Preheat oven to 200c and place a wire rack over a baking sheet. In a large bowl, toss chicken wings with oil and season with garlic powder, salt, and pepper. Transfer to prepared baking sheet.
Bake until chicken is golden and skin is crispy, 50 to 60 minutes, flipping the wings halfway through.
In a small saucepan, whisk together hot sauce and honey. Bring to simmer then stir in butter. Cook until butter is melted and slightly reduced, about 2 minutes. Heat grill on low. Transfer baked wings to a bowl and toss with buffalo sauce until completely coated. Return wings to rack and grill until sauce caramelises, around 3 minutes - watch the wings carefully at stage!
