IF TIME PERMITS: pat wings dry with a paper towel. Combine the baking powder, salt, pepper, and garlic powder, in a bowl. Season wings evenly all over. Place a wire rack on a baking sheet. Spread the wings out on the rack. Place in the refrigerator, uncovered, on the bottom shelf overnight for best results or at least 45 minutes, if possible.
REMOVE: Make sure to remove them from the fridge 30-40 minutes before baking.
PREP: Position a rack in the upper third of the oven. Preheat the oven to 475ºF. Line a baking sheet with foil, then place a wire rack on top of the baking sheet. Spray the wire rack with cooking spray to keep the wings from sticking to it. Place the wings skin side up on the wire rack.
BAKE: Bake the wings for 28-38 minutes, depending on the size of the wings, flipping them after the first 18 minutes until they’re golden and cooked through. See notes for air fryer directions.
SAUCE: In a saucepan, melt the butter over medium heat. Add the garlic and saute it for 45-60 seconds or until fragrant. Add the Gochujang paste, toasted sesame oil, honey, soy sauce, and rice vinegar and whisk to combine. Once the sauce gains a simmer, turn the stove off.
TOSS: Pour the sauce into a large metal bowl, add the wings and toss to coat.
OPTIONAL: You can place the wings under the broiler if you want to give them a bit more color for a few seconds, I typically do. Then top with sesame seeds, green onions, and serve.
