This recipe uses a handful of simple, everyday ingredients that work beautifully together to create layers of flavor and texture. Each ingredient adds something unique, from the buttery richness of the base to the sweet, crunchy, and gooey toppings that complete the magic.

Graham crackers: Seven sheets, carefully arranged to form a crunchy, nostalgic crust that holds everything together.

Light brown sugar: One and a half cups, giving a deep caramel flavor and fudgy sweetness.
Sugar: Half a cup, balancing the brown sugar with simple sweetness and aiding in a soft texture.
Eggs: Four large, at room temperature, providing structure and moisture for fudgy brownies.

Cocoa powder: One cup, for that intense, rich chocolate flavor that’s the heart of these brownies.
Flour: Two-thirds cup, just enough to give the brownies structure without drying them out.
Baking powder: Half a teaspoon, a slight lift to keep the brownies from getting too dense.
Salt: Half a teaspoon, to balance the sweetness and deepen the chocolate flavor.
Chocolate: Three and a half ounces, chopped for melty patches of rich chocolate goodness.

How to Make S’mores Brownies Recipe

Step 1: Prepare Your Pan and Graham Cracker Base

The first step is preheating your oven to 350 degrees Fahrenheit and lining a 9×9-inch pan with parchment paper for easy cleanup and neat squares later on. Next, place your graham crackers in the bottom of the pan, breaking them gently if needed to fit snugly without big gaps. This simple base is the crunchy contrast that makes these brownies unforgettable.

Step 2: Melt Butter and Combine Sugars

Using a medium saucepan over medium heat, melt the butter until smooth. Remove it from the heat and stir in the light brown sugar and granulated sugar. Let this mixture cool for about five minutes so it doesn’t scramble the eggs in the next step. This caramel-sweet mixture is what gives your brownies that rich, fudgy depth of flavor.

Step 3: Mix Wet Ingredients and Add Cocoa

Whisk the eggs and vanilla extract into the slightly cooled butter and sugar mixture until silky and smooth. Then, sift in the cocoa powder and mix it gently until combined, creating that deep chocolate base that promises coziness in every bite.

Step 4: Fold in Dry Ingredients

Now it’s time to fold in the flour, baking powder, and salt carefully so you maintain the batter’s fudgy texture. Mixing just until combined prevents over-developing gluten, keeping these brownies delightfully tender and moist.

Step 5: Bake the Brownies

Pour the luscious batter over the graham cracker base in your pan and smooth it out evenly. Pop this into the oven and bake for 30 minutes — patience is essential here because the perfect fudgy texture develops in that time.

Step 6: Add Chocolate Layer

When the brownies come out of the oven, immediately sprinkle the chopped chocolate across the top. Let the heat from the brownies soften the chocolate for about 3 to 5 minutes before using an offset spatula to spread it into a smooth, glossy layer. This step introduces an extra burst of melty chocolate that makes every bite irresistible.

Step 7: Top with Marshmallows and Brown

Arrange your marshmallows evenly across the chocolate layer in neat rows. Return the pan to the oven for 5 minutes to let the marshmallows start melting. For that classic toasted finish, use a kitchen torch to brown the tops, or place the pan on the top oven rack under the broiler for 15 to 30 seconds. Watch closely so they don’t burn!

Step 8: Cool and Cut

Allow the brownies to cool completely for 20 to 30 minutes so the layers set properly before cutting. Patience here pays off with clean squares loaded with gooey, crunchy, and fudgy layers that everyone will love.

Garnishes

For a lovely finishing touch, sprinkle a few crushed graham crackers or mini chocolate chips on top of the toasted marshmallows. A small drizzle of chocolate sauce or a dusting of cocoa powder adds an elegant hint that gives your s’mores brownies that extra special vibe.

Side Dishes

This decadent dessert pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream, balancing the rich chocolate and sweet marshmallow with a cool creaminess. Fresh berries also add a bright, tart contrast if you want a fresh pop of flavor alongside indulgent decadence.

Creative Ways to Present

Serve these brownies in rustic wooden boxes for an outdoor party vibe or plate them with colorful napkins for a fun family gathering. For a playful twist, try stacking smaller brownie squares into bite-sized towers or serve them with mini skewers for easy sharing and snacking—perfect for impressing friends and family.

Make Ahead and Storage

Storing Leftovers

Store any leftover brownies in an airtight container at room temperature for up to three days. Because of the marshmallow topping, it’s best not to refrigerate them or they may become sticky or hard. Keeping them covered helps maintain that gooey texture we all crave.

Freezing

If you want to save these for longer, freeze the brownies before adding the marshmallow topping or after they’ve been cut into squares in a single layer lined between parchment paper. Stored well in a sealable container or freezer bag, they’ll keep for up to two months and thaw quickly at room temperature.

Reheating

To bring your brownies back to their fresh-out-of-the-oven softness, warm them gently in a microwave in 10-second bursts or briefly in an oven at low heat. Be cautious with marshmallows—they melt quickly, so a light warm-up is all you need to revive their gooey charm.

FAQs

Can I use regular chocolate chips instead of chopped chocolate?

Absolutely! Regular chocolate chips will melt nicely too, but chopping a chocolate bar gives you bigger, melty pockets of chocolate that feel extra indulgent between bites.

What type of marshmallows work best for this recipe?

Mini marshmallows are ideal since they melt evenly and create that perfect toasted finish. If you only have large marshmallows, you can cut them into smaller pieces to spread out the coverage more evenly on top.

Can I make these gluten-free?

Yes! Simply swap the regular flour for a gluten-free baking flour blend. Just be sure it contains xanthan gum or another binding agent to keep the texture fudgy and tender.

How do I avoid the marshmallows from burning when broiling?

Keep a close eye on them and broil on a low rack setting for just 15 to 30 seconds. Marshmallows go from perfectly toasted to burnt very fast, so don’t walk away during this step!

Can I double this recipe for a larger batch?

You can double all the ingredients and bake in a 9×13-inch pan. Just watch the baking time and check periodically, as it might need a few extra minutes to cook all the way through due to the increased thickness.
