Fluffernutter Cookies, 3 Ingredients!

Tags: , ,

Phew, what a whirlwind this week has been! I need one of these cookies while I unpack! More about my trip later, we’ve got to talk cookies!

Seriously, wait until you try this recipe. I am literally talking 3 ingredients and about 5 minutes of prep before they are in the oven! Woo Hoo!

I have had this idea in my head for over a week now and had NO idea how they would turn out. Peanut butter and marshmallow are 2 of my favorite ingredients so I had to play around with a cookie! Come to find out they are awesome! My oldest said, Mom these are the best cookies in the whole world! Ok I wouldn’t go that far, but for as easy as they are…yes they are super yummy!

Grab a tall glass of milk and treat the family to these way too easy and oh so fun cookie gems! Hope you all enjoy 🙂

Yes, you heard me right….3 ingredients! Peanut Butter, marshmallow cream and a Large Egg 🙂

Mix, mix, mix

Ready to bake!

Bake 12-15 minutes

Fluffernutter Cookies

1 Cup creamy peanut butter

1 large egg

1 cup marshmallow cream

1. Preheat oven to 350 degrees F. In a large bowl mix the peanut butter and egg until well combined with a spoon. Slowly stir in the marshmallow cream until just combined. You want to see the marshmallow cream not fully incorporated, almost like swirled through. With a small-medium cookie scoop, scoop dough onto a parchment or silpat lined baking sheet. Bake for 12-15 minutes or until baked through. Let cool for 5 minutes on cookie sheet before transferring to a cooling rack. Definitely grab some milk with these bad boys and Enjoy!!

about 18 cookies


Have a great rest of your week and weekend! Stay tuned for pictures of my trip and as always new recipes!!

      I too had a large jar leftover from holiday fudge making, seen this recipe and sooo… YUMMLY good.

      Salad & a Cookie, I rather like that. For me its a beer & a cookie.

    I wish they sold marshmallow fluff in the UK….maybe they do and I don’t know about it! These look gorgeous.

      Hey Helen,

      I know that London definitely has fluff but I don’t know about the rest of the UK! I just got back from doing my college semester in Italy (where they did not have marshmallow fluff). While I was abroad, I went to the UK for a long weekend and saw fluff in one of the grocery stores and actually brought it back to Italy with me haha!

      mmm I love fluffernutters!

      I know this is from 2 years ago, but they sell marshmallow fluff at ASDA! Just thought you should know in case you haven’t figured it out yet 🙂

    I had all the ingredients on hand so my 2 year old twins and I just whipped up a batch. I’m excited because my mom is a HUGE fluffernutter fan and she is child sitting for us and now she can enjoy this little treat while she’s here! And WHEN (not if) she runs out she can just make up another batch, they were so quick and easy. Thanks!

    How did you know that Fluffernutters were in my top 5 guilty pleasures? These are GREAT! Talk about the easiest cookies…um…ever? Can’t wait to give these a try!

    this look amazing. i grew up eating fluffernutter sandwiches and now my kids eat them. of course, it’s a crime that we can’t get marshmallow cream here. this recipe is definitely on my have to make list.

    Could you add chocolate to them?

      Hailey says:

      you could switch out the peanut butter for Nutella, or do half peanut butter half Nutella! If you are allergic to nuts, I’m sorry, I can’t help with that :/ this was 5YEARS ago though, so maybe you have already figured this out?

        Tammie Ames says:

        Actually there is something that you can use in place of Peanut Butter, Sun butter. I use it in place of Peanut Butter for Recipes and it is delcious. Find it in the Health Food Section or a Health Food Store. It is a little Pricey but well worth it if you are Allergic to PB like me and want to still feel like you aren’t missing out on Everything!
