Line a baking sheet with wax paper or parchment paper.
Melt chocolate in a microwave-safe bowl in 30-second increments, mixing in between each increment until chocolate is smooth.
Break pretzels into antler shapes.
Dip the top third of a wafer cookie in the melted chocolate. Use a spoon to smooth off excess chocolate.
Lay cookies on a prepared baking sheet.
Add a red nose, two eyes and two antlers. If antlers fall off, wait for chocolate to set slightly before adding or dipping ends of pretzels in chocolate and then add to the cookie.
