Preheat your oven to 375 degrees. Arrange wings in a shallow baking pan.
Heat butter, soy sauce, sugar, broth or water, mustard powder, garlic powder, & honey in a saucepan on low until the butter is melted & the sugar is dissolved. Remove from the heat & set aside to cool.
Once the sauce has cooled, pour it over the chicken wings. Cover with foil & refrigerate for 2 hours or up to overnight, being sure to turn at least twice.
Bake in the same pan for one & a half hours. Cook longer if they are really big chicken wings, if needed.
