S’mores Cookie Bars Recipe

Introduction

S’mores cookie bars combine the classic flavors of campfire s’mores into a convenient, delicious dessert you can enjoy anytime. With layers of graham cracker cookie, melted chocolate, and gooey marshmallow fluff, they’re perfect for sharing or indulging on your own.

Ingredients

• 1/2 cup butter (softened, salted or unsalted)
• 1/3 cup brown sugar
• 1/4 cup granulated sugar
• 1 egg
• 1 tsp vanilla extract
• 1 1/2 cups all-purpose flour
• 1/2 cup graham crackers (finely crushed, about 3.5 sheets, for the cookie dough)
• 1/4 tsp salt
• 3/4 tsp baking soda
• 5 standard Hershey bars
• 1 1/2 cups marshmallow fluff

Instructions

1. Step 1: Preheat the oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and set it aside.
2. Step 2: Cream the butter, granulated sugar, and brown sugar together until combined. Add in the egg and vanilla extract, mixing again until smooth.
3. Step 3: Stir in the flour, graham cracker crumbs, salt, and baking soda. Mix just until the flour mixture disappears and the dough comes together.
4. Step 4: Press half of the dough evenly onto the prepared baking pan. Carefully remove the parchment with the dough from the pan and place it in the freezer. Reline the pan with fresh parchment and press the remaining dough evenly onto it.
5. Step 5: Arrange the chocolate bars over the dough, breaking pieces if needed to cover the surface completely. Spread the marshmallow fluff evenly over the chocolate layer.
6. Step 6: Gently flip the chilled dough layer from the freezer on top of the marshmallow fluff, taking care to keep it intact.
7. Step 7: Bake in the preheated oven for 25 minutes. Let the bars cool completely before slicing to reveal the layered cross section.

Tips & Variations

• For a nutty twist, add 1/2 cup chopped toasted nuts like pecans or walnuts to the dough before baking.
• If you prefer darker chocolate, swap Hershey bars for semi-sweet or bittersweet chocolate bars.
• Use regular mini marshmallows instead of marshmallow fluff for a slightly different texture.
• Chilling the dough layer helps prevent the bars from falling apart when flipping — don’t skip this step.

Storage

Store the s’mores cookie bars in an airtight container at room temperature for up to 3 days. They can also be refrigerated for up to a week; bring to room temperature before serving. To reheat, warm gently in a microwave for 10–15 seconds to soften the marshmallow layer.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I make these bars gluten-free?

Yes, substitute the all-purpose flour with a gluten-free baking blend that measures cup-for-cup for best results. Make sure graham crackers used are gluten-free as well.

Can I freeze the s’mores cookie bars?

Absolutely. Wrap individual bars tightly in plastic wrap and store in a freezer-safe container for up to 2 months. Thaw at room temperature before enjoying.

Ingredients

Scale 1x2x3x

Cookie Dough

• 1/2 cup Butter (softened, salted or unsalted)
• 1/3 cup Brown sugar
• 1/4 cup Granulated sugar
• 1 Egg
• 1 tsp Vanilla extract
• 1 1/2 cup All-purpose flour
• 1/2 cup Graham crackers (finely crushed, about 3.5 sheets)
• 1/4 tsp Salt
• 3/4 tsp Baking soda

Filling

• 5 Standard Hershey bars (milk chocolate)
• 1 1/2 cup Marshmallow fluff

Instructions

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and set it aside for the cookie dough.
2. Cream Butter and Sugars: In a mixing bowl, cream together softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy. This helps create a tender cookie base.
3. Add Egg and Vanilla: Beat in the egg and vanilla extract until fully combined, ensuring a smooth batter.
4. Mix Dry Ingredients: In a separate bowl, combine all-purpose flour, finely crushed graham crackers, salt, and baking soda. Gradually add this dry mixture to the wet ingredients, mixing just until the flour disappears to avoid overworking the dough.
5. Prepare the Bottom Cookie Layer: Press half of the cookie dough evenly into the prepared baking pan. Carefully remove the parchment paper with the dough from the pan and place it in the freezer to chill. Meanwhile, re-line the pan with fresh parchment paper.
6. Prepare the Top Cookie Layer: Press the remaining cookie dough evenly onto the new parchment-lined pan and chill it as well.
7. Assemble the S’mores Bars: On top of the cookie layer in the pan, arrange the Hershey bars, breaking them into pieces if needed to cover the surface completely. Spread the marshmallow fluff evenly over the chocolate layer.
8. Add the Top Cookie Layer: Remove the chilled bottom dough from the freezer and carefully flip it over onto the marshmallow layer, gently pressing to keep it intact.
9. Bake: Place the assembled bars in the preheated oven and bake for 25 minutes. This allows the cookies to cook through and the chocolate to melt perfectly.
10. Cool and Serve: Let the S’mores cookie bars cool completely before slicing to maintain the layers and enjoy the gooey texture.

Notes

• Using parchment paper makes it easier to remove the cookie bars from the pan without breaking.
• Chilling the cookie dough layers is key to handling and assembling without them falling apart.
• Feel free to substitute the Hershey bars with any milk or dark chocolate bars of your choice.
• For a crunchier texture, bake a few minutes longer, but watch closely to prevent burning.
• Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
