Chocolate Star Cookies

This easy-to-mix chocolate dough yields three batches of cookies, including these star-shaped cookies plus cookie sandwiches that can be filled with frosting or ice cream (see related recipes at left). Storage tip: The dough disks can be stored in the refrigerator for up to 3 days or in the freezer for up to 1 month. If freezing the disks, wrap in plastic wrap and then place in heavy-duty sealable plastic bags. Thaw overnight in the refrigerator before using.
