- Crushed Graham Crackers (80 g) – Adds texture and flavor; substitute with gluten-free graham crackers.

With these S’mores Brownies with Vanilla Bean Marshmallow ingredients at hand, you’re all set to indulge in this delightful treat!
Step‑by‑Step Instructions for S’mores Brownies with Vanilla Bean Marshmallow
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 175°C (350°F). While the oven warms up, take a 20 cm square baking pan and line it with parchment paper, letting the edges overhang for easy removal later. This will ensure that your S’mores Brownies are easy to lift from the pan once baked, making for a tidy and simple serving process.
Step 2: Melt Butter and Chocolate
In a heatproof bowl set over a simmering water bath, combine the unsalted butter and chopped dark chocolate. Stir continuously until melted and smooth, about 5-7 minutes. Once combined, remove the bowl from the heat and allow it to cool slightly, ensuring it’s not hot when you mix in the next ingredients for your fudgy brownie base.
Step 3: Mix Sugar and Eggs
Add the granulated sugar to the melted chocolate mixture and stir until well combined. Then, crack in the eggs one at a time, mixing vigorously after each addition until the mixture is glossy and fully incorporated. Finally, add the vanilla extract, enhancing the flavor profile of your S’mores Brownies with Vanilla Bean Marshmallow, and mix until smooth.
Step 4: Add Dry Ingredients
Sift the all-purpose flour, unsweetened cocoa powder, and salt directly into the wet ingredients. Using a spatula, gently fold the dry ingredients into the mixture until just combined; be careful not to overmix to maintain a tender texture. This rich batter will create a fudgy base for your brownies that’s simply irresistible.
Step 5: Incorporate Graham Crackers
Now it’s time to add the crushed graham crackers into the brownie batter. Fold them in gently, ensuring they are evenly distributed throughout. Once combined, pour the batter into your prepared baking pan, using a spatula to smooth the top. This step is crucial for achieving that perfect brownie shape and texture.
Step 6: Bake the Brownies
Place the pan in your preheated oven and bake for 20–25 minutes. The edges should set firmly while the center remains slightly fudgy—ideal for that gooey texture. To check for doneness, insert a toothpick; it should come out with a few moist crumbs. Once baked, let the brownies cool completely in the pan on a wire rack.
Step 7: Bloom the Gelatin
While your brownies cool, prepare the vanilla bean marshmallow topping. In a small bowl, combine cold water with the powdered gelatin and let it bloom for about 5 minutes. This vital step ensures that your marshmallow will achieve its fluffy texture when whipped—don’t skip it!
Step 8: Heat the Sugar Mixture
In a saucepan, mix together the granulated sugar, light corn syrup, and water. Heat the mixture over medium flame until it reaches 115°C (soft-ball stage). Stir occasionally to help dissolve the sugar, creating a syrup that will sweeten and stabilize your marshmallow layer when combined.
Step 9: Whip the Egg Whites
Using a stand mixer or electric mixer, whip your egg whites until soft peaks form. With the mixer running on medium speed, slowly drizzle in the hot syrup from your saucepan. Continue to whip until stiff peaks form and the bowl feels cool to the touch. This step creates an airy texture for your marshmallow, making your S’mores Brownies even more delightful.
Step 10: Combine Vanilla and Spread
Once your marshmallow has reached the right texture, fold in the vanilla bean seeds, adding a beautiful speckled effect and rich flavor. Carefully spread the fluffy marshmallow topping over the cooled brownie base, smoothing it out to cover every corner. This will create a dreamy, sweet layer on top of your brownies.
Step 11: Toast the Marshmallow
To finish, use a kitchen torch or place the pan under a broiler for a few minutes to toast the marshmallow layer until it turns golden brown. Keep a close eye during this process to avoid burning. This will add a lovely toasted flavor reminiscent of classic campfire s’mores, enhancing your dessert experience.
Step 12: Set and Slice
Let the toasted marshmallow set for about 10 minutes after removing from heat. This slight cooling allows the layers to adhere better. Once set, use the overhanging parchment to lift the brownies out of the pan and slice into squares. Your S’mores Brownies with Vanilla Bean Marshmallow are now ready to be enjoyed!

How to Store and Freeze S’mores Brownies
Room Temperature: Store your S’mores Brownies in an airtight container at room temperature for up to 3 days. This will keep the brownie base moist while maintaining the marshmallow’s texture.
Fridge: Avoid refrigeration, as this can make the marshmallow layer sticky and less enjoyable. It’s best to keep them in a cool, dry place for optimal flavor and texture.
Freezer: If you’d like to save some for later, slice the brownies (without the marshmallow) and wrap them tightly in plastic wrap. Place them in an airtight container or freezer bag, and they can be frozen for up to a month—perfect for future cravings!
Reheating: When ready to enjoy your brownies, let them thaw at room temperature, and if desired, reheat briefly in the microwave for a warm, gooey treat.
