Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper, placing a wire cooling rack on top.
Pat the chicken wings thoroughly dry with paper towels to ensure maximum crispiness.
In a large bowl, toss the wings with the baking powder, sea salt, black pepper, and garlic powder until evenly coated.
Arrange the wings in a single layer on the wire rack, ensuring they are not touching.
Bake for 35 to 40 minutes, flipping halfway through, until the skin is golden brown and very crispy.
In a clean bowl, whisk together the olive oil, grated parmesan cheese, and dried parsley.
Add the hot wings to the bowl and toss gently until every wing is coated in the garlic parmesan mixture.
Serve immediately while hot and crunchy.
