Preheat oven to 425ยบ F and line a baking sheet with aluminum foil. Place a wire rack inside the pan. Spray the rack with cooking spray.
Use paper towels to pat the wings dry, removing as much moisture as possible.
Place the wings in a large bowl and add the salt, black pepper, garlic powder and baking powder and toss to completely coat the wings.
Place the wings on the wire rack, skin side up, in a single layer.
Bake the wings in the oven for 30 minutes, then flip and cook an additional 20 - 30 minutes, until wings are cooked through and crispy.
