Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper, placing a wire rack on top.
Pat the chicken wings extremely dry with paper towels to ensure the skin gets maximum crispiness.
In a large bowl, toss the wings with baking powder, sea salt, and black pepper until evenly coated.
Arrange wings on the wire rack in a single layer and bake for 40-45 minutes, flipping halfway through.
While wings bake, whisk honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium heat.
Mix arrowroot starch with water to create a slurry, then whisk into the sauce and simmer until thickened and glossy.
Remove crispy wings from the oven and immediately toss them in a large bowl with the warm honey-garlic glaze.
Garnish with sliced green onions and sesame seeds before serving hot.
