Pat the chicken wings completely dry with paper towels to ensure maximum crispiness.
In a large bowl, toss the wings with baking powder, sea salt, black pepper, and garlic powder until evenly coated.
Place the wings in a single layer in the air fryer basket and cook at 400 degrees Fahrenheit for 20 minutes, flipping halfway through.
While wings cook, whisk together honey, coconut aminos, minced garlic, grated ginger, and sesame oil in a small saucepan over medium heat.
Simmer the sauce for 3 to 5 minutes until it thickens into a glossy glaze.
Transfer the crispy wings to a clean bowl, pour the warm honey-garlic glaze over them, and toss to coat thoroughly.
Garnish with sliced green onions and serve immediately alongside fresh cucumber slices for a cooling crunch.
