Break the candy bars into bits and drop them into a saucepan
. Add the butter and melt
, over lowish heat, stirring frequently with a rubber spatula
. When everything is melted (the nougat-like layer takes the longest to go), tip in the cereal
and turn them, with your rubber spatula, in the chocolate
mixture until they are all pretty well coated.
Fill the mini muffin papers with the mixture and put in the refrigerator, on a small sheet pan
or tray, for at least 1 hour.
