Season the chicken wings with salt and pepper.
In a large bowl, combine flour, cornstarch, garlic powder, onion powder, paprika, and baking powder.
Dredge each wing in the flour mixture, shaking off excess.
In a large skillet or deep fryer, heat vegetable oil over medium-high heat.
Fry the chicken wings in batches for about 8-10 minutes or until golden brown and cooked through.
Remove and drain on paper towels.
In a separate saucepan, combine gochujang, honey, soy sauce, rice vinegar, sesame oil, garlic, and ginger.
Cook over medium heat for about 5 minutes, stirring until well combined and slightly thickened.
Toss the fried chicken wings in the sauce until evenly coated.
Serve hot, garnished with sesame seeds and chopped green onions.
