Place the cookies upside down on a large, parchment lined baking sheet so that the solid chocolate bottom is facing up.

Pour each set of candy melts into a shallow, microwave safe bowl and heat for 30 seconds in the microwave. Stir the melts well and continue to heat in 10-15 second increments, stirring well between each heating, until the melts are completely liquid and combined.

Dip each chocolate kiss bottom into the candy melts to coat the bottom and just a tiny bit of the side edge.

Allow any excess to drip off and then place the kiss on the center of a cookie, creating a witch’s hat.

Place one mini M&M, "m" side down, on the candy melt band and then repeat with the remaining ingredients.

Allow the witch hats time to set completely, about 15-30 minutes, before serving.
