The best part about this recipe is how simple and straightforward the ingredients are—each one plays a crucial role in delivering the perfect blend of textures and flavors. These pantry staples come together effortlessly to bring you a treat that’s both nostalgic and indulgent.
- Graham cracker crumbs: The crunchy and slightly sweet base that forms the perfect crust.
- Unsalted butter (melted): Helps bind the crust while adding richness and moisture.

How to Make S’mores Bars Recipe
Step 1: Prep Your Oven and Pan
First things first, preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish. This sets the stage for a smooth baking process and prevents your bars from sticking, making cleanup easier too!
Step 2: Mix the Crust
In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Stir everything together until the crumbs are evenly coated and the mixture holds together when pressed. This step is key for that crumbly yet sturdy base.
Step 3: Press the Crust Into the Pan
Take your graham cracker crumb mixture and firmly press it into the bottom of the prepared baking dish. Aim for a nice, even layer—it’s the foundation of your S’mores Bars, so give it some love by pressing down evenly.
Step 4: Layer the Chocolate
Break the Hershey’s chocolate bars into small pieces and scatter them evenly over the crust. The chocolate will melt into a luscious layer that perfectly complements the crunchy base and marshmallows.
Step 5: Add the Marshmallows
Sprinkle the mini marshmallows in a generous, even layer on top of the chocolate. These little guys will toast beautifully in the oven, adding that perfect gooey, golden finish.
Step 6: Bake Until Golden and Gooey
Pop the dish into your preheated oven and bake for 10 to 12 minutes, or until the marshmallows turn golden brown and the chocolate has melted. Keep an eye on them—they can go from perfect to toasted very quickly!
Step 7: Cool Before Cutting
Once baked, carefully remove your pan from the oven. Let the S’mores Bars cool for about 15 to 20 minutes. This resting period allows the layers to set, which makes cutting them into neat squares a breeze.
Step 8: Slice and Enjoy!
After cooling, slice the bars into your desired size, serve, and watch as everyone dives into these chewy, crunchy, chocolatey delights. The perfect treat is ready!
How to Serve S’mores Bars Recipe

Garnishes
Want to elevate your presentation? Try sprinkling a pinch of crushed graham crackers on top or drizzling a little melted chocolate over each bar. For a playful twist, add a few toasted marshmallows right before serving for extra gooeyness and visual appeal.
Side Dishes
Complement these bars with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent experience. A tall glass of cold milk or even a cup of hot cocoa also pairs beautifully, balancing the sweetness with creamy refreshment.
Creative Ways to Present
Serve the bars on a rustic wooden board for a cozy vibe, or pack them into colorful paper bags for a delightful picnic treat. For parties, arrange them on a tiered dessert stand to make your S’mores Bars the centerpiece everyone can’t stop talking about.
Make Ahead and Storage
Storing Leftovers
Store any leftover S’mores Bars in an airtight container at room temperature for up to 3 days. This keeps them fresh while maintaining that perfect chewy texture without the marshmallows turning hard.
Freezing
To keep your S’mores Bars longer, freeze them by wrapping each bar individually in plastic wrap and placing them in a freezer-safe container. They’ll keep well for up to 2 months, making a great ready-to-go snack whenever a craving strikes.
Reheating
If you want to revive the gooey, melty sensation, simply warm the bars in the microwave for 10-15 seconds or pop them into a preheated oven at 300°F for about 5 minutes. This softens the marshmallows and chocolate, bringing out that just-baked magic.
FAQs
Can I use different chocolate bars for this recipe?
Absolutely! While Hershey’s chocolate bars give the classic taste, feel free to experiment with milk chocolate, dark chocolate, or even peanut butter cups to create your own twist on the S’mores Bars Recipe.
Is it possible to make this gluten-free?
Yes! Just swap the graham cracker crumbs for a gluten-free alternative to keep the crust delicious and safe for those with gluten sensitivities without sacrificing texture or flavor.
Can I use large marshmallows instead of mini ones?
Using large marshmallows works, but you may want to chop them into smaller pieces to ensure even coverage and melting. The mini marshmallows create that perfect gooey top layer more consistently.
How long do these bars last once baked?
Once baked and stored properly in an airtight container, these S’mores Bars will stay fresh and tasty for about 3 days at room temperature.
Can I double the recipe for a larger batch?
You can definitely double the recipe! Just use a larger baking dish or two pans, and keep an eye on the baking time—it may vary slightly depending on your oven and pan size.
