I was stationed in Scotland in the Navy in 1976. I stepped off the plane and wandered through the airport at Prestwick and ended up at a candy place which is not hard to do in Scotland. This was my first bite to eat in Scotland and I still love them today. The Mars bar in Scotland is most like a Milky way but you could use a Three Musketeers or a Snickers. Oh my good gravy, if ya love your young uns you HAVE to make them these (so you have an excuse to eat them).
Cut candy bars in little chunks and place them and butter in pan and melt over low heat. Then pour this over the cereal and stir well. Drop by spoonfuls into mini muffin papers and let cool. Makes about 40.
