Preheat your air fryer to 360°F. Lightly spray the basket with avocado or olive oil cooking spray.
Pat the chicken breasts dry with a paper towel and place them in a bowl. Pour buffalo sauce over the chicken and season with salt, garlic powder, and pepper. Toss to coat evenly. Let marinate for 5 minutes.
Place the chicken in the air fryer basket in a single layer. Air fry for 10 minutes, then flip the chicken and cook for an additional 5 minutes or until the internal temperature reaches 165°F.
Remove the chicken from the air fryer. Brush with a little extra buffalo sauce if desired and let rest for 5 minutes before serving. Serve with carrots, celery sticks, and blue cheese if desired.
