You don’t need any fancy science kit to make these. A splash of tonic water and some neon gelatin powder is all it takes to give these treats their otherworldly glow. The best part?

Why You’ll Love This Glow in the Dark Treat

These aren’t just your average crispy squares. The chewy texture and nostalgic flavor are still front and center, but the addition of glowing magic takes them to the next level. They’re quick to make, require no baking, and look like something straight out of a wizard’s kitchen. Plus, with a few glow sticks and a UV light, your kitchen can transform into a glowing dessert lab.

Can You Really Eat Something That Glows?

Yes! The glow comes from quinine in tonic water and the brightness of neon gelatin powders. Both are totally safe and edible, and while the tonic water doesn’t make the treats glow vividly on its own, it adds to the effect when combined with blacklight-reactive gelatin. Think of it as the secret potion behind your spellbinding snack.

Ingredients for the Glow in the Dark Rice Krispies Treats

Creating these magical snacks doesn’t require any complicated tools or rare ingredients. You likely already have most of what you need, and a quick grocery run will handle the rest.

• Mini marshmallows: These melt down smoothly and give the treats that classic gooey texture we all love.
• Rice Krispies cereal: The signature crunch and structure for your treats.
• Butter: A must-have to add richness and help everything melt together without sticking.
• Tonic water: This is the glow-maker. The quinine it contains makes your treats pop under blacklight.
• Neon gelatin powder (blue, green, or pink): Not only does it provide bright color, but many neon gelatins glow under UV light.
• Vanilla extract (optional): Adds a little warmth and depth to the flavor profile.

How To Make the Glow in the Dark Rice Krispies Treats

Step 1: Prep Your Pan

Line a 9×13-inch pan with parchment paper or lightly grease it with butter. Set aside.

Step 2: Melt the Base

In a large saucepan over medium heat, melt the butter. Once fully melted, stir in the tonic water and mini marshmallows, mixing continuously until everything is smooth and gooey.

Step 3: Add the Glow

Sprinkle in your choice of neon gelatin powder and stir well until fully dissolved. This will tint your mixture and help it react to blacklight later.

Step 4: Mix in the Cereal

Remove from heat and quickly stir in the Rice Krispies cereal until fully coated in the marshmallow mixture.

Step 5: Press and Cool

Pour the mixture into your prepared pan. Use a spatula (lightly greased or with parchment) to press down evenly. Let it cool completely before cutting into squares.

How to Serve and Store These Glow Treats

Glow in the Dark Rice Krispies Treats are best served under a blacklight for the full wow factor. They’re great for parties, Halloween snack tables, or even fun family movie nights. Just set up a blacklight in the room and watch the treats come to life.

This recipe feeds around 12 to 16 people depending on how big you cut the squares. Store leftovers in an airtight container at room temperature for up to 3 days. If your space is humid, place wax paper between layers to prevent sticking.
