Ingredients You’ll Need
These ingredients may seem simple, but each plays a crucial role in creating the perfect balance of crunchy, chewy, and melty texture in your S’mores Brownies Recipe. From the buttery crust to the rich cocoa powder, every component adds flavor and character to the final treat.

- Vegetable oil: Keeps the brownies moist and tender without weighing them down.

How to Make S’mores Brownies Recipe
Step 1: Prepare the Crust
Start by preheating your oven to 350°F and lining an 8×8 inch baking pan with parchment paper. Next, blend the graham crackers and sugar together in a food processor until the mixture is fine and sandy in texture. Stir in the melted butter until evenly combined, then press this mixture firmly into the bottom of the prepared pan. Bake for 15-20 minutes until golden and crisp. This crust sets the stage for that irresistible crunch in your S’mores Brownies Recipe.
Step 2: Make the Brownie Batter
While the crust is baking, whisk vegetable oil, sugar, eggs, and vanilla extract in a bowl until smooth. Add in the cocoa powder, flour, baking powder, and salt, stirring just until combined with no flour pockets. Fold in the bittersweet chocolate chips for delightful melty surprises. This mixture forms the rich, fudgy middle layer of the brownies.
Step 3: Assemble and Bake
Pour the brownie batter evenly over the cooled graham cracker crust. Be sure the crust is completely cool, so the batter doesn’t melt it. Bake the layered brownie for 30-40 minutes until the center is set but still moist. This baking step brings all those flavors together into the perfect chewy, chocolatey base for the marshmallows.
Step 4: Toast the Marshmallows
When the brownies are baked, it’s time for the magic touch. Scatter mini marshmallows generously over the warm brownies, then broil on high for about 2 minutes, keeping a close eye. You want the marshmallows to puff up and turn a beautiful golden brown without burning. This step tops your brownies with that signature gooey, toasted finish of the classic s’mores.
Step 5: Cool and Slice
Patience pays off with this recipe. Let the brownies cool for at least 30 minutes to allow the marshmallow topping to set slightly and the flavors to meld. Use a sharp knife to slice into 16 squares and get ready to enjoy the ultimate s’mores experience without the campfire fuss!
How to Serve S’mores Brownies Recipe
Garnishes
For an extra touch of charm, consider topping each brownie square with a small drizzle of melted chocolate or a sprinkle of crushed graham cracker crumbs. A light dusting of powdered sugar can also add a pretty contrast and a hint of sweetness. These simple garnishes elevate the presentation while reinforcing those signature flavors.
Side Dishes
Pair your S’mores Brownies Recipe with a scoop of vanilla ice cream or a dollop of whipped cream for a classic dessert combo that’s always a crowd-pleaser. Fresh berries or a drizzle of raspberry sauce can also balance out the sweetness and add a refreshing twist. Trust me, these little extras turn an already fantastic treat into a dessert party.
Creative Ways to Present
If you want to get playful, serve these brownies on a rustic wooden board with extra marshmallows and chocolate chips scattered around to mimic a campfire vibe. Or, stack smaller brownie squares and sandwich them with marshmallow fluff for a decadent brownie s’mores bite. The possibilities to impress family and friends with this S’mores Brownies Recipe are just endless.
Make Ahead and Storage
Storing Leftovers
Leftover brownies can be kept in an airtight container at room temperature for up to 3 days. This keeps the marshmallow topping soft and the brownie moist. If your kitchen is warm, storing them in the fridge can help maintain texture but may firm up the marshmallows slightly.
Freezing
You can freeze the brownies for longer storage by wrapping them tightly in plastic wrap and aluminum foil or placing them in a freezer-safe container. Freeze for up to 2 months. Thaw overnight at room temperature before serving to enjoy the gooey texture at its best.
Reheating
To bring the brownies back to warm, soft perfection, microwave individual squares for about 10-15 seconds or reheat in a low oven (300°F) for 5-7 minutes. Keep a watchful eye so the marshmallows don’t over-toast again. This quick reheat step mimics the fresh-out-of-the-oven indulgence beautifully.
FAQs
Can I use a different type of chocolate for the brownies?
Absolutely! While bittersweet chocolate chips add lovely richness, you can swap them for semisweet or even milk chocolate chips if you prefer a sweeter taste. Each will work wonderfully in this S’mores Brownies Recipe.
What if I don’t have a food processor for the crust?
No worries! You can place the graham crackers and sugar in a sealed plastic bag and crush them with a rolling pin until finely ground. Then mix with melted butter as usual for the crust.
Can I make this recipe gluten-free?
Yes! Simply substitute the all-purpose flour for a gluten-free all-purpose blend. The texture may vary slightly, but the brownies will still be delicious and give you that s’mores experience.
How do I prevent the marshmallows from burning when broiling?
Keep the oven rack a little farther from the broiler heat source and watch closely while broiling. It usually only takes about 2 minutes for the marshmallows to toast to a perfect golden color.
Can I double this recipe for a bigger batch?
Definitely! Just double all ingredients and bake in a 9×13 inch pan. Adjust baking times slightly, checking for doneness starting around 35 minutes. Doubling is a great way to serve a larger crowd with this beloved S’mores Brownies Recipe.

- This recipe can be made with vegan substitutes for eggs and butter to accommodate vegan diets.
