Make Ahead: Cookie dough can be made ahead and stored covered tightly in the fridge for up to 3 days.
Storage: Store baked cookies covered at room temperature for up to a week.
Freezer Instructions: Baked cookies can be stored in a freezer bag in the freezer for up to 3 months. To freeze unbaked cookies, roll dough into balls, but don't roll in powdered sugar.

No need to thaw.
