1. Preheat your oven to 400°F (200°C).
2. Pat the chicken wings dry with paper towels to remove excess moisture.
3. In a large bowl, combine baking powder, garlic powder, onion powder, smoked paprika, ground cumin, salt, black pepper, and cayenne pepper.
4. Add the chicken wings to the bowl and toss until they are evenly coated with the dry rub.
5. Place a wire rack on a baking sheet and arrange the wings in a single layer on the rack.
6. Bake for 40-45 minutes, or until the wings are golden brown and crispy.
7. Let them cool for 5 minutes before serving.
