Quick Benefits

Fluffernutter bars are a delicious combination of creamy peanut butter and marshmallow fluff, creating a dessert that’s both indulgent and easy to make. Perfect for parties, potlucks, or a sweet snack, these bars are a guaranteed crowd-pleaser. Plus, they only require a few simple ingredients and minimal preparation time, making them ideal for any busy baker.

Essential Ingredients

Base:

  • 3/4 cup unsalted butter, melted
  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 3/4 cup creamy peanut butter
  • 1/2 teaspoon salt
  • 1 1/2 cups all-purpose flour

Frosting:

  • 1/2 cup unsalted butter, softened
  • 1 7-ounce container marshmallow fluff
  • 2 cups powdered sugar
  • 1/2 cup chopped peanuts

Preparation Steps

  1. Preheat the oven to 175°C (350°F). Grease a 9×13-inch pan with nonstick cooking spray and set aside.
  2. In a large bowl, mix the melted butter, brown sugar, and granulated sugar using a hand mixer until blended. Add eggs and vanilla extract and mix until fully incorporated. Then mix in the peanut butter until smooth.
  3. In a separate bowl, whisk together the salt and flour. Slowly add the dry mixture to the wet mixture and mix until just combined.
  4. Spread the batter evenly into the prepared pan. Bake for 25–30 minutes, or until golden and a toothpick inserted in the center comes out clean. Let the bars cool completely after removing them from the oven.
  5. In a large bowl, beat the softened butter and marshmallow fluff together. Gradually add powdered sugar, one cup at a time, until blended and smooth.
  6. Spread the frosting evenly over the cooled bars and sprinkle chopped peanuts on top. Cut into portions and serve.

Health Benefits

While Fluffernutter bars are undeniably a treat, they do offer some nutritional perks. Peanut butter is a great source of protein and healthy fats, while marshmallow fluff provides a touch of sweetness without overwhelming calories. Opting for unsalted butter and minimizing added sugars can also make these bars slightly more balanced.

Serving Suggestions

Serve these fluffernutter bars with a cold glass of milk or a hot cup of coffee. For an extra twist, drizzle some melted chocolate on top or pair them with a scoop of vanilla ice cream for a decadent dessert.

Creative Variations

  • Chocolate Chip Fluffernutter Bars: Add a cup of chocolate chips to the batter for a gooey, chocolatey version.
  • Crunchy Twist: Swap creamy peanut butter for crunchy to add texture.
  • Gluten-Free Option: Substitute all-purpose flour with a gluten-free blend.

Storage Tips

Store the bars in an airtight container at room temperature for up to three days or in the refrigerator for up to a week. For longer storage, freeze individual portions wrapped in plastic wrap and store in a freezer-safe bag.

Pro Tips

  • Always use room-temperature ingredients for a smoother batter and frosting.
  • Line your baking pan with parchment paper for easy removal.
  • Allow the bars to cool completely before frosting to avoid melting the buttercream.

Frequently Asked Questions
