In a mixing bowl, combine the softened 8 ounces cream cheese, 2 large eggs ¾ cup granulated erythritol, and 2 teaspoons vanilla extract Mix until smooth and well combined.
Gradually add the 2 cups almond flour, 5 tablespoon coconut flour, and 1 teaspoon baking powder to the cream cheese mixture. Stir until a dough forms. It should be firm enough to handle. If you are using ½ teaspoon cinnamon, and 1 teaspoon powdered erythritol, add them in now.
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.
Once done, remove the cookies from the air fryer and let them cool on a wire rack. They will firm up as they cool.
