Preheat oven to 425°F (220°C). Line a baking sheet with foil or parchment. Set a wire rack on top and spray the rack lightly with cooking spray.
Pat the wings very dry with paper towels (this is key for crispy skin).
In a large bowl, toss wings with baking powder, salt, pepper, garlic powder, and paprika until evenly coated.
Arrange wings in a single layer on the rack, leaving a little space between pieces (don’t let them touch).
Bake 45–50 minutes, flipping halfway through, until golden and crisp. Wings are done when they reach 165°F (74°C) in the thickest part.
While wings bake, whisk together hot sauce, melted butter, vinegar, Worcestershire, and garlic powder in a small bowl until smooth.
When wings are done, let them rest 2–5 minutes. Transfer to a clean bowl, pour sauce over, and toss until fully coated.
Optional: For extra crunch, return sauced wings to the oven for 3–5 minutes. Serve immediately with ranch or blue cheese and celery sticks.
