Add the baking powder and salt to the wings. Stir to coat.
Spray a baking rack with nonstick cooking spray and place on top of a foiled sheet pan. Distribute wings evenly on top, making sure none of them touch and they are all face-up.
Bake for 35 minutes, then increase the temperature to 425˚F/220˚C and bake for an additional 45 minutes, or until wings are crisp and golden. (Do not remove the wings from the oven when increasing temperature.)
Remove from oven and toss wings in Teriyaki Sauce.
In a hot pan, bring soy sauce to a boil.
Stir in brown sugar and honey.
Add in sesame seeds and stir until slightly thickened and bubbling.
