Chances of having leftover berry cream are slim, but just in case: Refrigerate 1 to 2 days and use to top pancakes, ice cream, pound cake, brownies or shortcake.
To prevent waffles from sticking, season the waffle iron according to the manufacturer’s directions. After each use, remove all traces of baked-on batter or crumbs.
