Preheat air fryer to 375°F and lightly grease the basket with avocado oil.
Pat the chicken sausages dry with a paper towel and insert a wooden skewer into each link.
In a shallow dish, whisk together the cornmeal, almond flour, baking powder, sea salt, and garlic powder.
In a separate small bowl, beat the egg with the almond milk until well combined.
Pour the wet ingredients into the dry ingredients and stir until a thick, smooth batter forms.
Transfer the batter into a tall glass to make dipping the sausages easier.
Dip each skewered sausage into the batter, rotating to coat completely and letting any excess drip off.
Place the corn dogs in the air fryer basket, ensuring they do not touch each other.
Air fry for 10 minutes, turning halfway through, until the coating is firm and beautifully browned.
