There's something incredibly nostalgic about the taste of s'mores, isn't there? For me, the aroma of a crackling campfire, the warmth against my face, and the anticipation of a perfectly toasted marshmallow sandwiched between graham crackers and melting chocolate brings back a flood of cherished childhood memories. Summer evenings spent with family and friends, sticky fingers, and laughter under a star-filled sky – those are the moments that truly define joy. But what if you could capture that very essence, that gooey, chocolatey, crunchy perfection, and bring it right into your kitchen, any time of year? That's precisely what inspired me to create these incredible Fudgy S'mores Brownies. They are a decadent homage to those beloved campfire treats, transformed into a rich, chewy brownie that's impossible to resist. This recipe isn't just about baking; it's about rekindling those warm, fuzzy memories, one glorious, chocolate-packed bite at a time.
My journey to perfecting the Fudgy S'mores Brownies began on a rainy Saturday when my kids were begging for s'mores, but a backyard bonfire was out of the question. I remembered a vague idea I’d seen online about s’mores bars, and the challenge was on. I wanted a brownie that was truly fudgy, not cakey, with distinct layers that celebrated each component of a classic s’more. It took a few attempts – some were too dry, some had marshmallows that just vanished into the brownie – but persistence (and a lot of delicious experimentation) paid off. The result is a brownie that delivers on every front: a rich, dense chocolate base, a satisfying crunch from the graham crackers, and a beautifully gooey, slightly caramelized marshmallow topping that will make you close your eyes in pure bliss. These Fudgy S'mores Brownies have since become a family legend, requested for every potluck, birthday, and "just because" occasion. They are truly the ultimate comfort dessert, embodying all the fun and flavor of the outdoors, right in your home kitchen.

Key Ingredient Notes
Crafting the perfect Fudgy S'mores Brownies requires attention to a few key ingredients that truly make a difference in the final product:
High-Quality Cocoa Powder
The foundation of our Fudgy S'mores Brownies is, of course, chocolate, and a significant part of that comes from cocoa powder. I highly recommend using a good quality unsweetened Dutch-processed cocoa powder. Dutch-processed cocoa has been treated to reduce its acidity, resulting in a darker color and a smoother, less bitter chocolate flavor. This contributes to the deep, rich chocolatey taste and signature fudgy texture we're aiming for. While natural cocoa powder can work, Dutch-processed will give you that superior, intense chocolate profile that truly shines in these Fudgy S'mores Brownies. Don't skimp here; it's worth the small investment for big flavor.
Fresh Marshmallows
For that iconic gooey topping, fresh marshmallows are non-negotiable. Stale marshmallows can dry out or become hard when baked, losing that irresistible stretch and chewiness that defines a good s'more. While standard large marshmallows work wonderfully, you can also use mini marshmallows for a more even spread, though they tend to brown faster. If you're feeling adventurous, try using artisanal vanilla marshmallows for an extra layer of flavor. Ensure they are placed evenly on top of the Fudgy S'mores Brownies for a consistent, golden brown finish. The magic truly happens when these turn perfectly golden brown and slightly caramelized on top.
Good Quality Butter
Butter isn't just a fat here; it's a flavor enhancer and contributes significantly to the brownie's texture. Using a high-quality unsalted butter will provide a cleaner, richer flavor profile without introducing extra salt that can throw off the balance of the recipe. Make sure your butter is at room temperature if specified in the recipe, or melted as directed, to ensure proper incorporation with the other ingredients. The richness of the butter is essential for achieving that luxurious, fudgy mouthfeel that makes these Fudgy S'mores Brownies so utterly addictive. If you are looking for excellent ways to store your butter or other ingredients, I highly recommend investing in some Basics Glass Food Storage containers. They are fantastic for keeping everything fresh and organized!

Step-by-Step Guide with Pro Tips
Let's dive into making these incredible Fudgy S'mores Brownies!
- Step 1: Preheat your oven to 350°F (175°C) and line a 9x13 inch baking pan with parchment paper, leaving an overhang on the sides to easily lift the brownies out later. Lightly grease the parchment paper.
- Step 2: Create the graham cracker crust. In a medium bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Press this mixture evenly into the bottom of the prepared pan. Bake for 8-10 minutes, or until lightly golden. Remove from oven and set aside to cool slightly while you prepare the brownie batter.
- Step 3: Prepare the fudgy brownie base. In a large, heatproof bowl, combine the melted butter and granulated sugar. Whisk vigorously for about 1-2 minutes until smooth and slightly thickened. This helps create that crinkly top!
- Step 4: Add the eggs one at a time, beating well after each addition until fully incorporated and the mixture is glossy. Stir in the vanilla extract.
- Step 5: Sift together the cocoa powder, all-purpose flour, baking powder, and salt in a separate bowl. Gradually add the dry ingredients to the wet ingredients, mixing only until just combined. Be careful not to overmix; overmixing can lead to tougher brownies.
- Step 6: Fold in the chocolate chips or chunks. Pour the brownie batter evenly over the slightly cooled graham cracker crust in the prepared pan.
- Step 7: Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached (not wet batter). You want them slightly underbaked for ultimate fudginess.
- Step 8: Remove the pan from the oven. Evenly sprinkle the marshmallows over the hot brownies. If using large marshmallows, you might want to cut them in half for better coverage.
- Step 9: Return the Fudgy S'mores Brownies to the oven and bake for another 3-5 minutes, or until the marshmallows are puffed and beautifully golden brown. Keep a close eye on them, as marshmallows can burn quickly!
- Step 10: Once the marshmallows are toasted, remove the pan from the oven and immediately sprinkle with additional chocolate chips (if desired). The residual heat will melt them slightly. Let the brownies cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang.
- Step 11: Once completely cooled (this is crucial for clean cuts!), slice into squares. A hot knife dipped in water and wiped clean between cuts will give you the cleanest edges for your Fudgy S'mores Brownies. Enjoy!
Variations & Serving Suggestions
These Fudgy S'mores Brownies are fantastic as is, but there's always room for a little creative flair! Here are some ideas to make them even more special:
Creative Variations
- Peanut Butter S'mores Brownies: Swirl a few tablespoons of creamy peanut butter into the brownie batter before baking. You can also drizzle melted peanut butter over the toasted marshmallows for an extra nutty kick. This adds a delightful dimension to the Fudgy S'mores Brownies.
- Spiced S'mores Brownies: Add a pinch of cinnamon or a dash of chili powder to your brownie batter for a subtle warmth and complexity that complements the chocolate beautifully.
- Coffee-Infused Brownies: Dissolve 1-2 teaspoons of instant espresso powder in the melted butter or hot water component of your brownie batter. Coffee enhances chocolate flavor without making the brownies taste like coffee.
- Different Chocolates: Experiment with different types of chocolate chips in your Fudgy S'mores Brownies – white chocolate, milk chocolate, or even a mix of dark and milk for varying levels of sweetness.
- Nutty Crunch: Fold in chopped pecans or walnuts into the brownie batter for an added layer of crunch and flavor. This contrasts wonderfully with the gooey marshmallows.
Serving Suggestions
- Warm with Ice Cream: Serve a square of Fudgy S'mores Brownies warm with a scoop of vanilla bean ice cream. The contrast of warm brownie and cold ice cream is heavenly.
- Drizzle with Caramel or Hot Fudge: For an extra indulgent treat, drizzle your Fudgy S'mores Brownies with a generous amount of caramel sauce or hot fudge before serving. You might also enjoy our Decadent Chocolate Fudge Layer Cake with Caramel Drizzle for another caramel-chocolate fix!
- With Fresh Berries: A side of fresh raspberries or strawberries can cut through the richness of the brownies and add a lovely tart balance.
- Milk Pairing: Nothing beats a classic glass of cold milk with a rich chocolate brownie. It's simple, perfect, and enhances the Fudgy S'mores Brownies experience.
- Party Platter: Cut into smaller bites and arrange on a platter for parties. They make a stunning addition to any dessert spread, perhaps alongside some Divine White Chocolate Raspberry Cookies.

FAQs
Can I make Fudgy S'mores Brownies ahead of time?
Yes, Fudgy S'mores Brownies can be made 1-2 days in advance. Store them in an airtight container at room temperature. For optimal gooeyness, you can gently reheat individual servings in the microwave for a few seconds before serving.
How should I store leftover Fudgy S'mores Brownies?
Store leftover Fudgy S'mores Brownies in an airtight container at room temperature for up to 3-4 days. While not necessary, they can also be refrigerated for a slightly firmer texture, but bring them back to room temperature or warm slightly before eating for the best experience.
What kind of marshmallows are best for S'mores Brownies?
Large marshmallows work wonderfully as they create a thick, gooey layer when toasted. You can also use mini marshmallows for more even coverage, but they will toast faster, so keep a close eye on them. Ensure your marshmallows are fresh for the best gooey texture.
Why are my Fudgy S'mores Brownies not fudgy?
Brownies that aren't fudgy are often overbaked. For ultimate fudginess, remove them from the oven when a toothpick inserted into the center comes out with moist crumbs attached, not wet batter, but also not completely clean. The brownies will continue to set as they cool.
