I can't believe I forgot to post this!
I went to a Mets game last week (and they won!), and for the first time since Citi Field opened, had dessert after my Nathan's hotdog and fries. I got a cup of chocolate Carvel and was pleasantly surprised by how dark and chocolaty it was. Turns out, rather than the usual bland chocolate custard, it was chocolate fudge. It had an almost gelato-like texture and a true chocolate flavor. Sorry for the poor focus on the cup, but doing closeups on a digital phonecam with one hand isn't easy. ;)
