Whip egg, salt, and pepper in a shallow bowl until well combined. Mix cornbread crumbs, panko, honey powder, and poultry rub in a separate shallow bowl.
Dip each chicken tender in the egg mixture. Shake off excess and dredge in cornbread coating.
Preheat an air fryer to 380 degrees F (190 degrees C). Cook chicken tenders for 6 minutes. Flip and cook for an additional 6 minutes.
