Preheat the Air Fryer. Preheat your air fryer to 350°F.
Mix Ingredients. In a large mixing bowl, combine the ground sausage, biscuit baking mix, shredded cheddar cheese, garlic powder, onion powder, and black pepper. Mix until well combined.
Form Balls. Using your hands, shape the mixture into small balls, about 1 inch in diameter, and place them on a plate or tray.
Add To Basket. Lightly grease the air fryer basket with cooking spray. Arrange them in a single layer in the air fryer basket, making sure they are not touching each other.
Air Fry. Cook the sausage in the preheated air fryer for 10-12 minutes, or until golden brown and cooked through, flipping halfway through the cooking time for even browning.
Serve. Once cooked, remove them from the air fryer and transfer them to a serving platter. Serve warm with your favorite dipping sauce.
