Pat the chicken wings thoroughly dry with paper towels to ensure maximum crispiness.
In a large bowl, toss the wings with baking powder, salt, and pepper until evenly coated.
Preheat the air fryer to 400°F (200°C).
Arrange the wings in a single layer in the air fryer basket, ensuring they do not overlap.
Air fry for 10 minutes, then flip the wings and cook for an additional 10 minutes until the skin is golden brown and crispy.
In a separate large bowl, whisk together the buffalo hot sauce, melted butter, and garlic powder.
Transfer the cooked wings to the sauce bowl and toss until thoroughly coated.
Serve immediately with celery sticks and dip.
