Add the egg, milk, and spices. Mix until combined. Let batter sit in the refrigerator for 30 minutes.
Roll the batter into balls (about the size of ping pong balls), and line the air fryer basket with parchment paper. Spray the paper with oil, and place the hush puppy balls in the basket. Spray the balls with oil.
Cook at 380 degrees in the air fryer (lined with parchment paper) for five minutes, turn balls, spray with oil, and cook for five more minutes.
If you want to make these hush puppies gluten-free, just swap out the flour for gluten-free flour. You'll want to check that your cornmeal is gluten-free too.
To make these dairy-free, use almond or cashew milk in place of the dairy milk in the recipe.
