You can also freeze the cookie dough if you want to get a head start on your baking. If you plan to freeze them don’t roll them in the sugar yet! Wait to do that just before baking. Arrange the dough balls on the baking sheet in a single layer and flash-freeze them until solid. Transfer the balls to a freezer bag and keep them frozen for up to 3 months. Take out whatever you need for baking, whether it’s all of them or just some! Bring them to room temperature, roll them in sugar, then bake as directed.
