My series on toasts from around the world has definitely included some strange combinations, but this one certainly ranks toward the top. And with a total of 45 toast recipes, that’s really saying something. Allow me to introduce you to the humble, yet delicious Fluffernutter.

Although it’s technically classified as a toast, a Fluffernutter is basically dessert. Toasted white bread is smeared with a thin layer of peanut butter (creamy or chunky) and then topped with a dollop of marshmallow creme. Kraft makes a marshmallow creme today called, “Jet-Puffed,” but one of the more popular brands is simply called, “Fluff.” The combination of peanut butter and fluff is how the toast earned its nickname: Fluffernutter.

Holly, who suggested this recipe, grew up eating this toast as a kid in the state of Massachusetts in the United States. She’s certainly not the only American kid who enjoyed this toast, but Massachusetts has a special connection to the concoction. In 1913, Amory and Emma Curtis invented what they called, “Snowflake Marshmallow Creme,” at home in Melrose, Massachusetts. The creme took off quickly with the locals because it was inexpensive, accessible, and honestly – delicious. However, Emma Curtis decided that if she could provide customers with recipes that used the creme, she could boost sales even further.

During World War 1, Emma Curtis mailed all of her customers a recipe for the, “Liberty Sandwich.” The sandwich called for oat or barley bread, peanut butter, and of course, a healthy dose of Snowflake Marshmallow Creme. This may have been the origin story of the Fluffernutter, but it wasn’t until the 1960s that the peanut butter and fluff sandwich became a proper noun. The Durkee-Mower advertising agency came up with the Fluffernutter name to help raise the sales for Fluff- the modern version of Snowflake Marshmallow Creme. After that, Massachusetts whole-heartedely embraced the toast and never looked back.

If you live outside of Massachusetts, then the idea of a marshmallow creme and peanut butter toast might not be the most appealing. But there’s just something wonderful about the sweet, creamy, gooeyness of a Fluffernutter.
