Easy Cream Filling (Donut) (10 servings) 1 cup shortening 1 cup confectioners sugar 1 cup white sugar Whip together all ingredients until creamy (about 10 minutes with an electric mixer). How's that for easy! Makes almost a cup and a half. I recommend using an electric mixer. It takes a lot longer if you do it by hand. This is the recipe most donut shops use because it's so inexpensive. Mr Breakfast would like to thank Jazzbo for this recipe. Recipe number 1108. Submitted 10/23/2003.
