Create a fun and spooky treat with these Glow-in-the-Dark Rice Krispies Treats, perfect for Halloween or any fun gathering!

In a microwave-safe bowl, melt the butter and marshmallows together in the microwave for about 1-2 minutes, stirring halfway through until smooth.
Add the tonic water and a few drops of green food coloring to the melted mixture, stirring until well combined.
Gradually add the Rice Krispies cereal to the mixture, stirring until all the cereal is evenly coated.
Press the mixture into a greased 9×13 inch baking pan, making sure it is evenly spread out.
Allow the treats to cool for about 30 minutes before cutting them into squares.
To see the glow effect, turn off the lights and expose the treats to a black light!
