Preheat the air fryer to 400°F (air fryer mode).
Pat the chicken wings completely dry with paper towels and place them in a large bowl.
Drizzle the olive oil over the wings and toss to coat evenly.
In a small bowl, whisk together the brown sugar, baking powder, garlic powder, onion powder, smoked paprika, chili powder, salt, and pepper until combined.
Add the spice mixture to the wings and toss until all pieces are evenly coated.
Lightly spray the air fryer basket with cooking spray. Arrange wings in a single layer without overcrowding, working in batches if needed.
Cook the wings for 7 minutes, flip each wing, then continue cooking for an additional 6–8 minutes until golden and crispy and an instant-read thermometer inserted into the thickest part reads 165°F.
Transfer wings to a platter and serve plain, with a dipping sauce, or toss in your preferred sauce such as buffalo or BBQ with sriracha to taste.
