If you purchased your wings frozen, be sure to allow ample time for them to defrost.
Line a large casserole dish (you may need 2 dishes depending on the size you have) with foil. You will be wrapping the chicken completely in foil, so allow enough to completely cover the chicken all the way around.
Place your wings in the foil and be sure they are single layered.
Pour the oil over the chicken and mix the chicken in the dish to completely coat it with the oil.
Sprinkle the chicken with the garlic powder and onion powder.
Pack the foil around the chicken so that it is sealed on all sides.
Bake in oven for 50 minutes.
While the chicken bakes, combine all sauce ingredients in a medium mixing bowl with a whisk. (Be sure to whisk again just before pouring over your chicken.)
Remove the wings from the oven, open the foil (don't burn yourself with steam), and pour off any liquid in the bottom of the foil.
Pour your sauce over the chicken.
Turn your oven to broil.
Place the chicken back in the oven UNcovered, for 10 minutes. Watch the wings carefully. If they need to be removed in less than 10 minutes, do so. You just want to brown them a bit and get the sauce to sear just slightly on to the meat.
Remove from oven, allow to cool and place in a serving dish, being sure to pour any sauce left behind in the dish over the chicken.
Notes
Please note that the nutrition data is a ballpark figure. Exact data is not possible. Note that you can cut down on the nutritional content considerably by using boneless, skinless chicken breasts instead of wings.
