Spray a round pizza pan with cooking spray.
Spread the softened tube of cookie dough over the pan, leaving about ½ inch from the edge.
Bake on 350 for about 7 minutes or until light brown. At this point the cookie won’t be cooked thoroughly, but won’t be gooey in the middle either.
Remove from oven and evenly sprinkle graham crackers over the baked cookie.
Sprinkle the mini marshmallows over the graham crackers.
Sprinkle the chocolate chips over the mini marshmallows.
Bake on 350 for about 7 minutes or until marshmallows are just turning brown on top.
Drizzle chocolate syrup over the marshmallows. Try not to eat it all in one sitting!
