Pat the chicken with a towel until it is dry.
In a bowl, add the chicken, ½ cup of the buffalo sauce, olive oil, garlic powder, and onion powder. Toss well to combine and evenly coat the chicken.
Let the chicken marinate for at least 20 minutes.
Preheat the air fryer to 400 degrees F.
Add the chicken and cook for 10 minutes.
Flip and cook another 8-10 minutes, until the chicken is cooked through to an internal temperature of 165 degrees F.
In a small bowl, combine the remaining ¼ cup of buffalo sauce and melted butter.
Brush over the cooked chicken. Serve and enjoy!
