When I first read the question I too was thinking about sweet tobacco which I'm sure was called "Gold something" (can't remember the second word) but this wasn't bought loose. But the more I think about it there was something more like you're describing... I think there were two types, one was like toffe blob shaped things coated in chocolate, and the other was similar but had a sugary covered coating but I just can't think what they were called. Hopefully this will help to kog other peoples' memories.
