Preheat your oven to 425°F and line a baking sheet with parchment paper, placing a wire cooling rack on top.
Pat the chicken wings thoroughly dry with paper towels to ensure the skin becomes extra crispy during baking.
In a large bowl, toss the wings with baking powder, sea salt, and black pepper until every wing is evenly coated.
Arrange the wings in a single layer on the wire rack and bake for 35-40 minutes, flipping halfway through, until golden brown.
While the wings bake, combine honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium heat.
Whisk the arrowroot starch with a teaspoon of water to create a slurry, then stir it into the sauce and simmer until thickened.
Remove the crispy wings from the oven and immediately toss them in a bowl with the warm honey-garlic glaze.
Garnish with thinly sliced green onions and serve while hot.
