Preheat your oven to 400°F and line a large baking sheet with parchment paper, placing a wire cooling rack on top.
Pat the chicken wings completely dry with paper towels to ensure the skin gets maximum crispiness in the oven.
In a large mixing bowl, toss the wings with the baking powder, avocado oil, sea salt, and black pepper until evenly coated.
Arrange the wings in a single layer on the wire rack and bake for 35 to 40 minutes, flipping halfway through, until golden brown.
While the wings are roasting, combine the honey, tamari, minced garlic, and grated ginger in a small saucepan over medium-low heat.
Simmer the sauce for 5 minutes, stirring occasionally, until it reduces into a thick and glossy glaze.
Remove the crispy wings from the oven and immediately transfer them to a clean bowl, pouring the warm glaze over them.
Toss the wings until thoroughly coated, then garnish with sesame seeds and thinly sliced green onions before serving.
