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 Your Workspace and Dough Base:

   First things first, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Next, 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 bars out once they’re baked. In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. This step is crucial for developing a tender cookie base, so don’t rush it. You want to incorporate plenty of air into the butter and sugar mixture. Then, beat in the egg and vanilla extract until well combined. Make sure the egg is fully incorporated before moving on.

2. Combine Dry Ingredients and Form the Dough:

   In a separate medium bowl, whisk together the all-purpose flour, finely crushed graham crackers, salt, and baking soda. The crushed graham crackers in the dough add a subtle, authentic s’mores flavor and a delightful texture. Make sure the graham crackers are crushed very finely, almost like breadcrumbs, so they integrate seamlessly into the dough. 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 at this stage; overmixing can lead to tough bars. The dough will be thick and somewhat sticky, which is exactly what we want for a rich cookie bar.

3. Assemble the Layers:

   Now for the fun part – assembling the layers! Spread about two-thirds of the cookie dough evenly into the bottom of your prepared baking pan. Press it down firmly to create an even base. Don’t worry if it’s not perfectly smooth; the bars will spread as they bake. Next, break the 5 standard Hershey bars into pieces and arrange them evenly over the cookie dough base. Try to get them as close to the edges as possible to ensure chocolatey goodness in every bite. The heat from the oven will melt the chocolate, creating gooey pockets throughout the bars. Finally, dollop the marshmallow fluff over the chocolate layer. You don’t need to spread it perfectly; random dollops are fine as it will melt and spread a bit during baking.

4. Top and Bake to Perfection:

   Take the remaining one-third of the cookie dough and crumble it over the marshmallow fluff. This might seem a little messy, but these crumbles will bake into a wonderfully golden-brown topping that adds a delightful texture contrast to the gooey interior. Now, carefully place the pan into your preheated oven. Bake for 25-30 minutes, or until the edges of the cookie dough are golden brown and the marshmallow is puffed and lightly toasted. Keep an eye on your bars during the last few minutes of baking, as ovens can vary. You want the marshmallow to be melted and slightly golden, but not burnt.

5. Cool and Enjoy the S’mores Bliss:

   Once baked, remove the pan from the oven and let the S’mores Cookie Bars cool completely in the pan on a wire rack. This is a critical step! They will be very soft and gooey when they first come out of the oven, and cooling allows them to set up properly. Rushing this process will result in a messy, unmanageable dessert. Once they have cooled down significantly, use the parchment paper overhang to carefully lift the entire slab out of the pan. Then, cut into squares or bars. The anticipation of the cool-down is worth it, as each bite delivers a perfect balance of textures and flavors. These bars are best enjoyed at room temperature, but a brief warming in the microwave can revive any leftover gooeyness if desired. Store any leftovers in an airtight container at room temperature for up to 3 days. Happy baking and even happier eating!

Conclusion:

So there you have it, a foolproof guide to creating the most delicious s’mores cookie bars! These bars are an absolute winner because they capture all the beloved flavors and textures of a classic campfire s’more – the chewy chocolate chip cookie base, the gooey melted marshmallow, and the rich, melty chocolate – all in a convenient, shareable bar. They are incredibly easy to make, perfect for beginners and seasoned bakers alike, and always a guaranteed crowd-pleaser. I’ve found they are fantastic served warm, right out of the oven, with an extra drizzle of chocolate. They also hold up wonderfully for picnics or potlucks. For variations, consider adding a sprinkle of sea salt on top before baking to enhance the chocolate and marshmallow flavors, or even stirring in some chopped nuts like pecans for an extra crunch. Don’t be afraid to experiment with different types of chocolate, like dark or milk chocolate chips, to suit your preference. I truly encourage you to give these s’mores cookie bars a try – I promise you won’t be disappointed!

Frequently Asked Questions about S’mores Cookie Bars:

Q: How should I store leftover s’mores cookie bars?

A: Store your s’mores cookie bars in an airtight container at room temperature for up to 3 days. If you prefer them warmed, you can gently reheat them in a low oven or microwave for a few seconds.

Q: Can I make these s’mores cookie bars ahead of time?

A: Yes! You can prepare the cookie dough and refrigerate it for up to 2 days before assembling and baking. Alternatively, you can bake the bars completely and then freeze them for up to 2 months. Thaw overnight in the refrigerator and warm before serving.

Q: My marshmallows are burning too quickly. What can I do?

A: If your marshmallows are browning too fast, you can cover the pan with foil for the last few minutes of baking to protect them. Another option is to broil them very briefly under a preheated broiler, watching them constantly to prevent burning. Some bakers also find that adding the marshmallow layer towards the end of the baking time helps control the browning.
