Use a sharp knife to cut along the bone of each drumstick and press the meat flat. This helps them cook faster and more evenly. Pat dry with paper towels.

Rub the chicken with olive oil. In a small bowl, mix the salt, pepper, garlic powder, onion powder, paprika, and chili powder. Sprinkle the mix on both sides of each drumstick.

Preheat your grill to high heat (around 450°F). Place the chicken directly over the heat. Grill for about 4–5 minutes per side until nice and charred.

After charring, move the drumsticks to the cooler side of the grill. Lower the heat to around 275–300°F and cover. Add wood chunks if using a smoker. Cook for another 30–40 minutes, until internal temp reaches 175–180°F.

In a bowl, mix mayo, sweet chili sauce, hot sauce, garlic, red pepper flakes, lemon zest, lemon juice, and honey. Stir until smooth and creamy. Set aside.

Once chicken is done, brush or toss the drumsticks with bang bang sauce. Garnish with chives or more pepper flakes. Serve right away.
