Ingredients:

For the Cookie Base:

1 cup (2 sticks) unsalted butter, softened
¾ cup granulated sugar
¾ cup packed brown sugar
2 large eggs
1 teaspoon vanilla extract
2 ¼ cups all-purpose flour
1 teaspoon baking soda
1 teaspoon salt

For the Marshmallow Layer:

1 (10 ounce) bag of large marshmallows
2 tablespoons butter
1 teaspoon vanilla extract

For the Chocolate Topping:

12 ounces semi-sweet chocolate chips
2 tablespoons vegetable oil (or coconut oil)
1 cup graham cracker crumbs (about 14 graham cracker squares)

Preparing the Cookie Base:

Cream the Butter and Sugars: In a large bowl, or the bowl of a stand mixer fitted with the paddle attachment, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This usually takes about 3-5 minutes. Make sure to scrape down the sides of the bowl occasionally to ensure everything is evenly mixed. The mixture should be pale and airy. This step is crucial for a tender cookie base.
Add the Eggs and Vanilla: Beat in the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract. Ensure the eggs are fully incorporated before adding the next one to prevent curdling. The vanilla extract enhances the overall flavor of the cookie bars.
Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt. Whisking ensures that the baking soda and salt are evenly distributed throughout the flour, which is important for proper leavening and flavor.
Gradually Add Dry Ingredients to Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix, as this can result in a tough cookie base. Overmixing develops the gluten in the flour, leading to a less tender texture. Stop mixing as soon as the flour disappears.
Press into Baking Pan: Press the cookie dough evenly into a greased and lightly floured 9x13 inch baking pan. You can use your fingers or the back of a spoon to spread the dough. Make sure the dough is evenly distributed to ensure even baking. A slightly damp hand can help prevent the dough from sticking to your fingers.
Bake the Cookie Base: Bake in a preheated oven at 350°F (175°C) for 18-22 minutes, or until the edges are golden brown and the center is set. The cookie base should be slightly underbaked, as it will continue to cook while the marshmallow layer is added. Keep a close eye on it to prevent burning.

Making the Marshmallow Layer:

Melt the Butter: While the cookie base is baking, prepare the marshmallow layer. In a large, microwave-safe bowl, melt the 2 tablespoons of butter. You can also do this in a saucepan over low heat. Be careful not to burn the butter.
Add Marshmallows: Add the bag of large marshmallows to the melted butter. Stir to coat the marshmallows in the butter.
Microwave Marshmallows: Microwave on high for 1-2 minutes, stirring every 30 seconds, until the marshmallows are melted and smooth. Be careful, as the marshmallows will puff up and can overflow. Watch them closely and stop the microwave if necessary.
Stir in Vanilla: Stir in the vanilla extract to the melted marshmallow mixture. This adds a nice depth of flavor to the marshmallow layer.
Spread Marshmallow Layer: Once the cookie base is done baking, immediately remove it from the oven and spread the melted marshmallow mixture evenly over the hot cookie base. Work quickly, as the marshmallows will start to set as they cool.

Creating the Chocolate Topping:

Melt the Chocolate: In a microwave-safe bowl, combine the semi-sweet chocolate chips and vegetable oil (or coconut oil). Microwave in 30-second intervals, stirring in between, until the chocolate is completely melted and smooth. The oil helps to create a glossy and smooth chocolate topping.
Spread Chocolate Over Marshmallows: Pour the melted chocolate evenly over the marshmallow layer. Use a spatula to spread the chocolate to the edges of the pan.
Sprinkle with Graham Cracker Crumbs: Immediately sprinkle the graham cracker crumbs evenly over the melted chocolate. The graham cracker crumbs add a classic s'mores flavor and a nice textural contrast.
Chill and Set: Place the baking pan in the refrigerator for at least 1-2 hours, or until the chocolate is completely set. This will make it easier to cut the bars cleanly.

Cutting and Serving:

Cut into Bars: Once the chocolate is set, remove the baking pan from the refrigerator. Use a sharp knife to cut the s'mores cookie bars into squares. For cleaner cuts, you can run the knife under hot water and wipe it dry between each cut.
Serve and Enjoy: Serve the s'mores cookie bars immediately or store them in an airtight container at room temperature for up to 3 days. They are best enjoyed fresh, when the cookie base is still slightly soft and the marshmallow is gooey.

Tips for Success:

Don't Overbake the Cookie Base: An underbaked cookie base is better than an overbaked one, as it will continue to cook while the marshmallow layer is added.
Work Quickly with the Marshmallow Layer: The melted marshmallows will start to set quickly, so spread them over the cookie base as soon as possible.
Use High-Quality Chocolate: The quality of the chocolate will greatly impact the flavor of the s'mores cookie bars. Use a good quality semi-sweet chocolate for the best results.
Customize Your Toppings: Feel free to add other toppings to the chocolate layer, such as chopped nuts, mini marshmallows, or a drizzle of caramel sauce.
For a Gooier Marshmallow Layer: If you prefer a gooier marshmallow layer, you can broil the marshmallow layer for a few seconds after spreading it over the cookie base. Watch it closely to prevent burning.

Variations:

Peanut Butter S'mores Cookie Bars: Add ½ cup of peanut butter to the cookie dough for a peanut butter twist.
Dark Chocolate S'mores Cookie Bars: Use dark chocolate chips instead of semi-sweet chocolate chips for a richer flavor.
Salted Caramel S'mores Cookie Bars: Drizzle caramel sauce over the chocolate layer and sprinkle with sea salt for a salted caramel flavor.
Nutella S'mores Cookie Bars: Swirl Nutella into the melted marshmallow layer for a hazelnut chocolate flavor.
