What is the infringement of Snickers, Bueno…etc?

What is the umbrella term for Snickers, Mars, Milky Way, Maltesers, Galaxy, Bueno, KitKat, Duplo, Bounty, Knoppers, Hanuta, Schoko Bons, Twix, Oreo, M&Ms, etc… I mean, chocolate is way too vague, just like candy… can anyone think of something more precise? If you know a precise, appropriate English term, feel free to write it.
