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 cup AP 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 cup Marshmallow fluff

Instructions:

1. Prepare the Cookie Dough Base:

   In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. This is a crucial step for a tender cookie base, so don’t rush it! A good creaming incorporates air, which will help our bars rise and become wonderfully chewy. Next, beat in the egg and vanilla extract until well combined. In a separate medium bowl, whisk together the all-purpose flour, finely crushed graham crackers, salt, and baking soda. Gradually add the dry ingredients to the wet ingredients, mixing on low speed or by hand until just combined. Be careful not to overmix the dough, as this can lead to tough bars. The crushed graham crackers in the dough add a subtle, authentic s’mores flavor and a delightful texture. You should have a thick, cohesive cookie dough.

2. Assemble the First Layer:

   Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving some overhang on the sides. This will make it super easy to lift the finished bars out of the pan. Press about two-thirds of the cookie dough evenly into the bottom of the prepared pan. You can use your hands, the back of a spoon, or even a piece of parchment paper to get a smooth, even layer. This forms the foundation of our delicious bars.

3. Add the Chocolatey Middle:

   Break the 5 standard Hershey bars into individual squares and arrange them in a single layer over the pressed cookie dough. Try to cover as much of the surface area as possible. As the bars bake, the chocolate will melt into a glorious, gooey layer that is essential for any s’mores experience. If you want an extra chocolatey punch, you can even sprinkle a few extra chocolate chips over the Hershey bars, though it’s not strictly necessary with this generous amount of chocolate.

4. Top with Marshmallow Fluff and Bake:

   Now for the marshmallow magic! Dollop spoonfuls of the marshmallow fluff evenly over the chocolate layer. Gently spread the fluff to cover the chocolate, creating a white, fluffy blanket. It doesn’t have to be perfectly smooth; a slightly rustic look adds to the charm. Press the remaining one-third of the cookie dough in small, irregular pieces over the marshmallow fluff. This creates pockets of chewy cookie throughout the topping, adding another dimension of texture and flavor. Place the pan in the preheated oven and bake for 25-30 minutes, or until the edges are golden brown and the marshmallow topping is lightly toasted. Keep an eye on them, as marshmallows can go from perfectly golden to burnt very quickly!

5. Cool and Slice:

   Once baked, remove the pan from the oven and let the bars cool completely in the pan on a wire rack. This cooling period is essential for the bars to set properly. If you try to cut them too soon, they will be a messy, gooey disaster (though still delicious!). Once completely cool, use the parchment paper overhang to lift the entire block of bars out of the pan. Place it on a cutting board and slice into your desired bar sizes. For a truly celebratory feel, you can even briefly run the top of the bars under the broiler for about 30-60 seconds at the very end of baking (watch them closely!) to get an extra toasty marshmallow layer, mimicking campfire s’mores. Serve and enjoy this decadent treat! These bars are best enjoyed at room temperature, but a quick warm-up in the microwave can revive any leftover gooeyness.

Conclusion:

These S’mores cookie bars are an absolute triumph, offering all the nostalgic joy of campfire s’mores packed into an easy-to-make, crowd-pleasing bar. The perfect balance of chewy cookie base, gooey melted chocolate, and toasted marshmallow topping makes them an irresistible treat for any occasion. They’re incredibly versatile, making them a fantastic option for bake sales, potlucks, or just a cozy night in. I truly encourage you to give this recipe a try; you won’t be disappointed!

For serving, consider them warm right out of the oven for the ultimate gooey experience, or let them cool completely for a firmer, more portable treat. They pair wonderfully with a glass of cold milk or a hot cup of cocoa. Don’t be afraid to experiment with variations! You could add a sprinkle of sea salt on top before baking for a sweet and salty kick, or even swirl in some peanut butter into the cookie dough. Another fun idea is to use different types of chocolate chips, like dark chocolate or milk chocolate chunks, to customize the flavor profile. Enjoy making and devouring these delightful S’mores cookie bars!

Frequently Asked Questions:

Can I make these S’mores cookie bars ahead of time?

Absolutely! These bars are excellent for making ahead. Once completely cooled, store them in an airtight container at room temperature for up to 3 days. You can even gently reheat them in a low oven or microwave for a few seconds to revive their gooeyness.

What is the best way to toast the marshmallows evenly?

For the most even toasting, you can use your oven’s broiler. Keep a very close eye on them, as they can go from perfectly golden to burnt in seconds. Alternatively, a kitchen torch offers precise control for that ideal toasted finish. Some people even find success placing them under a grill for a quick toast.

Can I use graham cracker crumbs in the cookie dough?

That’s a fantastic idea for an extra layer of s’mores flavor! You could substitute a portion of the flour with finely crushed graham crackers, or even add a layer of graham cracker crumbs at the bottom of your baking pan before adding the cookie dough. This would enhance the S’mores cookie bars experience even further.
