01 - Preheat your oven to 425°F. Line a large baking sheet with aluminum foil and place a wire rack on top. Lightly oil the wire rack to prevent adherence.
02 - Thoroughly pat the chicken wings very dry with paper towels; this step is paramount for achieving optimal crispiness.
03 - In a sizable mixing bowl, combine the baking powder, kosher salt, garlic powder, smoked paprika, black pepper, onion powder, and the optional cayenne pepper.
04 - Add the prepared chicken wings to the bowl with the seasoning mixture. Toss diligently to ensure each wing is uniformly coated.
05 - Arrange the seasoned wings in a single layer on the prepared wire rack. Ensure adequate spacing between wings to facilitate even air circulation and crisping.
06 - Bake the wings for 20 minutes. After this initial period, carefully flip each wing to expose the other side.
07 - Continue baking for an additional 25–30 minutes, or until the wings are deeply golden brown and exceptionally crispy.
08 - While the wings are baking, if opting for a sauce, whisk together the melted butter and hot sauce in a large bowl until well combined.
09 - Remove the crispy wings from the oven. If desired, immediately transfer them to the bowl with the prepared sauce and toss to coat thoroughly before serving. Alternatively, serve the sauce on the side.
