S’mores Brownies
These S’mores Brownies are super fudgy chocolate brownies swirled with marshmallow fluff and milk chocolate chips, baked on a graham cracker crust, and topped with toasted mini marshmallows.
I want to write a novel about these s’mores brownies because they are so ridiculously good that they deserve it. Just look at the gooeyness on these babies! These are hall-of-famers for us s’mores lovers and the brownie lovers alike.
S’mores flavored anything always scores major points in my book, and I made a s’mores brownie recipe a few years ago that never made it onto the site, but I have most definitely never forgotten them. These are a recreation of those, and they definitely satisfied the s’mores brownie craving.
Let me paint a picture of these s’mores brownies for you: thick, crumbly graham cracker crust, just substantial enough to support the rich, fudgy brownies. The brownies are swirled with marshmallow fluff and have a generous helping of milk chocolate chips throughout. Top that off with mini marshmallows. Toast them for a few minutes to puff up and get all s’mores-y and toasty, just the way you like ’em. For an extra hit of chocolate, sprinkle more milk chocolate chips on top and let them melt into the marshmallows.
This is good stuff, friends. I haven’t had an appetite since I’ve been sick, but I’m wishing I could snatch one of these s’mores brownies out of the screen right now.
How many s’mores brownies does this recipe make?
This brownie recipe is an old favorite that I love because it makes a smaller batch of 16 brownies. My usual go-to brownie recipe makes a 9×13-inch pan of brownies, whereas this one makes an 8×8-inch pan. Using the smaller-sized pan is perfect for super decadent brownies like these. If you’re baking for a crowd though, simply double the recipe and make them in a 9×13-inch pan.
The brownie batter comes together quickly in the microwave. It uses cocoa powder instead of chocolate, but they are most definitely not lacking in chocolate flavor. They are gooey and fudgy, which the swirled in marshmallow fluff certainly helps us achieve.
These S’mores Brownies have everything you’d want in a s’mores brownie. I recently served these when we had some people over. They were literally gone within 3 hours of getting out of the oven! …much to the dismay of my housemates who missed out on having one before they all disappeared. My favorite comments from the notebook this time around: “These brownies are a mouth orgasm” and “these are brownies from the Gods”. If that doesn’t convince you, I don’t know what will. Enjoy!

Description
These S’mores Brownies are super fudgy chocolate brownies swirled with marshmallow fluff and milk chocolate chips, baked on a graham cracker crust, and topped with toasted mini marshmallows.
Ingredients
For the graham crust
- 4 tablespoons unsalted butter, melted
- 1 cup graham cracker crumbs
For the brownies
- 10 tablespoons (1¼ sticks) unsalted butter
- 1¼ cups (8¾ oz) granulated sugar
- ¾ cups plus 2 tablespoons (2½ oz) unsweetened cocoa powder
- ¼ teaspoon salt
- 1 teaspoon vanilla extract
- 2 large eggs
- ½ cup (2¼ oz) all-purpose flour
- 1 cup milk chocolate chips
- ½ cup marshmallow fluff
- 1 cup mini marshmallows
Instructions
- Preheat oven to 325°F. Line an 8-by-8-inch baking pan with aluminum foil or parchment paper, leaving overhang on the sides. Spray with nonstick cooking spray; set pan aside.
- In a bowl, combine melted butter and graham cracker crumbs. Press into prepared pan. Set aside.
- In a large microwave-safe bowl, combine butter, sugar, cocoa, salt, and heat on high power to melt, about 45 seconds. Stop to stir, and heat in 10-second bursts until mixture has melted and can be stirred smooth (mine took 45 seconds + 15 seconds). Batter will be very granular.
- Add the vanilla, eggs, and stir vigorously until batter is thick, shiny, and well blended. Add the flour and stir until you cannot see it any longer. Fold in the chocolate chips. Pour half the batter into the prepared pan and spread evenly.
- Dollop half of the marshmallow fluff all over the batter and swirl slightly with a knife. Spread the remaining batter carefully over the marshmallow fluff. Repeat with the remaining marshmallow on top of the brownie batter. With a knife, carefully swirl the marshmallow fluff slightly into the batter. Don’t swirl too much!
- Bake until a toothpick in the center emerges slightly moist with batter, about 25 minutes. Increase oven temperature to 375°F. Top with mini marshmallows and bake for another 3-5 minutes or until marshmallows are lightly browned on top.
- Cool brownies completely before cutting into 16 equal squares with a very sharp knife.
- Brownies will keep in an airtight container at room temperature or in the refrigerator for up to 1 week, or in the freezer for up to 3 months.

Real talk: The pictures of these brownies are making me drool. I can’t look at them anymore. I pinned several before even reading the post. Now I have to click away because I’m tempted to eat my computer.
These are insanely good looking! Love the crumbly graham cracker crust! YUM!
Oh no! I almost had a heart palpitation thinking of being away from the phone and internet for a whole week! Maybe I have a problem, haha! I hope the rest of your trip was great though! These smores brownies look amazing and gooey and delicious!

These are just, I don’t even have any words…they sound and look absolutely amazing! Pinned!
Thanks so much for the kind words and the pin, Phi! :)
I don’t have marshmallow fluff…can I use mini marshmallows? Will they melt into the batter also?
You can either skip the fluff (you still have the marshmallows on top) or mix mini marshmallows into the batter, but sometimes marshmallows will dissolve into the brownie batter!
These don’t just look like the best brownies every, they look like they will literally cure your illness. So much ooey gooey deliciousness! Hope you’re feeling better!
Thanks Nora! Definitely all better, thank goodness!
1-omg you poor thing! stolen phone! sick! You totally deserve more brownies!
2-um.yeah.best use of s’mores possible. I want the entire pan.
Uhm, there are no words to describe the awesomeness of what I’m looking at right now. This is insanely amazing Rachel!!! Like, give me the whole freaking batch of these right now! …please?! Hahaha making these for sure!
Did you make any modifications to the recipe? Your pics show chips on the top and I only see one layer of marshmallow?
Hi Elizabeth. Nope – the recipe is photographed as written. The marshmallow fluff sort of melts into the brownie layer so it isn’t visible in the pictures, and I mentioned in the post that I sprinkled a few extra chocolate chips on top. They were added mostly for aesthetic appeal, since there are already chips in the batter!
These look so good my jaw is literally dropping! How ooey gooey that marshmallow looks!
We love your recipes. Are you interested in becoming a Chicory recipe partner?
How long do I bake it if I double the recipe and put it in a 9x13inch pan?
Hi Sara. It will probably take closer to 35 or 40 minutes – I would start checking them around 30-ish minutes! Enjoy.
I had all the ingredients except for the milk chocolate chips, ended up using semi- sweet chips and it was delicious! Thanks for this recipe! I will definitely be making this again
So glad you’re loving them, Michele! Thanks for the feedback :)
I had these in the oven for literally almost an hour and the center still did not cook. I followed the recipe to a T ♀️
Sorry you’re having issues Caitlyn – are you sure nothing was changed about the recipe? Is your oven running at the right temperature?
These were not good. The Graham cracker crust added nothing and the brownie was way too dense.
Sorry you didn’t enjoy these, Whitney. These are described as a super fudgy brownie, not a cakey one, so I think a denser brownie is to be expected.
