For some of us, it isn’t dessert if it isn’t chocolate. 1. Pink swirls adorn Burrow’s “Chocolate Cake Bon Bon” of dark-chocolate cake and ganache cream. 2. Layers of flourless chocolate cake, mint cream, and chocolate mousse are dubbed “Young Grasshopper” at Lafayette. 3. Lafayette’s “Hazelnut Rocher” is gianduja (chocolate-hazelnut) mousse with orangecognac cream in a crunchy coating. 4. Eataly’s “Terracotta” is flourless chocolate cake topped with milk-chocolate mousse and filled with butter caramel.
