Melt chocolate in a double boiler over simmering water, or in the microwave, stirring every 30 seconds until completely melted.

Roll and dip each Oreo cookie into the melted chocolate, remove with a fork, then place on parchment paper or a baking rack to cool.

Sprinkle with crushed peppermint candies while still warm.

Let cool for about 30 minutes. You can speed up the cooling by placing the cookies in the refrigerator.
