Graham cracker cookie dough is sandwiched with a thick layer of marshmallow fluff and plenty of milk chocolate to create the ultimate s'mores cookie bar! They’re soft, chewy, gooey and don’t require a campfire to make!
Preheat your oven to 350 degrees F and line a 8x8 baking pan with parchment paper to prevent sticking.
In a large bowl, combine softened butter with sugar, egg, and vanilla extract. Mix until smooth, then sprinkle in flour, crushed graham crackers and baking soda. Mix to form a dough.
Add half the dough into your lined 8x8 baking pan. Spread into an even layer and bake at 350 degrees F for 10 minutes. Spread the other half of dough onto a sheet of parchment paper (aiming for a 8x8 square shape) and place in the freezer to chill.
Once the bottom layer is baked, let it cool for 10 minutes.Place the chocolate bars on top, then spread marshmallow fluff on top of the chocolate (this can be sticky but try to make it as even as possible!). Peel the other half of chilled cookie dough off the parchment paper and place on top of the marshmallow layer.
Bake for another 15 minutes. Let the bars cool completely before slicing for best results!
