Hello folks! If you’re a fan of peanut butter and Fluff sandwiches these Fluffernutter Bars are for you!
Seriously, they’re irresistible!
I’ve been super swamped lately guys. The BHK has been keeping me busy AND as I’ve previously mentioned our new puppy Bodie has us on our toes 24/7. I guess I just forgot how much work a puppy can be and at my age I think my stamina for keeping a puppy entertained is not what it should be. Wah wah.
So some days I just need to reward myself with a little treat. That’s where these Fluffernutter Bars come in.
I was thinking something peanut butter. And I’ve always been a fan of Fluff in my hot cocoa, so I decided for all the peanut butter and Fluff sandwich lovers I’d throw together a bar that would incorporate both.
I know I’ve mentioned it here on the blog before, but I did not grow up eating peanut butter and jelly sandwiches. We always had a jar of peanut butter in our cabinet, but surprisingly I probably never had a PB&J until I met my husband Tom. And peanut butter and Fluff sandwiches were not on my radar either, but boy do peanut butter and Fluff taste dee-lish baked into a buttery bar! And top them with a few Nutter Butter Cookies and they’re even more decadent.
Fluffernutter Bar Ingredients
- creamy peanut butter
- unsalted butter
- light brown sugar
- large egg
- vanilla extract
- all-purpose flour
- kosher salt
- Nutter Butter Cookies
How To Make These Fluffernutter Bars
You’ll only need less than 10 ingredients and minimal time to throw these beauties together. First, you will cream some peanut butter together with some unsalted butter until it’s nice and smooth followed by the addition of some light brown sugar, a large egg and some vanilla extract.
Once you’ve incorporated those ingredients, you’ll add your flour and kosher salt and mix until just combined. You’ll spread half the mixture into your parchment-lined 8×8 baking pan, followed by some Fluff. You’ll smooth the Fluff with a spatula and then top with the remaining cookie dough. The bars will bake for about 25-30 minutes at 350 degrees.
They go perfectly with a tall glass of cold milk. Hope you give them a go!

A Few Cook’s Notes for Fluffernutter Bars
As with any cookie bar recipes, I make sure not to overbake. I like my bars moist and chewy, not dry and hard. I baked these for 25-30 minutes or until a tester inserted in the middle of the bars came out mostly clean with just a few crumbs.
You will need an 8×8 pan for this recipe.
I used the full sized Nutter Butter Cookies (as pictured) to top my bars with, but you could also use their Nutter Butter Bites if you’d like.

Fluffernutter BarsPrint Recipe Pin Recipe
- 1/2 cup unsalted butter, room temperature
- 1/2 cup creamy peanut butter
- 1 cup light brown sugar
- 1 large egg, room temperature
- 1 tsp. vanilla extract
- 1 1/2 cups all-purpose flour
- 1/2 tsp. kosher salt
- 1 cup marshmallow Fluff
- 6-8 Nutter Butter Cookie Sandwiches
- Preheat oven to 350 degrees. Line an 8x8 baking pan with parchment paper. Spray parchment lightly with nonstick cooking spray. Set aside.
- In a large bowl, cream together butter and peanut butter until smooth, 1-2 minutes. Add the brown sugar and continue to mix until smooth.
- Add the egg and vanilla and mix until well combined. Add the flour and kosher salt and mix until just combined and no streaks of flour remain.
- Add half of the cookie dough to your prepared pan and smooth out with an offset or rubber spatula. Top the dough with a layer of the marshmallow Fluff and then dollop the remaining cookie dough on top of the Fluff, smoothing gently with your spatula. I find spraying the spatula with some nonstick cooking spray makes it easier to spread evenly. Lightly press a few Nutter Butter Cookies into the top. (as pictured)
- Bake for 25-30 minutes, until lightly browned on top. Mine took 30 minutes. Remove to a wire rack to cool. Once cool, cut into bars.
