Preheat the oven: Preheat the oven to 400°F (200°C).
Prepare the chicken wings: Pat the chicken wings dry with paper towels. Drying the wings thoroughly is key to getting a crispy skin.
Make the seasoning mix: In a small bowl, combine baking powder, garlic powder, onion powder, paprika, salt, pepper, and cayenne pepper (optional).
Season the wings: Place the wings in a large bowl, drizzle with olive oil, and toss to coat evenly. Then sprinkle the seasoning mixture over the wings and toss again until fully coated.
Arrange the wings: Place the wings on a wire rack set over a baking sheet. This allows air to circulate around the wings, helping them cook evenly and get crispy.
Bake the wings: Bake the wings for 40-45 minutes, flipping them halfway through the cooking time. They should be golden brown and crispy. If you like extra crispy wings, you can bake them for an additional 5-10 minutes.
Optional – Toss in sauce: If desired, toss the wings in your favorite sauce (buffalo, BBQ, etc.) after baking.
