Heat oven to 350°F.
Sprinkle flour onto work surface; knead flour into cookie dough. With rolling pin, roll dough 1/4 inch thick. With cookie cutters or biscuit cutters, cut 12 (1 1/4-inch), 12 (1 1/2-inch) and 12 (2-inch) circles. To form each snowman, place 1 circle of each size, slightly overlapping, on ungreased cookie sheet.
Bake 7 to 9 minutes or until edges are light golden brown. Cool 1 minute; remove from cookie sheet to cooling racks. Cool completely, about 15 minutes.
Frost cookies with frosting; decorate with icing and candies.
