Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
Pat chicken wings dry with paper towels.
In a large bowl, toss wings with baking powder, salt, and pepper to coat.
Arrange wings in a single layer on the baking sheet.
Bake for 30 minutes, then flip wings and bake for another 20-30 minutes, until cooked through and crispy.
While wings bake, prepare the glaze. In a small pot, combine gochujang, honey, soy sauce, rice vinegar, sesame oil, garlic, and ginger.
Heat glaze over medium heat until simmering. Cook for about 5 minutes, stirring occasionally, until slightly thickened.
Remove wings from oven and brush generously with gochujang glaze.
Return wings to oven for 5-10 minutes, until glaze is sticky and caramelized, watching carefully to prevent burning.
Let wings cool slightly before serving.
