Ingredients You'll Need
These ingredients are simple but essential to nailing that perfect balance of taste and texture in your Easy S'mores Cookie Bars Recipe. Each component adds something special, from creamy sweetness to delightful crunch.
- Chocolate chip cookie dough: Using pre-made dough saves time while giving you that chewy cookie base that's full of buttery flavor.
- Milk or dark chocolate chips: These melt beautifully to add rich pockets of chocolate throughout.
- Graham cracker crumbs: The crumbs provide that signature crunch and slight toastiness reminiscent of classic s’mores.
- Marshmallow fluff/creme: Gooey and sweet, fuzzing the bars with that perfect marshmallow melting sensation.
How to Make Easy S'mores Cookie Bars Recipe
Step 1: Prep Your Ingredients
First things first, take your pre-made chocolate chip cookie dough out of the refrigerator and let it sit for 10 to 15 minutes until it reaches room temperature. This helps the dough soften so it’s easier to press into the pan without tearing. Also, line a 9x9-inch baking pan with parchment paper and preheat your oven to 350 degrees Fahrenheit. This sets the stage for a perfect bake.
Step 2: Press the Cookie Dough Base
Take about half of your cookie dough and spread it evenly into the bottom of the prepared pan. It’s best to use your fingers to gently press the dough into a smooth, uniform layer without gaps. This base will hold all your s’more goodness together, so make sure it’s solid and even.
Step 3: Sprinkle the Chocolate
Scatter your milk or dark chocolate chips evenly across the cookie dough base. You want the bars to be studded with chocolatey jewels, so spread the chips out generously so every bite has melty chocolate surprises.
Step 4: Add the Graham Cracker Crumbs
Next, sprinkle a layer of graham cracker crumbs over the chocolate chips. This adds crunch and that unmistakable hint of graham flavor that’s crucial for a true s’mores experience.
Step 5: Spread on the Marshmallow Fluff
Scoop the marshmallow fluff on top of that graham cracker layer and use a spatula sprayed with nonstick spray to spread it evenly. This sticky layer will melt into gooey clouds during baking, creating that luscious marshmallow texture we all love.
Step 6: Top with Remaining Cookie Dough
Now, take the remaining cookie dough, flatten it gently between your fingers, and place it in rows on top of the marshmallow layer. Don’t worry if some marshmallow peeks through—this is exactly what you want. It lets the marshmallow bubble up and caramelize around the edges as it bakes.
Step 7: Bake to Perfection
Bake your assembled bars for 25 to 30 minutes until the cookie dough sets and turns a beautiful golden brown. Keep an eye on them during the last 10 minutes to prevent the marshmallow or edges from burning. The smell while they bake is seriously irresistible.
Step 8: Cool and Cut
Once baked, allow your Easy S'mores Cookie Bars Recipe to cool completely in the pan for at least two hours. This step lets the layers firm up so they’ll cut cleanly into 16 squares without falling apart. Use a sharp knife and get ready to enjoy!
How to Serve Easy S'mores Cookie Bars Recipe
Garnishes
For a fun touch, sprinkle a little extra graham cracker crumbs or mini chocolate chips on top before serving. You can even drizzle melted chocolate or a little caramel sauce to amp up the decadence. Adding a few toasted mini marshmallows just before serving can add a fresh campfire vibe too.
Side Dishes
These cookie bars pair beautifully with simple sides like a tall glass of cold milk or a scoop of vanilla ice cream to contrast the rich, gooey texture. Fresh berries can add a nice bright pop to balance sweetness. They’re also great alongside hot coffee or tea for a cozy snack break.
Creative Ways to Present
Serve the bars on a rustic wooden platter with skewers of toasted marshmallows to bring that real s’mores atmosphere indoors. You can cut them into bite-decorated mini squares for parties, or stack a few layers with whipped cream for a fun dessert tower. The options are endless and always delicious!
Make Ahead and Storage
Storing Leftovers
Store any leftover Easy S'mores Cookie Bars Recipe in an airtight container at room temperature for up to three days. Keeping them sealed helps maintain that soft cookie texture while preventing the marshmallow from drying out or getting sticky on the surface.
Freezing
If you want to save some for later, these bars freeze beautifully. Wrap individual squares tightly in plastic wrap and place them in a freezer-safe container or ziplock bag. They’ll keep well frozen for up to two months and thaw quickly at room temperature.
Reheating
To enjoy your cookie bars warm, reheat individual squares in the microwave for about 15-20 seconds until the chocolate softens and the marshmallow gets gooey again. You can also briefly warm them in a preheated oven at 300 degrees Fahrenheit for 5 to 7 minutes, just watch that they don’t burn.
FAQs
Can I make this recipe with homemade cookie dough?
Absolutely! Homemade cookie dough works just as well and adds an extra layer of personalization to your bars. Just make sure the dough is soft enough to spread evenly in the pan.
What chocolate is best for melting in these bars?
Milk chocolate chips melt smoothly and taste sweet, but dark chocolate offers a rich contrast to the sweet marshmallow. You can even mix both for a deliciously complex flavor.
Is it possible to make this gluten-free?
Yes! Using gluten-free cookie dough and gluten-free graham cracker crumbs will give you the same delicious Easy S'mores Cookie Bars Recipe that everyone can enjoy without losing any of the flavor.
Can I substitute marshmallow fluff with mini marshmallows?
You can, but marshmallow fluff spreads more evenly which helps keep the bars intact. If using mini marshmallows, scatter them generously and watch carefully during baking to avoid burning.
How long should I let the bars cool before cutting?
Cooling for at least two hours is key to letting the layers set properly, which makes cutting easier and mess-free. If you’re impatient, a minimum of one hour can work but expect softer edges.

- Method: Baking
- Cuisine: American
Ingredients
Cookie Base
- 2-3 packages pre-made chocolate chip cookie dough (about 16-24 oz total)
Layers
- 2 cups milk chocolate chips or dark chocolate chips (or 3 Hershey's chocolate bars, chopped)
- 1 cup graham cracker crumbs
- 2 cups marshmallow fluff/creme
Instructions
- Prep: Remove the chocolate chip cookie dough from the fridge and let it sit at room temperature for 10-15 minutes to soften. If frozen, thaw first. Line a 9x9 inch square baking pan with parchment paper and preheat the oven to 350°F (175°C).
- Press Dough Base: Press half of the cookie dough into an even single layer at the bottom of the prepared pan. Use your fingers to ensure there are no gaps and the dough covers the entire base thoroughly.
- Layer Chocolate: Sprinkle the chocolate chips evenly over the cookie dough layer, distributing them so the base is almost covered with chocolate.
- Add Graham Crackers: Crumble the graham crackers and sprinkle the crumbs evenly over the chocolate layer.
- Spread Marshmallow Fluff: Scoop the marshmallow fluff over the graham cracker layer and spread into an even layer using a spatula. Spray the spatula lightly with nonstick spray to prevent sticking if necessary.
- Top with Remaining Dough: Roll or press the remaining cookie dough into thin strips or small pieces and arrange them evenly over the marshmallow layer. It’s okay if some marshmallow shows through, as this allows it to seep through during baking, creating a gooey top.
- Bake: Bake in the preheated oven for 25-30 minutes, until the cookie bars are set and the edges are lightly golden brown. Monitor closely in the last 10 minutes to avoid burning, especially the marshmallow layer.
- Cool and Serve: Allow the bars to cool completely for at least 2 hours so they set well. Use a sharp knife to cut into 16 squares and serve.
Notes
- Using room temperature cookie dough makes it easier to press and shape the layers.
- Spraying the spatula when spreading marshmallow fluff prevents sticking and helps create an even layer.
- Cooling the bars thoroughly before cutting ensures clean squares and prevents the layers from falling apart.
