Ingredients You’ll Need
The magic of S’mores Bars is in their simplicity. Every classic flavor is represented, and each ingredient plays a starring role—from the crunchy, honeyed graham cracker base to the creamy chocolate and marshmallows that get perfectly gooey in the oven. Here’s what you’ll need, with a few tips to make each component shine.
- Graham crackers: Crushed into crumbs, they form the sweet and crunchy foundation of your S’mores Bars; use your food processor for an extra-fine texture.
- Unsalted butter: Melted butter binds the graham cracker layer together and adds rich, toasty flavor—go for unsalted so you can control the salt level yourself.
- Salt: Just a pinch brings out the sweetness and highlights all the chocolatey, marshmallowy goodness.
- Mini marshmallows: The star of the show for that gooey, stretchy texture and classic s’mores flavor; their size helps them melt and toast evenly.
- Milk chocolate chips: Choose a good quality brand for that creamy, melt-in-your-mouth layer that channels classic campfire s’mores.
How to Make S’mores Bars
Step 1: Prep and Crush
Start by preheating your oven to 350 degrees F. Crush your graham crackers to fine, sandy crumbs—either with a food processor or by sealing them in a bag and giving them a good whack with a rolling pin. Crushing them well helps the bars hold together better once baked.
Step 2: Make the Graham Cracker Base
Mix the graham cracker crumbs (be sure to set aside about 1/4 cup for later!), melted butter, and salt in a medium bowl until the mixture resembles wet sand. Press this mixture firmly and evenly into a 9×13-inch baking pan. Baking it for 10 minutes helps the crust set up with a nicely toasted, golden flavor.
Step 3: First Marshmallow Layer
Next, sprinkle 4 cups of mini marshmallows evenly over the hot graham crust. Return the pan to the oven and bake for 10 more minutes. The marshmallows will puff and turn lightly golden, setting the stage for gooey perfection.
Step 4: Add Milk Chocolate
Let the pan cool for about five minutes—just long enough for the marshmallows to deflate a bit but not set completely. Now, shower the entire surface with all those milk chocolate chips, creating a luscious, melty layer. Keep the chips as evenly spread out as you can so every bite is chocolatey.
Step 5: The Final Marshmallow & Crumble Touch
Scatter the remaining marshmallows and the reserved graham cracker crumbs on top. Slide the pan back into the oven for a final 10 minutes. Watch as the marshmallows toast to golden brown and the chocolate melts into waves—it’s like a campfire came right to your kitchen.
Step 6: Cool and Slice
Patience is a virtue here! Let the S’mores Bars cool completely in the pan before slicing. This cooling step helps everything firm up so you get clean, distinct layers in every bar—plus, it makes cutting them less sticky and more satisfying.
How to Serve S’mores Bars

Garnishes
A light dusting of extra crushed graham crackers or even a drizzle of melted milk chocolate can make your S’mores Bars look absolutely bakery-worthy. If you love that classic campfire look, use a kitchen torch to toast the top layer of marshmallows a little more for extra flair and flavor.
Side Dishes
These sweet, nostalgic bars are lovely next to something simple and refreshing. Try serving them with fresh berries for a burst of tartness, a scoop of vanilla ice cream, or a cold glass of milk. They’re also fabulous as part of a larger dessert spread with brownies or fresh fruit.
Creative Ways to Present
For parties or gifts, slice your S’mores Bars into bite-size pieces and pile them into a mason jar or wrap in parchment with a twine bow. Stack the bars and skewer them on sticks for a whimsical “campfire” treat. Or, make a dessert board with S’mores Bars at the centerpiece—add cookies, fruit, and fun marshmallow varieties for a show-stopping spread.
Make Ahead and Storage
Storing Leftovers
Keep your leftover S’mores Bars fresh by storing them in an airtight container at room temperature for up to three days. If your kitchen is warm, you can store them in the fridge instead; just bring them to room temp before serving for the best texture.
Freezing
S’mores Bars freeze beautifully! Once completely cooled and cut, wrap each bar individually in plastic wrap and freeze in a zip-top bag for up to three months. Thaw them on the counter for an easy, anytime treat—just as rich and gooey as the day you made them.
Reheating
If you want a freshly-baked feel, pop your S’mores Bars in the microwave for 10-15 seconds to warm and soften the chocolate and marshmallow. For a slightly toasted top, use your oven’s broiler for a minute—but keep a close eye so nothing burns!
FAQs
Can I use large marshmallows instead of mini?
Mini marshmallows melt and toast more evenly, but you can use large marshmallows if you cut them up into smaller pieces. Just try to distribute them evenly across the bars so you get that gooey topping in every bite.
What’s the best way to crush graham crackers?
A food processor makes quick work of graham crackers, but a sturdy zip-top bag and rolling pin will do the trick if you don’t have one. Crush them until they’re mostly fine crumbs for the best crust.
Can I substitute the milk chocolate?
Absolutely! If you love a richer flavor, swap in semisweet chocolate chips, or try dark chocolate for a more grown-up twist. Even peanut butter chips work well if you want something totally different.
Do I have to let the bars cool before cutting?
It’s tempting to dive right in, but waiting for the S’mores Bars to fully cool is key for clean slices. Otherwise, you’ll end up with a gooey (though still delicious) mess—patience pays off!
Can I double the recipe?
Yes, just use a larger baking pan or two 9×13 pans. Keep an eye on the baking times, as the bars may need a few extra minutes if you’re making a bigger batch. Perfect for feeding a crowd!
Final Thoughts
Whether you’re hosting a crowd or just looking for the ultimate sweet treat, these S’mores Bars are guaranteed to thrill everyone who tries them. Don’t wait for summer or a campfire—dive into this recipe and bring those nostalgic flavors to your kitchen any time you like. Happy baking!
