Turn on your air fryer to 375F and allow it to preheat
Place the cornmeal, eggs, buttermilk, sugar, salt, and baking powder in a tall glass and mix until smooth.
Starting from one end, push the skewer into the middle of the hot dog lengthwise 3/4 of the way.
Roll the skewered hot dog in a shallow dish of flour until well coated.
While holding the skewer, carefully dip the flour coated hot dog into the tall glass of batter.
Add the battered corn dogs to the preheated air fryer basket, leaving plenty of room between them.
Cover the corn dogs with a light layer of cooking spray to help them crisp.
Air fry for 8 minutes, flipping half way through and coating the other side with cooking oil.
Tips and Tricks
For a thicker batter, you dip the corn dogs, freeze them for 20-30 minutes, and then dip a second time before cooking.
No bamboo skewers? Make air fryer corn dog nuggets. Cut the hotdogs into 2 or 3 pieces and dip. Use a fork to transfer from the batter to the air fryer basket.
Give them space. Just like with any other air fryer recipe, layering will not allow the food to cook evenly. Make sure you leave around 1/2" to 1" of space between each corndog for adequate air flow.
