Make Hot Honey Sauce: In a large bowl, combine honey, hot sauce, apple cider vinegar, garlic powder, Kosher salt, onion powder, smoked paprika, and pepper. Stir well. Spoon half of the sauce into a separate small bowl, and set that small bowl aside.
Prepare Chicken: Blot all sides of chicken thighs dry with paper towels.
Marinate: Add chicken to large bowl of marinade, cover with plastic wrap or foil, and marinate for 15-30 minutes in the refrigerator. (You can marinate the chicken for as little as 15 minutes or as long as 24 hours.)
Preheat Grill: While chicken marinates, turn on grill and set it to medium-high heat (around 375 degrees F to 450 degrees F).
Oil Grates: Brush grill grates with olive oil to prevent chicken from sticking.
Grill Then Glaze Chicken: Place chicken thighs on grill. Cook with grill lid closed for about 4-7 minutes on each side, or until internal temperature reaches 165 degrees F. During last few minutes of grilling, brush chicken with hot honey sauce from small bowl you had set aside, flipping chicken over to coat both sides.
Rest Chicken Then Serve: After cooking, transfer chicken to a plate and let it rest for a few minutes, then serve.
