Pat the chicken wings dry with paper towels so the coating sticks well.
In a big bowl, mix together the flour, cornstarch, salt, black pepper, and garlic powder.
Toss the wings in the flour mixture until they’re fully coated, then shake off the excess.
Heat oil in a Dutch oven or deep skillet over medium-high until it hits 350°F.
Fry the wings in batches for about 8-10 minutes until golden and crispy.
Set them on a wire rack or paper towels.
In a small saucepan, stir together the gochujang, soy sauce, honey, brown sugar, rice vinegar, sesame oil, garlic, and ginger.
Simmer for 2-3 minutes on low heat until it thickens a bit.
Toss the crispy wings in the warm sauce until coated.
Sprinkle on sesame seeds and green onions right before serving.
