The History of Fluffernutters:
The Fluffernutter Sandwich is a peanut butter and marshmallow creme sandwich served on white bread. It was first created in the early 20th century (during WWI) after marshmallow creme was invented in Massachusetts.
Emma Curtis invented Snowflake Marshmallow Creme in 1913. She sent the recipe for this peanut butter and marshmallow cream sandwich out to customers in 1918. It’s believed that this is the origin of the idea for this sandwich.
The sandwich was dubbed as the “Fluffernutter” by an advertising agency in 1960.
Fluffernutter is now a registered trademark of Durkee-Mower, covering ice cream and printed recipes sold as a component of food packaging and cookbooks. Durkee-Mower is the Marshmallow Fluff company. In 2006, Durkee-Mower sued Wiliams Sonoma for infringing upon their trademark by selling a marshmallow and peanut butter candy under the Fluffernutter name.
How to make Fluffernutter Bars:

Take the pan out of the oven and sprinkle in remaining cookie dough and spoonfuls of Marshmallow Creme. Bake again.
