I had never heard of a Fluffernutter until I met my husband.
As a Southern girl, I was perfectly content with a regular, ‘ol PB&J sandwich. But, my New England husband insisted on keeping marshmallow fluff in the house for Fluffernutter sandwiches.
At first, I wasn’t convinced. I mean, a marshmallow and peanut butter sandwich? Gross.
Except it totally isn’t. It won’t replace PB&J in my heart, but it is truly yummy.
For my husband, I made Fluffernutter cookies! It is a chewy peanut butter cookie with a gooey marshmallow and peanut butter center.Guaranteed to satisfy Southerners and New Englanders alike!
Note: With a couple of my cookies, the marshmallow was exposed while baking, due to the center being a bit too large. It changed the texture slightly, but it was still yummy!
- 1 cup creamy peanut butter, plus 6 teaspoons for filling
- 6 teaspoons marshmallow fluff
- ¾ cup granulated sugar
- 1 egg, beaten
- ½ teaspoon baking soda
- ¼ teaspoon salt
- Line a cookie sheet with parchment paper. Using a small cookie scoop or measuring spoon, scoop ½ teaspoon sized balls of peanut butter onto the cookie sheet. Then, scoop ½ teaspoon sized balls of marshallow fluff on top of each peanut butter ball. With damp hands, roll each ball together so you have 12 teaspoon sized balls of peanut butter and marshmallow fluff together. Freeze for about 20 minutes.
- Preheat oven to 350 degrees. Combine cup of peanut butter, ¾ cup sugar, egg, baking soda, and salt together in a medium bowl until well-combined. Chill for 10-15 minutes for easier handling.
- Using a large cookie scoop, scoop balls of dough about the size of a walnut and place a frozen peanut butter/marshmallow ball in the center. Roll the ball of dough in your hands until none of the center is showing. Place 2 inches apart on a cookie sheet lined with parchment paper.
- Bake for 12-14 minutes. Makes 12 cookies.

As a resident of the same town as Elvis, I feel confident The King would totally approve. He was a fan of the combo as well, but I think his had bananas in it. I love the combo too….marshmallow on everything!
Thanks, Susie! Bananas would be an awesome addition
I’ve never tried fluffernutter & I love marshmallows. These look amazing! Getting pinned in my sweets to try.
Definitely give fluffernutters a try! I was skeptical, but they really are tasty
Fluff cookies are the BEST. Welcome to the fluffernutter bandwagon.
Thanks, Bee!
Oh yum! I can’t wait to try. I live in CA, but picked up a big container of Fluff on my last biz trip. I love fluffernutters, and people here think I’m nuts when I make them. I can’t wait to try this recipe. Thanks!
Thanks, Nancy!
It’s been years, since I was a kid actually that I’ve eaten Marshmallow Fluff. I like the idea of it added to these PB cookies!
We always have a jar in the pantry for my husband
He doesn’t even eat fluffernutters that often, but it has to be in the house…like how I feel about Nutella 
I don’t want to sound stupid, but is there really no flour in these? I may have to make these for my husband this weekend!
Nope, no flour! It results in a flatter cookie, but it makes for a much simpler recipe
I am DEFINITELY in for making these then!
I was introduced to flutternutter sandwiches in college. Coincidentally, it was by a friend from New England too! I’ve keep a jar of fluff in my house ever since. Thanks for the cool cookie recipe!
Thanks, Mike! They are like missionaries, spreading the word of this weird and amazing sandwich
I have never had a Fluffernutter sandwich, but I think a Fluffernutter cookie would be the way to go!
YUM!
You simply must give it a try, Sue! It is an interesting experience
I know a number of people who would be thrilled with a plate full of these tempting treats. As a child I wasn’t thrilled with peanut butter (or pb&j, for that matter), but I loved fluffernutter sandwiches!
Yay for fluffernutters!
Fluff is amazing! Great cookies
Agreed!
Oh how I love Marshmallow Fluff! I love peanut butter almost as much so I need to try these. Thanks for sharing
Pinning now!
Thanks, Lisa! It is an awesome combination!
These sound totally scrum-diddly-umptious Jennifer!
Thanks, Janine!
Unfortunately, my country isn’t advanced enough to provide wonders like marshmallow fluff
Any ideas on how I can whip up an alternative?
Hi Beth! They are some recipes for homemade marshmallow fluff around the web, like this one: http://www.chow.com/recipes/30296-homemade-marshmallow-creme. I’ve never made it before though! Hope that helps.
I have heard of fluffernutter, and know what it is, but have never tried it. In cookie form thought I would love it! Wish I hadn’t made a promise to myself that I wasn’t going to bake anything until we got back from Japan!
As yummy as they are, they definitely can’t compete with JAPAN!!
Oh my gosh, these look so genius! I’ve never tried peanut butter and marshmallow together, but it sounds amazing!
You have to give it a try sometime, Elizabeth!
So yummy!
What a wonderful cookie! I will have to try this!
Thanks, Nicole!
These sound really yummy! I’m just a little confused on the # of cookies. It says that there will be 12 teaspoon size balls for the center, but then at the end it says it makes 24 cookies. So do you need to make 24 teaspoon balls or split the 12 in half to fill the cookies?
Oops! Thanks so much for pointing that out Natalie! The recipe makes 12 cookies, not 24. I have updated it now
Fluffernutter – it even sounds fun not to mention yummy!
Very true, Kim!
Yummy, your cookies look really good!
Aww, thanks Rosie!
Amazing! I’ve never had a fluffernutter cookie either but I’m sure these will change my life.
You should definitely give it a try, Chung-Ah!
Oh my, those look and sound so good! I love pb and marshmallow together – it’s actually become one of my favorite flavor combinations recently.
Thanks, Laura!
My son is going to love these!
Thanks!
Hope you like them, Kel!
Fluff was a staple in my NY home growing up! I loved fluffernutter sandwiches or on crackers after school! Can’t wait to try this recipe! Thanks for the yummy memories!
Thanks, Sami!
I Love stuffed cookies! I’ve never seen this trick with the frozen marshmallow fluff – neat!
Thanks, Amanda!
Fluffernutters are a commonly accepted thing in the north that I always ate as a kid…and still occasionally as an adult…but now living in Virginia, I get some crazy looks when I talk about it haha My boyfriend absolutely refuses to try a fluffernutter sandwich so I’m hoping maybe these cookies will help sway his mind haha They are delicious and being that I am gluten intolerant as well, the fact that these are made without flour is a huge plus! Thanks so much for posting this recipe!
Aww, you’re welcome! It sounds like a fluffernutter cookie would be a fine transition into a full-blown fluffernutter sandwich
I found this recipe on Pinterest and as an avid fluffernutter eater as a kid, I just had to make them!!
I made these cookies two nights ago to bring into work and everyone loved them!! The cookies did turn out HUGE tho! Since the recipe said it makes 12, I planned to make 2 dozen. The first dozen I followed the recipe exactly and those ones turned out really big. The next batch I decided I should cut the frozen fluff/pb balls in half and used half the amount of dough to get 2 dozen cookies. These cookies were still kind of big but thinner – still delicious tho!
Next time I think I will just stick to the recipe exactly but only put 6 on the cookie sheet at a time to give them some more room to spread out and not smoosh together.
Simple, quick and delicious cookies!! Thanks so much for sharing the recipe!!
I’m so glad that you liked them, Jamie!
I made these today — and also did some with Nutella and Marshmallow Fluff. They taste phenomenal…the feedback from my family was awesome (very moist, chewy and delicious). The only mistake I made was making the centers too large — which then created monster sized cookies. Big cookies aren’t normally a huge issue, but because the centers are so soft from the filling – many collapsed on my cooling racks. I did leave them on the pan (out of the oven) for longer than normal — more like 5 minutes vs. 2…but I lost a lot of them. Next time I will just be more thoughtful about how large the fluff/peanut butter centers are and let them cool on the pan just a bit longer (7 minutes?) then it will be perfect.
Good news is that the messy ones tasted just as good! Thanks for the phenomenal recipe.
I’m so glad you enjoyed them! I am sorry for the lost cookies – the size definitely matters for the middle! I tested a couple with larger centers and they were massive and never quite solidified! I’ll be sure to update the recipe to reflect that
