S’mores Brownies Recipe

I simply adore this S’mores Brownies Recipe because it captures the magic of classic campfire s’mores in a rich, decadent brownie form. Every bite delivers that perfect harmony of crunchy graham cracker, deep chocolate, and gooey toasted marshmallow that feels like a cozy hug. I love how approachable it is to make, yet impressive enough to share with friends and family, turning any ordinary day into something special.

Why You’ll Love This S’mores Brownies Recipe

What really makes this recipe shine for me is the incredible flavor combination. The rich, nutty browned butter mixed with espresso-infused cocoa takes the chocolate to a whole new level of depth, and pairing that with the buttery crunch of graham crackers and the soft, toasted marshmallow topping creates an irresistible texture play. I find myself craving that contrast, and it’s exactly what makes these brownies unforgettable.

Another thing I love about this S’mores Brownies Recipe is how straightforward the process is. It’s a manageable recipe that doesn’t require any fancy equipment or complicated steps, just a bit of patience as you brown the butter and wait for the brownies to cool properly. I often make these for weekend gatherings or cozy nights in because they bring everyone together with their nostalgic charm and mouthwatering flavors. Plus, the finishing touch of quickly broiling marshmallows feels like a fun, almost theatrical moment that always impresses!

Ingredients You’ll Need

I keep the ingredient list simple and focused on essentials that each play a vital role in creating the layers of flavor and texture. From the crunchy graham crackers to the rich chocolate and fluffy marshmallows, every component is carefully chosen to build the perfect S’mores brownie experience.

• Graham cracker squares: These create the classic crispy base layer that brings that signature s’mores crunch.
• Dark or semi-sweet chocolate: Chopped finely to melt beautifully into the batter for that luscious chocolate richness.
• Natural cocoa powder: Adds depth and intensity with a slightly bitter undertone that balances the sweetness.
• Espresso powder: A tiny amount enhances the chocolate flavor without adding any coffee taste—trust me, it’s a game changer.
• Unsalted butter: Browned to nutty perfection, it adds complexity and moistness to the batter.
• Large eggs: At room temperature so they mix smoothly and help give the brownies structure.
• Granulated sugar: For classic sweetness and a bit of texture in the crumb.
• Brown sugar: Brings warmth and chewiness to the brownies with its molasses notes.
• All-purpose flour: Just enough to hold everything together without making the brownies cakey.
• Large marshmallows: Toasted on top for that irresistible gooey, browned finish that screams s’mores.

Directions

Step 1: Preheat your oven to 350°F and line a 9×9-inch pan with parchment paper on all sides, making sure to leave enough overhang to lift the brownies out later.

Step 2: Arrange a single layer of graham cracker squares at the bottom of the lined pan. You can break or cut some to fit snugly—it doesn’t have to be perfect, just a solid base.

Step 3: In a medium bowl, combine the chopped chocolate, natural cocoa powder, and espresso powder. Set this mixture aside while you brown the butter.

Step 4: Place the butter in a saucepan over medium heat. Stir occasionally as it melts, then watch carefully as the milk solids start to foam and turn golden brown. When you smell that delicious nutty aroma, remove the pan from the heat immediately to stop it from burning.

Step 5: Pour the browned butter into your chocolate mixture and stir until smooth and melted. Let this cool for 10 to 15 minutes so it doesn’t cook the eggs when combined.

Step 6: In a large bowl, whisk together the eggs, granulated sugar, and brown sugar until fully combined and slightly fluffy, about 2 minutes. Slowly drizzle in the cooled chocolate butter mixture while whisking continuously.

Step 7: Gently fold in the flour just until no streaks remain—you want to avoid overmixing to keep the brownies tender.

Step 8: Pour the batter over the graham cracker layer in the pan, spreading it evenly with an offset spatula or by gently shaking the pan to fill corners.

Step 9: Bake for 28 to 30 minutes, or until the edges are set and a toothpick inserted into the center comes out mostly clean but still a little moist. This ensures fudgy brownies.

Step 10: Immediately after baking, move your oven rack to the top position and switch on the broiler. Place a layer of marshmallows over the warm brownies and broil for 2 to 3 minutes until golden and toasted. Watch them closely as marshmallows can burn fast.

Step 11: Let the brownies cool on a wire rack for at least 30 minutes, then use the parchment overhang to carefully lift them out. For easier slicing, rub a bit of cooking oil on a knife to prevent the marshmallows from sticking.

Servings and Timing

This recipe yields about 16 generous brownie squares, perfect for sharing. Prep time is around 20 minutes, with about 30 minutes in the oven. Don’t forget to set aside at least 30 minutes for cooling and the marshmallow broiling step. Altogether, from start to finish, expect roughly 1 hour and 20 minutes. If you’re in a rush, refrigerating for an hour will speed up cooling without sacrificing texture.

How to Serve This S’mores Brownies Recipe

I love serving these brownies slightly warm so the marshmallow layer stays wonderfully gooey and soft while the brownie underneath is fudgy and rich. You can easily reheat individual squares in the microwave for 10 to 15 seconds if you want to revive that fresh-out-of-the-oven feeling. Pair them with a scoop of vanilla ice cream or a drizzle of caramel sauce to take indulgence to the next level.

For presentation, I like to plate these on rustic wooden boards or simple white plates to let the golden marshmallows and chocolatey layers really pop visually. Garnishing with a sprinkle of crushed graham crackers or a few toasted mini marshmallows adds a charming touch that guests always notice.

When it comes to beverages, I’m a big fan of pairing these brownies with a rich, dark coffee or a bold red wine like a Cabernet Sauvignon. If you prefer non-alcoholic drinks, a creamy hot chocolate or even an old-fashioned root beer float complements the flavors beautifully. These brownies are an absolute hit at holiday parties, family dinners, or even casual weekend gatherings where everyone wants to feel a bit nostalgic.

Variations

I enjoy playing around with this S’mores Brownies Recipe to customize it for different occasions or dietary needs. For example, substituting the all-purpose flour with gluten-free flour blends works perfectly for those who avoid gluten, without compromising texture. If you’re vegan, you can replace the butter with coconut oil and use flax eggs instead, although the marshmallow topping would then need a vegan substitute or be skipped altogether.

If you want to mix up the flavor, try adding chopped nuts like toasted pecans or walnuts into the batter for extra crunch and nutty depth. Some friends of mine love swapping the dark chocolate for milk chocolate chips to sweeten things up, which creates a more mellow but still satisfying brownie. You can also experiment with different toppings—sprinkling sea salt before baking or adding a drizzle of peanut butter after cooling adds new exciting layers of taste.

For an alternate cooking method, I’ve even tried making these in disposable foil pans on a grill set to indirect heat. It’s a great option for summer cookouts, just watch the broiling step carefully or use a kitchen torch to toast the marshmallows instead.

Storage and Reheating

Storing Leftovers

I usually store any leftover S’mores Brownies in an airtight container in the fridge to keep them fresh and maximize their fudgy texture. Make sure the container is sealed well to prevent the marshmallows from drying out or getting sticky. They will keep nicely for up to 4 days, though in my house, they rarely last that long!

Freezing

These brownies freeze beautifully if you want to save some for later. Wrap them tightly in plastic wrap and then place them in a freezer-safe container or zip-top bag. They’ll keep well for up to 3 months. When you’re ready to enjoy, thaw them in the fridge overnight and then bring them to room temperature before serving. Avoid freezing after marshmallow toasting if possible, as the marshmallow texture suffers a bit when thawed.

Reheating

The best way I’ve found to reheat these brownies is gently in a low oven set to 300°F for about 10 minutes. This method warms them through without drying out the brownies or melting the marshmallow topping excessively. Microwaving works too if you’re in a hurry, but only for short bursts (10-15 seconds) to avoid toughening the brownies or turning the marshmallows rubbery. My tip is to let them rest a little after reheating so the gooeyness settles perfectly.

FAQs

Can I use regular butter instead of browning it?

You can, but browning the butter adds a wonderful nutty flavor that really elevates the entire brownie. If you skip this step, you’ll still get tasty brownies but they won’t have the same depth of flavor that makes this S’mores Brownies Recipe special.

What if my oven doesn’t have a broiler?

No worries! You can use a kitchen torch to toast the marshmallows—just use quick, gentle passes across the marshmallow tops to avoid burning. Alternatively, placing the brownies close to the top heating element at high temperature for a very short time can achieve similar results but keep a close eye on them.

Can I make this recipe in a different pan size?

I recommend sticking to a 9×9-inch pan for the best thickness and baking times. If you use a larger pan, the brownies will be thinner and may bake faster, so reduce baking time accordingly. A smaller pan will yield thicker brownies but might need extra baking time to ensure doneness.

Is it possible to add more marshmallows inside the batter?

Absolutely! I’ve tried folding mini marshmallows into the batter before baking, which creates delightful pockets of melty sweetness. Just keep in mind they might melt and spread a bit, so the texture changes slightly, but it’s a delicious twist.

How do I prevent the marshmallows from sticking to the knife when slicing?

Great question! I find that rubbing a little cooking oil on an offset spatula or the knife blade before cutting helps a lot. This prevents the sticky marshmallow layer from clinging to your cutting tool and keeps your slices neat and clean.

Conclusion
