Peanut Butter S’mores Bars {no bake!}

I got invited to a last minute shindig and was asked to bring a dessert.  I wanted to do something quick and easy, but also fun and impressive.  I love the *ahh* factor, but hate to spend the time to get it.  So I grabbed this simple no-bake peanut butter bar recipe from the fabulous ladies over at Six Sisters’ Stuff and jazzed it up a bit.

The result?  Magic.  People ate these things up.  Literally.

I’ve had about a billion people ask for the recipe since then and I’m a little embarrassed at how easy it is.  But these things are pretty much heaven on a plate, so I guess I’m not too surprised.

Love these?  Try my Peanut Butter Cup Cookie Brownie Bars {it’s like peanut butter and chocolate on overload}, or check out the rest of my desserts!

Peanut Butter S'mores Bars {no bake!}
Prep time: 
Total time: 
  • ½ - 1 cup butter
  • 2 cups graham cracker crumbs
  • 2 cups powdered sugar
  • 1¼ cups peanut butter
  • 1 can marshmallow fluff
  • 1 bag semi-sweet chocolate chips
  • 1 bag mini peanut butter cups
  1. Melt ½ cup butter in the microwave.
  2. Mix butter, graham cracker crumbs, powdered sugar, and peanut butter together until completely combined. If the mixture is not sticking together, add additional ½ cup of butter gradually to combine until crust sticks together but is not too sticky.
  3. Press into the bottom of a 9x13 pyrex.
  4. Spread a layer marshmallow fluff over the graham cracker crust.
  5. Melt the chocolate chips in the microwave. Pour over fluff layer and spread to create a full layer.
  6. Coarsely chop the mini peanut butter cups and sprinkle on top.
  7. Refrigerate for an hour or more to let the chocolate set {you can also throw it in the freezer if you're in a hurry}.
  8. Cut and serve!

Note: I’ve had several readers say that the crust turns out too soft.  It worked for me with one cup of butter, but I’ve updated to give options to make sure that it turns out perfectly for everyone!

  5. Wow!! Looks absolutely amazing. Pinned and can’t wait to make them 🙂

  6. Can’t wait until the weekend when I can try this recipe!

  7. Your photos make my mouth water! I’ve bookmarked this page and will be trying this recipe very soon.

  8. What type of butter do you suggest? Margarine or Unsalted butter?


  9. I can’t believe that a gorgeous slice like this can be no-bake!! Genius! Love the flavour combination – definitely a teensy bit (okay, a lot) indulgent but definitely worth it 🙂 I’ll be making these for my office morning tea next week. Woop, love that I won’t need to turn the oven on (living in Australia, the oven gets excruciating in our house sometimes) x

    I made these today and the crust is like mush. Not sure why. I even double checked all my measurements. They taste good, but I can’t serve them to company 🙁

    • Oh my I’ve never had this problem before! What kind of peanut butter did you use? Did you try chilling them in the fridge or freezer for a bit to let it set more?

      • i just made these and am having the same problem with my crust? there is no way i am going to be able to “press” it into the bottom of the pan. is there really suppose to be 1 cup of melted butter? any suggestions on how to fix this???

        • Chelsea says:

          I’ve had the same problem both times I’ve made these. I’m wondering if its suppose to be 1/2cup butter instead of a full cup. Maybe ill try that next time I make them.

  11. do you think I can use Rolo’s instead of mini peanut butter cups?

  12. I think my son would love these!!! How big of a container of fluff do you use? The 71/2 ounce or the 16 oz? Thanks!

    • I use the 7 oz container. Enjoy!

      • Going to make these friday. Another question: when you say 1 bag of the mini reece’s cups, did you use the 8 ounce bag with the unwrapped mini’s or the 12 ounce bag of the minis that are individually wrapped? Also, unsalted butter or salted? Many thanks!

        • I used the 8 oz bag with the unwrapped candies and salted butter. I hope you enjoy them!! And please see the note above about the amount of butter…the recipe worked just fine for me but I’ve gotten some feedback that it was too loose for others so you may want to start with a little less butter and then add if needed. Good luck and I hope you enjoy!!

          • We loved this! 1/2 cup butter worked for me!

          • Brielymar says:

            Just tried these today. Much MUCH too sweet! And I even used 1/2 of the amount of sugar the recipe called for. I think the sweetness of the fluff ruined it. Otherwise, it would be a good recipe.

    keep doing what you’re doing!

  15. It is not my first time to visit this site, i am visiting this web site dailly
    and get pleasant information from here everyday.

  16. If I can’t find any marshmallow fluff can I just melt a bag of marshmallow in a double boiler? Thanks!

    • I haven’t tried that before, but you could try! I would just give the marshmallows a little extra time to reset before moving on to the next layers so that the next ones don’t smooth all of the marshmallow out. It should only take a few minutes…marshmallow usually re-solidifies pretty quick. Let me know how it works!

  18. All of the best things in one dessert! Great Summer treat!

  19. My Venue 8 3830 has a lot of WebView issues (known issues, c’mon Dell)
    and I guess I’m simply dreaming this may fix them.
