In a mixing bowl, combine the softened cream cheese, egg, low-carb sweetener, and vanilla extract. Mix until smooth and well combined.
Gradually add the almond flour and baking powder to the cream cheese mixture. Stir until a dough forms. It should be firm enough to handle.
Divide the dough into small portions and roll them into balls. Place them on a plate or tray lined with parchment paper.
Place the cookie dough balls into the air fryer basket, leaving some space between each cookie to allow for expansion.
Air fry the cookies at 325°F (160°C) for 8-10 minutes or until they turn golden brown on the outside. The exact cooking time may vary slightly depending on your air fryer, so keep an eye on them.
Once done, remove the cookies from the air fryer and let them cool on a wire rack. They will firm up as they cool.
Enjoy your delicious Air Fryer Keto Cream Cheese Cookies as a low-carb treat or dessert!
