Prep the wings: Pat the wings very dry with paper towels. In a large bowl, toss with baking powder, salt, pepper, smoked paprika, garlic powder, and cayenne if using. Coat evenly.
Oven method: Heat oven to 425°F (220°C).
Place wings on a wire rack set over a foil-lined baking sheet. Bake for 40–45 minutes, flipping halfway, until golden and crispy.
Air fryer method: Heat to 390°F (200°C). Arrange wings in a single layer.
Air fry 22–26 minutes, shaking the basket or flipping halfway, until crisp and cooked through.
Make the sauce: In a small skillet, melt butter with olive oil over medium-low heat. Add minced garlic and cook 60–90 seconds until fragrant but not browned. Stir in hot sauce, red pepper flakes, lemon juice, and half the Parmesan.
Remove from heat.
Toss to coat: Transfer hot wings to a large bowl. Pour the warm sauce over and toss to coat. Add remaining Parmesan and toss again for a thick, clingy finish.
Garnish and serve: Sprinkle with extra Parmesan and parsley.
Serve immediately with lemon wedges if you like a bright finish.
