Place dark chocolate and butter in a medium microwave-safe bowl; melt by microwaving in 30-second increments and stirring vigorously in-between; continue until melted and smooth; stir in peppermint extract
Use two forks to dip cookies into melted chocolate; immediately sprinkle with peppermint baking pieces
Chill in refrigerator for one hour or until ready to serve or package; best kept in a cool dry place but will stay nice longer in refrigerator
