Ingredient Notes & Substitutions

• Butter: Softened butter is key for a smooth, creamy cookie dough. Use either salted or unsalted; if using unsalted, a tiny pinch more salt can enhance the flavor.
• Brown Sugar & Granulated Sugar: The combination gives the bars chewiness from the brown sugar and a delicate crispness from the granulated sugar. Don’t skip either!
• Graham Crackers: Finely crushed graham crackers are incorporated directly into the cookie dough for that authentic s’mores flavor throughout. About 3.5 sheets should give you the right amount.
• Hershey Bars: Standard Hershey bars melt beautifully and provide that quintessential s’mores chocolate flavor. You can break them to fit your pan perfectly.
• Marshmallow Fluff: This is what gives you that wonderfully gooey, sticky marshmallow layer. It spreads easily and stays soft.

How to Make It

First, you’ll want to get your oven preheated to 350°F and prepare an 8×8 inch baking pan by lining it with parchment paper. This parchment paper is crucial for easy removal and clean-up later.

Next, you’ll whip up the cookie dough. Start by creaming together the softened butter, brown sugar, and granulated sugar until it’s light and fluffy. Then, incorporate the egg and vanilla extract, mixing them in well. Finally, add your dry ingredients: flour, finely crushed graham crackers, salt, and baking soda, mixing just until the flour disappears. Be careful not to overmix!

The assembly is a bit unique but ensures a perfect bar. You’ll press half of the dough into the prepared pan, then remove that parchment with the dough and pop it into the freezer to chill. While it’s chilling, re-line your pan and repeat the process with the remaining dough. Once the first dough layer is firm, you’ll layer the Hershey bars and marshmallow fluff on top, then gently flip the chilled cookie dough layer on top to create a sandwich. Bake for 25 minutes, and remember the golden rule: let them cool completely before slicing for clean, beautiful bars!

Tips for Best Results

• Ensure your butter is truly softened for a smooth, lump-free dough.
• Don’t overmix the cookie dough once the dry ingredients are added; mix just until combined.
• Finely crush the graham crackers so they blend seamlessly into the dough.
• Chilling the cookie dough layers helps them firm up, making them easier to handle for assembly.
• Allow the bars to cool completely before cutting to prevent a gooey, crumbly mess and achieve neat slices.
• Use parchment paper for easy removal and to prevent sticking.

Common Mistakes to Avoid

• Overmixing the dough: This develops the gluten too much, leading to tough, not tender, cookie bars. Mix just until the flour streaks disappear.
• Not chilling the dough layers: The chilling step firms up the dough, making it much easier to transfer and assemble the top layer without breaking.
• Cutting the bars while warm: The chocolate and marshmallow will be molten, making them impossible to cut cleanly. Always wait until fully cooled.
• Forgetting to line the pan: Without parchment paper, the gooey s’mores bars will stick, making removal difficult and messy.

How to Store & Make Ahead

• Room temperature: Store in an airtight container for up to 3-4 days. The marshmallow may firm up slightly but will still be delicious.
• Freezer: Wrap individual bars tightly in plastic wrap, then place in a freezer-safe bag or container for up to 2-3 months. Thaw at room temperature.

Frequently Asked Questions

What kind of chocolate should I use?

Standard Hershey bars are recommended because they melt beautifully and provide that classic s’mores flavor. You can use milk chocolate, but avoid chocolate chips as they don’t melt as smoothly for this application.

Can I use homemade marshmallow creme instead of fluff?

Yes, you can absolutely use homemade marshmallow creme! Just ensure it’s thick enough to spread without being too runny, as this will affect the texture of the bars.

Why do I need to chill the cookie dough layers?

Chilling the cookie dough layers makes them much firmer and easier to handle when you’re assembling the bars. It prevents the dough from tearing when you try to flip the top layer over the marshmallow and chocolate.

How do I know when the bars are done baking?

The bars are done when the top cookie layer is golden brown and the edges appear set. The center might still look a little soft, but it will firm up as it cools.

These S’mores cookie bars are truly a magical treat, bringing all the fun of a campfire indoors. I hope you give this recipe a try and share the joy with your loved ones. Happy baking!
