Marshmallow cream, often called marshmallow fluff, originated in the United States in the early 20th century as a convenient, shelf‑stable alternative to traditional marshmallows. It became popular in classic American treats like s'mores, fluffernutter sandwiches, and as a frosting for Baked Alaska.

While the basic recipe is consistent nationwide, some regions add a pinch of salt or use corn syrup instead of granulated sugar for a smoother texture. In the Northeast, marshmallow fluff is famously paired with peanut butter in the "fluffernutter" sandwich.

It is most commonly spread on sandwiches, used as a topping for s'mores, folded into frosting for cakes, or lightly toasted with a kitchen torch over desserts like Baked Alaska for a caramelized finish.

Marshmallow cream is a staple at summer camp cookouts for s'mores, at holiday gatherings for Baked Alaska, and at casual brunches where fluffernutter sandwiches are served.

It pairs beautifully with chocolate brownies, banana splits, layered cakes, and fruit tarts. It also works as a light frosting for angel food cake or as a dip for fresh strawberries.

The classic recipe uses egg whites, granulated sugar, cream of tartar, and vanilla extract. Acceptable substitutes include aquafaba for egg whites (vegan), lemon juice or white vinegar for cream of tartar, and maple or almond extract for vanilla.

Common errors include not heating the mixture to the proper 160°F temperature, using a bowl with any grease or moisture, and stopping the beat before stiff peaks form. Each of these can result in a grainy or runny texture.

An instant‑read thermometer provides a quick, accurate reading of the soft‑ball stage (160°F) without the need for a long‑stem candy thermometer, making it easier for home cooks to verify the correct temperature.

Yes, you can make it up to two weeks ahead. Store it in an airtight container in the refrigerator. For longer storage, freeze it for up to two months and re‑whisk after thawing.
