Preheat oven to 375°F. Line baking sheet with parchment paper.

In a mixing bowl, add cookie mix, cocoa powder, softened butter and egg.

Using a hand mixer, combine the ingredients until a soft dough is formed.

Roll into a ball and chill for 30 minutes.

Sprinkle a little cocoa powder on your work surface. Place dough on top of the cocoa powder. Dust the rolling pin with the cocoa powder.

Roll the dough out to ¼ inch thick.

Cut out cookies with a round cookie cutter. Carefully stretch the cookie rounds to make them a slightly oval shape. Place them on the baking sheets.

Add two pretzels under the top of the cookie for the antlers.

Gently press two blue M&Ms into the dough for the eyes and one red M&M for the nose on each cookie.

Bake for 8 minutes. Remove from oven and allow to cool. Repeat until all the cookies have been baked.
