Heat oven to 375°F. Onto ungreased cookie sheets, drop dough by 2 tablespoonfuls per cookie about 2 inches apart (refrigerate any remaining dough until ready to use). Bake 10 to 12 minutes or until puffed and dry on tops (centers will be very soft). Cool 2 minutes; remove from cookie sheets to cooling racks. Cool completely before storing in airtight container, using waxed paper between cookie layers.
