Seriously, this S’mores Browies recipe couldn’t be easier or more delicious and could not come at a better time!
ABOUT S’MORES BROWNIES
These brownies have rocked my brownie world! Seriously, they’ve knocked my creamy, didn’t-think-it-could-get-any-better Tahini Brownies off the top spot as my favorite brownies. I mean, s’mores are amazing and brownies are amazing, so…..you can imagine how over the top GOOD these are!
If you’re a fan of marshmallows and brownies, which since you’re reading this you most likely are, put my Chocolate Brownie Meringue Cake on your list! Also, peanut butter fans, I have this idea to combine this s’mores brownie recipe with my Peanut Butter Swirl Brownies! Think I should?!

S’MORES AND SUMMER
Sweet milk chocolate made all melty by a toasted marshmallow and sandwiched between two crunchy graham crackers! S’mores bring back so many summer memories for me! We always had, what to me as a child seemed like HUGE, raging bonfires every summer! My siblings, cousins, and all the neighborhood kids would be there to toast marshmallows.
My mom would be standing by with some Nestle Milk Chocolate Bar squares all ready on a graham cracker square. We’d plop our marshmallow on top of a graham cracker and she’d pull the marshmallow off the sticks by sticking another graham cracker on top!

WHAT’S INSIDE THESE BROWNIES?
These easy brownies are made with:
- a simple graham cracker crust
- thick, gooey brownies
- large and mini marshmallows on top
- flaky sea salt
- a graham cracker crumble
GRAHAM CRACKER CRUST
What are s’mores without graham crackers?! To keep these on the traditional s’mores side and to make them super easy, our crust is really just a single layer of sheets of graham crackers on the bottom of the pan. Easy, right?! And yummy.
The brownie batter simply gets poured over top of the graham cracker sheets! You’ll probably have to break a few graham crackers to get them to cover the bottom completely. It doesn’t have to be even/perfect, just try to break pieces to fit if need be.

GRAHAM CRACKER CRUMBLE
The top layer is a little more creative. Instead of sheets of graham crackers, these brownies have a crisp, delicious graham cracker crumble sprinkled on top!
To make the crumble, you just pulse a few graham crackers in a food processor til you have crumbs. I like to leave a few larger pieces just for a little variety in size. Stir the crumbs with some melted butter, brown sugar and cinnamon.

Spread the crumbs out on a baking sheet and bake toast them up in the oven. You’ll want to stir them around a couple of times as they bake. Once crisped up, allow them to cool on the baking sheet while you make the brownies.

EASY BROWNIE RECIPE
Now for these rich, fudgy brownies!
- First, lightly whisk or sift together the flour, unsweetened cocoa powder and salt in a medium bowl.
- Next, In a microwave safe bowl, melt the butter and chocolate together in 20 second intervals. Stir well after each interval. Continue until smooth and melted.
- Whisk the sugar into the melted butter and chocolate. Whisk in the eggs and vanilla and then stir in the dry ingredients until just combined.
- Pour the brownies over the graham crackers in the prepared pan and bake!


GOOEY, DELICIOUS TOPPINGS
While your brownies are baking, assemble the delicious toppings! You’ll want to have them ready to add to the top of the brownies as soon as they finish baking.
- flaky sea salt: Optional but adds a little salty to your brownies. Sprinkle it on lightly once the brownies come out of the oven.
- milk chocolate: I use Hershey’s Milk Chocolate because that’s what we always used when I was a kid. You can use any milk chocolate bar though. Just break it up into squares. You can place the squares into four rows of about 5 pieces of chocolate in each row.
- graham cracker crumble: Sprinkle some over the brownies.
- large marshmallows: Try to place them on top of the pieces of chocolate! You can also toss some cute mini marshmallows in between too!
- more graham cracker crumble: I like to sprinkle some more on top of the marshmallows

ADDING THE TOPPINGS
Once you’ve topped your brownies with the milk chocolate, large marshmallows, graham cracker crumbs and optional sea salt and mini marshmallows, return the brownies to the oven for just a few minutes. This will allow the marshmallows to heat and expand and the chocolate to melt.
TOASTING THE MARSHMALLOWS
After the brownies have been in the oven for a few minutes with the chocolate and marshmallows, remove them from heat. The last step is toasting the marshmallows. You can toast the marshmallows by using kitchen blow torch or the broiler. They’ll toast up quickly both ways.
If using the broiler, be extra sure to wear oven mitts and be extra careful. The broiler is very hot. The marshmallows will toast up very quickly and will go from golden to burnt in a matter of seconds. Watch closely until the marshmallows are the color you want them to be and then quickly (and carefully) remove them from the oven.


HOW TO CUT THE BROWNIES
Remove brownies from oven and let them cool in the pan. Use the parchment paper to lift the brownies out of the pan. The marshmallows will stick to the knife a bit, so it helps to run your knife under hot water and wipe it clean after each slice.
To cut into 16 squares, cut the brownies in half and cut each half in half. Rotate the pan and continue cutting until you have 16 squares.


What can be better than two of the best desserts combined into one amazing treat?! Just like classic s’mores, these S’mores Brownies are gooey, chocolatey and fun to eat. Bonus, their thick brownie center makes them even more chocolatey and decadent classic s’mores and no bon fire required!

Ingredients
FOR THE GRAHAM CRACKER CRUMBLE
- 3 sheets (1 1/2 ounces) graham crackers, crumbled
- 2 1/2 tablespoons unsalted butter, melted
- 1/3 cup brown sugar
- 1/8 teaspoon cinnamon
- pinch of salt
FOR THE BROWNIES
- 1/2 cup unsalted butter, melted
- 1/2 cup semisweet chocolate, chopped, melted
- 1/2 cup light brown sugar
- 1/2 cup granulated sugar
- 1 3/4 teaspoons vanilla
- 2 eggs
- 1/4 cup unsweetened cocoa powder
- 3/4 cup flour
- 5 whole sheets graham crackers or enough to cover bottom of 9 x 9 inch pan
- 1/2 teaspoon salt
- 1 Hershey’s Chocolate Bar (100 grams), broken into squares
- flaky sea salt, for sprinkling (optional)
- 2 cups large marshmallows
- 1/2 cup mini marshmallows (optional)
Instructions
FOR THE GRAHAM CRACKER CRUMBLE
- Preheat oven to 350 F and line a baking sheet with parchment paper.
- Pulse graham crackers in a food processor to crumbs. Some larger pieces are okay.
- Combine the graham cracker crumbs with the rest of the ingredients and spread it evenly onto the prepared baking sheet. Bake 9-12 minutes, stirring occasionally, until lightly browned. Remove from oven and let cool.
FOR THE BROWNIES
1. Preheat the oven to 350 F. Line a 9 x 9″ square baking dish with parchment paper with enough parchment paper to create an overhang of at least two inches on two sides.
2. Arrange the graham crackers to create a single layer that covers the bottom of the prepared pan. In a medium sized bowl, whisk to combine the cocoa powder, flour, and salt. Set aside.
3. Melt the butter and semisweet chocolate together in a bowl in the microwave. Microwave in 20 second intervals, stirring in between until melted. Add the sugar and whisk til combined. Add the eggs followed by the vanilla and whisk until smooth. Stir in the dry ingredients until just combined, being careful not to overmix. Pour the batter over the graham crackers in the baking dish.
4. Bake for 25 to 30 minutes or until a toothpick comes out clean or almost clean when inserted in the middle of the brownies. Remove from the oven and immediately sprinkle a little flaky sea salt on top of the brownies. Sprinkle some graham cracker crumbs over top. Evenly arrange the Hershey bar pieces on top of the brownies then place the large marshmallows evenly on top of the chocolate. Scatter the mini marshmallows then sprinkle more graham cracker crumbs on top of the chocolate and marshmallows.
5. Return pan to the oven for another 3-4 minutes until the marshmallows have started to puff up and the chocolate has melted. Remove brownies from the oven and carefully, wearing oven mitts, set a rack 8 inches from the heat, in the top third of the oven. Preheat the broiler to low and broil the brownies for up to 30 seconds, just long enough to achieve the color you want on the marshmallows. Watch carefully because they toast up quickly and can burn just as quickly. Remove from the oven and let the brownies cool in the pan for about 30 minutes.
6. Lift the brownies out of the pan using the parchment paper. Cut into squares.

Natalie blows me away with every single recipe and this is no exception! I’ve made a handful of different s’mores brownie recipes before and what sets these apart are 3 things: that incredible graham cracker crumble, along with the extra melty hersheys bar and you can’t forget the flaky sea salt! Highly highly recommend 👏🏼 100/10!!
