Hey, they sound great!
I made some after dinner mint ice-cream buttons last weekend. Just made up a batch of low-carb mint ice-cream (double cream, milk, splenda, peppermint extract) in the ice-cream maker and froze it in a silicon chocolate mould (from Lakeland) - when frozen hard take each of the ice-cream buttons and dip it in melted dark chocolate - put it on waxed paper on a baking tray and pop it back in the freezer. When solid, put in an air-tight tub and store in the freezer. Take out 10 minutes before you want to use.
