I make these every Christmas. They are a big hit with the kids. I believe the recipe came form Pillsbury originally, but you can use any sugar cookie dough.

INGREDIENTS
1 roll refrigerated sugar cookies
1/4 cup all-purpose flour
1 cup vanilla ready-to-spread frosting (or make your own)
64 small pretzel twists
64 semisweet chocolate chips (about 1/4 cup)
16 gumdrops, cut in half

DIRECTIONS
1. Heat oven to 350°F. In large bowl, break up cookie dough; work flour into dough until well blended. Shape roll of cookie dough into triangle-shaped log. (If dough is too soft to cut, place in freezer 30 minutes.)
2. With thin sharp knife, cut dough into 32 (1/4-inch-thick) triangular slices; place 2 inches apart on ungreased cookie sheet.
3. Bake 7 to 11 minutes or until set. Cool 1 minute; remove from cookie sheet to cooling rack. Cool completely, about 15 minutes.
4. Frost cookies with frosting. Place 2 pretzel twists on each triangle near corners for antlers. Lightly press 2 chocolate chips into each cookie for eyes and 1 halved gumdrop for nose. Store between sheets of waxed paper in tightly covered container.
