I’m so excited to share these with you today! We all know that s’mores are the ultimate summertime snack. They’re perfect for hanging around fire and spending treasured time with friends and family, and they’re easy and messy enough for kids to LOVE! The traditional s’mores recipe is simple: Graham cracker, chocolate, and toasted marshmallows. And who am I to mess with tradition?? That’s why this s’mores brownies recipe has all the same elements: a buttery graham cracker crust, a fudge brownie layer, and a toasted marshmallow fluff topping that is so gooey and amazing!

There are lots of recipes for s’mores desserts out there, but these s’mores brownies are the BEST! They’re based on my triple-chocolate pecan brownie recipe and the graham cracker crust from my lemon icebox pie, two of my best-love recipes on this site! And because I’m all about the easy shortcuts to recipe perfection, the topping for these s’mores brownies is good old store-bought marshmallow fluff!

Ingredients

Here’s what you’ll need to make these amazing s’mores brownies:

  • graham cracker crumbs — to make this recipe even easier, I used the store-bought crumbs
  • salted butter – for both the graham cracker crust and the brownie batter
  • dark brown sugar – to add sweetness and caramely richness at the same time
  • granulated white sugar – adds more sweetness
  • vanilla extract – perfect complement to the chocolate flavor!
  • eggs – to give structure to the brownie layer
  • cocoa powder – the source of the brownies’ rich chocolate flavor!
  • all-purpose flour – adds a little softness to these fudgy brownies
  • salt – to bring out all these flavors and cut the sweetness a bit
  • semisweet chocolate chips – to add the unmistakeable chocolate layer that s’mores are known for!

Equipment

Once you’ve got your ingredients together, all you’ll need next is to gather your tools. I use a 9×9 baking pan for these brownies, but if you have a springform pan or a high-sided 8×8 pan, those could work too. Let me know in the comments below what you used!

I would also recommend aluminum foil to line your pan, and an offset spatula to spread your marshmallow fluff.

Tips for the best s’mores brownies

Adding Eggs

 This smores brownie recipe is based on my Triple-Chocolate Pecan Brownies, but only uses 2 eggs to make a fudgier, denser brownie layer and make a little extra space in the pan for our marshmallow layer.  If you prefer a texture that’s slightly more cakey, add in the third egg!

Also, as a quick and easy alternative to the brownie recipe altogether, you can choose to swap in your favorite brownie box mix, prepared according to the instructions on the package!

Spreading and slicing marshmallow fluff

I would suggest having a damp cloth on hand to wipe down your offset spatula each time you spread your marshmallow fluff.  It makes it easier to spread it neatly without getting it everywhere! And the same goes for when you slice your brownies to serve — be sure to wipe your knife with a damp cloth between each cut!

Broiler safety

Be sure to watch the pan constantly while using the broiler.  Marshmallow can easily catch fire, so place your pan on a center rack so that it’s far enough away from the heat source. Once you see the marshmallows start to smoke, it’s time to take them out! In general, use an abundance of caution anytime you’re using the broiler.

Ingredients

Graham Cracker Crust

Fudge Brownie Layer

Topping

  • 1 cup semisweet chocolate chips
  • 13 oz marshmallow fluffa.k.a. marshmallow creme

Instructions

Prepare Graham Cracker Crust

  • Line the bottom and all sides of a 9×9 baking pan with heavy-duty aluminum foil, and spray lightly with cooking spray.
  • Combine graham cracker crumbs, melted butter, and sugar in a bowl. Stir well to coat.
  • Press crust mixture into the bottom of the prepared pan and set aside.

Brownie Layer

  • Preheat oven to 350°F.
  • Whisk together melted butter, eggs, sugars, and vanilla until smooth.
  • Sift in cocoa powder, flour, and salt and fold into wet ingredients until just combined.
  • Spread batter onto graham cracker crust in pan and smooth the top.
  • Bake for 25-30 minutes or until center is set.
  • Just after removing pan from the oven, add chocolate chips to the top and allow to melt. Spread chocolate in an even layer over warm brownies. Let brownies cool completely (I place mine in the fridge to be sure they're cooled).

Marshmallow Layer

  • Spoon marshmallow fluff onto chocolate layer and spread evenly.
  • Broil on high for 2 minutes or until top of marshmallow fluff is lightly browned (see note). You can also toast the marshmallow layer with a culinary torch.
  • Chill again to firm up marshmallow layer, then cut and serve! Store leftovers in refrigerator.

Storage and Freezing: These brownies should be stored in the fridge to keep the marshmallow layer fluffy, and should be served chilled or at room temperature. I like them straight out of the fridge, because the marshmallow is still gooey but the chocolate layer is a little crunchy!
They can also be frozen in an airtight container for up to 2 months.

    • I would recommend waiting until the brownies are baked and then layering the fluff on top — marshmallow tends to melt when heated, which is why we spread the marshmallow fluff over chilled brownies and broil it for just a couple of minutes. I would imagine that if you layer the fluff under the brownie batter it would melt into the batter completely while baking. Hope this helps! Let me know if you try the recipe out! 🙂
