Whisk together the soy, miso, honey, ginger, brown sugar and garlic until well combined. Put the wings into a resealable plastic bag and pour the marinade mixture over them. Seal the bag and squeeze it to coat the wings evenly. Refrigerate for at least 4 hours or preferably overnight, up to 12 hours. Preheat the oven to 375 degrees F. Line a baking sheet with a rack and spray it lightly with cooking spray. Remove the wings from the marinade, shake off any excess and spread them evenly on the baking sheet. Bake until golden brown and cooked through, 25 to 30 minutes. Transfer to a serving platter and sprinkle the sesame seeds and scallions over the top. Serve warm.
