OK, I'll bite...once or twice...
I love Schoolbread, but Ill take it as a snack to be greedy and say my favorite dessert is from Mama Melrose:
Happiest Celebration on Earth Coffee Tartufo : House-made coffee ice cream crusted with crushed coffee beans, chocolate, butterfingers, and hazelnuts with a sambuca Anglaise sauce
Drooling right now just thinking of it.
