Place the chicken wings in a large bowl and toss with the flour, cornstarch, baking powder and seasonings. Make sure they are well coated then place them in the air fryer basket.
Air fry the chicken wings for 20-25 minutes until they are golden and crispy. Shake the basket or turn the wings half way through to ensure even cooking.
Place the cooked chicken wings in a large bowl, add the butter, parmesan, garlic and herbs and toss until well coated.
