Preheat the air fryer to 400°F (200°C) for about 5 minutes.
In a large bowl, toss the chicken drumsticks with olive oil, salt, black pepper, garlic powder, onion powder, smoked paprika, and cayenne pepper. Ensure the drumsticks are evenly coated.
Place the seasoned drumsticks in the air fryer basket in a single layer, ensuring they are not crowded.
Air fry the drumsticks for 25-30 minutes, flipping them halfway through the cooking time to ensure even crispiness.
While the drumsticks are cooking, heat the barbecue sauce in a small saucepan over medium heat until warmed.
In the last 5 minutes of cooking, brush the drumsticks with a generous layer of barbecue sauce.
Check the drumsticks for doneness; they should have a golden and crispy exterior, and the internal temperature should reach 165°F (74°C).
Remove the drumsticks from the air fryer and let them rest for a few minutes.
Serve the Sky-High BBQ Bliss Drumsticks hot, garnished with chopped fresh herbs if desired.
