French Queen Marie Antoinette is famous for saying "let them eat cake." She was referring to the leftover scraps of baked products that were collected at the end of the day and divvied up between beggars and peasants who had no bread to eat.
Today, when we choose to eat cake, we have a host of options. The flavor that always rises to the top, however, is the basic chocolate cake. It is customarily moist and tender with a rich, velvety center.
With a multitude of formulas, you can offer many varieties of this classic cake. This chocolate spice cake represents a resurgence of cake made with chocolate sponge, chocolate ganache and an orange gelée. It offers customers that "something chocolate" their taste buds are craving. In this version, the cake is soaked with a caramel spice syrup, ideal for winter, but the syrup can be altered to fit any time of year.
Chocolate cake is always a crowd pleaser at birthday parties, weddings, sporting events and even Sunday dinners. This cake is easily prepared and has a long shelf life, making it an excellent addition to your bakery. Sell the cake whole to serve 10 to 12 people, or slice it into single portions.
