These cookies are 1000% best fresh. But if you need to, you can make the dough, form it into a disc, and freeze it wrapped in plastic for up to 3 months. Then just thaw it and proceed with the recipe as written. Another option is to make, roll, and cut the dough into circles. Then freeze the circles flat on a cookie sheet, store in a zipper bag, and freeze for up to 3 months. You can bake them straight from frozen, just add 1-2 minutes of baking time.
