Instructions
Butter a large rimmed sheet pan. Set aside.
Add Rice Krispies to a large mixing bowl. Set aside.
In a 4-quart (or larger) saucepan or Dutch oven over medium-high heat, melt the butter and marshmallows, stirring occasionally until it is a smooth, thick mixture.
Add in the candy melts, peppermint extract, and food gel coloring. Stir to combine, using more gel color if necessary, until you have your desired color.
When the mixture is completely melted, remove saucepan from the heat. Pour it over the Rice Krispies. Using a wooden or silicone spoon, gently stir the mixture until all of the cereal is coated.
Pour the Rice Krispies treat mixture onto the sheet pan. Using buttered hands (to prevent the mixture from sticking), or a silicone spatula, spread the mixture into an even layer on the pan. Let the marshmallow treats cool completely, 30 to 60 minutes.
Decorating the Santa's Hats
Once cool, use a Santa hat cookie cutter to cut out 12 crispy rice treats.
Pipe a wave of royal icing on the bottom edge of the hat, and a circle on the top. Then place a marshmallow on the circle and 5 marshmallows along the bottom edge. Continue until every hat is decorated. Note: You can use any leftovers to create balls, ornaments, etc.
Serve and enjoy.
Notes
Spreading the marshmallow mixture out onto the pan is the easiest if you butter your hands first. Alternatively, you can cover the mixture with a sheet of parchment or wax paper and press down on that to spread the mixture out.
