Ingredients Equipment Method Notes

Ingredients
  

  • 6 cups Rice Krispies cereal
  • 4 cups mini marshmallows The sticky, sweet binder that holds everything together.
  • 1/4 cup unsalted butter Adds richness and helps everything melt smoothly.
  • 2 tablespoons tonic water This is the secret ingredient that makes them glow under a blacklight!
  • 1/2 teaspoon vanilla extract For that classic, comforting vanilla flavor.
  • Neon food coloring drops neon food coloring (green, blue, pink, or yellow): To give your treats vibrant colors that pop.

Equipment

  • large saucepan
  • 9x13-inch Baking Dish
  • Parchment paper

Method
 

  1. First things first, grab a large saucepan. Melt your unsalted butter over low heat. We want it nice and melted, but definitely not browned. Low and slow is the way to go!
  2. Once your butter is all liquid gold, it’s time to add the stars of the show: the mini marshmallows and the secret glow-up ingredient, tonic water! Keep stirring gently over low heat. You'll see the marshmallows start to puff up and melt into a smooth, gooey mass. Keep stirring until it's wonderfully smooth and there are no pesky lumps left.
  3. Carefully remove the saucepan from the heat. Now, stir in the vanilla extract. This is where that cozy, familiar aroma really starts to fill your kitchen. Make sure it’s all mixed in evenly.
  4. This is the fun part! Add a few drops of your chosen neon food coloring to the melted marshmallow mixture. Start with a little and add more if you want a bolder glow. Stir gently until the color is distributed evenly. You can even make a few batches with different colors for a rainbow effect!
  5. Now, gently fold in your Rice Krispies cereal. The key here is to be gentle so you don’t crush those precious cereal pieces. Make sure every single crispy bit is coated in that glorious, colorful marshmallow goo.
  6. Grease a 9x13-inch baking dish. This is important to prevent sticking! Spoon the cereal mixture into the dish. I like to use a piece of parchment paper over the top and gently press it down to smooth out the surface. This makes for nice, even squares.
  7. Let your creations cool at room temperature for about 30 minutes, or until they’re firm enough to slice. Patience, my friend!
  8. Once they’ve set, slice them into squares. Now you’re ready for the best part – seeing them glow!

Notes

Want to jazz things up even more? You’ve got options! Different Cereals: While Rice Krispies are classic, you could try crispy rice or even a puffed wheat cereal for a slightly different texture. Add-ins: Sprinkle in some colorful candy melts or even white chocolate chips right after pressing them into the pan. Flavor Boost: A little bit of citrus zest (like lemon or lime) can add a lovely brightness to the flavor. For a Stronger Glow: Ensure your blacklight is powerful enough and that the tonic water is fresh!
