If you love the unforgettable trio of gooey marshmallows, creamy chocolate, and toasty graham crackers, these S’mores Brownies are calling your name! This irresistible treat blends the best of campfire s’mores with extra-fudgy brownies, creating a dessert that’s perfectly decadent—and shockingly easy to make.

Ingredients You’ll Need

It’s truly mind-blowing how a handful of pantry staples can transform into something so decadent! Each ingredient in these S’mores Brownies brings classic campfire flavor to your oven, while the ready-made mix keeps things simple and stress-free.

• Family size brownie mix (18.3 oz): The super moist, fudgey backbone for these brownies. Follow the box directions for “cakey” brownies for the perfect balance of chew and fluff.
• Eggs (2 large): Essential for structure, and help create those beautiful, tall brownie layers.
• Vegetable oil (⅓ cup): Gives the brownies a rich, tender crumb—use any neutral oil you love.
• Water (⅓ cup): Keeps the batter smooth and ensures a moist, luscious finish.
• Graham crackers (6, broken into pieces): These are the star of the s’mores show, adding a familiar crunch and that honeyed flavor we all adore.
• Miniature marshmallows (2 cups): Their puffiness and sticky sweetness transform these brownies into marshmallow magic after a few minutes in the oven.
• Snack-size Hershey’s Milk Chocolate Bars (12 bars, broken into squares): They melt perfectly, mimicking the classic s’mores chocolatey layer. Use as much or as little as your sweet tooth demands!

Variations

One of the best things about homemade S’mores Brownies is how easy it is to make them your own! Switch things up for different tastes or dietary preferences—these flexible treats are practically begging for a personal touch.

• Gluten-Free Version: Simply swap in your favorite gluten-free brownie mix and gluten-free graham crackers for all the classic flavors without the wheat.
• Peanut Butter S’mores: Add a swirl of peanut butter over the brownie batter before adding the toppings for a nutty, gooey upgrade.
• Dark Chocolate Twist: Trade out the milk chocolate bars for your favorite dark chocolate or even a mix of both to please grown-up taste buds.
• Extra Crunch: Sprinkle in nuts, toffee bits, or even pretzels along with (or instead of) graham crackers for new textures and flavors.

How to Make S’mores Brownies

Step 1: Prepare the Brownie Batter

Start by preheating your oven to 350°F (175°C). Grab a large mixing bowl and combine the brownie mix, eggs, oil, and water as instructed on the box for “cakey” brownies. Mix until everything is smooth and glossy—don’t overdo it! Pour the batter into a greased 13×9-inch pan, and spread it evenly to reach all the corners.

Step 2: Bake the Brownies

Bake for about 20 minutes, keeping a close eye on them. You want the brownies just shy of being fully baked—a toothpick inserted in the center should come out a bit wet or with a few moist crumbs. This is the secret to keeping that center fudgy and rich!

Step 3: Add the S’mores Toppings

Carefully remove the nearly-baked brownies from the oven and immediately sprinkle the graham cracker pieces and mini marshmallows all over the top. Scatter the Hershey’s chocolate squares on top of everything so they can melt and get that drool-worthy s’mores finish.

Step 4: Melt and Puff

Pop the pan back into the oven for about 5 more minutes. This final bake is short but mighty—just long enough for the marshmallows to puff up and toast, and for the chocolate squares to get glossy and soft.

Step 5: Slice and Serve

If you can’t wait (honestly, who could blame you?), spray a sharp knife with nonstick spray and slice the S’mores Brownies while they’re warm—respraying your knife as needed. Or, for picture-perfect bars, let them cool completely before cutting into 20 even squares.

How to Serve S’mores Brownies

Garnishes

A sprinkle of flaky sea salt or a drizzle of melted chocolate over the top gives these brownies an eye-catching finish and balances the sweetness. For extra marshmallow magic, torch a few mini marshmallows on top with a kitchen lighter just before serving.

Side Dishes

S’mores Brownies are rich, so pair them with fresh strawberries, raspberries, or even a tart berry sorbet to cut through the chocolatey goodness. A scoop of vanilla or coffee ice cream on the side makes them completely party-worthy!

Creative Ways to Present

Stack them on a rustic wooden board for a campfire-inspired dessert display, or serve individual bars in cupcake liners for easy grab-and-go bites. For parties, set up a topping bar so guests can customize each S’mores Brownie with sprinkles, nuts, or mini chocolate chips.

Make Ahead and Storage

Storing Leftovers

Keep any leftover brownies in the pan, covered tightly with plastic wrap or foil. They’ll stay fresh and moist for up to 3 days at room temperature, though the graham crackers will soften a bit as they soak up all that chocolate and marshmallow deliciousness.

Freezing

If you want to freeze your S’mores Brownies, wrap each bar tightly in plastic wrap and place in an airtight container or freezer bag. They’ll keep well for up to 2 months. For best texture, freeze before adding marshmallows and chocolate, then add those toppings and reheat just before serving.

Reheating

For that “just-baked” taste, zap a brownie in the microwave for 10–20 seconds. The marshmallows will fluff up and the chocolate will melt a little—pure bliss. If you’ve frozen them, thaw at room temp, then warm briefly before serving.
