Abstract: A method of coating a wide variety of foodstuffs with tasty marshmallow material simply by enclosing foodstuffs with marshmallows in the same container that permits gaseous venting, but otherwise secures the enclosed foodstuffs. Microwaving the container for one minute or less causes the marshmallow, responding to the microwaves, to radically expand many times its original size. The expanding marshmallow quickly and conveniently coats the secured foodstuffs in the container with a layer of marshmallow material to produce a tasty food treat. The addition of a stick or other handling means is highly desirable, as is a means of easily extracting the food treat from the enclosure and aids in keeping hands clean while eating the food treat.
