Ingredients:
- 5 whole graham cracker sheets
- ½ cup unsalted butter (113g)
- ½ cup semi-sweet chocolate chips (85g)
- 1 cup sugar (200g)
- 2 large eggs, at room temperature
- ½ cup unsweetened or Dutch processed cocoa powder (40g)
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- ½ cup all-purpose flour (60g)
- 1 – 1½ cups mini marshmallows (45-68g)
- 1 Hershey’s chocolate bar (1.55 oz)
- 1 graham cracker, roughly crushed
For the Graham Cracker Crust
Ingredients:
- 5 whole graham cracker sheets
- ½ cup unsalted butter (113g), melted
Instructions:
- To begin, let’s prepare our graham cracker crust. This forms the delicious base for our S’mores Brownies. Take your 5 whole graham cracker sheets and place them into a food processor. Pulse them until they are finely crushed, resembling coarse crumbs. If you don’t have a food processor, you can place the graham crackers in a resealable plastic bag and crush them with a rolling pin until you achieve the desired consistency.
- In a medium bowl, combine the graham cracker crumbs with the ½ cup of melted unsalted butter. Stir until all the crumbs are evenly moistened. The mixture should look like wet sand.
- Press this graham cracker mixture firmly and evenly into the bottom of an 8×8 inch baking pan. Ensure you create a solid, compact layer to prevent it from crumbling when you cut the brownies later. You can use the bottom of a measuring cup or your hands to press it down. Place the prepared pan into the refrigerator while you move on to the brownie batter. This allows the crust to set up.
For the Decadent Brownie Batter
Ingredients:
- ½ cup unsalted butter (113g), cut into pieces
- ½ cup semi-sweet chocolate chips (85g)
- 1 cup sugar (200g)
- 2 large eggs, at room temperature
- ½ cup unsweetened or Dutch processed cocoa powder (40g)
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- ½ cup all-purpose flour (60g)
Instructions:
- Now, let’s make the fudgy brownie batter that will envelop our s’mores goodness. In a medium, microwave-safe bowl, combine the ½ cup of unsalted butter, cut into pieces, and the ½ cup of semi-sweet chocolate chips. Microwave these in 30-second intervals, stirring between each interval, until the butter is completely melted and the chocolate chips are smooth and glossy. Be careful not to overheat the chocolate. Stir until you have a perfectly smooth and melted chocolate mixture.
- To this melted chocolate and butter mixture, add the 1 cup of sugar. Whisk thoroughly until well combined. The mixture will become slightly lighter in color and may thicken a bit.
- One at a time, add the 2 large eggs, whisking vigorously after each addition until each egg is fully incorporated into the chocolate-sugar mixture. It’s crucial to ensure the eggs are fully mixed to prevent them from cooking when the batter gets warm. Next, stir in the 1 teaspoon of vanilla extract.
- In a separate small bowl, whisk together the ½ cup of unsweetened or Dutch processed cocoa powder, ¼ teaspoon of salt, and ½ cup of all-purpose flour. Sifting the cocoa powder and flour can help prevent lumps and ensure a smoother batter.
- Gradually add the dry ingredients to the wet ingredients, folding them in gently with a spatula until just combined. Be careful not to overmix the batter. Overmixing can develop the gluten in the flour, resulting in tougher brownies. We want a rich, fudgy texture, so stop mixing as soon as you no longer see streaks of dry ingredients.
Assembling and Baking Your S’mores Brownies
Ingredients:
- 1 – 1½ cups mini marshmallows (45-68g)
- 1 Hershey’s chocolate bar (1.55 oz)
- 1 graham cracker, roughly crushed
Instructions:
- Retrieve the chilled graham cracker crust from the refrigerator. Pour the prepared brownie batter evenly over the crust, spreading it out with your spatula to cover the entire surface.
- Now for the s’mores magic! Sprinkle the 1 to 1½ cups of mini marshmallows evenly over the top of the brownie batter. Make sure they are distributed so you get that gooey marshmallow in every bite.
- Next, break the 1 Hershey’s chocolate bar into small pieces and scatter them amongst the marshmallows. This adds an extra layer of classic Hershey’s chocolate flavor that melts beautifully.
- Finally, sprinkle the 1 roughly crushed graham cracker over the top of the marshmallows and chocolate pieces. This gives you that delightful toasted graham cracker crunch that completes the s’mores experience.
- Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until a toothpick inserted into the center of the brownies comes out with moist crumbs attached (not wet batter). The marshmallows should be puffed and golden brown. Keep a close eye on them as the marshmallows can burn quickly. Once baked, remove the pan from the oven and let the S’mores Brownies cool completely in the pan on a wire rack before cutting. This cooling period is essential for the brownies to set properly, ensuring clean slices.

Ultimately, the joy of making these S’mores Brownies lies in the process and the delicious reward. So gather your ingredients, embrace the fun, and get ready to impress yourself and everyone lucky enough to snag a piece. Happy baking!
Frequently Asked Questions about S’mores Brownies:
Q1: How do I ensure my S’mores Brownies are fudgy and not cakey?
To achieve a fudgy texture, it’s crucial to avoid overmixing the batter once the flour is added. Mix just until combined. Also, using melted butter and a higher ratio of chocolate to flour in the brownie base contributes significantly to fudginess.
Q2: Can I make these S’mores Brownies ahead of time?
Yes, you can! The brownie base can be baked and cooled completely a day in advance. You can then add the marshmallow and graham cracker topping just before serving or a few hours prior. If adding the topping ahead, you might need to briefly warm them in the oven to re-melt the marshmallows slightly.
