Line a baking sheet or tray with parchment paper so the cookies don’t stick while setting.

Gently snap each pretzel in half to create antlers. Set aside.

Place the melting wafers in a microwave-safe bowl. Heat in 30-second intervals, stirring after each round, until the chocolate is smooth and fully melted.

Dip one Oreo into the melted chocolate, turning it to coat completely. Lift it out with a fork, let the excess chocolate drip off, and place it on the prepared tray.

While the chocolate is still wet, press two pretzel halves at the top of the cookie to form antlers.

Add two candy eyes just under the pretzels, then press a red M&M into the center for the nose.

Repeat with the remaining cookies. Let the reindeer cookies sit at room temperature for about an hour, or until the chocolate sets.
