S'mores are made with graham crackers (not cookies), chocolate, and marshmallows. The traditional way to make s'mores is by roasting a marshmallow over an open flame until it turns golden brown and gooey. Then, the toasted marshmallow is placed on a piece of graham cracker, topped with a piece of chocolate, and covered with another graham cracker to form a sandwich. The heat from the marshmallow melts the chocolate, creating a delicious and iconic treat.
