We were needing a little dose of summer and these did the trick!
Line a baking sheet with foil and lay out graham crackers squares. Place 6-10 chocolate chips on each cracker and top with a marshmallow. Set oven to broil and place baking sheet on top rack. Watch carefully and remove once marshmallows are golden brown on top. (If you are compulsive like me, you can flip them over at this point and brown both sides of the marshmallow, but it is not necessary!) Top with another cracker square and allow to cool briefly before eating.
