Step‑by‑Step Instructions for S’mores Brownies with Vanilla Bean Marshmallow
Step 1: Preheat and Prepare the Baking Pan
Preheat your oven to 175°C (350°F) and line a 20 cm square baking pan with parchment paper, letting the paper hang over the edges for easy removal. This step ensures your S’mores Brownies with Vanilla Bean Marshmallow will bake evenly without sticking, giving you a perfect base to work with.
Step 2: Melt Chocolate and Butter
In a double boiler, combine the unsalted butter and dark chocolate, stirring gently until melted and smooth, about 5–7 minutes. Once fully melted, remove from heat and allow the mixture to cool slightly before stirring in the granulated sugar, which will create a rich and fudgy brownie base.
Step 3: Mix in Eggs and Vanilla
Add the large eggs one at a time, whisking well after each addition, followed by the vanilla extract. Continue to mix until everything is fully combined, and the batter appears glossy. This step is crucial as the eggs provide structure and moisture to your scrumptiously decadent S’mores Brownies.
Step 4: Combine Dry Ingredients
Sift the all-purpose flour, unsweetened cocoa powder, and salt into the chocolate mixture, folding gently until just combined. Avoid overmixing to maintain the brownies’ fudgy texture, ensuring a rich, chocolatey flavor that complements the marshmallow topping perfectly.
Step 5: Add Crushed Graham Crackers
Carefully fold in the crushed graham crackers, which will add a delightful crunch to the brownie base. Gently pour the batter into the prepared baking pan, using a spatula to evenly spread and smooth the top, setting the stage for your delicious S’mores Brownies with Vanilla Bean Marshmallow.
Step 6: Bake the Brownies
Place the pan in the preheated oven and bake for 20-25 minutes, or until the edges are firm but the center still appears slightly fudgy. This perfect balance creates a luscious brownie texture that will pair wonderfully with the fluffy marshmallow topping.
Step 7: Cool the Brownies
Once baked, remove the brownies from the oven and allow them to cool completely in the pan. This step is essential to prevent the marshmallow from sinking into the warm brownie base, which keeps the layers distinct and beautiful for your S’mores Brownies.
Step 8: Bloom the Gelatin
While the brownies are cooling, combine the powdered gelatin with cold water in a small bowl and let it bloom for 5 minutes. This will prepare the gelatin to create a beautiful and stable marshmallow that will sit perfectly atop your brownies.
Step 9: Prepare the Syrup Mixture
In a saucepan, combine the granulated sugar, light corn syrup, and water. Heat the mixture over medium heat until it reaches 115°C (soft-ball stage), stirring occasionally to ensure it dissolves completely. This syrup is key for creating the light and airy marshmallow topping.
Step 10: Whip the Egg Whites
In a mixing bowl, whip the egg whites until they form soft peaks. Gradually pour in the hot syrup mixture while continuing to whip on high speed until you achieve stiff peaks. This process creates a fluffy marshmallow that will hold its shape when spread on the brownies.
Step 11: Fold in Vanilla Bean Seeds
Once stiff peaks form, gently fold in the scraped vanilla bean seeds to infuse your marshmallow with rich, aromatic flavor. Spread the fluffy mixture evenly over the cooled brownie base, ensuring every bite of your S’mores Brownies with Vanilla Bean Marshmallow has a generous layer of this delightful topping.
Step 12: Toast the Marshmallow
Finally, use a kitchen torch or the broiler to toast the marshmallow layer until it reaches a beautiful golden brown, about 1–2 minutes. Keep a close eye on it to avoid burning, as this step adds a deliciously caramelized finish reminiscent of toasting marshmallows by a campfire. Allow the marshmallow to set for at least 10 minutes before slicing into squares for serving.

How to Store and Freeze S’mores Brownies
Room Temperature: Store S’mores Brownies with Vanilla Bean Marshmallow in an airtight container at room temperature for up to 3 days to keep them fresh and delicious.
Fridge: If you prefer, you can refrigerate the brownies, but this may change the texture of the marshmallow, making it slightly firmer. Consume within a week for best flavor.
Freezer: To freeze, wrap the brownies tightly in plastic wrap and then in aluminum foil. They can last up to 2 months in the freezer. Thaw at room temperature before enjoying!
Reheating: To reheat, microwave individual pieces for 10-15 seconds, just until warm—this restores a bit of the original gooeyness and makes the marshmallow softer.

S’mores Brownies with Vanilla Bean Marshmallow Recipe FAQs
How do I choose the right chocolate?
Absolutely! Opt for high-quality dark chocolate with a cocoa content of at least 60% for a rich flavor. If you prefer a sweeter brownie, feel free to use milk chocolate instead—just remember that this change will slightly alter the final taste.
What’s the best way to store S’mores Brownies?
Store your S’mores Brownies with Vanilla Bean Marshmallow in an airtight container at room temperature, where they’ll stay fresh for up to 3 days. Avoid refrigerating them, as this can firm up the marshmallow topping and change its delightful texture.
Can I freeze S’mores Brownies?
Of course! To freeze, wrap each brownie tightly in plastic wrap, then in aluminum foil to keep out air. They can last up to 2 months in the freezer. When you’re ready to enjoy them, simply thaw at room temperature. For an extra treat, microwave each piece for 10-15 seconds to regain that gooey goodness!
What if my marshmallow topping is too runny?
If your marshmallow topping turns out too runny, it may be due to insufficient whipping or gelatin blooming. Ensure that you whip the egg whites until stiff peaks form before gradually adding the hot syrup. For a more firmer texture, consider adding an extra teaspoon of gelatin dissolved in water next time.
Are there any dietary considerations for this recipe?
Certainly! To make these brownies more accessible, you can substitute the butter with margarine for a dairy-free option, and use gluten-free flour to accommodate those with gluten sensitivity. Always check labels for any allergies, especially with the chocolate and marshmallow ingredients, to ensure they are safe for all your guests—your furry friends and family alike!
