Melt candy melts according to directions, using different bowls for different colors.

Line the bottom of each silicone square with melted candy.

Make rice krispie treats on the stove: melt 4 Tbsps of butter in large pot, when butter's melted, add entire bag of marshmallows on medium heat. Stir until marshmallows have melted. Add 5 cups of rice krispie cereal. Stir until evenly mixed.

Fill silicone squares with rice krispie treat mixture and allow to cool.

Once cooled, they'll pop out of the silicone mold and be ready to eat!
