Arrange frozen cookie dough balls on a small cookie sheet or baking pan. You can bake as many as you like, but leave approximately an inch between dough balls.
Place baking pan into air fryer basket, and air frozen cookie dough 8-15 minutes. The exact time will depend on how large your cookie dough balls are, and how crisp you like them.
Carefully remove the baking pan from the air fryer, leave cookies to cool on the pan for 2-3 minutes and then remove to a wire rack to cool completely.
