Ingredients

Scale

Cookie Dough

1 cup unsalted butter, softened
1 cup brown sugar, packed
0.5 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
2.5 cups all-purpose flour
1 teaspoon baking soda
0.5 teaspoon salt
1 cup graham cracker crumbs
1 cup semi-sweet chocolate chips

Filling

1.5 cups milk chocolate spread
2 cups mini marshmallows

Instructions

Preheat and Prepare: Preheat your oven to 350°F (175°C) and line a 9×13-inch baking dish with parchment paper to prevent sticking and ensure easy removal.
Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light, fluffy, and well combined, providing a perfect base for the cookie dough.
Add Eggs and Vanilla: Beat in the eggs one at a time, mixing thoroughly after each addition to maintain a smooth texture. Stir in the vanilla extract to enhance the flavor.
Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, salt, and graham cracker crumbs, ensuring these ingredients are evenly combined for consistent texture.
Combine Wet and Dry Mixtures: Gradually incorporate the dry ingredients into the wet mixture, mixing just until combined to avoid overworking the dough. Fold in the semi-sweet chocolate chips evenly.
Form Bottom Layer: Press half of the cookie dough evenly into the prepared baking dish, creating a solid base layer for the s’mores bars.
Add Chocolate Spread and Marshmallows: Spread the milk chocolate spread evenly over the cookie dough base, then sprinkle the mini marshmallows evenly on top to create the gooey s’mores center.
Top with Remaining Dough: Flatten the remaining cookie dough into pieces and gently place them over the marshmallow layer, covering as much as possible to seal the filling.
Bake the Bars: Bake in the preheated oven for 25 to 30 minutes, or until the top is golden brown. Keep an eye to prevent overbaking, which could dry out the bars.
Cool and Serve: Allow the bars to cool completely in the baking dish before slicing into squares. This cooling step helps the bars set for clean cutting and optimal texture.

Notes

Ensure the butter is softened but not melted to achieve the ideal creaming texture.
Do not overmix the dough when adding dry ingredients to maintain a tender crumb.
Use parchment paper to easily lift the bars from the pan without breaking.
For extra gooey marshmallows, add more mini marshmallows in the middle layer.
Store leftovers in an airtight container at room temperature for up to 3 days or freeze for longer storage.
