Joconde Sponge Adapted from Joe Pastry’s joconde sponge recipe. This recipe makes a batch of cake that’ll fit in a 12x18 inch (30x45cm) sheet pan.

Recipe: Proof Bakery’s chocolate espresso layer cake. There is a certain irony operating here. Ma, a Glendale native who opened Proof Bakery in 2010, is not really a cake person.
