Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper, placing a wire cooling rack on top.
Pat the chicken wings thoroughly dry with paper towels; removing moisture is the essential secret to achieving a deep crunch without deep-frying.
In a large mixing bowl, toss the wings with the baking powder, sea salt, and black pepper until every wing is evenly coated.
Arrange the wings on the wire rack in a single layer, ensuring they are not touching, and bake for 45-50 minutes, flipping halfway through until golden brown.
While the wings bake, combine the honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium-low heat.
Simmer the sauce gently for 3-5 minutes, whisking occasionally, until it reduces into a thick, glossy, and fragrant glaze.
Transfer the hot, crispy wings into a clean bowl, pour the warm honey-garlic glaze over them, and toss immediately to coat.
Garnish with thinly sliced green onions and serve immediately while the skin is at its peak crispness.
