01 - Preheat oven to 425°F. Line a baking sheet with parchment paper and set a wire rack on top.
02 - In a large bowl, toss chicken wings with baking powder, kosher salt, and black pepper until evenly coated.
03 - Arrange seasoned wings in a single layer on the prepared rack. Bake for 35 to 40 minutes, flipping once halfway through, until skin is crisp and golden.
04 - While wings bake, blend black garlic, soy sauce or tamari, honey, balsamic vinegar, toasted sesame oil, unsalted butter, activated charcoal powder, ground ginger, and cayenne pepper until smooth.
05 - Pour glaze mixture into a small saucepan and heat over medium-low until it begins to bubble and thickens slightly, about 2 to 3 minutes. Remove from heat.
06 - Transfer cooked wings to a large bowl. Pour warm glaze over the wings and gently toss to evenly coat, ensuring a glossy finish.
07 - Arrange glazed wings on a platter. Sprinkle with toasted sesame seeds and sliced scallions if desired. Serve immediately.
