For an extra layer of flavor, consider adding a pinch of garlic powder or smoked paprika to the cracker crumb mixture. If you don't have an ice cream scoop, you can use a spoon to form the mac and cheese balls. Ensure the mac and cheese balls are thoroughly frozen before coating to prevent them from falling apart during the air frying process. Adjust air frying time based on your specific air fryer model. Keep a close eye on the balls to prevent burning.
