Ingredients You’ll Need
The magic of Gooey S’mores Bars with Graham Cracker Crust and Toasted Marshmallows Recipe lies in its simple, classic ingredients that come together to create something truly special. Each ingredient plays a key role in balancing textures and flavors, making this dessert a comforting, crave-worthy treat.
- Graham cracker crumbs: About 2 cups provide that signature crispy and sweet base that holds everything together beautifully.
- Unsalted butter (melted): Half a cup melts into the crumbs, adding rich moisture and helping the crust set perfectly.
- Granulated sugar: A quarter cup to sweeten the crust just right without overpowering the other flavors.
- Semi-sweet chocolate chips: Two cups create the luscious chocolate layer – you can swap for milk chocolate for a sweeter profile.
- Mini marshmallows: Four cups are essential for that gooey, toasted topping that turns every bite into an indulgence.
- Optional toppings (crumbled graham crackers, melted chocolate drizzle): These add extra texture and a little visual flair, perfect for topping your bars if you want to get fancy.
How to Make Gooey S’mores Bars with Graham Cracker Crust and Toasted Marshmallows Recipe
Step 1: Prepare the Baking Dish
Start by lining a 9×13-inch baking dish with parchment paper, leaving some overhang on the sides. This simple prep tip makes removing your finished bars from the dish so much easier and keeps everything neat.
Step 2: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures the crust cooks evenly and the chocolate melts just right under the marshmallows.
Step 3: Make the Graham Cracker Crust
In a large mixing bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Stir until the crumbs are fully coated, and the mixture feels like wet sand. This not only brings flavor but also creates the perfect base that crisps up as it bakes.
Step 4: Press and Bake the Crust
Firmly press the crust mixture into the bottom of your prepared pan in an even layer. Then bake it for 8 to 10 minutes until it’s lightly golden and smells irresistible. Let it cool just a bit to keep the layers distinct.
Step 5: Add the Chocolate Layer
Sprinkle the chocolate chips evenly over the warm crust. Give them a couple of minutes to soften, then spread the melted chocolate into a smooth, even layer with a spatula. This step makes sure each bar is packed with melty, luscious chocolate goodness.
Step 6: Top with Marshmallows and Broil
Scatter the mini marshmallows evenly on top of the chocolate layer. Switch your oven to broil, place the pan on the middle rack, and broil for 1 to 2 minutes while keeping a close eye. You want the marshmallows golden and toasted – that irresistible, slightly caramelized crunch on top of soft fluffiness.
Step 7: Cool and Slice
Once broiled to perfection, let the bars cool completely at room temperature. For easier cutting and cleaner edges, pop them in the fridge for 15 to 20 minutes. Use the parchment paper overhang to lift the whole slab, then slice into squares and get ready to enjoy.

Garnishes
To add a personal touch, try sprinkling some crumbled graham crackers or drizzling melted chocolate across the top of the bars once cooled. These small details enhance both the look and flavor, making your creation look extra tempting for guests or loved ones.
Side Dishes
Pair these gooey bars with a scoop of vanilla ice cream or a dollop of whipped cream to balance their sweetness and add a creamy contrast. A hot cup of coffee, rich cocoa, or even a fresh glass of milk also complements their nostalgic flavor beautifully.
Creative Ways to Present
For a fun twist, serve your Gooey S’mores Bars with Graham Cracker Crust and Toasted Marshmallows Recipe on a rustic wooden board alongside fresh berries, nuts, or small bowls of caramel and chocolate sauce for dipping. Wrapping individual bars in parchment and tying with twine also creates perfect grab-and-go treats for parties or kid’s lunches.
Make Ahead and Storage
Storing Leftovers
Store any leftover bars in an airtight container at room temperature if you plan to eat them within a day or two. For longer freshness, keep them refrigerated where they’ll remain moist and delicious for up to a week.
Freezing
If you want to make these bars in advance or save some for later, freezing works wonderfully. Wrap each bar tightly in plastic wrap and place them in a freezer-safe container or bag for up to 2 months. When ready to enjoy, thaw overnight in the fridge.
Reheating
To bring back that fresh-out-of-the-oven warmth, reheat individual bars in the microwave for about 15 to 20 seconds or until the chocolate softens and the marshmallows regain a little softness. You can also pop them under a broiler for a few seconds to re-toast the marshmallows if you like.
FAQs
Can I use different types of chocolate for the bars?
Absolutely! Semi-sweet chocolate chips work great, but feel free to use milk chocolate for a sweeter taste or dark chocolate if you prefer a richer, less sweet flavor. The mix-and-match possibilities are endless.
What can I substitute for graham cracker crumbs?
If you don’t have graham crackers, crushed digestive biscuits or vanilla wafer cookies make excellent substitutes to create a similar crunchy base.
Are mini marshmallows necessary or can I use regular marshmallows?
Mini marshmallows distribute more evenly and toast best, but if you only have larger ones, chop them into smaller pieces for even coverage and melting.
How do I avoid marshmallows burning under the broiler?
Keep a close eye on the bars while broiling since marshmallows can go from perfectly toasted to burnt very quickly. Broil on a lower rack if possible and check every 30 seconds once they start to brown.
Can these bars be made gluten-free?
Yes! Simply use gluten-free graham cracker crumbs to keep the crust delicious while accommodating gluten sensitivities.
