Marshmallow creme is an American food item. It is a very sweet, spreadable, marshmallow-like confection. Marshmallow creme and peanut butter are used to create a fluffernutter sandwich. In addition, marshmallow creme and Nutella can be spread on graham crackers to emulate s'mores.
One popular brand of marshmallow creme, sold principally in the Northeastern United States, is Marshmallow Fluff, manufactured by Durkee-Mower, Inc.. It is also available in Canada and in some European supermarkets (Scandinavia, Germany, the United Kingdom, Belgium) in standard, raspberry and strawberry flavour. Its ingredients consist of corn syrup, sugar syrup, vanilla flavour, and egg whites. Ricemellow Creme, manufactured by Suzanne's Specialties, Inc., is a common vegan equivalent.
