Easy Peanut Butter Cookies with Marshmallow and Chocolate

Pull out your fat jeans kiddos. Seriously, before you read this post, go pull them out of the closet. Or if you are already in them leave this post immediately. These cookies were soooo good. As you all know from the Fluffernutter Cupcakes I have a love of Fluffernutter things. And even more so when they include chocolate in some way. So when I saw that Amy over at Sing For Your Supper came up with the idea for these cookies…I just knew I wouldn’t be able to resist.

So in order to prepare for the splurge, I have been eating a lot of ass friendly dinners and I planned the cookies to coincide with the same week of the 5K I am doing this weekend. Because between eating good for a week and the 5K this weekend I don’t have to feel bad about not having any cookies leftover to send into Jorge’s office.

I actually do feel kind of bad for not sending any of these in to his office because they were so amazing! I really, really want you all to try these! They were incredibly easy to put together and are now probably my favorite cookie, ever. And that is saying something! But I honestly mean it. Are you ignoring me? If I type in all caps will you pay more attention? Because I mean it, MAKE THESE. If you like peanut butter, chocolate, and marshmallows (and really, who doesn’t?!), MAKE THESE NOW!

Prep Time 35 minutes
Cook Time 10 minutes
Total Time 45 minutes


For the Fluffernutter Cookies

  • 1/2 cup (1 stick) unsalted butter, softened
  • 3/4 cup peanut butter
  • 1/2 cup white sugar
  • 1/2 cup packed brown sugar
  • 1 egg
  • 1 teaspoon vanilla extract
  • 3/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 3/4 cups all-purpose flour
  • regular marshmallows, sliced in half lengthwise (to be added to the cookies after the first round of baking)

For the Chocolate Glaze

  • 3/4 cup semisweet chocolate chips
  • 3 tablespoons butter
  • 1 tablespoon light corn syrup
  • 1/4 teaspoon vanilla extract


Make the Peanut Butter Cookies

  1. Combine the flour, baking soda and salt in a bowl, set aside. In the bowl of a stand mixer or with a hand mixer, beat the butter, peanut butter and sugars for 2 minutes, until light and fluffy. Add in the egg and vanilla. Gradually add in the flour mixture on low speed. Chill dough 15 minutes in the refrigerator.
  2. Place by rounded spoonfuls on a cookie sheet lined with parchment paper and bake in a preheated 350 degree oven for 7-9 minutes, until edges are very lightly browned (cookies will not spread much at all). Do not overbake.

Make the Chocolate Glaze

  1. In a double boiler over hot, but not boiling water, combine chocolate chips, butter, and corn syrup. Stir until chips are melted and mixture is smooth, then add vanilla.

Assemble the Cookies

  1. As soon as the peanut butter cookies come out of the oven, place 1 marshmallow half on the top of each cookie (you may need to flatten the cookies slightly with a spatula first). Place them back in the oven for 2-3 minutes, until the marshmallow is melted. Let cool completely.
  2. When completely cooled, spoon a small amount of chocolate glaze over the top of each cookie. Glaze will set slightly upon cooling.


Recipe Note: The recipe says they make 2 dozen cookies…but apparently I make ginormous cookies, because this made 12 cookies for me.

    this sounds incredible! the only question i have is about the marshmallows: do you buy the mini marshmallows or the jumbo (or does it depend on how big the cookies are)? i ask because i’m not too sure what you meant by ‘regular-sized’ marshmallows

  2. Lucie (Thursday Night Dinner)

    the only thing i ate for lunch all through middle school fluffernutter sandwiches! fI have to try this out.

    A batch of these flutternutter cookies is cooling in the kitchen and it looks and smells fabulous- can´t wait to paint the chocolate on it.
    Thank you so much and greetings from Switzerland!

  4. Sarah in Miami

    Sorta unrelated, but we call my dog Fluffernutter because she’s fluffy and totally crazy! My sister will be delighted to learn there are multiple incarnations of the word.

    In other news, I gotta go make these ASAP…. =)

    How fun! These sound like s’mores with a twist. I know these wouldn’t last very long if they were anywhere near me…!

  6. Honeybee Sweets

    I first thought the pics look amazing, and it sounds amazing, but I wasn’t dead set on making these. HOWEVER, after reading the post, you’ve definitely talked me into it. I can’t wait to try them!! Thanks!

  7. Rachel @ The Avid Appetite

    oh.my.goodness. these look like heaven on a plate. the only thing better than pb and chocolate is adding fluff to the mix!

  8. Yanni Robel

    So I work at allrecipes.com, and I stared on recipes of goodies ALL the times, but not once, I am drooling to one. Until looking at this one at your blog. I’ve been doing good on my WW diet, so this will be my treat and will have no guilt on eating them. Thank you for posting this. Hugs.

    I just finished putting on the chocolate glaze! You are right, YUM! These are definately my new favorite! Definately worth putting on my far jeans for!!!

  10. Dionne @ Try Anything Once

    I was introduced to a “fluffernutter” sandwich by a former co-worker. It was good, but these cookies look WAY better! Can I have one? I need it for with my coffee. 🙂

  11. Joanne

    I had fluff and PB sandwiches ALL THE TIME as a kid! Which possibly explains why I was wearing fat pants then. Hmmm. Need this cookies in my life.

  12. Lauren at Keep It Sweet

    I haven’t had a fluffernutter in years, but this seems like the perfect excuse to bring the flavor combo back into my life!

  13. Happy When Not Hungry

    Wow these look delicious! My favorite sandwich as a kid (ok and maybe today) is peanut butter and fluff. Definitely will be trying these cookies!

  14. Lisa (Dishes of Mrs. Fish)

    Um, could you please deliver this to my house for breakfast? Thanks. I’d love you forever. 🙂
