Fiasconaro (of Sicily) make panettone with Candied Chestnuts and Gianduja for Dolce & Gabbana. If you live in the EU and want to see the whole range, go here. If you live in the US, Neiman Marcus does not have this particular one, but they have some other Fiasconaro + Dolce & Gabbana panettone, including one with citrus and saffron for $65. (And I did not do an exhaustive search, other stores might have these.)
