Making memories with food often happens by accident — it’s woven into the everyday, like the lacy crêpes my dad loved to serve on weekends or the sucre à la crème my grandma made every time she visited. School cafeterias are ripe for core food memory formation, and if you grew up in New England (or had a caregiver who did), mere mention of a Fluffernutter sandwich will bring you back.

The Fluffernutter is a classic sandwich made of soft white bread, creamy peanut butter, and gooey marshmallow Fluff. It’s been a favorite among New Englanders for decades, and here you’ll learn the history of the Fluffernutter and how to make it.

Why You’ll Love It

  • Fluffernutter sandwiches are ridiculously easy to make. You just need three ingredients: sandwich bread, peanut butter, and marshmallow crème.

  • It’s been a lunchtime staple for about a century. Once you try this beloved sandwich with a funny name but a serious following, you’ll get why it’s a classic.

Key Ingredients in a Fluffernutter

  • White sandwich bread: A Fluffernutter is not the place for seedy, nutty, whole-wheat bread. The best bread for Fluffernutters are soft and squishy white breads, like Wonder or Sara Lee.

  • Marshmallow crème: It’s easy to make homemade marshmallow crème, but the store-bought jars of marshmallow Fluff work equally well in this simple sandwich. Look for this sweet ingredient in the baking or candy aisles.

  • Creamy peanut butter: Fluffernutters classically call for creamy peanut butter as a salty, nutty contrast to the sweet marshmallow Fluff.

How to Make a Fluffernutter

Lay two slices of soft, white sandwich bread on a cutting board. Spread marshmallow crème in an even layer on one slice and creamy peanut butter on the second slice. Sandwich the fillings together and cut in half with a sharp knife. Enjoy!

History of the Fluffernutter

There are other brands of marshmallow crème, but the one New Englanders reach for is Marshmallow Fluff. It’s a gooey, sweet spreadable marshmallow made by the Massachusetts company Durkee-Mower since 1920. Despite being a preferred brand, Marshmallow Fluff was not the first marshmallow crème produced. Like many of today’s favored food products and recipes, the origin story is not always straightforward or simple.

Around 1900, siblings Emma and Amory Curtis (who also happened to be descendents of Paul Revere) invented Snowflake Marshmallow Crème (also known as SMAC). Emma was clever in her promotion of the product, sharing recipes using the sticky spread, including a 1918 recipe she called the “Liberty Sandwich” made with peanut butter and marshmallow crème. A similar recipe was shared a few years earlier in a confectioner’s trade journal.

Around the same time, the Curtises were promoting SMAC, Archibald Query of Somerville, Massachusetts, began making and selling his own marshmallow crème. His business struggled during World War I, and he sold what would become Marshmallow Fluff to Durkee-Mower for just $500. The name Fluffernutter finally came to be in the 1960s, thanks to a popular marketing campaign and sing-along jingle.

Helpful Swaps

  • Peanut butter: Creamy peanut butter is standard, but if you want to add texture, spread crunchy peanut butter on the bread instead.

  • Toast the bread: Serve this classic sandwich warm by lightly toasting the bread before adding the peanut butter and marshmallow Fluff.

  • Add something salty: Sprinkle crushed cooked bacon or crispy potato chips over the peanut butter and marshmallow Fluff before pressing the sandwich together.

  • Include Nutella: Swap the peanut butter for Nutella to add chocolate hazelnut flavor to the sweet sandwich.

Storage and Make-Ahead Tips

Fluffernutter sandwiches are best eaten the same day they are made. They can be made up to 8 hours in advance before sending to school or packing for a picnic. Stash in a zip-top bag, but because the bread and fillings are so soft, an airtight container is best for preventing the sandwich from becoming squished.
