Pat the chicken breast pieces very dry with paper towels. Removing excess moisture is the most important step for getting a truly crispy coating in the air fryer.
In a shallow dish, whisk together the flour, cornstarch, garlic powder, smoked paprika, salt, and black pepper. In a separate bowl, beat the eggs.
Dip each chicken piece into the beaten eggs, let the excess drip off, then toss it in the seasoned flour mixture, pressing to coat well. For extra crunch, dip each piece back into the egg and then into the flour mixture a second time. Preheat the air fryer to 400 degrees F. Arrange the coated chicken pieces in a single layer in the basket, leaving space between each piece so the hot air can circulate. Spray the tops generously with cooking spray.
Air fry for 5 minutes, then flip each piece and spray again lightly with cooking spray. Cook for another 5 to 6 minutes until the coating is crispy and golden and the chicken reaches an internal temperature of 165 degrees F.
While the chicken cooks, prepare the buffalo sauce. In a large bowl, whisk together the hot sauce, melted butter, honey, and garlic powder until smooth and combined.
As soon as the boneless wings come out of the air fryer, transfer them directly into the bowl with the buffalo sauce. Toss gently until every piece is evenly coated.
Serve the boneless wings immediately with celery sticks, carrot sticks, and ranch or blue cheese dressing on the side.
