Where Did Fluffernutter Come From?
The Fluffernutter sandwich has a history dating back to the early 20th century. Marshmallow Creme came about in the early 1900s. In 1918, Emma Curtis created the “Liberty Sandwich,” a combination of peanut butter and marshmallow creme on oat bread. She shared this recipe in a promotional booklet for her customers.
The term “Fluffernutter” came later, in 1960, when an advertising agency used it to market the sandwich. Since then, Fluffernutter has grown into a popular treat, especially in New England.
Ingredients Notes
- Peanut Butter: Creamy peanut butter makes the bars smooth and rich. You can use your favorite brand.
- Marshmallow Fluff: Marshmallow Fluff is the key to the gooey topping. It adds sweetness and a marshmallow flavor.
- Butter: Use unsalted butter at room temperature. It helps create a tender base.
- Brown Sugar: Light brown sugar adds moisture and a caramel-like flavor.
- Flour: All-purpose flour provides the structure for the bars.
- Vanilla Extract: Pure vanilla extract enhances the overall flavor.
How to Make Fluffernutter Bars
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper. The parchment paper makes it easier to remove the bars later.
Step 2: Cream Together
In a large bowl, mix together the softened butter and peanut butter until smooth.
Step 3: Add Sugar
Add the brown sugar and mix until the mixture is light and fluffy.
Step 4: Incorporate Egg and Vanilla
Mix in the egg and vanilla extract until well combined.
Step 5: Add Dry Ingredients
Gradually add the flour and salt. Mix until just combined, being careful not to overmix.
Step 6: Press into Pan
Press about two-thirds of the dough into the prepared pan. Make sure the layer is even.
Step 7: Spread Marshmallow Fluff
Spread the marshmallow fluff evenly over the peanut butter base.
Step 8: Add Remaining Dough
Take the remaining dough, make small flat discs, and place them over the marshmallow fluff.
Step 9: Bake
Bake for 25-30 minutes, or until golden brown.
Step 10: Cool
Let the bars cool completely in the pan before cutting into squares.
