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!
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.
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.

- 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.
