Pat the chicken sausages completely dry with a paper towel and insert a wooden skewer into each link.
In a tall glass, whisk together the cornmeal, whole wheat flour, baking powder, sea salt, and garlic powder.
Add the egg whites and almond milk to the dry ingredients and stir until a thick, smooth batter forms.
Lightly coat the air fryer basket with avocado oil and preheat the unit to 375°F.
Dip each skewered sausage into the tall glass, rotating it to ensure an even, thick coating of batter.
Carefully place the coated sausages into the air fryer basket, ensuring they do not touch.
Air fry for 8-10 minutes, turning halfway through, until the batter is crisp and deeply bronzed.
Serve the corn dogs immediately with yellow mustard for a clean, high-protein dipping option.
