Ingredients You’ll Need

To make these S’mores cookie bars, you’ll be reaching for simple pantry staples, but each ingredient plays a crucial role in building that unforgettable flavor and texture. From the tender base to the luscious marshmallow layer, every component brings something special to the table.

• Butter (1/2 cup, softened): Provides rich flavor and helps create a tender, chewy cookie texture.
• Brown sugar (1/3 cup): Adds moisture and a subtle caramel depth that complements the graham crackers perfectly.
• Granulated sugar (1/4 cup): Balances sweetness and helps with that authentic cookie crunch.
• Egg (1): Binds all the ingredients and adds structure to the dough.
• Vanilla extract (1 tsp): Enhances all the flavors with a sweet, aromatic touch.
• All-purpose flour (1½ cups): The base that holds everything together and supports the other ingredients.
• Graham crackers (½ cup, finely crushed): Infuses the cookie dough with the unmistakable classic s’mores flavor and slight crunch.
• Salt (¼ tsp): Balances sweetness and amplifies flavor complexity.
• Baking soda (¾ tsp): Helps the dough rise slightly to keep the bars soft but not cakey.
• Hershey bars (5 standard): Classic milk chocolate that melts into dreamy layers between the cookie dough.
• Marshmallow fluff (1½ cups): Adds that signature gooey, fluffy marshmallow topping that makes s’mores so special.

How to Make S’mores cookie bars

Step 1: Prep Your Tools and Oven

First things first, preheat your oven to 350 degrees Fahrenheit. Line an 8×8 inch baking pan with parchment paper to keep your cookie bars from sticking and to ensure easy removal later. Setting up your pan correctly is a small step that leads to big rewards when it comes to presentation and cleanup.

Step 2: Cream the Butter and Sugars

In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is smooth and well combined. This process helps create that perfectly tender cookie texture. After that, add in the egg and vanilla extract, mixing just until incorporated to keep the dough light and flavorful.

Step 3: Mix in the Dry Ingredients

Now it’s time to add the all-purpose flour, finely crushed graham crackers, salt, and baking soda. Gently fold or mix these dry ingredients into the wet mixture just until you don’t see any flour streaks. Over-mixing can toughen the dough, so keep it light and easy.

Step 4: Create the Cookie Dough Layers

Press half of the cookie dough evenly into the lined baking pan using your hands or a spatula to form a flat base layer. Here’s a neat trick — peel the parchment paper off with the dough still attached and pop it into the freezer to chill. While that’s setting, re-line the pan with fresh parchment and press the remaining cookie dough evenly on the new liner. This double layering technique ensures even baking and a perfect sandwich effect.

Step 5: Add the Chocolate and Marshmallow Layers

Break apart the Hershey bars and spread the chocolate pieces evenly over the second cookie dough layer in the baking pan. Next, spread the marshmallow fluff generously on top of the chocolate. The fluffy layer is going to melt and create that irresistible gooey center that shines in S’mores cookie bars.

Step 6: Assemble and Bake

Carefully take the chilled first cookie dough layer out of the freezer. Gently flip and place it on top of the marshmallow layer, pressing lightly to seal the edges. Bake the whole pan in your preheated oven for 25 minutes. Once baked, patience is key—let the bars cool completely for clean slicing and to let all those flavors settle beautifully.

How to Serve S’mores cookie bars

Garnishes

For a little extra wow factor, consider sprinkling some crushed graham crackers or mini marshmallows on top of the cooled bars before serving. A light drizzle of melted chocolate can also elevate the look and add an artistic touch to your presentation without overwhelming those classic flavors.

Side Dishes

These bars are quite the treat on their own, but pairing them with a scoop of vanilla ice cream or a dollop of whipped cream truly takes it up a notch. If you’re serving these bars at a party, some fresh berries on the side can add a refreshing, fruity contrast that balances the richness.

Creative Ways to Present

Try cutting the bars into bite-sized squares and serving them on a platter with skewers to mimic mini s’mores bites. Or wrap individual bars in cute parchment paper and tie with twine for an adorable gift idea or party favor that friends and family will rave about.

Make Ahead and Storage

Storing Leftovers

Once cooled, store your S’mores cookie bars in an airtight container at room temperature for up to 3 days. This keeps the cookies soft, the chocolate melty, and the marshmallow fluff delightfully gooey, just as they should be.

Freezing

If you want to keep these bars fresh for longer, freezing is a fantastic option. Wrap individual bars tightly in plastic wrap and place them in a freezer-safe bag or container. They’ll keep well for up to 2 months and remain just as delicious once thawed.

Reheating

For that freshly baked taste, warm frozen or refrigerated bars in the microwave for 15 to 20 seconds or briefly in an oven preheated to 300°F until slightly warm. This revives the gooey marshmallow and melty chocolate without drying the cookie base.

FAQs

Can I use different chocolate types in S’mores cookie bars?

Absolutely! While classic milk chocolate works beautifully, feel free to experiment with dark chocolate, white chocolate, or even chocolate chips to customize your bars to your taste.

Is it necessary to chill the cookie dough layer before assembling?

Chilling the first dough layer helps create stability when flipping it over the marshmallow layer. It makes handling much easier and prevents the dough from tearing or sticking too much.

Can I substitute marshmallow fluff with regular marshmallows?

You can, but the texture will be different. Marshmallow fluff spreads smoothly, creating an even gooey layer, while mini marshmallows will melt unevenly and might not create the same creamy effect.

How do I cut S’mores cookie bars without making a mess?

Using a sharp knife wiped clean between cuts is key. Make sure the bars are fully cooled to help keep the layers intact and your slices neat.

Can I make these bars gluten-free?

Yes! Substitute the all-purpose flour with a gluten-free flour blend, and use gluten-free graham crackers. The texture may vary slightly but the flavors will still be scrumptious.

Final Thoughts

If you’re looking for a treat that brings campfire nostalgia right into your kitchen, these S’mores cookie bars are a must-try.
