1Heat oven to 375°F. In medium bowl, stir together cookie mix, flour, melted butter and egg until soft dough forms. On floured surface, roll dough to 1/4-inch thickness. Cut with floured 4-inch reindeer-shaped cookie cutter. On ungreased cookie sheets, place cutouts 1 inch apart.
2Bake 7 to 9 minutes or until lightly browned. Cool 1 minute; remove from cookie sheets to cooling racks. Cool completely.
3In small bowl, mix white icing and food color. Spread over heads and bodies of reindeer. Frost antlers, tails and hooves with chocolate frosting. Decorate as desired with decorating gel. Let stand until set.
