Bakers Dozen East and West—a group of dedicated bakers on both coasts—meet in this recipe. This is a special tribute to Flo Braker, long-time friend and much-respected colleague, and one of the founding members of Bakers Dozen West. I thought it would be fun to combine Flo’s best chocolate cake, the Dark Chocolate Cake, with mine, the Chocolate Domingo. Flo’s cake is more bittersweet, less dense, and moister, while the Domingo is more mellow and compact. The combination of the two turned out to be a very happy marriage, resulting in a bittersweet chocolate cake that is buttery, mellow, airy, and moist. The white chocolate caramel buttercream is a perfect foil for the bittersweet chocolate. For extra drama I like to add the optional lacquer glaze.
