Preheat your oven to 425°F (220°C). Line a large baking sheet with aluminum foil and place a wire rack on top. Lightly grease the wire rack with cooking spray.
Pat the chicken wings dry thoroughly with paper towels to remove any moisture. This step is crucial for achieving crispiness.
In a large bowl, combine the baking powder, kosher salt, black pepper, garlic powder, and smoked paprika.
Add the chicken wings to the bowl and toss well to coat each wing evenly with the baking powder and seasoning mixture.
Arrange the wings in a single layer on the wire rack, making sure they are not touching to allow air circulation for crisping.
Bake the wings in the preheated oven for 25 minutes. Then, flip each wing over and continue baking for an additional 20 minutes or until the wings are golden brown and crispy.
Remove the wings from the oven and let them rest for 5 minutes before serving. This helps the skin stay crisp.
Serve the crispy baked chicken wings hot with your favorite dipping sauce.
