Pat the chicken wings completely dry with paper towels, then toss with avocado oil, baking powder, garlic powder, smoked paprika, black pepper, and salt until evenly coated.
Arrange the wings in a single layer on a wire rack set over a baking sheet, leaving space between each piece.
Bake at 425°F / 220°C for 45 minutes, flipping halfway through, until the skin is golden brown and crispy and the internal temperature reaches 165°F / 74°C at the thickest part.
Rest the wings on the wire rack for 5 minutes to let the skin set and stay crisp.
Serve plain or toss with your favorite sauce such as buffalo, barbecue, or honey garlic.
