01 - Preheat oven to 450°F. Line a large baking sheet with parchment paper or foil and set a wire rack on top. Lightly grease the rack.
02 - Pat the chicken wings completely dry with paper towels to ensure maximum crispiness.
03 - In a large bowl, toss wings with baking powder, salt, pepper, garlic powder, and smoked paprika until evenly coated.
04 - Arrange the wings in a single layer on the prepared rack, spacing them apart to allow air circulation.
05 - Bake for 25 minutes until the skin begins to crisp and brown.
06 - Flip the wings and continue baking for another 20 minutes, or until golden brown and crispy throughout.
07 - While wings bake, melt butter in a small saucepan over medium-low heat. Add minced garlic and cook for 1–2 minutes until fragrant but not browned.
08 - Remove from heat. Stir in Parmesan, parsley, chili flakes if using, and season with salt and pepper.
09 - Transfer crispy wings to a large bowl. Pour the garlic parmesan sauce over and toss to coat evenly. Serve immediately, garnished with extra Parmesan and parsley if desired.
