Heat outdoor grill or inside oven to 400 degrees Fahrenheit.

Line a sheet pan with aluminum foil.

Lay 15 graham crackers end to end in 3 rows of 5 along the bottom of the prepared sheet pan.

Layer one chocolate bar on top of each whole graham cracker, Add a generous layer of marshmallows, about half the bag, being sure to spread them out evenly over the chocolate. Top with the remaining crackers.

Place the sheet pan in the hot grill with the lid closed or oven and grill/bake for about 10-15 minutes or until everything is nicely melted and warmed through.Be sure to set a timer at the shortest time to ensure the s’mores don’t burn.

Serve warm with lots of napkins!
