I'm going to have to pay more attention to the packages.

There is a strict definition on what the word Chocolate means, So much coco so much coco butter, yada yada. It meant a level of quality had to be maintained in order to label it chocolate. So they do an end run by putting "chocolate candy" in the ingredients.

I do seem to recall reading an article where the candy companies wanted to replace the coco butter with alternatives, but were rebuffed by them that control the definitions, don't remember if that was the FDA or Congress.
