Preheat the air fryer to 400°F (200°C) for 5 minutes.
In a large bowl, combine garlic powder, smoked paprika, onion powder, salt, black pepper, cayenne pepper, and baking powder.
Pat the chicken wings dry with paper towels to remove excess moisture.
Add the chicken wings to the bowl with the seasoning mixture and toss until all wings are evenly coated.
Lightly spray the air fryer basket with cooking spray to prevent sticking.
Arrange the wings in a single layer in the air fryer basket, making sure they are not overcrowded. You may need to cook in batches.
Cook the wings at 400°F (200°C) for 12 minutes.
After 12 minutes, flip the wings and cook for an additional 12 minutes or until the wings are crispy and cooked through (internal temperature should reach 165°F or 74°C).
If desired, spray the wings lightly with cooking spray and cook for an additional 1-2 minutes to increase crispiness.
Remove the wings from the air fryer and let them rest for 2 minutes before serving.
