How to make Monster Rice Krispies

Unwrap the treats and lay them out on parchment paper or a plastic cutting board.

Pour your sprinkles into a wide bowl or onto a plate and place them in your prep area.

Melt the candy melts in a medium microwave-safe bowl. Microwave them for 15-second intervals, stirring in between, until the candies are completely melted and smooth.

Dipping a rice crispy treat into melted green candy.

Quickly add as many candy eyes as you wish to create your monster, and place the treat down on your parchment paper.

Make sure to do this while the candy is still wet, so the eyes stick well.
