These S'mores Cookie Bars are made with a sweet graham cracker crust, cookie dough with marshmallows folded in, and topped with Hershey bar squares for that distinct s'mores taste.
Bake for 18-25 minutes or until top begins to get touches of golden brown. Make sure you bake until the center is set and not jiggly. They will continue to firm up after cooling so be sure not to overbake.
After bars are done baking, remove pan from oven and let sit for about 5 minutes then carefully place broken candy bar pieces on top. Let cool completely before cutting into squares.
