Creating the perfect S’mores Brownies Recipe is easier than you think, especially with a lineup of simple ingredients that each bring their own magic to the final result. From the crispy graham crackers to the luscious chocolate and fluffy marshmallows, every component plays a vital role in balancing flavor, texture, and that irresistible look.

Graham crackers (5 pieces): These form the crunchy, slightly sweet base that mimics the classic s’mores crust perfectly.
Semisweet chocolate (85 g): Melted with oil to create the rich chocolate foundation in the batter.
Neutral oil (150 g): Keeps the brownies moist and fudgy without overpowering flavors.
Granulated sugar (200 g): Adds sweetness while helping create a tender crumb.
Brown sugar (142 g): Infuses a subtle caramel note and adds to the chewy texture.
Salt (½ teaspoon): Enhances all the sweet flavors and balances the chocolate’s bitterness.
Eggs (3, room temperature): Provide structure and richness to the batter.
Vanilla extract (2 teaspoons): Lifts the flavor profile with warm, aromatic notes.
All-purpose flour (120 g): Gives the brownies their structure while keeping them tender.
Dutch process cocoa powder (84 g): Delivers a deep, smooth chocolate flavor and gorgeous color.
Milk chocolate (140 g): Stirred into the batter for melty pockets of mellow sweetness throughout.
Large marshmallows (36): The crowning glory, toasted to golden perfection on top.

How to Make S’mores Brownies Recipe

Step 1: Prepare Your Pan and Base

Start by preheating your oven to 350 degrees Fahrenheit and lining an 8-inch square pan with parchment paper for easy removal. Arrange the graham crackers evenly across the bottom of the pan, creating the crunchy base layer that is essential to the classic s’mores texture.

Step 2: Melt Chocolate and Oil

In a small bowl, combine the semisweet chocolate and neutral oil. Heat this mixture in the microwave in 30-second intervals, stirring between each, until fully melted and smooth. This glossy mixture is going to give the brownies their lush chocolate flavor and moist, tender crumb.

Step 3: Beat Sugars, Eggs, and Vanilla

Next, in a large bowl, place your granulated sugar, brown sugar, salt, eggs, and vanilla extract. Using an electric hand mixer, whip these ingredients on high speed for about 5 to 6 minutes. You want the mix to double in size and become light and fluffy, which creates that airy yet gooey brownie texture we’re aiming for.

Step 4: Incorporate Chocolate-Oil Mixture

With your mixer running at low speed, slowly pour in the melted chocolate and oil blend. This ensures the batter stays smooth and emulsifies perfectly without losing the volume you worked hard to build in the previous step.

Step 5: Add Dry Ingredients and Milk Chocolate

Now sift together the flour and Dutch process cocoa powder and add them gradually to your batter. Mix just until mostly combined on low speed—overmixing can make brownies tough. Then gently fold in the milk chocolate pieces so they’re evenly distributed, offering melty rich bites throughout.

Step 6: Assemble and Bake

Pour the thick, luscious brownie batter over the graham cracker base in your prepared pan and spread it out evenly. Bake it in the preheated oven for about 35 minutes. When it’s done, let the brownies cool completely in the pan for roughly one hour; this helps them set and makes cutting easier.

Step 7: Toast the Marshmallow Topping

Once fully cooled, top the brownies with large marshmallows, arranging them close together to cover the surface. Return the pan to the oven and bake for an additional 5 to 8 minutes. Watch closely as the marshmallows puff up and turn a warm golden brown—that toasted look and texture is what makes the S’mores Brownies Recipe so irresistible.

Step 8: Cut and Enjoy!

Remove the pan from the oven and allow the brownie to cool slightly so the marshmallow topping sets. Lift out the entire block using the parchment paper and cut into 9 generous squares. Serve fresh, and enjoy each gooey, chocolatey, crispy bite with a smile.

Garnishes

If you want to jazz up your S’mores Brownies Recipe even more, try sprinkling a few crushed graham crackers or mini marshmallows on top right after baking. A light drizzle of chocolate or caramel sauce can also add a delightful finishing touch without overshadowing the classic flavors.

Side Dishes

These brownies pair wonderfully with a scoop of vanilla ice cream, which cools the toasted marshmallow topping and adds creaminess. Fresh berries can also balance the sweetness with a burst of freshness, or pour a glass of cold milk for the ultimate comforting combo.

Creative Ways to Present

For a fun twist, try serving your S’mores Brownies Recipe as mini portable treats by cutting into bite-sized squares and placing each on a decorative mini cupcake liner. They also work great on dessert platters alongside other crowd-pleasers at parties or backyard gatherings.

Make Ahead and Storage

Storing Leftovers

Keep any leftover brownies in an airtight container at room temperature for up to three days. Make sure the marshmallow topping is completely cool and set before covering to prevent sticking or sogginess.

Freezing

If you want to make the S’mores Brownies Recipe in advance, you can freeze the baked and cooled brownies (without topping) wrapped tightly in plastic wrap and then foil for up to 2 months. Toast the marshmallows fresh after thawing for the best texture.

Reheating

To bring your brownies back to warm, soft perfection, gently microwave individual servings for about 15-20 seconds or heat in a conventional oven at 300 degrees Fahrenheit for 5-7 minutes. Add fresh marshmallows and toast them briefly under a broiler if desired.

FAQs

Can I use a different type of chocolate for this S’mores Brownies Recipe?

Absolutely! You can swap the semisweet or milk chocolate for dark chocolate or even white chocolate depending on your preference. Just be mindful that different chocolates vary in sweetness and melting points, which may slightly affect the texture.

What if I don’t have graham crackers?

If graham crackers aren’t available, digestive biscuits or even a crushed cookie base can work in a pinch. The flavor won’t be exactly the same, but it will still add a nice crunch and texture contrast.

Can I make this recipe gluten-free?

For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup. Be sure the cocoa powder and other ingredients don’t contain any gluten-derived additives.

Is it okay to use jarred marshmallow fluff instead of large marshmallows?

While marshmallow fluff has a delicious taste, it won’t toast the same way as whole marshmallows and won’t give you that classic golden top. Using large marshmallows is key for that signature toasted finish.

Can I prepare this recipe without an electric mixer?

You can whisk the sugar, eggs, and vanilla by hand, but it will take more effort and time to reach the light and fluffy texture that helps make these brownies so wonderful. An electric mixer just speeds up the process and gives you a better rise.
