Flourless Peanut Butter Nutella S’Mores Sandwich Cookies are ridiculously fun, ridiculously good, ridiculously large (if we are being perfectly honest), and it would be ridiculously silly if you didn’t make them! Nutella and marshmallow buttercream, sandwiched between two super peanut-buttery cookies.

Food blogger secret – make one basic recipe, split it up and make several variations. Then, spread the posts out just enough, or use one as a guest post on someone else’s blog, and WHAM – holiday time saver! Sorry, it’s that time of year, we all have to cut corners. And I’ll tell you, you can probably cut corners with this recipe and use a jar of marshmallow fluff, but the marshmallow buttercream is just one of the most unique and fun recipes I’ve tried, so give it a shot.

And then get ready to have your mind blown. Flourless peanut butter cookies just have the most intense peanut butter flavor, and since they are tender and not too sweet, they are perfect for sandwiching gooey, chocolaty Nutella and a fluffy marshmallow buttercream. This is seriously like a bite (a very large bite – these aren’t dainty cookies) of heaven, because I don’t know about you, but my version of heaven has marshmallow clouds, and flowing rivers of peanut  butter and chocolate. Basically, you know, Willy Wonka.

Another holiday time saver – make up a batch of Flourless Peanut Butter Nutella S’Mores Sandwich Cookies, wrap them up individually with some pretty cellophane and ribbon, and freeze them.

If you receive an unexpected gift or overnight guest, wrap a couple up with a cute holiday mug and some hot cocoa mix. They are actually pretty easy to make, and once you get the assembly line going, don’t take very long, either. But they look impressive and taste, well, as I said…  ridiculous!!

Flourless Peanut Butter Nutella S'Mores Sandwich Cookies

Take S'Mores to a new level with Nutella and marshmallow buttercream sandwiched between two flourless peanut butter cookies. These Peanut Butter Nutella S'Mores Sandwich Cookies are irresistible!
Prep: 20 minutes
Cook: 10 minutes
Total: 30 minutes


For the Flourless Peanut Butter Cookies:

  • 1 cup sugar
  • 1 cup dark brown sugar
  • 2 teaspoons baking soda
  • 2 cups natural peanut butter
  • 2 eggs
  • 2 teaspoons vanilla

For the Marshmallow Buttercream:

For assembling the S'Mores sandwiches:

  • 1 1/2-2 cups Nutella (about)
  • 2 cups Marshmallow Buttercream or 2 cups marshmallow fluff (about)


For the Flourless Peanut Butter Cookies:

  • Preheat your oven to 350°F. Line cookie sheets with parchment paper.
  • Using a fork, mix together the sugar, brown sugar, and baking soda in a bowl.
  • With a hand mixer or stand mixer, beat in the peanut butter until cream.
  • Add the egg and vanilla and mix thoroughly.
  • Form balls using about 1 tablespoon of dough, place on the cookie sheet and flatten slightly with you hand.
  • Bake for 10-12 minutes, or until lightly browned and set.
  • Cool on the baking sheet for several minutes before transferring to a rack to cool completely.

For the Marshmallow Buttercream:

  • In a small saucepan over low heat, combine the milk and marshmallows and gently melt, stirring occasionally. Set aside to cool.
  • Using a hand mixer, cream the butter until light and fluffy.
  • With the mixer running, slowly pour in the marshmallow mixture and vanilla. At this point, it may start to look like it has separated a bit.
  • While continuing to whip the frosting, gradually add the powdered sugar and whip until light and creamy.
  • Use immediately.

For assembling the S'mores sandwiches:

  • Spread about 1/2-1 T Nutella on one of the peanut butter cookies, and about 1 T marshmallow buttercream or marshmallow fluff another cookie and sandwich together gently.
  • Store sandwich cookies in the refrigerator (or freeze until needed).

    I would so love to win…. BTW: Keep up the awesome recipes !!!! Thanks for the opportunity, you are awesome !!!!!!!!

  2. Melissa

    I would make a pie crust in the food processor. I’ve always had a hard time with those but I feel like this will be my year.

  3. LOVE, love, LOVE that flourless cookie!!! We have a similar version that is a family favorite, but I’ve never gone so far as to make them a sandwich cookie. This could be a new favorite in our house, I’m thinking!!

    I would love this as my processor is on it’s way out. I enjoy making healthy LC, GF breads and goodies. I also use my processor to make oat flour and nut flours. I use it daily!

    A Cheese Ball! I’ve had the recipe for years and have always loved it, but never had the right equipment to pull it together!

  6. Diana Cote

    peppermint brownie pops sound good. I would love to make some dough for soft homemade doughnuts or ice cream. 🙂

  7. Stephanie

    OMG! I would love to try making these cookies! They would definitely be the first thing I make if I win this food processor! They’re perfect for the holidays haha 🙂

  8. Cairn

    Cookies sound yummy and the food processor would be great. I have been wanting one. Thanks for the chance to win!

  9. Doreen McCloskey

    I have wanted a food processor for such a long time and would use it a lot! I’d make salad dressings, a chocolate torte with biscotti crust, pie crusts, breads, and definitely making many of your great recipes here. You really have great recipes and I appreciate them!! Thank you!

  10. jackie

    I would definitely make the recipe above. Those look amazing! Currently not having a food processer makes me unwillingly skip over recipes like this, which I hate doing 🙁 trying to make recipes without a food processor and a blender and just using my hands doesn’t always turn out in my favor, and is just a pain in the butt.

  11. Carly

    I can’t wait to try this recipe on Saturday! They look so amazing.
    I will make some fresh pesto with the magimix.

  12. Kristi Wolfe

    I could sooo use this since the switch on mine is broken and I have to plug and unplug mine in order to use it 😉

  13. Susan Broughton

    I think i will make your cookie recipe. I am looking for a variety of cookies to give to my friends for Christmas so I am going to give your recipe a try.

  14. I freaking love these cookies Brianne. I need about 3 dozen of these in my life right now. Love the pics too.

    Thanks so much for joining us for Christmas Week. I’m so happy you are doing this with us. xx

  15. Theresa

    So many recipes to make and try. Cookies, probably! The peanut butter Nutella s’mores sound really good. All of my kids love Nutella, so I’m sure they would like them.

  16. Rae

    These looks so easy and yummy! I can’t wait to try the marshmellow frosting! How oozy is it? Would it hold up on cupcakes?
    If I won the food processor id make a nice dense cheesecake and then some of my mom’s lemon squares
