Unroll pie crusts on work surface. With 2 1/2-inch scalloped round cutter, cut 15 rounds from 1 crust and 9 from the other. Fit rounds into muffin cups, pressing in gently. Generously prick crusts with fork. From remaining crust, cut 24 1-inch star shapes; place on ungreased cookie sheet. Sprinkle with coarse sugar. Bake crusts 6 to 9 minutes or until light golden brown. Cool crusts completely on cooling rack, about 15 minutes; remove from muffin cups. Meanwhile, bake star shapes 3 to 4 minutes or until light golden brown.
