01 - Preheat oven to 425°F. Line a baking sheet with foil and place a wire rack on top.
02 - Pat chicken wings completely dry with paper towels. In a large bowl, toss wings with baking powder, salt, and black pepper until evenly coated.
03 - Arrange wings in a single layer on the wire rack. Bake for 20 minutes, then flip and bake another 20 minutes until crisp and golden brown.
04 - In a small saucepan over low heat, melt the butter. Add hot sauce, vinegar, garlic powder, Worcestershire sauce, and cayenne (if using). Whisk to combine and heat until just simmering. Remove from heat.
05 - Transfer baked wings to a large bowl. Pour Buffalo sauce over wings and toss to coat evenly.
06 - Serve immediately with celery, carrot sticks, and blue cheese or ranch dressing on the side.
