Preheat the air fryer to 400 degrees F for 5 minutes, if needed.
Place the drumsticks in a large bowl and toss with avocado oil.
8 chicken drumsticks, 1 tbsp avocado oil
Combine baking powder and the spices in a separate bowl.
1 tbsp baking powder, 1 tsp paprika, 1 tsp onion powder, 1 tsp garlic powder, 3/4 tsp sea salt, 1/2 tsp ground black pepper
Sprinkle the chicken with the spice mixture and toss together until evenly coated.
Cook in the air fryer in a single layer for 20 minutes, flipping halfway through.
The internal temperature of the drumsticks should have reached 165 degrees F. If not, cook for longer until they do.
