S’mores Cookies are chock-full of everything you love in a cookie! Deliciously soft and chewy chocolate chip cookies, loaded with marshmallows, graham crackers, and melted chocolate – these are the ULTIMATE summer cookies!
All the flavors of s’mores, paired with a classic brown butter chocolate chip cookie, for an incredibly moreish soft and chewy cookie!
I can’t tell you how much I love chocolate chip cookies! Well I can, but words won’t do justice. A go-to chocolate chip cookie recipe is one of the small pleasures in life in my opinion, and I’m sure everyone has their favorite recipe. For me, that would be my double chocolate chip cookie recipe. A cookie packed with cocoa and dark chocolate chips. It gets rave reviews every single time I make it.
But my classic brown butter chocolate chip cookie is also a very close second. Without the cocoa powder, this cookie enhances the flavor of brown butter, which makes for a rich and flavorful chocolate chip cookie.
For a few months now, I’ve been trying to adapt my classic chocolate chip cookie into a classic S’mores cookie. S’mores are a classic summer favorite that I personally love to eat all year round! I used my own homemade marshmallows for this initially, but after a few tries, I realized that store-bought mini marshmallows were a better option for this particular cookie. I’ll explain why below.
Once I figured out the right type of marshmallow to use, I wanted to add graham crackers to the dough as well. This cookie not only has graham crackers embedded in the cookie, it also has graham cracker crumbs IN the cookie dough!
Ingredients to make S’mores Chocolate Chip Cookies
Brown butter
Do not skip the brown butter! It’s not that hard to do, and it makes ALL the difference in the final flavor profile of these chocolate chip cookies.
Brown butter is simply melted butter that is cooked even further, until the result is caramelized milk solids. These caramelized milk solids are suuuuper flavorful!
Sugar
I always use a combination of brown sugar and white sugar for all my chocolate chip cookies. You can use an equal amount of each, but I use slightly more brown sugar. This is because I prefer a softer, fudgier, chewier cookie. More white sugar, on the other hand, results in more crisp cookie edges.
Since I add marshmallows to the s’mores cookie dough as well, the melted marshmallows add another crunch element to the edges of the cookies. Seriously, these cookies really are a riot of flavor!
Flavoring
I add a combination of vanilla, bourbon, and salt to the cookie dough for flavor.
Vanilla and salt balance the sweetness of the cookie, while vanilla also adds a lovely sweet flavor.
Bourbon is used to replace the water that evaporates during the making of brown butter. You can use water or milk instead of bourbon, but I do love the subtle flavor of bourbon.
Eggs
I use 2 large eggs for this recipe. I haven’t tried using egg replacements in this recipe, but you could try flax seeds or chia seeds. This is because eggs act as a binder in these cookies, and flax and chia seed eggs also help with binding the dough.
Flour
I use all purpose flour. You can use bread flour or whole wheat flour as well, but these options may dry out the cookie a little, so use less of them.
Graham crackers
Graham crackers are used in multiple ways in this recipe. I use graham cracker crumbs to replace some of the flour, so that the cookie dough has a subtle nutty flavor from the graham crackers.
I also add pieces of graham crackers to the dough and place them on top of the cookie as well. This greatly elevates the s’mores flavor of the chocolate chip cookies!
Baking soda
For leavening, I use baking soda. If you want a thicker, cake-like cookie, then you can substitute the baking soda with baking powder. But I prefer a cookie that spreads a little, and is chewier, so baking soda is the right chemical leavening agent for that.
Chocolate
Use your favorite chocolate for these chocolate chip cookies. I don’t like Hershey’s chocolate, not even when making s’mores. So I use my favorite combination of semisweet chocolate and bittersweet chocolate in these s’mores cookies instead.
The semisweet chocolate bars are the same ones that I use to make s’mores. And the bittersweet chocolate wafers are my favorite chocolates that I always use for my chocolate chip cookies. I saved some of the semisweet chocolate bar to add on top of the cookies, so that they create pools of chocolate as the cookies bake.
Mini marshmallows
Mini marshmallows are the perfect way to add marshmallows to these cookies. They don’t have as much moisture, and are smaller. They mix into the dough better, and distribute more evenly as well.
However, because marshmallows are mostly sugar, they do impact the dough when they melt. The melted marshmallows make it hard for the baked cookie to hold a neat, round shape. But there’s a fix for that.
I also add some marshmallows halfway through the baking process. These marshmallows that are added later toast beautifully on the surface of the cookie. A s’mores chocolate chip cookie just isn’t a genuine s’mores cookie without a toasted marshmallow!
How to make S’mores Chocolate Chip Cookies
Brown the butter
The first step is to brown the butter. Allow the brown butter to cool down, and use it while it’s still liquid and warm, but not too hot. You can also make the brown butter the day before, and re-heat it a little before using.
Make the cookie dough
Prep and measure all the ingredients. Have them ready to go, so that there is no confusion during the recipe.
Mix the butter, bourbon (or alternative), salt, and sugars in a mixing bowl. The mixture may not look emulsified, but that’s OK. You don’t want to incorporate air and make the butter-sugar mixture fluffy.
Add the eggs. The eggs will emulsify the mixture and create a smooth, runny base. You can also add the vanilla to this mixture.
Mix all the dry ingredients together and add it into the butter-egg mix. Mix on the lowest speed.
When the dry ingredients are halfway mixed, add the chocolate and mini marshmallows. Make sure you have extra chocolate and marshmallows to top the cookies later.
Only mix the s’mores cookie dough until the flour is just mixed through, to prevent gluten formation (otherwise you’ll end up with rubbery or tough cookies).
Use a spatula to fold the dough, and make sure the cookie dough is uniformly mixed. Cover and let the dough rest for at least 15 minutes.
Brown butter and sugar being mixed together. Mix the brown butter and sugar until it reaches this creamy stage. Adding eggs to the cookie dough mix. 
The butter, sugar, and egg mixture. Adding mix-ins to the dough.
Portioning and resting the dough
Using a 3 tbsp cookie scoop, scoop portions of the dough and place them on a parchment paper-lined baking tray, OR a different container. After they’ve been portioned/scooped, place extra chocolate pieces, graham cookies, and mini marshmallows on top of each dough portion.
Here’s the hard part – I leave the cookie dough in the fridge (at least) overnight, or up to 24 hours. This resting time greatly helps with the texture of the final baked s’mores cookies. It prevents the cookies from spreading too much, and makes the flavors smooth and more blended.
If you want to store the cookies for longer, place the chilled cookie portions in a freezer bag (or ziploc bag), and freeze for later.
Baking the cookies
Preheat the oven to 350 F / 180 C, and bake 6 cookies at a time on a parchment paper-lined half sheet tray. The cookies spread as they bake, so you don’t want to overcrowd the tray. Halfway through baking, place a couple more pieces of mini marshmallows on top of each cookie.
Once baked, you may find that the cookies are shaped a little weirdly. This is because the marshmallows tend to distort the cookie shape. Some might still be OK, but others may have weird shapes. But not to worry, this can easily be fixed (see below)!
Once you’ve fixed the cookie shapes, let the cookies cool down for a few minutes on the tray. After they have cooled down slightly, transfer them onto a wire rack to cool completely.
How to maintain the shape of the s’mores cookies
The cookies will still be very soft when they come out of the oven. So you can fix the shape of the cookies right away, at this point. You’ll need to hold the baking tray with one hand, so make sure to use an oven mitt.
You will either need a large cookie cutter (bigger than the diameter of the cookie shape you want), or a small bowl. The small bowl should be easy to hold on to when upside down, and the diameter of the bowl on top should be bigger than the diameter of the cookie shape you want.
Place the cookie cutter on the baking tray, over the warm cookie, with the cookie in the middle (or place the bowl upside down over the cookie). Remember, you’re not trying to trim the edges of the cookie with the cookie cutter or bowl. Instead, you simply move the bowl/cookie cutter over the warm cookie in a circle. So that the friction of the cookie edges against the inside of the bowl or cookie cutter will shape the cookies into nice round shapes, with smooth edges. Repeat with all the other cookies while they are still very warm.
You can push all the marshmallow run off and misshapen cookies back towards the center to make nice, smooth, round s’mores chocolate chip cookies.
Once the cookies have cooled, they are ready to be eaten/served. They are fantastic while warm, or room temperature, or even chilled!
How to store s’mores cookies for later
Baked cookies can be stored in an air-tight container for up to 4 days. But remember that the longer they are stored at room temperature, the more stale they will become.
You can also store them in the fridge for about 1 week. If you want to store the cookies long term, wrap them well and store in the freezer for up to 1 – 2 months.
I personally prefer to store unbaked dough portions of s’mores cookies in the freezer, so that I can bake them fresh whenever I want! Frozen cookies should be baked for about 1 minute longer for similar results.
Substitutions and other FAQs
I advise against it. Store-bought mini marshmallows don’t melt the same way that homemade marshmallows do. Homemade marshmallows will create a larger spread in the cookies, which can be harder to fix.
Mini marshmallows, on the other hand, contain less moisture than larger marshmallows, so they don’t disrupt the shape of the dough as much either.
Yes, you can.
I would reduce the bourbon by half though. Also the taste of the cookies won’t be as deep, because brown butter really does add a lovely toasty flavor.
These s’mores cookies do spread a little. However, if your cookies spread too much (like a lace), did you rest and chill the dough? Did you use warm butter to make the dough and not hot butter? Did you add the correct amount of marshmallows to the dough, and not extra?
If you answered yes to all, and the cookies were still too thin, then I recommend using 1/2 – 1 tsp baking powder instead of baking soda to keep the cookies thicker.
Another reason could be that your oven runs too hot. If that’s the case, you can lower the oven heat by 25 F, and see if that helps.
You can replace the graham cracker crumbs with flour, or digestive biscuit crumbs.
Yes, you can. But the cookies will likely be sweeter because of the milk chocolate.
Absolutely. Just replace the bourbon with water.

S’mores Cookies (S’mores Chocolate Chip Cookies)
Ingredients:
- 226 g unsalted butter 2 sticks
- 2 tbsp dry milk powder optional
- 2 tbsp bourbon optional, replace with water if you prefer
- 200 g dark brown sugar 1 cup
- 150 g granulated white sugar ¾ cup
- 1 tsp sea salt use only ½ tsp if you prefer to use less salt
- 1 tbsp vanilla extract
- 2 eggs
- 1 tsp baking soda I only use baking soda in my cookies
- ½ tsp baking powder optional, only if you prefer softer and slightly thicker cookies
- 240 g AP flour 2 cups, measured by spoon and level method
- 100 g graham cracker crumbs
- 226 g semisweet chocolate bars 8 oz (see recipe notes), chopped
- 75 g mini marshmallows ¾ cup
- 75 g graham crackers chopped into small pieces (about ½ – 1 inch)
To top the cookies
- Extra semisweet chocolate
- Extra mini marshmallows about 3 – 4 per cookie
- Extra graham crackers chopped into small pieces (about ½ – 1 inch)
Instructions:
MAKING BROWN BUTTER
- Cut the butter into tablespoon-sized pieces. Place the butter in a saucepan over medium heat. Melt the butter in the saucepan while stirring occasionally. When the butter has melted and starts to foam, add the milk powder and stir it in (if using).
- Keep heating the butter while stirring. After a while, you will see white milk solids separating at the bottom of the pan. Use the whisk / spatula to prevent the milk solids from sticking to the bottom of the pan.
- Keep cooking the butter and stirring, until the milk solids turn a dark golden brown in color. This will happen very quickly after the milk solids turn light brown in color first, so keep stirring and don’t leave the pan unattended at this stage, to prevent the butter from burning.
- As soon as the milk solids turn dark golden brown, pour the butter into a measuring cup and let it cool to room temperature (ideally about 75°F, and still liquid).
MAKING THE S’MORES COOKIE DOUGH
- Place the cooled brown butter in the bowl of your stand mixer (or a large bowl for a hand-held mixer). Add the bourbon, both sugars, salt, and vanilla, and mix on low – medium speed ONLY until the butter-sugar mix comes together.
- Do not mix to cream the butter and sugar. It's important NOT to incorporate air into the mix, and to have a smooth mixture. If you mix too much, and add more air, the cookie dough will end up needing more flour and have a cakey texture.
- Add the eggs, and mix until just mixed through. After adding the eggs, you should end up with an emulsified mixture.
- In a separate bowl – sift the flour, baking soda, and baking powder (if using) together. Add the crushed graham crackers as well. Add the dry ingredients in two additions, while the mixer is on the lowest speed. This is to prevent the flour from flying everywhere and making a mess, and also to prevent the dough from being over-mixed. The flour doesn’t have to be completely mixed in before adding more.
- When most of the flour is mixed in, add the chopped chocolate, chopped graham crackers, and mini marshmallows, and mix on low speed until everything is mixed through.
- Remove the bowl from the mixer, and fold the mix just a few times to make sure the dough is properly mixed. Let the mixture rest for at least 15 minutes, or ideally 30 minutes, covered. IF the dough is too soft, let it rest in the fridge. It will become firm as it rests.
- Using a 3 tbsp cookie scoop, portion the cookie dough onto a parchment paper-lined half sheet pan. Don't worry about spacing here, since this is just to chill the cookie dough first.
- Add a few pieces of chocolate, 1 or 2 mini marshmallows, and a piece of graham cracker on top of each of the cookie dough portions. These chocolate pieces will melt and create pools of chocolate as the cookies bake. It's easier for the chocolate to stick to the dough while the dough is still soft.
- If you want to bake the cookies right away, you can do so (but the cookies will spread more and be thinner). For best results however, I recommend covering the sheet pan with plastic wrap and letting the cookie dough chill overnight (or at least 2 hours, or up to 24 hours).
BAKING THE COOKIES
- Preheat a conventional oven to 350°F / 180°C. Line a half sheet pan with parchment paper. Place 6 cookie dough portions on the half sheet pan, spaced evenly.
- Bake in the oven for 12 – 15 minutes. I like to bake the cookies for 12 minutes for a chewier texture with a soft middle. The exact bake time can vary depending on your oven.
- After the first 6 minutes of baking, quickly open the oven and place 1 or 2 mini marshmallows on top of each cookie, and rotate the pan, and bake for a further 6 minutes.
- Remove the cookies from the oven, and immediately shape them (as described below).
HOW TO SHAPE THE COOKIES
- Because of the marshmallows, these s'mores cookies might be a little misshapen. To shape them into nice, round shapes, use a cookie cutter or a small bowl (diameter of these should be a little larger than the cookies).
- Place the cookie cutter / bowl over the freshly baked cookie. While holding onto the baking sheet with one hand (use an oven mitt since the tray will be very hot at this point!), rapidly move the bowl or cookie cutter in a circular motion over the warm cookie. The cookie will also move around inside the bowl / cookie cutter, and this friction between the edges of the warm cookie and the inside of the bowl / cookie cutter will shape them into nice, round shapes.
- Repeat this for all the cookies while they are still soft and warm.
- Let the cookies cool for about 6 – 10 minutes on the baking tray. Then carefully remove them with a cookie spatula, and place them on a wire rack to cool down further.
- The cookies are best eaten a little warm, but they can be enjoyed at room temperature, or even chilled.
TO STORE THE COOKIES
- Unbaked cookie dough – place the chilled cookie dough portions in a gallon-sized ziploc bag or air-tight container, and store in the freezer. When you're ready to bake them, remove portions of cookie dough from the freezer and bake for 12 – 15 minutes at 350°F / 180°C.
- Baked cookies – place some tortillas on the bottom of an air-tight container. Place one layer of chocolate chip cookies on top, followed by another tortilla, and then another cookie layer. Repeat with all the cookies (using 2 – 3 tortillas). Replace the tortillas every 2 days or so (when the tortillas look like they are drying out). Cookies can be kept up to 5 days at room temperature. For best results, warm the cookies in the microwave a little before eating.
Tips & Tricks
Note about chemical leaveners
I prefer to use only baking soda. This results in a flatter cookie. If you want a softer, more cake-like cookie that is not too flat, add the baking powder along with the baking soda.Note about the chocolate
I used chopped bars, as well as chocolate wafers. I used a mix of semisweet chocolate and bittersweet chocolate. You can also use milk chocolate if you like (but this will make the cookies a little sweeter).Nutrition Information:

I made this but didn’t have time to chill them so I just popped thm in the freezer for around 10 minutes and they turned out great! I reduced 50g from each sugar type and only had 100g graham crackers lying around but it still turned out so good.
These are the best cookies I’ve ever made! My whole family loved them too.
Thank you for the recipe.
