In a large bowl, whisk together the buttermilk and hot sauce.
Add the chicken, making sure it’s fully submerged.
Cover and refrigerate for at least 2 hours (overnight is even better).
In another bowl, mix the flour, cornstarch, paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper.
Remove the chicken from the buttermilk, letting the excess drip off.
Coat each piece in the flour mixture, pressing gently to ensure the breading sticks.
Place the breaded chicken on a wire rack and let it sit for 10 minutes—this helps the coating adhere.
Preheat your air fryer to 375°F (190°C) for 5 minutes.
Lightly spray the air fryer basket with cooking spray.
Place the chicken pieces in a single layer, leaving space between them.
Lightly spray the chicken with cooking spray—this helps create crispiness.
Air fry at 375°F (190°C) for 25-30 minutes, flipping halfway through.
Use a meat thermometer to check that the internal temperature reaches 165°F (74°C).
Let the chicken rest for a few minutes before serving.
Serve hot with your favorite dipping sauces and sides.
