I don't know in English, but the original name is Gianduia. Chocolate flavor made in Italy and takes its name from a famous carnival mask. In Italy you can find chocolate candies with that flavor and their name is Gianduiotti. They are hazelnut based.

And about the maroon (still not sure if that's English name) they are a kind of chestnut. They are a bit bigger and darker than chestnuts with a slightly different shape. They are used to make a kind of candy (I guess French) called Marron Glasse'.
