Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C) for 5 minutes.
Prepare the Wings: Pat the chicken wings dry with paper towels to remove any excess moisture. This will help them crisp up better in the air fryer.
Season the Wings: In a large bowl, mix the olive oil, garlic powder, onion powder, paprika, salt, pepper, and cayenne pepper (if using). Add the wings and toss them in the spice mixture until they are evenly coated.
Air Fry the Wings: Arrange the wings in a single layer in the air fryer basket. Cook at 375°F (190°C) for 20-25 minutes, flipping halfway through, until the wings are golden brown and crispy. You may need to do this in batches depending on the size of your air fryer.
Prepare the Buffalo Sauce: While the wings are cooking, melt the butter in a small saucepan over medium heat. Once melted, add the buffalo hot sauce and vinegar, stirring until combined and heated through.
Toss the Wings in Sauce: Once the wings are done, transfer them to a large bowl and pour the buffalo sauce over them. Toss the wings until they are evenly coated in the sauce.
Serve: Serve the buffalo chicken wings hot with celery sticks and your favorite dipping sauce, such as blue cheese or ranch dressing.
