Fluffernutter bars are a delightful combination of peanut butter and marshmallow fluff, inspired by the classic Fluffernutter sandwich. These bars are sweet, gooey, and packed with nostalgic flavor, making them perfect for any peanut butter lover.
Ingredients
1/2 cup unsalted butter, melted
1 cup brown sugar, packed
1 large egg
1 teaspoon vanilla extract
1/2 cup creamy peanut butter
1 cup all-purpose flour
1/2 teaspoon baking powder
1/4 teaspoon salt
1/2 cup marshmallow fluff (plus more for swirling)
1/2 cup peanut butter chips (optional)
1/2 cup mini marshmallows (optional)
Instructions
Preheat the Oven: Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal.
Make the Batter: In a large bowl, whisk together the melted butter and brown sugar until smooth. Add the egg, vanilla extract, and peanut butter, and mix until well combined.
Add the Dry Ingredients: Sift in the flour, baking powder, and salt. Stir the mixture until just combined, being careful not to overmix. If using peanut butter chips, fold them into the batter at this stage.
Layer the Batter: Spread about two-thirds of the batter evenly into the prepared baking pan. Drop spoonfuls of marshmallow fluff over the batter and use a knife or skewer to gently swirl it into the batter. If you’re using mini marshmallows, sprinkle them on top.
Top with Remaining Batter: Drop spoonfuls of the remaining batter over the marshmallow layer. Gently spread it out to cover the fluff and marshmallows as much as possible.
Bake: Bake in the preheated oven for 25-30 minutes, or until the bars are set and lightly golden on top. A toothpick inserted into the center should come out with a few moist crumbs.
Cool and Serve: Allow the bars to cool completely in the pan before cutting them into squares. Serve them as a sweet treat with a glass of cold milk or a cup of coffee.
Tips for Perfect Fluffernutter Bars
Don’t Overbake: To keep the bars chewy and gooey, make sure not to overbake them. They should be slightly underdone in the center when you take them out of the oven.
Use Creamy Peanut Butter: For the smoothest texture, use creamy peanut butter rather than chunky. However, if you like a bit of crunch, feel free to use chunky peanut butter.
Extra Marshmallow Fluff: For even more gooeyness, add extra marshmallow fluff on top of the batter before baking.
Variations
Chocolate Drizzle: Drizzle melted chocolate over the cooled bars for a chocolatey twist.
Nutty Fluffernutter Bars: Add chopped peanuts or pecans to the batter for a bit of crunch.
Conclusion
Fluffernutter bars are a fun and indulgent treat that captures the essence of the beloved Fluffernutter sandwich in dessert form. With their rich peanut butter flavor and gooey marshmallow swirls, these bars are sure to become a favorite in your household. Perfect for bake sales, potlucks, or just satisfying a sweet tooth, these bars are easy to make and impossible to resist.
