Dip each Oreo cookie in the melted chocolate and coat both sides. Remove the cookie from the chocolate with a fork.

Lightly tap the fork on the side of the bowl to remove excess chocolate and transfer the coated cookie to a piece of parchment or wax paper.

Immediately press two candy eyes into the center of the cookie and one red M&M into the bottom.

Dip the bottoms of two mini pretzels in the chocolate and place one pretzel on each side of the cookie to form antlers.

Do not disturb the cookies after the pretzels are put in place. Allow the chocolate to fully harden before moving the cookies to keep the antlers from falling off.

After all the cookies are decorated, allow them to sit at room temperature for one hour or in the refrigerator for 30 minutes, until the chocolate has hardened.
