What Is A Fluffernutter?
If you’ve never had a fluffernutter, you are in for a real treat. I remember having fluffernutter sandwiches growing up, and now I make them for my kids all the time. A fluffernutter sandwich is made with equal amounts of creamy peanut butter and marshmallow cream/fluff served on white bread.

Tips And Tricks
- If you don’t have a medium and small cookie scoop, you can use a measuring spoon to scoop out the dough and marshmallow cream.
- Scooping the marshmallow fluff onto the cookie dough can get a little messy. I found that if you wet your finger before scooping the fluff onto the cookie it comes out a lot easier.
- Be sure to flatten the cookie dough out enough that it wraps around the marshmallow fluff completely.
- The thinner the cookie dough is wrapped around the marshmallow the more the cookie will crack when baked. You don’t want it to be too thin, but you do want it wrapped around the marshmallow cream.
- If your cookies come out of the oven misshapen, you can form them back into circles with the edge of a spatula while the cookies are still warm.
- Be sure to chill the dough for at least 30 minutes. If you don’t, it will be harder to flatten dough into a disk and wrap around the marshmallow.
Storing And Freezing Peanut Butter Cookies
Storing: Fluffernutter cookies are best stored in an airtight container in a single layer at room temperature. Be sure not to stack cookies on top of each other because the marshmallow fluff stays sticky.
Freezing: Baked cookies can be frozen in a single layer in an airtight container for up to 2 months. Just set them on the counter to thaw. Enjoy!

Well mine were apparently delicious but came out pretty flat. I had the dough in the fridge AT LEAST 45 minutes and it was still so sticky I couldn’t roll it into balls. What did I do wrong?
You want to make sure your flour is measured correctly, your butter is not melted, and place them on parchment paper or a silicone baking sheet. You can try spraying your hands with nonstick cooking spray and then placing them back in the fridge to chill after you roll them into balls.
Can you replace AP Flour, BS & BP with self rising flour?
I have not made these cookies with anything other than all purpose flour, I would love to hear how they turn out if you try with self rising flour.
I saw these cookies on Pintrest and had to try them. They were so good!!! It’s the perfect sweet and salty combination, the cookie part is not too dry (which happens sometimes with peanut butter cookies, am I right?!) and really tastes just just a fluffernutter. I chilled the dough AND the fluff for an hour while I ran to the store. I was out of parchment paper, so I used aluminum foil on a baking sheet, it worked out fine. (They probably would rise more on the paper) I sprayed some cooking spray on my finger tips which made the fluff even easier to manage. I used a measuring spoon for the fluff and probably used a little less than a tablespoonful for each cookie. I chilled the prepared balls in btw batches, they came out great! I was tempted to leave them in the oven for longer than 10 minutes but I realized that the fluff would just keep expanding if I did. I will definitely make these again!
I’m so glad you loved them, they are one of our favorite cookies to make. Thank you for sharing.
Ooooohhhhhh mmmmyyyyyyy. Those look scrumptious! I’ll have to make those for my kiddos!
