Ultimate 8-Inch Pan S’mores Brownies: Fudgy Chocolate, Toasted Marshmallow & Graham Cracker Perfection
There’s a reason some dessert combinations achieve legendary status, and the classic s’mores is undoubtedly one of them. The delightful trio of crunchy graham cracker, rich melted chocolate, and gooey toasted marshmallow evokes campfire memories and pure indulgence. While a roaring bonfire isn’t always at hand, you can capture that magical experience right in your kitchen with these incredible S’mores Brownies. Adapted from an old Cook’s Country article known for its innovative brownie variations, this recipe elevates a simple dessert into a truly show-stopping treat that’s perfect for any occasion.

Crafting the Perfect S’mores Brownie: A Symphony of Layers
What makes these 8-inch pan S’mores Brownies truly special is the thoughtful construction of their three distinct layers, each contributing a vital element to the overall experience. This version is meticulously comprised of a sweet, buttery graham cracker crumb crust at the base, providing that signature crisp texture and honeyed flavor. This is then generously topped with a rich, decadent layer of fudgy chocolate brownies, which are designed to be intensely chocolaty and incredibly moist. Finally, a mountain of perfectly broiled marshmallows crowns the entire creation, adding a cloud-like texture and that unmistakable caramelized, slightly smoky s’mores aroma. The contrast of textures and flavors in every bite is simply irresistible, making these brownies a beloved dessert for chocolate and s’mores enthusiasts alike.

Tips for Flawless S’mores Brownies Every Time
Achieving bakery-quality S’mores Brownies, especially when working with rich, fudgy textures, often comes down to a few key techniques. For effortless removal and a pristine presentation, we highly recommend lining your 8-inch square pan with nonstick foil, leaving an overhang on the sides. This thoughtful step creates “handles” that allow you to easily lift the entire slab of brownies from the pan once cooled, preventing any sticking and ensuring your beautiful layers remain intact. You can also use parchment paper for a similar effect, ensuring it covers the bottom and extends up the sides.
But the secret to truly clean cuts? Patience and a bit of freezer magic! After baking and allowing the brownies to cool completely on a wire rack, resist the urge to slice into them warm. Instead, once fully cooled, lift the entire slab of 8-Inch Pan S’mores Brownies from the pan using your foil or parchment overhang. For the cleanest, most precise squares, transfer the whole slab to your freezer for at least 30-60 minutes, or even longer if time allows. Freezing firms up the fudgy brownie and the sticky marshmallows, making them much easier to cut without tearing or smudging. Use a sharp chef’s knife and clean it between cuts for the best results. A hot, dry knife works wonders; simply run it under hot water, wipe it clean, and make your cut.

A Journey of Baking & Sweet Perfection
Over the years, like any passionate baker, I’ve continuously worked on refining my technique and presentation. Baking is as much an art as it is a science, and there’s immense satisfaction in seeing how practice improves the outcome. For a bit of nostalgia and a visual testament to this journey, here’s an older photo of my s’mores brownies. It serves as a sweet reminder of how far a little dedication and a lot of love for baking can take you, culminating in the refined and delicious recipe you see today.

This commitment to improvement ensures that each batch of these 8-inch pan S’mores Brownies is better than the last, delivering that perfect fudgy texture, crisp crust, and golden-brown marshmallow topping that truly makes them stand out. The recipe has been fine-tuned to ensure a consistent, delightful result for home bakers of all skill levels.
Recipe for 8-Inch Pan S’mores Brownies

8 Inch Pan S’mores Brownies
Anna
Pin Recipe
Ingredients
Crust:
- ¾ cup graham cracker crumbs (about 5-6 full sheets of graham crackers, finely crushed)
- 1 tablespoon granulated sugar
- 4 tablespoons unsalted butter, melted
- Pinch of salt optional, enhances flavor
Fudgy Brownie Filling:
- 3 ounces unsweetened chocolate, chopped
- ½ cup unsalted butter (4 ounces)
- 2 large eggs
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- ½ teaspoon baking powder
- ⅔ cup all-purpose flour
- 2 cups mini marshmallows approximately, for topping
Instructions
-
Prepare for Baking: Preheat your oven to 350 degrees F (175 degrees C). For easy removal, line an 8-inch square metal baking pan with nonstick aluminum foil, ensuring the foil extends over the edges to create “handles.”
-
Make the Graham Cracker Crust: In a medium bowl, combine the graham cracker crumbs with the sugar, melted butter, and a pinch of salt (if using). Mix until well combined and the crumbs are moistened. Press this mixture firmly and evenly into the bottom of the prepared 8-inch pan. Bake the crust for 6 minutes, then remove from the oven and set aside.
-
Melt Chocolate and Butter: In a microwave-safe bowl, a double boiler, or a heavy saucepan set over low heat, gently melt the chopped unsweetened chocolate and unsalted butter together. Stir frequently until the mixture is smooth and fully melted. Remove from heat and let it cool slightly for about 5 minutes.
-
Combine Wet Ingredients: In a separate large mixing bowl, whisk together the large eggs, granulated sugar, and vanilla extract until they are light, fluffy, and well combined.
-
Finish the Brownie Batter: Gradually stir the slightly cooled chocolate and butter mixture into the egg mixture until smooth. Next, stir in the salt and baking powder. Finally, add the all-purpose flour and mix just until well blended and no dry streaks remain. Be careful not to overmix the batter.
-
Bake the Brownie Layer: Pour the rich brownie mixture evenly over the pre-baked graham cracker crust in the prepared pan. Return the pan to the oven and bake for 22-26 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs, but not wet batter. The edges should be set.
-
Add Marshmallow Topping: Carefully remove the brownies from the oven. Immediately sprinkle the marshmallows generously and evenly over the warm brownie layer. You want a good, thick layer for that authentic s’mores experience.
-
Broil the Marshmallows: Adjust your oven rack so that the brownies are approximately 6 inches from the broiler element. Set your oven broiler to high. Place the pan under the broiler for about 1 minute, or until the marshmallows are beautifully golden brown and lightly toasted. This step requires constant vigilance – marshmallows can go from perfect to burnt in a matter of seconds!
-
Cool, Chill, and Serve: Remove the pan from the oven and let the brownies cool completely on a wire rack at room temperature. Once cool, for the best texture and easiest slicing, chill the entire slab in the refrigerator for at least 2-3 hours, or even overnight. Once thoroughly chilled, use the foil handles to lift the brownies from the pan and transfer to a cutting board. For super clean cuts, freeze the slab for 30 minutes before slicing into squares with a sharp, warm knife. Enjoy your delicious 8-inch pan S’mores Brownies!
Customizing Your S’mores Brownies: Creative Twists
While this classic 8-inch pan S’mores Brownie recipe is perfect as is, there’s always room for a little creativity to make it your own. Here are some ideas to customize your next batch:
- Chocolate Varieties: Experiment with different types of chocolate in the brownie batter. While unsweetened chocolate provides a deep, intense cocoa flavor, you could try a mix of unsweetened and bittersweet, or even add a handful of chocolate chips (milk, dark, or white) into the batter before baking for extra pockets of melted goodness.
- Flavored Marshmallows: Beyond traditional marshmallows, consider using flavored marshmallows if you can find them. Peppermint marshmallows around the holidays or even fruit-flavored ones could add an interesting twist.
- Nutty Crunch: For those who love a bit of crunch, fold in half a cup of chopped pecans or walnuts into the brownie batter. They add a lovely texture and a slightly savory note that complements the sweet s’mores elements.
- Caramel Drizzle: Once the brownies are cooled, a drizzle of warm salted caramel sauce over the top before serving adds another layer of decadent sweetness and sophistication.
- Espresso Boost: A teaspoon of instant espresso powder added to the brownie batter can deepen the chocolate flavor without making the brownies taste like coffee.
- Spiced Crust: Add a pinch of cinnamon or nutmeg to the graham cracker crust mixture for a subtle, warming spice note.
