Add a large dollop of chocolate frosting to a chocolate wafer.

Press 2 mini pretzel twists onto the top to create antlers.

Add another wafer cookie on top and press gently to make a sandwich cookie.

Add a small amount of frosting to the Nilla Wafer and add to the front to make a face.

Place a small amount of frosting onto the back of 2 candy eyes and add it to the face, above the Nilla wafer.

Add a candy nose and attach by putting a small amount of frosting on the back of a mini M&M candy.

Repeat until you have the desired number of cookies.
