Why Make This Smores Brownies with Graham Cracker Crust

You should make this recipe because it offers the ultimate textural experience. Most brownies are just soft, but this version adds a distinct crunch from the Graham cracker base and a sticky, cloud-like finish from the toasted marshmallows. It is a crowd-pleaser that looks impressive but uses simple pantry staples. Plus, it is much less messy than traditional s’mores since everything is contained in a neat, sliceable square. If you love deep chocolate flavors paired with buttery notes, this is the only brownie recipe you will ever need.

Ingredients

• 1 1/2 cups Graham cracker crumbs (about 10-12 full sheets)
• 6 tablespoons unsalted butter, melted
• 2 tablespoons granulated sugar (for crust)
• 1/2 cup unsalted butter, melted and slightly cooled (for brownies)
• 1 cup granulated sugar (for brownies)
• 2 large eggs, room temperature
• 1 teaspoon vanilla extract
• 1/3 cup unsweetened cocoa powder
• 1/2 cup all-purpose flour
• 1/4 teaspoon salt
• 1/2 cup semi-sweet chocolate chips
• 3 cups miniature marshmallows
• 2 Graham crackers, roughly broken into pieces for topping

Directions

Step 1: Preparation and Oven Setup

Preheat your oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper, leaving an overhang on two sides to easily lift the brownies out later. Lightly grease the parchment with non-stick cooking spray or a little butter.

Step 2: Create the Graham Cracker Crust

In a medium bowl, combine the Graham cracker crumbs, 6 tablespoons of melted butter, and 2 tablespoons of sugar. Stir until the mixture looks like wet sand. Press the mixture firmly and evenly into the bottom of the prepared baking pan. Bake the crust for 8 minutes, then remove it from the oven and set it aside while you prepare the brownie batter.

Step 3: Mix the Brownie Batter

In a large mixing bowl, whisk together the 1/2 cup of melted butter and 1 cup of sugar until well combined. Add the eggs and vanilla extract, whisking vigorously until the mixture is smooth and slightly pale. Sift in the cocoa powder, flour, and salt. Fold the dry ingredients into the wet ingredients using a spatula until just combined. Be careful not to overmix. Fold in the chocolate chips.

Step 4: Bake the Brownie Layer

Pour the brownie batter over the pre-baked Graham cracker crust and spread it into an even layer with a spatula. Place the pan back in the oven and bake for 22–25 minutes. The center should be set but still slightly soft to ensure a fudgy texture. Do not overbake at this stage, as the brownies will go back in the oven briefly.

Step 5: Add the Topping and Toast

Remove the pan from the oven and immediately sprinkle the miniature marshmallows and broken Graham cracker pieces over the top. Switch your oven to the broiler setting. Place the pan back in the oven on the top rack for 1–2 minutes. Watch closely! The marshmallows will brown and puff up very quickly. Once they are golden brown and toasted, remove the pan from the oven.

Step 6: Cool and Slice

Allow the brownies to cool completely in the pan on a wire rack for at least 1 hour. This allows the layers to set so you get clean cuts. Use the parchment paper overhang to lift the brownies out of the pan. Use a hot, sharp knife to slice them into 16 squares, wiping the knife between each cut to prevent the marshmallows from sticking.

Expert Tips for Perfect Smores Brownies with Graham Cracker Crust

• Pack the crust tight: Use the bottom of a measuring cup to press the Graham cracker crumbs firmly into the pan. This prevents the crust from crumbling when you slice the brownies.
• Watch the broiler: Marshmallows can go from perfectly toasted to burnt in seconds. Stay by the oven door the entire time they are under the broiler.
• Use room temperature eggs: Room temperature eggs incorporate more easily into the batter, resulting in a better rise and smoother texture.
• Clean cuts: If the marshmallows are too sticky to cut, lightly grease your knife with cooking spray or dip it in hot water and wipe it dry between slices.
• Don’t overbake: The brownies continue to cook slightly as they cool. Pull them out when a toothpick inserted in the center comes out with a few moist crumbs.

Delicious Variations

• Peanut Butter S’mores: Add a 1/4 cup swirl of creamy peanut butter into the brownie batter before baking for a salty-sweet twist.
• Dark Chocolate: Use dark cocoa powder and dark chocolate chunks instead of semi-sweet chips for a richer, more intense flavor.
• Extra Crunch: Sprinkle chopped pecans or walnuts over the Graham cracker crust before pouring the brownie batter.
• Salted Caramel: Drizzle salted caramel sauce over the toasted marshmallows right before serving.
• Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free baking blend and use gluten-free Graham crackers.

Frequently Asked Questions

Can I use a box brownie mix instead of making them from scratch?
Yes, you can use a standard box mix. Simply follow the box instructions for the batter and apply the Graham cracker crust and marshmallow topping steps as directed in this recipe.

How do I store these brownies?
Store the brownies in an airtight container at room temperature for up to 3 days. Do not refrigerate them, as this can make the crust soggy and the marshmallows tough.

Can I freeze Smores Brownies?
You can freeze the brownie and crust layers, but marshmallows do not freeze and thaw well. If you plan to freeze them, leave the marshmallows off, freeze the base, and add the marshmallows fresh under the broiler when you are ready to eat.

What if I don’t have miniature marshmallows?
You can use large marshmallows. Just cut them in half with kitchen shears so they lay flat and cover the surface area of the brownies evenly.

My marshmallows aren’t browning evenly, what can I do?
If your oven broiler has hot spots, rotate the pan halfway through the browning process. Alternatively, you can use a kitchen blowtorch to manually toast specific areas for a perfect finish.
