Freeze the raw cookies on the baking sheet. Once the cookies are frozen, transfer to an airtight container. They will keep for 3 months in the freezer. You can bake them from frozen for about 12 minutes.
The power of air fryers varies greatly from one brand to another. Therefore, the cooking time may also vary. If your air fryer basket is not big enough to cook 4 cookies at a time, you may need to bake the cookies for less time.
