Alternate Method: You can also make the bottom peppermint layer with chocolate chips! Melt a bag of chocolate chips, a teaspoon or two of coconut oil, and a teaspoon of peppermint extract (or 1/4 teaspoon of peppermint oil) in the microwave in 30-second intervals until melted and smooth. Dip the cookies in chocolate and set them on wax or parchment paper-lined baking sheets.
