Heat oven to 350°F. In small bowl, mix granulated sugar and cinnamon. Unwrap dough. On lightly floured surface, roll each portion to 1/4-inch thickness. Cut with floured 2 1/2-inch round cookie cutter. On ungreased cookie sheets, place rounds 1 inch apart. If desired, reroll scraps for additional cutouts. Sprinkle with cinnamon-sugar. Bake 11 to 13 minutes or until edges are set. Cool 1 minute; remove from cookie sheets to cooling racks. Cool completely, about 30 minutes.
