S’more Peanut Butter Cookies.

Soft-Baked S'more Peanut Butter Cookies! Bring the campfire s'mores inside with these crowd-pleasing cookies.

 Do you remember when I made S’more Chocolate Chip Cookies? Probably not; that was back when no one read my blog besides Kevin and my mom.  Well, those cookies continue to be one of our very favorite ways to eat s’mores.

Today I’m bringing you the same idea, but with peanut butter cookies instead.  Sort of like a fluffernutter sandwich.   I love those. 🙂

While there’s no graham cracker in this recipe, I still like to think of these cookies as portable little s’mores with a huge peanut butter kick. How can you resist one of these?!

 To make today’s cookies, I used one of my favorite peanut butter cookie recipes as the base. It’s my go-to peanut butter cookie dough and have so many cookies on my website using this dough as the base.  They bake up to be so soft, puffy, unbelievably thick, and the most peanutbutteriest cookies I’ve ever tasted. In fact, one reader even told me that the cookies taste like the soft peanut butter inside of a Reese’s Peanut Butter Cup. 🙂

They are so easy to make.  Many of you rave about them. Just check out all of the comments here!

Here are all of the cookie recipes I have made using my  peanut butter cookie dough base:

And I’m so excited to share my 6th version with you today. Chocolate, marshmallow, and peanut butter are just meant to be. First make my beloved peanut butter cookie dough.  I dare you to resist tasting the raw dough…

As the cookies bake, cut 12 large marshmallows in half with a knife or a pair of kitchen scissors.

Now these peanut butter cookies only take about 9 minutes in the oven to bake. However, you’re going to pull them out of the oven at the 7 minute mark and stick the cut marshmallow right on top. It’s important to watch the clock in this step!

Press the marshmallow down slightly to flatten the cookie out a bit. After you stick the marshmallow on top, place the cookies back in the oven for 2-3 more minutes. Watch the marshmallows get nice and melty over your soft peanut butter cookies.

Let the cookies cool off for a few minutes before adding the chocolate.

I always use Baker’s melting chocolate bars when I need to cover or dip something in chocolate.  Unless I add shortening, I just never have luck melting chocolate chips to a thin smooth consistency.

Any chocolate made for melting will work for the chocolate on top.

Use about 2 teaspoons of chocolate per cookie.  Just drop it on top and spread it around the marshmallow with a spoon.  The chocolate hadn’t really set yet when I photographed the cookies, so that’s why it looks extra melty. AKA: irresistible.

The sprinkles were merely and afterthought, but I just love an adorably decorated cookie. I even used some leftover heart sprinkles from Valentine’s Day for a few of them.

Start to finish, these cookies took less than an hour.  You have to let the cookie dough chill for at least 30 minutes.  As they bake, get your marshmallows ready and melt your chocolate.  Top with sprinkles and you’re done.  Wasn’t that easy?

Thick peanut butter cookie base, gooey marshmallow center, melty chocolate topping, and sprinkles for a little something extra.  I don’t think I’ve EVER had a better “s’more” in my life!

There is no combination better than peanut butter and chocolate in this world.  Unless you add marshmallow. Done and done.  We found our new favorite way to eat peanut butter cookies!

S'more Peanut Butter Cookies

Using the peanut butter recipe linked above: in a large bowl, using a hand-held mixer or stand mixer with paddle attachment, cream the butter and sugars together on medium speed. Mix in the peanut butter, egg, and vanilla (in that order). Slowly mix in the baking soda and flour. Do not overmix. Chill dough for at least 30 minutes.

Preheat oven to 350 degrees. Roll 1.5 Tablespoons of dough into a ball. Place onto ungreased cookie sheet or silicone baking mat. Bake for exactly 7 minutes. Remove from oven and place marshmallow on top, gently pressing it down into the warm cookie. Place back into the oven for 2-3 more minutes so the marshmallow can melt and the cookie can finish baking.

Remove from oven and allow to cool for about 5 minutes. As the cookies cool, melt chocolate according to package directions. Spoon about teaspoons of chocolate on top of each marshmallow and swirl around with the back of the teaspoon. Top with sprinkles if desired. Cookies remain fresh at room temperature for up to 7 days in an airtight container.

  1. Try coconut or palm oil instead of shortening with your choc chips, and melt 20 seconds at a time in the microwave (no cover). Perfect every time! 🙂 Love your recipes!!!

    • Love that suggestion Rebekah. 🙂 Thank you!

      • Sally, your description mentioned melting the chips with shortening, but I didn’t see the directions in the actual recipe…just “melt chocolate” lol. Can you tell me the ratios? Thanks. 🙂

        And I love the coconut oil suggestion Rebekah!

      • Hi Amy! My description says that I do not have luck melting chocolate chips unless I use shortening. But the recipe does not call for chocolate chips and shortening, it calls for baking chocolate – you do not need shortening to melt the baking chocolate in the recipe ingredient list.

      • Ahh, gotcha. Didn’t noticed the slight difference in wording…Just assumed it was about all CHOCOLATE! lol Thanks!! 🙂

  2. S’mores + peanut butter = my favorite cookie I’ve never made! Haha, seriously though, I’m a sucker for anything involving marshmallow, and peanut butter makes everything better. These remind me of a fluffernutter, which I have been obsessed with foreevvvverrr!

  3. These look AMAZING! Totally delectable! 🙂

  4. Sally, how do you not weigh 600 pounds? Seriously. These look insane…

  5. I love your super tall cookie dough! And the gooey marshmallow and drippy dark chocolate–YUM!! Sm’ores are one of my very favorite things and when you add peanut butter AND sprinkles–perfection!

  6. ok you are too funny with your first sentence…that is so how i feel sometimes…my family..now if i could get them to comment more. LOL so i’ve clicked over to your first smore cookies and i want to try those too…this one with the peanut butter addition that i have to try TOO!!!! they both look and sound wonderful…have you camped since then? lol

  7. I love how you have so many great base recipes. Such a great way to start off! These look so good! I love s’mores so much!

    • Thanks Stephanie! A great base cookie recipe is like a paid of shoes. If I like it, I’ll buy it in every color. If I like a base cookie recipe, I’ll make it in every which way 🙂

  8. Can I just tell you these cookies look amazing! If I give these to the kids, I am going to be a superstar! Thanks!

  9. I love peanut butter cookies on their own, but in s’more form? Wowzers. These almost make me want to try camping. And by camping, I mean staying at a hotel that doesn’t have an in-room coffee maker. 🙂

    These look awesome.

  10. Um, WOW is really the only word I can come up with for these cookies Sally! I actually love to put a peanut butter cup instead of a plain chocolate bar in my regular campfire s’mores, so I just know that I would love these cookies!

    • WHY oh why have I never put a peanut butter cup on a s’more before? Mercedes, you just opened up a whole new world of campfire s’mores for me. thaaaaaank youuuu!

  11. I adore the big scoop of chocolate on top and the sprinkles just make these look adorable! I can’t believe how easy these look to make. You are totally right about melting the chocolate chips. I wasted a whole bag and almost 30 minutes trying to get it to work over the weekend. Melting chocolate works WAY better.

  12. These are so stinkin’ cute Sally! So funny cause I’m making s’more cookies tomorrow morning! They’re not peanut butter ones though, which I might add are pure genius and just sent my taste buds into watery overdrive!

  13. Sally – I had forgotten about the original, so I’m so glad you re-posted this. There are few desserts I love as much as s’mores, but it would be so fun to have them in cookie form. Those marshmallows melt so perfectly on top – what a great idea!

  14. Hi Sally,
    Just stumbled upon your blog… love the photos! Everything looks amazing. Can’t wait to try some of your recipes 🙂

    • Hi Monica! So glad you found my site. Let me know what you make sometime!

    • Hey Monica! I just tried to leave you a comment on your blog but WP didn’t supply an option to enter/send my comment to you! I’ve seen this on many WP blogs lately. Just letting you know those tofu tostadas look wonderful!

      • Hey Sally! Hm, not sure what’s going on with WP but thanks for stopping by! The tofu tostadas were really delicious!

        So many great recipes to choose from on here but I think I will start with the chocolate peanut butter swirl cupcakes which led me to your blog in the first place 🙂 I will have to let you know how they turn out!

  15. OK, Sally, I made a variation of these cookies using Girl Scout Tagalongs. The cookies are like thick, fluffy, peanut butter clouds. I’m hooked!

  16. Can I have ‘S’more’ of these? Thanks for sharing. We just loved this recipe…brought back fond boy scout memories. Thanks again! 🙂

  17. I substituted half of the flour with whole-wheat flour and you could barely tell – it’s the little things that count!

  18. I made these last night with my 10 y.o. daughter (her favorite part was cutting the marshmallows in half). These cookies are wonderful! Truly, very good cookies. The peanut butter cookie base is pillow-y soft, half a marshmallow is the perfect amount, and using the melting chocolate on top instead of chocolate frosting is the perfect finishing touch because it adds just a touch of firmness for a nice mouth feel, and makes the whole thing non-stick (easy for the little ones to handle). I can’t believe how easy the whole thing went together as well. This recipe is going in my permanent file. Thank you!

    BTW, we used a 1 1/2 Tablespoon Wilton cookie scoop and did get exactly 24 cookies. Also our marshmallows didn’t melt over the top of the cookies, which was a bit disappointing. They puffed up really tall which was worrisome (as far as presentaion), but as the cookies cooled they settled down just fine.

    • My favorite part is to cut the marshmallows too. 🙂 Do happy to hear you and your daughter loved these, Gwen! And yes, the cookies are so so soft, which I love. And going in your permanent file? What a compliment. Thank you so much!

  19. I knoww this a silly beginner’s question. But what kind of chocolate do you melt? I understand the Baker’s chocolate I know what that is. But like semi-sweet, unsweetened, etc….?

  20. I just tried this recipe without the toppings because I wanted to test the cookie part. I accidentally left a rack of cookies on the counter overnight and they were STILL incredibly soft and moist in the morning! Can’t wait to try the other variations 🙂

  21. These cookies are delicious; everyone loved them. I made them for a cookie contest at my office and they won first place! Thanks so much for the recipe, Sally! 🙂

  22. I cannot express how incredibly delicious these cookies are! In fact, I think they taste even better a few days later. I made them for my Bunco group. But my husband is a pb cookie lover, so I’m super excited to have found a new recipe to make for him. They are so unbelievably soft! Yum. Thank you!

  23. I am in the US Navy. I’ve been following your blog for a few months and bought your cookbook as soon as I could! Everything I have tried so far has come out perfect. I occasionally bring treats to work with me and they are always gone within an hour. This is remarkable because I work in a joint service job (I work with Airforce, Marines, and Army) and, because of strict physical fitness standards, most of the people I work with are on some fad diet or another. When I bring your baked goods in, no one says no! Thanks for making our service members so happy!

  24. I was looking for a good PB cookie and combined the smore PB recipe but used half a hershey kiss on top of melted marshmellow right out of oven instead of melted chocolate since that is what I had in pantry.

  25. Hi Sally!

    Been looking around your blog and can’t wait to bake some (all) of these recipes! My question is:
    Can this s’mores peanut butter cookie recipe be used as just a plain peanut butter cookie? I only ask because it differs a little from the classic peanut butter recipe you have but you do mention that you use this recipe as a base; is that only when you use add-ins as well?

    I love peanut butter and would like a nice soft pb cookie recipe for my go to also…haven’t quite found the right one!

    Thanks for your time and all the deliciousness you introduce us to!


    • Hi Nika– I have a ton of peanut butter cookie recipes that I love. And these particular cookies are so soft. Soft and puffy and thick– they are great as a base without the s’more toppings.

  26. I feel dumb…. I can’t find the peanut butter cookie dough recipe link….

  27. I found your blog about over year ago and have since been making your recipes regularly! I preordered your book too! Your recipes never disappoint, so I knew I had to use one for my school’s cookie contest. This recipe won over the teachers and dethroned the reigning 3 time champion!! They are sooooo good! Thank you, Sally!

  28. I made the cookie dough and after it chilled I rolled it into balls and Froze it for an upcoming party. Shoukd I let dough thaw when baking or just add another minute or two?
