Pat Dry and Season: Pat the drumsticks very dry with paper towels — this is the most important step for crispy skin, so don't rush it. In a small bowl, whisk together the baking powder, garlic powder, smoked paprika, onion powder, salt, black pepper, and chili powder (if using). Rub the drumsticks with the olive oil, then sprinkle the seasoning mix evenly over all sides, rubbing it in with your hands.

Preheat the Air Fryer: Preheat your air fryer to 400°F (200°C) for 3–5 minutes. A hot start helps the skin start rendering and crisping immediately.

Air Fry Until Crispy: Place the drumsticks in the air fryer basket in a single layer with space between each piece — cook in batches if needed rather than crowding. Air fry at 400°F (200°C) for 20–25 minutes, flipping the drumsticks halfway through. They're done when the skin is deep golden and crispy and the internal temperature reaches 165°F (74°C) on an instant-read thermometer.

Rest Before Serving: Transfer the drumsticks to a plate and let them rest for 3–5 minutes. This lets the juices redistribute so every bite is juicy. Serve as-is for the classic crispy version, or continue to the glaze step.

Make the Sticky Glaze (Optional): While the drumsticks rest, melt the butter in a small saucepan over medium heat. Add the minced garlic and cook for 30 seconds until fragrant. Stir in the honey, soy sauce, and ketchup and simmer for 2–3 minutes until slightly thickened and glossy. Toss the crispy drumsticks in the glaze until fully coated.

Garnish and Serve: Sprinkle the glazed drumsticks with sesame seeds and sliced green onions. Serve hot with ranch, blue cheese, or your favorite dipping sauce.
