Line a baking sheet with parchment paper and preheat oven to 325 degrees. Prep cookies by stacking half a graham cracker on the bottom, then the chocolate on top (one Reese's cup or 3-4 chocolate squares), followed by one marshmallow.

Take your premade cookie dough and scoop a large ball, about the size of an ice cream scoop (3 oz.) then flatten the dough. Drape it over the s'mores stack, forming it into a mound over the top of the marshmallow and chocolate, sealing the dough to the graham cracker base. The cookies will spread as they bake so only bake 4-6 at a time on each baking sheet.

Bake at 325 degrees for 7 minutes, then turn the cookies, and bake another 6-8 minutes or until the edges get slightly golden brown (about 13-15 minutes total). The cookies will spread, this is normal. Remove from the oven and use the back of a spoon or measuring cup to scoot up the edges to form the cookies into a round shape. Add a few additional chocolate chips on top along with a sprinkle of finishing salt. Allow to cool and enjoy!
