Ingredients You’ll Need

The magic of this S’mores Brownies Recipe lies in a well-balanced combo of simple, classic baking ingredients and those iconic campfire staples. I always recommend fresh eggs and good-quality cocoa powder for that rich chocolaty taste that holds up against the marshmallow sweetness.

• Graham crackers: These create the crunchy base and crunchy topping that scream “s’mores.” Be sure to use the plain variety, not the honey ones, to get that authentic flavor.
• Unsalted butter: Butter is key to richness—using unsalted lets you control the salt balance.
• Semi-sweet chocolate chips: I love semi-sweet as it balances sweetness without being too sugary.
• Granulated sugar: Adds that necessary sweetness and a little structure to the batter.
• Large eggs: Bring them to room temperature so they mix in smoothly without scrambling your batter.
• Cocoa powder: Unsweetened works best here for that deep chocolate flavor; Dutch-processed or natural cocoa can be used.
• Vanilla extract: A splash brightens the whole batter and adds depth.
• Salt: Just a pinch to balance the sweetness and enhance flavors.
• All-purpose flour: Provides structure without weighing the brownies down.
• Mini marshmallows: These little guys melt beautifully on top for that authentic, gooey s’mores effect.
• Hershey’s chocolate bar: The classic s’mores chocolate, chopped or broken into pieces to sprinkle on.
• Additional crushed graham cracker: For sprinkling on top to add a little extra crunch and rustic look.

Variations

I’m all about customizing recipes to suit what you have on hand or what you’re craving. With this S’mores Brownies Recipe, I’ve experimented a few ways, and you’ll find these tweaks really fun and sometimes game-changing.

• Use box brownie mix: On busy days, I love swapping the homemade batter for a trusty boxed mix—just follow the package instructions and layer with s’mores goodies the same way.
• Marshmallow fluff topping: Sometimes, I replace mini marshmallows with a generous layer of marshmallow fluff spread to make it extra gooey and smooth.
• Dairy-free version: Swap butter for coconut oil and use dairy-free chocolate chips to make these suitable for lactose intolerance.
• Nutty addition: Adding chopped toasted pecans or walnuts on top gives a delightful crunch and nuttiness that pairs surprisingly well.

How to Make S’mores Brownies Recipe

Step 1: Prep Your Pan and Graham Cracker Base

Start by preheating your oven to 350°F (177°C). Line an 8 x 8-inch metal baking pan with parchment paper, leaving enough overhang on two sides so you can easily lift the brownies out after baking. Then, press the graham cracker sheets tightly across the bottom. Feel free to break some to fill any gaps—it’s okay if it’s not perfect! The crackers act like a crunchy crust and add that essential s’mores foundation.

Step 2: Make the Chocolate Butter Mixture

In a microwave-safe bowl, combine your butter and semi-sweet chocolate chips. Heat in 30-second increments, stirring each time, until everything is melted and smooth. I like to be patient here because overheating can cause the chocolate to seize or get grainy—so go slow and stir well!

Step 3: Mix Sugar and Eggs for a Velvety Batter

Add the sugar to your chocolate mixture and stir just enough to barely combine. Pop it back in the microwave for one more minute to help the sugar dissolve better. Then stir thoroughly until the mixture is shiny and smooth. Let it cool a bit—warm, not hot is best—before whisking in the eggs. I usually whisk for about a minute until the batter looks glossy and ribbons when I lift the whisk—this means it’s aerated and ready.

Step 4: Fold in Dry Ingredients

Whisk in vanilla, cocoa powder, and salt until everything is uniform and glossy. Then add the flour, mixing just until the flour disappears—be careful not to overmix or the brownies will turn out dense instead of fudgy.

Step 5: Bake the Brownie Base

Spoon the brownie batter evenly over the graham cracker layer in your pan. Use a flexible spatula to smooth the top gently. Bake for about 25 minutes—you want the brownies almost, but not fully baked here. This step sets the base so that when you add the s’mores toppings, they don’t sink.

Step 6: Add the S’mores Toppings and Finish Baking

Carefully remove the brownies from the oven and immediately sprinkle the mini marshmallows evenly on top, followed by the roughly crushed graham cracker, and finally broken pieces of Hershey’s chocolate bar. Return the pan to the oven for another 8–10 minutes while the marshmallows toast lightly and the chocolate melts into patches of gooey goodness.

Step 7: Cool and Serve

Once out of the oven, let the brownies cool in the pan for about an hour. This cooling time is key—it helps everything set nicely so you get clean cuts and oozy s’mores layers without a meltdown mess. Then use the parchment overhang to lift your brownies out and slice them into 16 squares to share (or keep all to yourself, no judgment here!).

How to Serve S’mores Brownies Recipe

Garnishes

I like to keep it simple and let the s’mores brownies speak for themselves, but for a pretty touch, sprinkle a little extra crushed graham cracker on top just before serving. Sometimes, I toss on a few whole mini marshmallows and scatter a few chocolate chips for visual appeal and a sprinkle of extra sweetness.

Side Dishes

This rich treat pairs beautifully with a tall glass of cold milk or a scoop of vanilla ice cream to balance the sweetness. On colder days, I even serve it alongside a mug of hot cocoa or coffee for the ultimate cozy combo.

Creative Ways to Present

For parties, I’ve served these brownies cut into bite-sized squares on a rustic wooden board with little skewers, making it easy for guests to grab and enjoy without getting sticky fingers. Another fun idea is layering individual brownie squares into clear jars with extra marshmallows and crushed graham crackers for a cute take-home treat.

Make Ahead and Storage

Storing Leftovers

Once your s’mores brownies have completely cooled to room temperature, store them in an airtight container at room temp. I usually keep them in my pantry or on a counter away from heat; they stay fresh for up to 5 days. Just be sure to layer parchment paper between slices if stacking to avoid sticking.

Freezing

I’ve had great success freezing baked and cooled brownies wrapped tightly in plastic wrap and foil. They keep well for up to 3 months. When I’m ready to enjoy, I thaw them overnight in the fridge before serving. The s’mores topping retains much of its texture, which is a win!

Reheating

If you want to warm up leftovers, pop a brownie square in the microwave for 10-15 seconds to soften the marshmallows and chocolate without melting everything too much. It’s like a fresh-out-of-the-oven moment in seconds!
