01 - Preheat oven to 425°F. Line a baking sheet with parchment paper and position a wire rack on top.
02 - Pat chicken wings thoroughly dry using paper towels. In a large mixing bowl, combine the wings with baking powder, salt, and black pepper. Toss to evenly coat.
03 - Arrange wings in a single layer on the prepared rack. Bake for 35 to 40 minutes, turning wings over halfway through, until golden and crispy.
04 - While wings are baking, mix melted butter, lemon juice, lemon zest, black pepper, garlic powder, onion powder, and salt in a large bowl until combined.
05 - Transfer hot baked wings directly into the bowl with the lemon pepper sauce. Toss thoroughly to coat each wing.
06 - Arrange wings on a platter and serve immediately with extra lemon wedges if desired.
