I didn't have any confectioners' sugar, but I needed to make frosting. Who knew you could use sweetened condensed milk? I must confess, I varied this recipe a little and added 1/2 cup or so of strawberries and 16 ounces of cream cheese (2 blocks). I also didn't have shortening and made this with all butter. I will post the recipe the way I found it at cooks.com. Serving size is estimated.
