Ingredients
Here’s what you’ll need to make these irresistible Fluffernutter Bars:
- 1 cup unsalted butter, melted
- 2 cups graham cracker crumbs
- 2 cups powdered sugar
- 1 cup creamy peanut butter

Directions
1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
2. In a medium-sized bowl, combine the melted butter, graham cracker crumbs, powdered sugar, and salt. Mix well until the ingredients are fully combined and resemble a coarse crumb texture.
3. Press two-thirds of the crumb mixture evenly into the bottom of the prepared baking pan to form the crust.
4. In a separate bowl, mix together the peanut butter, marshmallow fluff, and vanilla extract until smooth and well combined.
5. Spread the peanut butter and marshmallow mixture evenly over the crust in the baking pan, using a spatula to smooth it out.
6. Sprinkle the remaining crumb mixture on top of the peanut butter and marshmallow layer, gently pressing it down.
7. Bake in the preheated oven for 25-30 minutes or until the edges are golden brown.
8. Remove from the oven and let the bars cool completely in the pan before cutting into squares.
9. Serve and enjoy these irresistible Fluffernutter Bars!
Notes
Experimentation is key! Feel free to play around with the ingredients and customize these bars to your liking. You can try using different types of nut butter or adding a sprinkle of sea salt on top for a salty-sweet twist.

Variations
While the classic Fluffernutter Bars are hard to beat, I’ve tried a few variations that were equally delicious. One time, I substituted almond butter for peanut butter, and it turned out to be a delightful alternative. Another time, I folded in some crushed pretzels into the marshmallow layer for an extra crunch. The possibilities are endless, so don’t be afraid to get creative!
Equipment
To make these Fluffernutter Bars, you’ll need a 9×13-inch baking pan, a mixing bowl, and a spatula. If you don’t have a baking pan, you can use a similar-sized oven-safe dish or even a square cake pan as a substitute. Don’t let the lack of specific equipment stop you from enjoying these incredible bars!
Storage Information
Although I highly doubt these Fluffernutter Bars will last long in your house, they can be stored in an airtight container at room temperature for up to 5 days. However, in my experience, they tend to disappear within a day or two because they are just that irresistible!
Serving Suggestions
I personally love indulging in a Fluffernutter Bar with a tall glass of cold milk. The creamy, salty-sweet combination is simply divine. If you’re feeling extra indulgent, you can even warm up a bar in the microwave for a few seconds and top it with a scoop of vanilla ice cream. It’s pure heaven!
Pro Tips
Through trial and error, I’ve learned a few valuable lessons when making these Fluffernutter Bars. One tip is to make sure you let the bars cool completely before cutting them. This will ensure clean and neat squares. Additionally, if you find the marshmallow fluff layer too sticky, try lightly greasing your spatula with cooking spray to make spreading easier. Trust me, it makes a world of difference!

A: While I haven’t personally tried freezing them, I don’t see why not! Just make sure to store them in an airtight container or wrap them tightly in plastic wrap before placing them in the freezer. When you’re ready to enjoy them, let them thaw at room temperature for a few minutes before indulging.
Q: Can I use homemade marshmallow fluff?
A: Definitely! If you’re feeling ambitious and want to make your own marshmallow fluff from scratch, go for it! Just keep in mind that the texture and sweetness of the bars might slightly vary depending on the homemade fluff recipe you use. Have fun experimenting!
