A Candy bar is a handy snack food usually covered in chocolate if the manufacturer knows what's good for them.
For it does not matter what is inside; nougat, nuts, more chocolate, #3 pea gravel. Most people may take one bite at most and down the rest of a candy bar, perhaps not bothering to take off the wrapper. In fact, many people today buy boxes of 12 or 24 candy bars, cut a hole in the end, then pour candy bars down their throats. There are candy bars advertised as being minis or "bite-sized", but those are for wimps.
