Preheat the oven to 350 degrees. Line a baking sheet with foil or parchment for easier cleanup.
Make the sauce by stirring the hoisin sauce, soy sauce, honey, toasted sesame oil, vegetable oil, minced garlic, and cayenne. Set aside to allow flavors time to mingle.
Season and cook the wings by seasoning the wings with sea salt, freshly cracked pepper, and garlic powder to taste, then place them on a baking sheet in a single layer, skin side up.
Place into the oven and roast for 30 minutes.
Flip the wings over and cook for 10 minutes.
Sauce the wings by removing them from the oven and adding them to a large bowl. Drizzle the sauce on top and toss to coat the wings evenly with the sauce.
Return the sauced wings to the baking sheet and into the oven for 5 minutes.
Serve chicken wings topped with toasted sesame seeds and green onions. Enjoy.
