Heat oven to 375°F. Unwrap dough; on lightly floured surface, roll half of dough to 1/4-inch thickness. Cut with floured 5-inch Christmas tree-shaped cookie cutter. On ungreased cookie sheets, place cutouts 2 inches apart. Repeat with remaining half of dough. Bake 8 to 10 minutes or until edges are set. Cool 2 minutes; remove from cookie sheets to cooling racks. Cool completely, about 30 minutes.
