Saco Powdered Buttermilk works perfectly in these cinnamon rolls. Powdered buttermilk is a good ingredient to keep on hand for when you are out of milk.
If you'd rather use a cream cheese glaze, beat together 4 oz of softened cream cheese, 3 tablespoons confectioners' sugar and about 1-2 tablespoons warm milk or as much needed for a drizzling consistency. Flavor with about ⅛ to ¼ teaspoon vanilla extract.
