In a large bowl, mix together the ingredients for the marinade. Toss the wings in the marinade and coat thoroughly. Set aside in the refrigerator and let marinate for about an hour.
Preheat the oven to 375°F. Line a baking sheet with parchment paper or aluminum foil. Distribute the wings in one layer on the baking sheet. Bake for 45-50 minutes or until wings are browned and cooked through.
While the wings are baking, mix together the ingredients for the sauce in a small bowl. Taste and adjust seasonings. Store-bought gochujang tends to be on the sweeter side so I would add the brown sugar as needed.
Turn broiler on high.
Liberally brush the wings with the sauce mixture. Broil 3-5 minutes. Keep an eye on it so that it doesn't burn.
Turn the wings over and brush with the sauce again. Broil for another 3-5 minutes.
Plate the wings on a large platter. Brush with remaining sauce for extra sauciness!
