakes lighting up the night and sparking pure joy in every guest. If you’ve never tried making glowing desserts before, this is the most fun—and tasty—way to start. Give them a whirl for your next party, and watch these magical cupcakes become everyone’s new favorite treat!
