What Are S’mores Brownies?

The Origins of S’mores and Their Modern Twist in Brownies

The s’more—short for “some more”—originated as a simple campfire snack made from graham crackers, chocolate, and fire-roasted marshmallows. Over the years, this treat evolved from a camping staple into a bakery classic. Enter: S’mores Brownies.

Unlike regular brownies, these layered delights add texture and contrast with crunchy graham crackers and fluffy marshmallows. They offer a nostalgic bite of summer, but with a richer chocolate base. The fusion feels rustic and gourmet at the same time—a dessert that sparks joy in both kids and adults.

What Makes S’mores Brownies Unique Compared to Traditional Brownies?

What sets S’mores Brownies apart is the layered texture experience. At the base is often a crushed graham cracker crust, followed by a thick layer of gooey brownie batter. After baking partially, marshmallows are added on top and toasted to perfection.

The result? A triple-layer bar with a satisfying crunch, melt-in-your-mouth middle, and lightly caramelized top.

Essential Ingredients for S’mores Brownies

Key Ingredients You Can’t Skip (Marshmallows, Graham Crackers, and Chocolate)

Creating the perfect S’mores Brownies starts with using the right ingredients—each one plays a vital role in building those iconic flavors and textures.

1. Graham Crackers:
This is the crust that holds everything together and provides that signature crunch. Use finely crushed graham crackers mixed with melted butter and a bit of sugar to form the bottom layer. You can press this mixture into the pan to form a sturdy base before adding the brownie batter.

2. Chocolate Brownie Layer:
This middle layer brings the richness. Use a good-quality dark or semi-sweet chocolate along with cocoa powder for that deep fudgy taste. You’ll need:

• Unsalted butter
• Brown and white sugar
• Eggs (room temp)
• Vanilla extract
• All-purpose flour
• Baking powder
• Cocoa powder or melted chocolate

The brownie should be thick and slightly underbaked to keep it moist.

3. Marshmallows:
The final, crowning glory. Large marshmallows are best for a dramatic top, but you can also use mini ones for more even melting. For that classic toasted finish, pop the brownies under the broiler for 2–3 minutes until golden brown and slightly crispy.

How to Make the Perfect S’mores Brownies

Step-by-Step Process for a Gooey, Chocolatey Center

Making S’mores Brownies from scratch isn’t hard—but nailing that gooey center takes a bit of baking finesse. Here’s how to get it right every time:

Step 1: Prepare the Crust

• Preheat your oven to 350°F (175°C).
• Line an 8×8 baking pan with parchment paper.
• Combine 1½ cups of crushed graham crackers with 6 tablespoons of melted butter and 2 tablespoons of brown sugar, mixing until evenly moistened.
• Press the mixture firmly into the pan to form a smooth, even crust layer.
• Bake for 8–10 minutes, then cool slightly.

Step 2: Make the Brownie Layer

In a large bowl:

• Melt ½ cup unsalted butter with 1 cup semi-sweet chocolate chips.
• Stir in ¾ cup brown sugar and ¼ cup white sugar.
• Beat in 2 large eggs (one at a time), then add 1 teaspoon vanilla extract.
• Sift together ½ cup flour, ¼ cup cocoa powder, and a pinch of salt, then fold into wet mix.

Gently spread the batter over the graham cracker crust, taking care not to disturb the base.

Step 3: Bake and Layer Marshmallows

• Bake the brownies for 20–25 minutes—until the edges are set but the center is slightly jiggly.
• Remove from oven, top with a generous layer of marshmallows (large or mini).
• Broil for 1–2 minutes, watching closely, until marshmallows are golden and puffed.

Let them cool for at least 30 minutes before slicing to help the layers set.

Pro Tips for Achieving the Perfect Marshmallow Toast

• Use foil to shield edges: If your oven runs hot, protect the edges with foil during broiling to avoid burning.
• Keep your eyes on the broiler: Marshmallows can go from golden to burnt in seconds. Never walk away.
• Use a torch for more control: If you want a caramelized effect, a kitchen torch gives you better precision.
• Refrigerate before slicing: Pop the tray in the fridge for 20 minutes to make slicing easier without gooey mess.

Common Mistakes to Avoid When Baking S’mores Brownies

Even experienced bakers slip up when crafting multi-layered desserts like S’mores Brownies. To make sure yours turn out gooey, chewy, and photogenic, avoid these common errors.

Overbaking or Underbaking – How to Get the Texture Right

Timing is everything. Here’s how to strike the perfect balance between underbaked and overdone:

Avoid Overbaking:

• S’mores Brownies should be slightly underbaked when pulled from the oven. The remaining heat will continue to cook them slightly as they rest, ensuring a perfect texture.
• Insert a toothpick 1 inch from the edge. It should emerge with a few moist crumbs clinging to it—no wet batter.
• The center can be a little gooey—it firms up as it cools.

Avoid Underbaking:

• Raw batter in the center after 30 minutes? Your oven might be off. Always preheat and use an oven thermometer if needed.
• Let brownies cool completely before slicing. This allows them to set properly.

Layering Tips to Prevent Marshmallow Burn or Sinking

Marshmallows are delicate—they toast fast and can melt into the brownie layer if added too early.

Here’s how to layer like a pro:

For extra control, freeze your marshmallows for 5–10 minutes before placing them on hot brownies—this delays melting.

The Science of Chewy vs. Fudgy Brownies

Creating the perfect S’mores Brownies isn’t just about taste—it’s about texture. Whether you’re after a chewy bite or a rich, fudgy center, it’s all in the science. Here’s how to customize your brownies for your preferred texture.

How to Keep Brownies Chewy Every Time

Chewy brownies have structure, resistance, and a satisfying bite. If that’s your goal, consider these baking science secrets:

1. Use Brown Sugar: It retains moisture better than white sugar thanks to its molasses content. This results in chewier brownies.
2. Lower Fat-to-Flour Ratio: Chewy textures require more flour and slightly less butter.
3. Add One Extra Egg Yolk: This boosts chewiness and binding without making the brownies cakey.
4. Don’t Overmix: Stir just until combined. Overmixing whips in air, which leads to cake-like fluffiness.
5. Bake at a Slightly Lower Temp: 325°F (163°C) allows the center to cook evenly without drying out the edges.

Bonus tip: Let brownies cool fully in the pan to firm up naturally and retain their chewy edge.

Why Ingredients Like Eggs and Sugar Ratios Matter

Texture hinges on the egg-fat-sugar balance. Here’s a breakdown:

Chewy = Dense + Moist + Structured.
Fudgy = Rich + Gooey + Melt-in-the-mouth.

If you’re leaning fudgy for your S’mores Brownies, increase the chocolate-to-flour ratio and add a splash of espresso to intensify flavor.

Serving and Storing S’mores Brownies

Once you’ve baked your perfect batch of S’mores Brownies, don’t let poor storage or presentation ruin the experience. Serving style and storage method can make or break the texture, flavor, and wow factor.

Best Ways to Serve S’mores Brownies for Different Occasions

1. Warm & Gooey for Gatherings:
Serve brownies warm from the oven with a scoop of vanilla ice cream. The hot brownie melts the ice cream for an irresistible dessert.

2. Cut Into Bars for Parties:
Use a hot knife to cut clean squares. This makes them easy to grab at birthday parties or potlucks without the mess.

3. Garnish for Upscale Events:
Top with a drizzle of melted chocolate or salted caramel and a mini toasted marshmallow for gourmet presentation.

4. Layered in a Dessert Glass:
Cut cooled brownies into chunks and layer them in a glass with whipped cream and extra graham cracker crumbs. It becomes a brownie trifle—no plates needed!

How to Store for Maximum Freshness and Flavor

Proper storage helps maintain texture and prevents the marshmallows from hardening or going stale.

Short-Term (1–3 Days):

• Store in an airtight container at room temperature.
• Keep parchment paper between layers to prevent sticking.

Medium-Term (Up to 1 Week):

• Store in the fridge in a sealed container. Let them sit at room temp for 10–15 minutes before serving to restore the softness.

Long-Term (Freezer-Friendly):

• Wrap individual brownie squares in plastic wrap, then store them in a freezer-safe zip-top bag for long-term freshness.
• To reheat, microwave for 20–30 seconds or toast lightly in the oven for a fresh-out-the-pan feel.

Pro Tip: Avoid storing brownies uncovered. Marshmallows can harden quickly when exposed to air, altering texture and flavor.

Creative Variations of S’mores Brownies

S’mores Brownies are a dream on their own—but that doesn’t mean you can’t mix it up. Whether you want to add nutty flavors, spice things up for fall, or give them a gourmet twist, here’s how to elevate the classic into something unforgettable.

Peanut Butter, Caramel, and Nutty Add-ins for Flavor Boosts

Want to take your S’mores Brownies to the next level? Here are some rich, indulgent variations that pair beautifully with chocolate and marshmallow:

1. Peanut Butter Swirl:
Wrap individual brownie squares in plastic wrap, then store them in a freezer-safe zip-top bag for long-term freshness. Use a knife to swirl. The salty contrast enhances chocolate’s sweetness.

2. Caramel Drizzle:
Add a layer of soft caramel between the crust and brownie batter. Alternatively, drizzle caramel on top before serving.

3. Nutty Crunch:
Fold in chopped pecans, almonds, or walnuts to add texture and depth to the chocolate layer.

4. Cookie Crumble Top:
Top the marshmallows with crushed Oreos, peanut butter cookies, or even more graham crackers for a surprise crunch.

5. Espresso Kick:
Add 1 tsp of instant espresso powder to the batter for deeper chocolate flavor—a trick pro bakers swear by.

Expert Baking Tips and Hacks

Whether you’re a weekend baker or dessert fanatic, perfecting S’mores Brownies is all about fine-tuning technique. From ingredient handling to batter resting, these pro tips will help you level up your baking game.

Should You Let Your Brownie Batter Sit Before Baking?

Short answer: Yes—if you want deeper flavor and a crinkly top.

Allowing your brownie batter to rest for 20 to 30 minutes before baking offers real advantages: it enhances the texture, deepens the flavor, and can lead to a shinier, more crackly top.

1. Stronger Chocolate Taste:
   Letting the batter rest gives the flour time to hydrate and allows the cocoa powder to bloom, resulting in a richer, more developed flavor.
2. Shinier, Crackly Top:
   During the rest, sugar has more time to dissolve into the wet ingredients. This resting period helps form that signature shiny, crackled crust on top of the brownies once baked.
3. Improved Texture:
   Rested batter bakes more evenly, reducing the risk of raw centers or overcooked edges.

Pro Tip: Cover the bowl with plastic wrap and let it sit at room temp (not refrigerated).

Using Chocolate Chips vs. Chocolate Bars – Which Is Better?

When it comes to S’mores Brownies, the chocolate you use makes a huge difference.

Chocolate Chips:

• Easy to find, less expensive
• Form retains shape (great for pockets of melted chocolate)
• Often contain stabilizers that can impact melting quality

Chocolate Bars:

• Richer flavor and smoother melt
• Ideal for swirling or blending into batter
• Break into chunks for texture variation

What’s Best?
Use a mix: Melted chocolate bar in the batter + chocolate chips folded in for gooey bits throughout.
