S’mores Cookie Bars Recipe

Introduction

These S’mores cookie bars combine the nostalgic flavors of classic campfire treats into an easy-to-make dessert. Layers of graham cracker cookie dough, melted chocolate, and fluffy marshmallow create a gooey, irresistible bar perfect for any occasion.

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)
• 1/4 tsp salt
• 3/4 tsp baking soda
• 5 standard Hershey bars
• 1 1/2 cups marshmallow fluff

Instructions

1. Step 1: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper and set aside.
2. Step 2: Cream together the softened butter, granulated sugar, and brown sugar until well combined. Add the egg and vanilla extract, mixing thoroughly.
3. Step 3: In a separate bowl, combine the flour, crushed graham crackers, salt, and baking soda. Gradually add this dry mixture to the wet ingredients, mixing just until the flour disappears.
4. Step 4: Press half of the cookie dough evenly into the prepared pan. Carefully remove the parchment paper with the dough and place it in the freezer. Re-line the pan with fresh parchment and press the remaining dough into it as well.
5. Step 5: Arrange the Hershey bars evenly over the dough in the pan, breaking pieces if needed to cover the surface. Spread marshmallow fluff evenly over the chocolate layer. Then, gently take the chilled dough layer from the freezer and flip it on top of the marshmallow layer, handling carefully to keep it intact.
6. Step 6: Bake for 25 minutes in the preheated oven. Allow the bars to cool completely before slicing to see the gooey layers clearly.

Tips & Variations

• Use regular or mini marshmallows instead of marshmallow fluff for a different texture.
• Try substituting the Hershey bars with your favorite chocolate, such as milk, dark, or even peanut butter cups.
• For a crunchier crust, chill the dough layers longer before assembling and baking.
• Add a pinch of cinnamon or espresso powder to the dough for subtle flavor depth.

Storage

Store the s’mores cookie bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them covered in the refrigerator for up to one week. Reheat gently in the microwave for 10-15 seconds if you prefer them warm and gooey.

FAQs

Can I use salted butter or unsalted butter?

Either salted or unsalted butter works for this recipe. If using salted butter, omit adding extra salt; if using unsalted, keep the 1/4 teaspoon of salt as directed.

Why do I need to freeze one dough layer before assembling?

Freezing the first cookie dough layer helps make it firm enough to flip over the marshmallow and chocolate layers without breaking, ensuring clean layers and an even bar.

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

Layer Toppings

• 5 standard Hershey bars
• 1 1/2 cup Marshmallow fluff

Instructions

1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and set aside for later use.
2. Cream 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. Then add in the egg and vanilla extract, mixing thoroughly until well incorporated.
3. Add Dry Ingredients: Gradually add the all-purpose flour, finely crushed graham cracker crumbs, salt, and baking soda straight into the butter mixture. Mix just until the flour disappears and the dough comes together, being careful not to overmix.
4. Form First Cookie Layer: Press half of the cookie dough evenly into the prepared baking pan. Carefully remove the parchment paper with the dough attached from the pan and place it in the freezer to chill while you prepare the next layer.
5. Prepare Second Cookie Layer: Re-line the baking pan with fresh parchment paper. Press the remaining half of the cookie dough evenly into this lined pan to form the second layer.
6. Add Chocolate and Marshmallow Layers: Place the Hershey bars over the second cookie dough layer, breaking them into pieces if necessary to cover the surface completely. Spread the marshmallow fluff evenly over the chocolate bars.
7. Assemble Bars: Remove the chilled first cookie dough layer from the freezer and carefully flip it on top of the marshmallow-topped chocolate layer. Work gently to avoid breaking the dough layer.
8. Bake: Bake the assembled cookie bars in the preheated oven for 25 minutes until golden and cooked through.
9. Cool and Slice: Allow the bars to cool completely in the pan before slicing to achieve clean bars with a beautiful cross-section of all layers.

Notes

• Using parchment paper helps to easily remove the bars from the pan after baking.
• Freezing the first dough layer helps it hold its shape when flipped on top of the marshmallow and chocolate layers.
• Feel free to substitute Hershey bars with your favorite chocolate for variation.
• Allow adequate cooling time to prevent the marshmallow layer from sticking or oozing out when sliced.
• Store leftover bars in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
