If you’re ready for the ultimate bake sale showstopper or a cozy treat that captures memories from summers by the campfire, these S’mores Brownies are absolutely calling your name! With a buttery graham cracker crust, rich homemade brownie center, and fluffy Swiss meringue toasted until it’s perfectly golden (all crowned with melty pockets of milk chocolate), this dessert transforms the nostalgic campfire classic into a crowd-pleasing, decadent tray bake. Every bite is a celebration of that toasted-marshmallow, chocolate-graham goodness you crave—no sticks or smoke required!

Ingredients You’ll Need

The magic of these S’mores Brownies lies in how a few simple ingredients come together, each playing a starring role. From sweet, crunchy graham cracker crumbs to a cloud-like meringue topping, don’t skip or skimp—every element adds to the layered flavor and dreamy texture.

Graham cracker crumbs: These form the sturdy and nostalgic base, delivering toasty flavor and a satisfying crunch.
Granulated sugar: Sweetens both the crust, the brownie, and the meringue, balancing the deep cocoa and creating that shiny top.
Unsalted butter (melted): Essential for richness—makes the crust and brownies melt-in-your-mouth tender but never greasy.
Unsweetened cocoa powder: Provides deep, authentic chocolate flavor—you want a good-quality, Dutch-process if possible.
Brown sugar: Brings a touch of caramel depth to the brownie batter, making it chewy and complex.
Large eggs (room temperature): Bind everything together, giving the brownies their fudgy texture.
Vanilla extract: Adds warmth and enhances the marshmallow notes—don’t leave it out!
All-purpose flour: Gives the brownies structure without making them cakey.
Salt: Just a pinch in all three layers punches up every flavor and keeps the sweetness from going overboard.
Egg whites (room temperature): The secret to that sky-high, glossy meringue, whipped to soft but sturdy peaks.
Cream of tartar: Helps stabilize the meringue for that classic marshmallow texture.
Milk chocolate bars (roughly chopped): Like the classic campfire treat—scatter them over the meringue for melty pools.
Graham crackers (roughly broken): For a fun, rustic finish and even more crunch. Optional but irresistible!

How to Make S’mores Brownies

Step 1: Build the Graham Cracker Crust

Start your S’mores Brownies with a solid foundation—mix graham cracker crumbs, a little granulated sugar, and melted butter until it looks like wet sand. Press this mixture firmly into a greased, parchment-lined 9×9-inch baking pan. Bake for 10 minutes at 350°F. This step creates a crust that won’t go soggy, so when you lift out the finished brownies later, every square stays intact with its crunchy graham base.

Step 2: Whip Up the Brownie Batter

While your crust bakes, whisk together unsweetened cocoa powder and melted butter until it’s glossy and lump-free. In a separate bowl, combine both sugars, eggs, and vanilla, then beat for a few minutes until the mixture is pale and creamy—this makes your brownies irresistible! Gently fold in the cocoa-butter mixture (take your time) for maximum fudginess, then finish by folding in flour and salt. The key: don’t over-mix, or you’ll lose that melt-in-your-mouth texture!

Step 3: Bake the Brownies

Pour the brownie batter evenly over your warm crust, smoothing the top for even baking. Slide the pan back into the oven and bake for 35 to 40 minutes. You’re looking for a toothpick inserted in the center to come out with moist crumbs (not wet batter)—the hallmark of perfectly baked S’mores Brownies. Let them cool completely in the pan on a wire rack.

Step 4: Make the Billowy Swiss Meringue

This step takes S’mores Brownies into campfire territory! Set a heatproof bowl over gently simmering water, then constantly whisk together egg whites, sugar, cream of tartar, and a pinch of salt until the mixture reads 155-160°F and all the sugar is dissolved. Beat with a stand or hand mixer until thick, glossy, and very stiff peaks form. Pat yourself on the back—you’re about to top brownies with actual cloud.

Step 5: Assemble and Torch!

Spoon your Swiss meringue in billowy heaps all over the cooled brownies, then sprinkle with generous bits of milk chocolate (and graham cracker shards if you’re feeling extra). Now for the best part: use a kitchen torch to toast the meringue until golden and lightly charred. Watch it closely—it goes from marshmallowy white to perfectly toasted in seconds! Slice, serve, and bask in the applause.

How to Serve S’mores Brownies

Garnishes

Go wild with your toppings! Extra chocolate shavings, a dusting of graham cracker crumbs, or even caramel drizzle makes each square irresistible. For special occasions, try mini marshmallows on top and torch them for double the gooey fun.

Side Dishes

S’mores Brownies are a decadent treat on their own, but they pair beautifully with a scoop of vanilla or coffee ice cream. Serve alongside fresh strawberries for a refreshing bite, or a cup of dark roast coffee to balance the sweetness.

Creative Ways to Present

Cut your S’mores Brownies into bite-sized cubes and serve them on skewers for a playful, party-ready platter—or stack squares into a tall tower for a dramatic centerpiece. You can even add a sparkler or two for a festive birthday or celebration vibe!

Make Ahead and Storage

Storing Leftovers

After the wow-factor of serving, cover any leftover S’mores Brownies tightly and keep them at room temperature for up to two days. For longer storage (and to keep that meringue from weeping), pop them in the fridge, where they’ll stay fresh for up to four more days.

Freezing

Yes, S’mores Brownies freeze like a dream! For best results, slice and wrap individual brownies in plastic wrap, then slip them into a zip-top freezer bag. Freeze for up to one month. When cravings hit, thaw overnight in the fridge and enjoy that same fudgy texture and toasted meringue topping.

Reheating

If you love your S’mores Brownies extra gooey, a quick zap in the microwave (about 10 seconds) softens the chocolate and brings back that fresh-from-the-campfire vibe. If you want to re-toast the meringue, use your kitchen torch or broil for just a few seconds (watch carefully!) to revive those golden peaks.

FAQs

Can I make S’mores Brownies without a kitchen torch?

Absolutely! Use your oven broiler on high, watching very closely, and rotate the pan for even browning. Just keep a careful eye—the meringue toasts in seconds.

Will store-bought marshmallow fluff work instead of Swiss meringue?

Marshmallow fluff is a shortcut you can use in a pinch, but homemade Swiss meringue gives unbeatable texture and stability. If you only have fluff, spread it over cooled brownies, then toast as desired.

Can I double the recipe for a bigger crowd?

Yes! Double the ingredients and bake in a 9×13-inch pan. You may need to slightly increase baking time, so check for doneness with a toothpick and keep an eye on the oven.

What’s the best way to cut S’mores Brownies cleanly?

For picture-perfect slices, dip your knife in hot water and wipe clean between cuts. This neat trick prevents the meringue from sticking and keeps each layer distinct and lovely.

Are S’mores Brownies gluten-free-friendly?

You can make these gluten-free easily by swapping in gluten-free graham crackers and a 1:1 gluten-free all-purpose flour. No one will even notice the difference!

Final Thoughts

These S’mores Brownies are pure joy, layering everything you love about ooey-gooey campfire s’mores into one easy, show-stopping bar. Whether you’re making them for friends, family, or just yourself (no judgment here!), I hope you give this recipe a spot in your baking rotation. Take a bite—you’ll see why these brownies disappear faster than you can say s’more!
