Preheat the oven to 350°F. Line a baking sheet with parchment paper or spray lightly with pan spray.
Arrange 6 graham cracker squares on the baking sheet, leaving plenty of space between each cookie.
Place 2 rectangles of Hershey's chocolate on top of each graham cracker square.
Place 1 large marshmallow on top of each piece of chocolate.
Cut off a portion of refrigerated chocolate chip cookie dough and roll or flatten it into a thin circle large enough to cover one entire s’more.
Place the flattened cookie dough over the graham cracker, chocolate and marshmallow stack. Bring the dough down around the sides and use your fingers to seal it around the graham cracker, forming a small mound or mountain.
Use your finger to make a small rip or opening in the cookie dough directly over the top of the marshmallow. This gives the marshmallow a place to expand through the dough while baking.
Repeat with the remaining cookies.
Bake at 350°F for 12–14 minutes, until the chocolate chip cookie dough is baked and the marshmallow has pushed through the opening in the top.
Remove the baking sheet from the oven and allow the cookies to cool slightly.
While the exposed marshmallow is still warm and soft, press 2 candy eyeballs gently into each marshmallow to create the ghost face.
Allow the cookies to cool completely before serving.
