This is just like making regular S'mores (graham cracker, chocolate squares, marshmallows and another graham cracker) but you use holiday Peeps (snowmen, in this case) for the marshmallows and just microwave for about 10 seconds.
Have you ever watched Peeps in the microwave? They puff up wonderfully. The boys love to watch them.
The ingredients in a small gift bag (my kids recieved these as take-home bags at a dance) would also make a nice addition to a food gift basket.
