How to Make S’mores Brownies
-
Prep Crust: Preheat your oven to 350°F (175°C) and spray a baking dish with cooking spray. Crush the graham crackers into fine crumbs and press them into the bottom of the dish to create a sturdy crust, ensuring it’s even and compact.
-
Mix Brownie Batter: In a mixing bowl, prepare the brownie mix according to package instructions, adding the necessary eggs, oil, and water. Pour this delicious batter over the graham cracker crust, spreading it out evenly to cover.
-
Add Chocolate: Chop up the Hershey bars into chunks and sprinkle them generously over the brownie batter. The rich chocolate will meld beautifully into the brownies as they bake.
-
Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes. Keep an eye on them until the edges are set but the middle remains slightly soft—this contributes to that delicious fudgy texture!
-
Top with Marshmallows: Once baked, remove the brownies from the oven and evenly distribute mini marshmallows on top. Return the dish to the oven and broil for just a few minutes, watching closely until the marshmallows turn golden brown and puff up.
-
Cool & Serve: Allow the brownies to cool slightly before cutting them into squares. For a clean cut, use a knife that you’ve sprayed with cooking spray to prevent sticking.
Optional: Serve warm with a scoop of vanilla ice cream for an extra indulgent treat!

S’mores Brownies Recipe FAQs
How do I select the best graham crackers for these brownies?
Choose graham crackers that are fresh and unbroken for optimal crunch in your crust. Look for packages without any visible dark spots or signs of staleness. If you’re feeling adventurous, consider using flavored graham crackers, like cinnamon, to add a unique twist to your brownies!
How should I store leftover S’mores Brownies?
Store your S’mores Brownies in an airtight container at room temperature for up to 3 days to keep them soft and fudgy. If you want them to last longer, refrigerate them for up to a week. Just make sure to seal them well to prevent them from drying out.
Can I freeze S’mores Brownies?
Absolutely! To freeze, allow the brownies to cool completely, then wrap them tightly in plastic wrap and place them in a freezer-safe container. They can be frozen for up to 3 months. When you’re ready to enjoy them, simply thaw them overnight in the fridge or microwave for 15-20 seconds until warm and gooey.
What should I do if my brownies turn out too dry?
If your brownies are dry, they may have been overbaked or cooked at too high of a temperature. Make sure to set a timer and check for doneness around the 25-minute mark. The key is to remove them when the edges are set, but the center is still slightly soft. If you find them dry after baking, consider serving them warm with ice cream or a drizzle of chocolate sauce to enhance moisture!
Are these S’mores Brownies safe for those with nut allergies?
Yes, the base recipe is generally nut-free; however, always check your brownie mix and chocolate bar labels to ensure they’re produced in nut-free facilities if allergies are a concern. If desired, you can easily make these brownies nut-free by skipping any additional nut mix-ins!
What can I substitute if I don’t have marshmallows?
In a pinch, you can use whipped cream or chocolate ganache as a topping alternative. For unique variations, consider using coconut whipped cream for a tropical flair or a layer of chocolate chips that will melt slightly—just ensure they melt enough to mimic that ooey-gooey s’mores texture.
