Pat the chicken wings dry with paper towels. The drier the skin, the crispier they’ll get, so a quick pat-down helps.
In a large bowl, combine the baking powder, paprika, garlic powder, onion powder, salt, pepper, and cayenne. Stir to create a quick rub.
Add the wings to the bowl and toss with the rub until evenly coated. Drizzle with olive oil and toss again so every piece has a light coating.
Preheat your air fryer to 400°F (200°C) if your model requires preheating.
Arrange the wings in a single layer in the air fryer basket. You may need to work in batches to prevent overcrowding.
Air fry for 20–25 minutes, turning halfway through, until the skin is crisp and the wings reach an internal temperature of at least 165°F (74°C).
Let the wings rest for a couple of minutes before serving. A quick squeeze of lemon or a sprinkle of extra salt can be nice if you like.
