Gathering these simple yet essential ingredients is the first delightful step toward creating your S’mores Brownies Recipe. Each item plays a vital role in building the perfect storm of texture and flavor — from the crispy graham crackers adding crunch, to the velvety cocoa and chocolate layers, all balanced by a touch of salt and sweetness.

Graham crackers (5 pieces): These provide the classic s’mores crunch and a subtle honeyed flavor foundation.
Semisweet chocolate (85 g): Melts smoothly with oil to imbue the batter with deep, rich chocolate notes.
Neutral oil (150 g): Keeps the brownies moist and tender without overpowering other flavors.
Granulated sugar (200 g): Adds sweetness and helps create a lovely crust on top.
Brown sugar (142 g): Brings warmth and a slight molasses taste that enhances the chocolate.
Salt (½ teaspoon): Balances sweetness and intensifies chocolate flavor.
Eggs (3, room temperature): Provide structure and richness for that perfect fudgy texture.
Vanilla extract (2 teaspoons): Lends a fragrant note that lifts the chocolate and marshmallow flavors.
All-purpose flour (120 g): The backbone that holds the brownies together with just the right density.
Dutch process cocoa powder (84 g): Offers an intense chocolate flavor and rich color.
Milk chocolate (140 g, for mixing in batter): Creates melty pockets of creamy sweetness throughout the brownies.
Large marshmallows (36 pieces): The crowning glory that toast to golden perfection on top, mimicking campfire s’mores.

How to Make S’mores Brownies Recipe

Step 1: Prepare Your Pan and Graham Cracker Base

Start by setting your oven to 350 degrees Fahrenheit and lining an 8-inch square pan with parchment paper to keep the brownies from sticking. Then, carefully arrange the 5 graham crackers in the bottom of the pan, forming a single layer. This acts like a crunchy, sweet ‘crust’ that will beautifully support the brownie layers atop it.

Step 2: Melt Chocolate and Oil

Combine the semisweet chocolate and neutral oil in a small bowl. Heat the mixture in short 30-second bursts in the microwave, stirring in between, until it melts into a smooth, glossy liquid. Setting this aside allows it to cool just a bit before mixing it in later.

Step 3: Whisk Sugars, Eggs, and Vanilla

Grab a large bowl and whisk together the granulated sugar, brown sugar, salt, eggs, and vanilla extract using an electric hand mixer set to high speed. This mix should rise and become pale and fluffy, roughly doubling in size after about 5 to 6 minutes. This creates a lightness that helps your brownies stay fudgy yet just right.

Step 4: Incorporate the Chocolate Mixture

Keeping your electric mixer on low speed, slowly pour the melted chocolate and oil blend into the sugar and egg mixture. This gradual mixing ensures a smooth integration, giving the batter its signature rich chocolate base.

Step 5: Add Dry Ingredients and Milk Chocolate

Now it’s time to add the flour and Dutch process cocoa powder. Mix gently on low speed until mostly combined—be careful not to overmix, which can toughen brownies. Then, fold in the milk chocolate chunks by hand until they’re evenly scattered throughout the batter, promising ooey-gooey chocolate bits in every bite.

Step 6: Pour and Bake

Pour the luscious brownie batter carefully over the graham cracker base you set earlier in the pan, spreading it evenly. Bake in the preheated oven for about 35 minutes. Once baked, let the brownies cool completely in the pan—this takes about an hour and is crucial for the brownies to set properly before the next step.

Step 7: Toast the Marshmallows

After cooling, arrange large marshmallows neatly on top of the brownies. Return the pan to the oven and bake for an additional 5 to 8 minutes, just until the marshmallows puff up and turn a beautiful golden brown. This final touch melts the marshmallows just enough for that irresistible s’mores effect without burning.

Step 8: Slice and Enjoy

Remove the pan from the oven and let the brownies cool slightly before lifting them out using the parchment paper edges. Cut into 9 generous squares and prepare yourself for one of the most heavenly, chocolate-marshmallow experiences.

Garnishes

These brownies stand beautifully on their own, but you can elevate the presentation by adding a sprinkle of crushed graham crackers or a drizzle of melted chocolate on top. A few mini marshmallows or a sprinkle of sea salt can also add texture and contrast.

Side Dishes

Serve your S’mores Brownies Recipe with a scoop of vanilla bean ice cream or a dollop of whipped cream to balance the richness. Fresh berries, like raspberries or strawberries, bring a bright, tangy complement. For a cozy gathering, pair them with a warm mug of hot cocoa or coffee.

Creative Ways to Present

Slice the brownies into bite-sized pieces and skewer them with small sticks for a fun party treat. You could also make individual brownie cups by baking the batter in muffin tins lined with graham crackers. Another idea is to layer the S’mores Brownies Recipe in a trifle dish with whipped cream and chocolate shards for a show-stopping dessert.

Make Ahead and Storage

Storing Leftovers

Leftover S’mores Brownies can be stored in an airtight container at room temperature for up to 3 days. If your kitchen is particularly warm, you might want to refrigerate them to prevent melting, though this can slightly change the texture.

Freezing

These brownies freeze beautifully. Wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag or container. They’ll keep well for up to 3 months. When ready to enjoy, thaw at room temperature for a couple of hours or overnight in the fridge.

Reheating

If you like your brownies warm, gently reheat them in the oven at 300 degrees Fahrenheit for about 10 minutes or pop them in the microwave for 15-20 seconds. This warms the marshmallows and chocolate for a gooier, melty sensation reminiscent of freshly toasted s’mores.

FAQs

Can I use regular cocoa powder instead of Dutch process in this S’mores Brownies Recipe?

Yes, you can substitute regular cocoa powder if that’s what you have, but Dutch process cocoa tends to give a smoother, less acidic chocolate flavor which pairs beautifully with the marshmallow and graham cracker components.

What type of chocolate works best in the batter?

Milk chocolate is recommended for mixing into the batter because it melts smoothly and adds a creamy sweetness that contrasts the deeper semisweet chocolate base. However, feel free to try bittersweet or dark chocolate chunks for a richer bite.

How do I avoid burning the marshmallows while toasting?

Keep a close eye on the marshmallows during the final baking step—the toasting happens quickly and can go from golden to burnt fast. If your oven has a broil setting, you can use it for just 1-2 minutes but watch carefully to prevent charring.

Can I make this recipe gluten-free?

Absolutely! Substitute the all-purpose flour with a gluten-free baking blend that measures cup-for-cup. Make sure to check that your cocoa powder and other ingredients are gluten-free as well for the best results.

Is it necessary to beat the egg and sugar mixture until doubled in size?

Yes, beating the mixture until fluffy incorporates air that contributes to the structure and fudgy texture of the brownies. Skipping this step might result in denser brownies that don’t quite have the same light yet chewy balance.

Final Thoughts

I can’t recommend this S’mores Brownies Recipe enough for those moments when you want to indulge in a dessert that is both comforting and delightfully nostalgic. The combination of crisp graham crackers, deeply chocolatey brownie, and luscious marshmallows makes every bite feel like a celebration.
