Mix all the ingredients (except chicken) together in a bowl, make sure to mix well.
Put the chicken in a large zip top bag and dump the sauce mixture over the top of it as well. Seal and store in the refrigerator for 24 hours, mix it around a couple times during the process. We often marinate it right in the baking pan we are going to use to cook it, just cover it well.
If you marinated it in a bag, dump it all in a baking dish. Cover it and bake it in the over at 350 degrees for 1.5 hours.
