S'mores cookies are a delicious twist on your favorite campfire treat! These cookies are soft and chewy, filled with graham crackers and chocolate, then stuffed with gooey marshmallows for the ultimate s'mores dessert. Trust me, everyone will fall in love with these s'mores stuffed cookies!
The Challenge
Don't know if you've noticed, but I kind of have a deep love for cookies. I also have a fondess for challenges.
While browsing online, I came across a few recipes for cookies stuffed with marshmallows which looked out-of-this-world incredible, but every single comment on the recipe notes that unless they used vegan marshmallows, the marshmallows would disappear.
Now, I don't have any issues with vegan marshmallows. They taste okay, but the texture isn't my favorite. Every vegan marshmallow I've tried always seemed a bit tough and a little too chewy.
Personally, I prefer soft and fluffy marshmallows, but I can certainly see how they would be able to stand up against the heat without any issues. My main concern here is the fact that not everyone is going to have ready access to vegan marshmallows and not everyone will want to have to order them online or make their own.
What are s'mores cookies?
These s'mores cookies are made with my favorite chocolate chip cookie with a serious upgrade. This soft, chewy cookie with crisp, buttery edges is kicked up a notch with graham crackers, chocolate, and stuffed some marshmallows for a gooey, fun filling that will have everyone going back for more.
They're the cookie you need to make as often as possible.
Ingredients
First, you need the basic ingredients to make a deliciously chewy cookie. These are:
- Unsalted butter - We use unsalted so we can control the amount of salt. The butter adds richness, plus gives us those delicious buttery edges we can't resist.
- Sugar - We use brown and granulated sugar to give us just the right amount of sweetness and chewiness.
- Eggs - Eggs bind the cookie dough, add moisture for easier rolling, and adds richnes.
- Flour - I always use all-purpose flour. You can also substitute some of the all-purpose flour with whole wheat flour.
- Salt - I prefer to use fine sea salt in my recipes. If you want to top the cookie dough with salt, I recommend a flaky sea salt like Maldon.
- Leaveners - Baking powder and baking soda give the cookies some rise and a wonderful texture.
- Ground cinnamon - Optional. I like it to emphasize the cinnamon in the graham crackers.
- Vanilla extract - I recommend using a nice pure vanilla extract. You can also use vanilla bean paste.
Then, you need the ingredients to turn them into s'mores cookies, which are:
- Chocolate - Chopped chocolate or chocolate chips work. I like to use a mix. For a real s'mores flavor, add some chopped Hershey's milk chocolate bars in the mix.
- Marshmallows - I get asked a lot why I say you need to use mini marshmallows instead of a single large marshmallow. The answer is because of the coating around the marshmallow. That coating actually helps prevent the marshmallow from disappearing too fast while baking, so mini marshmallows give us more coating than one large marshmallow.
- Graham crackers - This is probably my favorite part of s'mores. I like having my graham crackers crushed to varying degrees. Some readers also suggest sandwiching your marshmallows between two small graham cracker pieces to further protect them from disappearing.
The secret to s'mores stuffed cookies
The trick, as it turns out, is two fold:
- to get the dough as cold as possible without freezing them
- getting the s'mores cookies to cool quickly, without putting them in the refrigerator
I tried using frozen marshmallows, but they thaw as you put them in the cookie dough, so it is pointless. But cooled dough keeps the marshmallows cool enough while the cookie bakes. Cooling the cookies quickly also means the marshmallows aren't in the heat too long which is what makes them disappear.
Making your cookie dough balls
When you form the s'mores cookies, it is also important to keep the top cookie thinner than the bottom. The marshmallows will be able to stand the heat while in the oven when they are a little more exposed.
The thinner top allows the marshmallows to lower their temperature faster once they are out of the oven. Which is the critical part. You can put these cookies by a window or near a fan to help the process.
I have also noticed that there is a difference between how you bake them. These cookies bake better in a convection oven and you are almost guaranteed success if you are using a convection oven (or using "convection bake" if your oven has the option of doing that or just "bake").
Non-convection ovens tend to need a longer bake time and can dissolve the marshmallows more easily. I recommend checking on the s'mores cookies every minute past 8 minutes if your cookies still look very raw at the top.
Please also note that, in general, s'mores stuffed cookies will look underbaked. This is normal. We want them underbaked, because that's what makes them soft and chewy. They continue to bake while on the baking sheet.
S'mores stuffed cookies take a little extra time and love to make, but they're worth it.
Trust me, they are worth it.

- 1 teaspoon ground cinnamon optional
- 1 cup 227 grams butter, room temperature
- ¾ cup 165 grams brown sugar
- ½ cup 100 grams granulated sugar
- 1 large egg room temperature
- 1 large egg yolk room temperature
- 1 teaspoon 5 grams vanilla extract
- ⅔ cup 117 grams semi-sweet chocolate chips
- ½ cup 88 grams roughly chopped milk chocolate
- 1 cup 50 grams mini marshmallows, for dough
- 2 cups 100 grams mini marshmallows, for filling
Instructions
- Mix together flour, salt, cinnamon, baking soda, and baking powder. Set aside.
- Break up the graham crackers into small pieces. Be careful to not let it get too powdery, but some graham cracker powder is okay. Set aside.
- Cream the butter and sugars together until fluffy.
- Slowly add the egg and yolk one at a time, then the vanilla. Beat well, then slowly add the flour mixture and beat until just incorporated.
- Fold in the graham crackers, chocolate, and mini marshmallows.
- Take a tablespoon of the cookie and create a small indentation.
- Stuff 4 - 5- mini marshmallows into the indentation. Make sure they are TIGHTLY packed in. Top with another 2 teaspoons of cookie dough and press together until the dough completely covers the marshmallows. Repeat with the remaining dough and marshmallows. Top the finished cookies with additional chocolate and/or marshmallows to make them prettier, if desired!
- Place the cookies on a baking sheet and cover. Cover with plastic wrap and chill in the refrigerator for at least an hour, preferably overnight, up to three days.
- Preheat the oven to 350°F.
- Uncover the cookies and bake for 8 - 9 minutes or until a light golden brown.
- Use a spatula to remove the cookies to cool on a wire rack. For the best results, place the cookies near a fan to cool them quickly.
- Serve immediately or store in an airtight container and enjoy within 24 hours.

Notes
- Cheat the recipe: Roll the cookie dough without the marshmallows into balls 2 tablespoons big. Bake for 8 - 10 minutes. Once cooled, toast marshmallows and use the cookies to sandwich them.
- Some readers said they prefer sandwiching a large marshmallow with two small squares of graham crackers to help prevent the marshmallow from disappearing.

Does it wont be good after 24 hours?
Amanda says
They'll taste fine, but the marshmallow in the middle tends to disappear after 24 hours!
Karen G says
This cookie is AMAZING!!!! I wasn’t sure about the wheat flour but it all works!!!!! Definitely will make these again!!
Denise says
These look wonderful! Do they really need to be eaten in 24 hours? Exited to try them!
Kendal says
So I was super excited about this recipe. However, as I was making the cookies, the dough came out really crumbly and does not hold together. Am I doing something wrong?
Amanda says
You might have accidentally overmeasured the dry ingredients (it’s an easy thing to mistakenly do unless you weigh the ingredients). An easy fix it to add a tablespoon or two of milk until the dough comes together better!
Kendal says
Okay, thanks so much!
Aym says
Helloo amazing recipie! Btw how long would this last once baked which I highly doubt it would last fr too long ,lol but I want to make this ahead and store airtight?
Amanda says
It should last at least 3 days, but most people find the marshmallow filling disappears by then!
brooksms says
I know this is old but just wondering...what's the theory behind wanting the marshmallows to cool quickly after baking? I've never put them in cookies before so I'm not familiar although I have heard they can disappear!
Amanda says
So the reason is because we don't want the sugar in the marshmallows to retain heat as it will dissolve into the cookies. Marshmallows are really just whipped sugar with a bit of gelatin, so the heat will alter the state of the sugar if it is kept like that too long!
Ayesha says
Can I substitute all purpose flour instead of whole wheat?
Amanda says
You definitely can!
Naila says
What will happen if I just cook it the same day? I'm in a rush and i need to know if they'll be the same or not. Please answer me when you see this.
Amanda says
As long as it has a one hour chill time it should be okay

I am sorry Judy, we switched our programming that stores the digital recipe cards. It may not have transferred when we imported. I will review the card and update.

Disappointment.
Was excited to make these for a luncheon with the fellow members of the Ladies’ Yacht Club. So imagine my disappointment when I take these out of oven and find they look like the rash on my dog’s rectum.
Marsha Langman one-upped me once again with her famous Turkey Casserole. I hope you’re proud. I had one chance to prove myself and you repay me like this. You don’t deserve the right to call yourself a baking blog. Good Day.
Lori says
So, you tried a new cookie recipe for a luncheon without making them first to see how they turned out? And you blame her? You had your chance to prove yourself by making the cookies before so you could make any needed adjustment. I hope you're proud for the way you commented. Marsha Langman probably made her famous turkey casserole a million times, so she deserved to one up you. You don't deserve to comment when you're as rude as you are. And don't you think it's time you got over your jealousy of Marsha? Tell her it tasted great instead of having your claws come out. Just laugh at the cookie error, which was obviously your fault, and eat them, even if they looked like the rash on your dog's rectum. Good day.
Aysegu says
These cookies are just AWESOME. It was so hard to resist eating them all in one sitting. 🙂
Ann says
These are amazing. I needed 7 graham crackers, and made life simpler by removing two from the package of nine, crushing the crackers inside their plastic packaging, and adding them to the recipe. Then I could just replace the extra crackers. I used one regular and one special dark Hershey's bar, a half-cup seemed like an awful lot of chopped chocolate and the balance was nice. I also tore one large marshmallow in half to press into the dough on top of one small marshmallow; it was easier to manage. The recipe yielded 18 cookies which is honestly too many for two people, plan to share!
Kayla McClure says
Just made these! They are great. May have to add more Marshmellow's next time!
Jeun says
Hi!! I would really like to bake these, but i dont have wheat flour handy.. 🙁 can i do a substitute or omit it..? Thanks so much for sharing!!
Amanda says
You can replace it with all-purpose flour instead!
Kendra says
I'm in the process of making these... so far so good. I have them made up already and just waiting on the kids and hubby to have dinner before a pop them in the oven.. thank you very much for this recipe.. I think it'll be a hit...
