Step‑by‑Step Instructions for S’mores Brownies
Step 1: Preheat and Prepare
Preheat your oven to 325°F (160°C) and line an 8×8-inch baking pan with foil or parchment paper for easy removal. Grease the lining lightly with cooking spray or butter to ensure the S’mores Brownies come out effortlessly when baked.
Step 2: Make the Crust
In a mixing bowl, combine melted unsalted butter with graham cracker crumbs, stirring until fully integrated. Press this mixture firmly into the bottom of the prepared pan, creating an even layer for your crust. This buttery base will provide a delicious foundation for your fudgy brownies.
Step 3: Prepare the Brownie Batter
In a microwave-safe bowl, melt together the remaining unsalted butter, granulated sugar, unsweetened cocoa powder, and salt, heating in 30-second increments until smooth. Stir these ingredients until glossy and combined, ensuring no lumps remain; this mixture will form the rich chocolate base of your S’mores Brownies.
Step 4: Add Eggs and Flour
Once the mixture has cooled slightly, mix in the vanilla extract and large eggs, whisking until the batter is thick and shiny. Gently fold in the all-purpose flour and milk chocolate chips, taking care not to overmix. This step creates that deliciously fudgy texture in your S’mores Brownies.
Step 5: Layer the Batter and Marshmallow
Pour half of the brownie batter over the prepared crust, spreading it evenly. Add dollops of half the marshmallow fluff over the batter, then spoon the remaining brownie batter on top. Finish by dolloping with the rest of the marshmallow fluff, giving it a light swirl to create beautiful, gooey layers.
Step 6: Bake the Brownies
Place your pan in the preheated oven and bake for 25 minutes. The S’mores Brownies should look slightly moist when a toothpick is inserted; this indicates they are perfectly fudgy. Increase the oven temperature to 375°F (190°C), top with mini marshmallows, and bake for an additional 3-5 minutes until they’re puffed and golden.
Step 7: Cool and Slice
Remove the brownies from the oven and allow them to cool completely in the pan before slicing. For clean cuts, use a sharp knife dipped in warm water. These S’mores Brownies are best enjoyed after cooling down, revealing their decadent, gooey goodness in each square!

Make Ahead Options
These indulgent S’mores Brownies are a fantastic choice for busy home cooks looking to save time! You can prepare the graham cracker crust and brownie batter up to 24 hours in advance. Simply press the crumb mixture into the pan and refrigerate it, and store the brownie batter in an airtight container. The marshmallow fluff can also be measured out and set aside (keep it covered to prevent drying). When you’re ready to bake, pour the brownie batter over the crust, dollop with marshmallow fluff, and swirl lightly before baking. This way, you’ll enjoy deeply satisfying, gooey treats with minimal last-minute effort, just as delicious as fresh!

Expert Tips for S’mores Brownies
Swirl Wisely: Avoid over-swirl when mixing in the marshmallow fluff; gentle strokes maintain distinct layers and keep the gooey texture intact.
Watch the Toasting: Keep a close eye on the mini marshmallows as they bake. They can go from golden to burnt quickly, so monitor them closely at 375°F.
Cool Completely: Let the brownies cool fully before cutting. This ensures clean slices and a beautifully presented treat. A sharp, warm knife works best!
Gluten-Free Friendly: For gluten-free S’mores Brownies, opt for a gluten-free graham cracker and a 1:1 gluten-free flour blend to maintain delicious flavor and texture.
Stay Fudgy: Be careful not to overbake. The toothpick should come out with a few moist crumbs; this guarantees that rich, fudgy finish everyone loves.
How to Store and Freeze S’mores Brownies
Room Temperature: Store S’mores Brownies in an airtight container at room temperature for up to 3 days. This keeps them soft and chewy, perfect for an on-the-go treat.
