First off, you will need to preheat the oven to 300 degrees Fahrenheit and line a cookie sheet with aluminum foil, shiny side up. For each S’more, break a graham cracker in half, placing one half on the lined cookie sheet. Place one soft, large marshmallow in the center of the graham cracker half. Make sure to have ready the other graham cracker half and a piece of milk chocolate bar, I ALWAYS use Hershey’s milk or dark chocolate, 3 rectangles per S’more. You want a piece of chocolate large enough to cover half the graham cracker.
After you have all the graham crackers with marshmallows lined up on the cookie sheet, bake them in the oven for 4 minutes. Make sure to leave room between the s’mores, as the marshmallows will swell up slightly in the oven and you will end up with an ooey-gooey mess! Carefully remove from oven and immediately place the chocolate bar on top of the marshmallow; press down to spread the warm marshmallow to the edges of the graham cracker and to imbed the chocolate into the marshmallow. Top with the other graham cracker half. Leave of the still-warm cookie
