Absolutely! Just make sure that you roll them in the powdered sugar before freezing the dough for later. The powdered sugar won’t stick to the dough after it has been frozen. To keep the raw dough balls from sticking together in the freezer, first put the raw dough balls flat on a baking sheet (not touching each other) for at least 30 minutes. Once the dough balls are frozen, you can combine them in a sealable container and store the unbaked cookies in the freezer for up to 3 months.
