Ingredients You’ll Need
Making S’more Bars is wonderfully simple, and it all starts with just a handful of pantry staples. Each ingredient plays an important role—from the graham cracker crumbs creating that crisp, flavorful base, to the rich butter binding everything together, and the chocolate and marshmallows building that classic s’mores texture and sweetness.
- 2 cups graham cracker crumbs: This forms the crunchy and slightly sweet crust that supports the bars.
- 1/2 cup melted butter: Helps bind the graham cracker crumbs together and adds richness.
- 4 cups chocolate chips: The star ingredient for that decadent chocolate layer—use semi-sweet for balance or milk chocolate for a sweeter bite.
- 1 package mini marshmallows: These gooey pockets of sweetness melt and brown beautifully on top.
How to Make S’more Bars
Step 1: Get Your Oven and Pan Ready
Start by preheating your oven to 350 degrees Fahrenheit. Grease a 9×13-inch baking pan generously with cooking spray to ensure your bars don’t stick and come out perfectly intact after baking.
Step 2: Prepare the Graham Cracker Crust
In a bowl, combine your graham cracker crumbs with the melted butter. This mixture should resemble wet sand and hold together when pressed. Press the mixture firmly into the bottom and up the sides of your baking dish—this forms the hearty base of your S’more Bars.
Step 3: Bake the Crust
Bake the pressed crust for 8 minutes until it is just set and starting to turn golden. This step ensures your bars have a crisp, sturdy foundation that won’t get soggy once you add the toppings.
Step 4: Add Chocolate and Marshmallows
Remove the pan from the oven and immediately sprinkle the chocolate chips evenly over the warm crust. Then, generously top with mini marshmallows. The heat from the crust will start softening the chocolate, creating that gooey melt we all love.
Step 5: Final Bake for Toasted Perfection
Pop the bars back in the oven for about 20 minutes or until the marshmallows are beautifully puffed and browned on top. Keep an eye on them—perfectly toasted marshmallows are key to achieving that authentic campfire flavor.
Step 6: Cool and Chill
Once baked, allow your S’more Bars to cool at room temperature before placing them in the fridge. Chilling helps them firm up, making each bar easier to cut and serve without falling apart.
Step 7: Cut and Enjoy
Slice your chilled bars into squares or rectangles and get ready to indulge in this dreamy, chocolate-marshmallow-filled treat that’s perfect for sharing or savoring as a solo snack.
How to Serve S’more Bars

Garnishes
While these bars are stunning on their own, a light dusting of powdered sugar or a drizzle of caramel sauce adds an elegant touch. For a fresh contrast, sprinkle chopped nuts like toasted almonds or a pinch of flaky sea salt on top right after baking to elevate the flavor dimension.
Side Dishes
S’more Bars pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream to balance the richness. Fresh berries or sliced bananas work beautifully to add a hint of freshness and a pop of color to your dessert plate.
Creative Ways to Present
For a party or picnic, arrange your S’more Bars on a rustic wooden board garnished with sticks of graham crackers and mini marshmallows around the edges—inviting your guests to snack and reminisce together. You can also cut them into bite-sized pieces and serve on a dessert platter for easy sharing.
Make Ahead and Storage
Storing Leftovers
Keep any leftover S’more Bars stored in an airtight container in the refrigerator. They will stay fresh and retain their texture for up to 4 days, making them a perfect make-ahead treat.
Freezing
You can freeze the bars by wrapping them tightly in plastic wrap and storing them in a freezer-safe container or bag. When properly frozen, they can last for up to 2 months—just thaw in the fridge overnight before serving.
Reheating
To bring back that just-baked charm, warm your bars gently in the oven at 300 degrees Fahrenheit for about 5-7 minutes, or microwave a single portion for 10-15 seconds until the chocolate softens again.
FAQs
Can I use a different type of chocolate chips?
Absolutely! Feel free to swap semi-sweet chocolate chips for milk, dark, or even white chocolate depending on your preference. Just keep in mind the sweetness level might change slightly.
Is there a way to make these gluten-free?
Yes, just use gluten-free graham cracker crumbs or substitute with crushed gluten-free cookies to keep the crust delicious and safe for those with gluten sensitivities.
Can I add nuts or other mix-ins?
Certainly! Chopped nuts like pecans or walnuts add wonderful crunch, and you can even mix in some peanut butter chips or dried fruit to customize your S’more Bars.
Do I need to refrigerate these bars?
While not absolutely required, refrigeration helps the bars set firmly, making them easier to cut and handle. Plus, it extends their freshness, especially in warm weather.
Can I make these bars vegan?
For a vegan version, use dairy-free butter and chocolate chips, and look for vegan marshmallows to keep the layers just as delightful without animal products.
