For top of cookie tart: Remove one piece of dough from refrigerator; place on center of cookie sheet. Using floured rolling pin, roll dough to 9-inch circle, 1/4 inch thick. Place 8-inch cake pan or bowl, top-side down, over dough, and lightly press into dough to mark an outline. Using small knife, cut around outline. Remove cake pan and any dough scraps from cookie sheet; set scraps aside. Bake 13 to 15 minutes or until cookie is light golden brown and edge is set. Immediately cut out star from center using 4-inch star cutter. Gently lift out cutout using small knife to help if needed; discard or save for another use. Cool on cookie sheet 10 minutes. Remove to cooling rack, leaving cookie on cooking parchment paper.
