Preheat your air fryer to 400°F (200°C) and spray the basket with nonstick cooking spray.

Set up three bowls: one with flour, cornstarch, and salt; the second with whisked eggs; and the third with panko breading.

Coat each chicken piece in the flour mixture, egg wash, and then panko breading, pressing lightly for adherence.

Arrange breaded chicken pieces in a single layer in the air fryer basket.

Cook at 400°F (200°C) for 8 minutes, flipping halfway through for even browning.

Toss the cooked bites with buffalo sauce in a large bowl.

For extra crispiness, return bites to the air fryer for an additional 3-4 minutes.

Allow to cool slightly before serving with ranch or blue cheese dressing.
