After making my chocolate marshmallow cookies (which by the way, my brother said was the best cookie he's ever had!) I knew I wanted to make a s'mores version! These are the same super fudgy and chocolatey cookies stuffed with mini marshmallows, chopped chocolate and graham crackers.
It's just like having a super chocolatey s'more but in cookie form! If you wanted more of a classic chocolate chip s'more cookie you can try my chocolate chip and marshmallow cookies! If you want an even more chocolatey version of these cookies, you have to try making my fudgy triple chocolate chunk cookies made in one bowl!
Why I can't stop making these cookies!
- Super Easy - these are a really simple cookie to make. You need one bowl to make them.
- Packed with S'mores Flavor - with a combo of chopped chocolate, crushed graham crackers and mini marshmallows you're getting all the s'mores flavor you know and love.
- Rich & Fudgy - my husband Will said these cookies had a super rich chocolate flavor, he said they actually reminded him of hot cocoa!
Recipe Testing
These chocolate s'mores cookies are based on my chocolate marshmallow cookie recipe. When testing them, I found that they were a teeny bit too dry when they weren't stuffed with a marshmallow, like in the original recipe. I added an extra egg yolk which made them softer and chewy. This is the same chocolate cookie recipe I use in my cosmic brownie cookies!
Grab Your Ingredients
- Cocoa Powder: make sure to use dutch processed cocoa powder! Natural cocoa powder reacts differently with baking soda and baking powder, so you can't swap it out. It also makes the cookies very rich with a great chocolate taste.
- Leaveners: you'll need both baking powder and baking soda.
- Graham Crackers: crush up your favorite graham crackers!
- Chocolate: I chopped up a chocolate bar but you could swap it out for semisweet chocolate chips if that's all you have on hand.
- Marshmallows: I'm using mini marshmallows that way you get a lot more marshmallows in every bite. You can swap them out for regular marshmallows but I recommend chopping them up.
How to Make Chocolate S'mores Cookies
Step 1: In a stand mixer, mix together the butter, granulated sugar and light brown sugar until light and fluffy. Then add the vanilla extract, egg and egg yolk.
Step 2: Mix in the flour, cocoa powder, salt, baking powder and baking soda. Mix until just combined.
Step 3: Stir in the crushed graham crackers, chopped chocolate and mini marshmallows. Chill for 30-60 minutes in the fridge. While chilling, line two baking sheets with parchment paper.
Step 4: Using a spoon or a large cookie scoop, scoop out 3 tablespoons of cookie dough and place on the prepared baking sheet. Bake in an oven preheated to 350ºFahrenheit for 8-10 minutes.
Ella's Baking Tips
- Chill Cookie Dough - I recommend chilling the cookie dough if possible! It will help the cookie not spread out too much when baking. I did skip chilling the cookie dough with my cosmic brownie cookies which use the same cookie base and they were fine, so if you like to live dangerously you can skip the chilling.
- Add Extras - add extra marshmallows and chopped chocolate to the top of cookie dough balls just before baking to get that bakery style cookie.
- Bake One Sheet at a Time - I recommend baking one cookie sheet at a time and placing the other sheet in the fridge until ready to go into the oven.
- Cookie Scoot - my favorite trick to get perfect looking cookies! Once the cookies are out of the oven, use a large biscuit cutter or a mug to gently scoot the cookies into a perfect shape.

Alisa says
This has a good flavor, but I could tell midway into making it that it was going to be a very dry cookie. This doesn't need that much flour, and the butter likely needs to be melted and mixed, then the refrigeration will help it firm up.
Ella Gilbert says
Hi Alisa, I'm so sorry about that! Do you mind letting me know if you used cup measurements or metric measurements? I've tested these cookies quite a few times and they aren't a very dry cookie dough so I'm wondering if you maybe added too much flour or cocoa powder? Let me know!
Susie says
They look so good! What kind of kosher salt? Coarse kosher salt or fine kosher salt?
Ella says
Hi Susie! If you check out the notes in the recipe card, I mention I use Diamond Crystal Kosher Salt which is a fine salt. I only ever use fine kosher salt or regular table salt, coarse kosher salt would be too salty! If you don't have fine kosher salt, swap it out for regular salt but just do half the amount listed in the recipe card.
Susie says
Thank you. I went back and looked at the notes. I just made these cookies. So delicious!
Ella says
I'm so glad you liked them!
Denise Y Samson says
Can I use slightly stale graham crackers?
Ella Gilbert says
Hi Denise! I haven't tried that, but I think it would work. Let me know if you try it!
Micah says
Hello🌸. I'm unsure of the steps when freezing.
Should I include the marshmallows, chocolate and crackers, in the mixture that will be rolled into balls and placed in the freezer?
Or should I put the bowl of unrolled mixture (excluding the marshmallows) into the freezer. And freeze the mallows separately, only adding them to the mix once the balls are being rolled, pre being baked?
Sorry if this is confusing, I just want to make sure I'm doing what's best.
Ella says
Hi Micah! I'm so sorry about that, I've fixed it for you - you need to mix the cookie dough with the mix-ins (including the mini marshmallows!) and chill it in the fridge. Then you can scoop it out and bake on your baking sheet. No need to freeze mini marshmallows! I've found it easier to chill the dough first, then scoop into balls, otherwise it's a bit too sticky.
Micah says
Hii. Wow that was fast, thank you for getting back to me so quickly!
I'm going to make the recipe today and bake them on Monday. My last question is; should I do everything as you said,the only difference being that it will go into the freezer rather than fridge? - And roll the balls on Monday.
Ella says
Hi Micah! I haven't tested these by chilling them for that long! You can freeze the cookie dough balls and bake them - I have notes in the recipe card for that 🙂
Gabrielle says
Very good cookies and very easy to make! I will be making them again 🙂
Ella says
Thanks so much for your review Gabrielle!
