Superfatted → It is formed from "super-" (meaning above or over) and "fatted" (from the verb "fatten", meaning to make fat). The word "superfatted" refers to something that has been made excessively fat or has an excess of fat.
Think of something that is made 'over' ('super-') fat — that's why 'superfatted' means excessively fat.
