Ingredients

- 2 cups mini marshmallows
- 1 cup chocolate chips
Step-by-Step
- Prepare the Graham Cracker Crust

Bake the brownies in the preheated oven for 20 to 25 minutes, or until the edges look set but the center is still slightly fudgy. - Add Toppings
Remove the pan from the oven and immediately sprinkle the mini marshmallows and chocolate chips evenly over the top. - Finish Under the Broiler
Return the pan to the oven and broil on high for 1 to 2 minutes, watching closely, until the marshmallows are golden and toasted. Be careful—they brown quickly! - Cool and Slice
Allow the brownies to cool completely before cutting into squares. Enjoy the gooey, melty deliciousness!
What to Serve S’Mores Brownies With
S’Mores Brownies are a crowd-pleasing dessert on their own, but why not elevate your experience? For a cozy treat, serve them with a mug of hot chocolate or a cold glass of milk. If you’re hosting a gathering, pair them with fresh berries or vanilla ice cream for a truly decadent combo. Want to spread dessert joy? Bring a platter to your next picnic, BBQ, or potluck—they make an excellent finger food alongside savory snacks like popcorn or salted nuts.
Top Tips for Perfecting
- For the perfect crust, press the graham cracker crumb mixture firmly so it holds together and adds just the right crunch.
- If you’re feeling adventurous, swap in dark chocolate or peanut butter chips for an extra flavor twist.
- To avoid over-browning the marshmallows, always watch them under the broiler—one minute is often enough!
- For easier slicing, use a plastic knife or coat your regular knife with cooking spray for clean edges.
- Store fully cooled brownies in an airtight container so the marshmallows stay soft and gooey.
- No graham cracker crumbs? Crushed digestive biscuits or vanilla wafer cookies are good substitutes.
Storing and Reheating Tips
Leftover S’Mores Brownies can be stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, wrap pieces individually and freeze for up to 3 months—just thaw at room temperature before serving. To reheat, pop a brownie in the microwave for 10 to 15 seconds to revive that gooey, just-baked marshmallow topping, or enjoy chilled for a more fudge-like texture.
FAQs
Can I make these brownies from scratch instead of using a box mix?
Absolutely! Feel free to use your favorite homemade brownie recipe instead of a boxed mix.
How do I prevent the marshmallows from burning?
Keep a close eye on them under the broiler—just 1 to 2 minutes is usually plenty. Pull them out as soon as they’re golden and toasty.
Can I use regular-size marshmallows?
Mini marshmallows melt and toast evenly, but you can cut regular marshmallows into smaller pieces as a substitute.
Are S’Mores Brownies gluten-free?
They can be! Just use a gluten-free brownie mix and gluten-free graham crackers.
Can I add nuts or caramel?
Of course! Chopped nuts, caramel drizzle, or even peanut butter cups make tasty additions.
