While chocolate and fudge are both a kind of confection or candy, chocolate is an ingredient to flavor fudge and not all fudge is chocolate flavored. The main ingredients for fudge are sugar, butter, and milk, and from there it can be flavored with chocolate, or a variety of other flavors like maple, peppermint, peanut butter, vanilla, etc. Chocolate on the other hand is made with cocoa beans, cocoa butter, sugar, and sometimes milk.
