Chocolate cake is a dessert popularized at the end of the 19th Century and popular internationally. The cake is often served at gatherings such as birthday parties and weddings.
Ingredients vary depending on the recipe but usually include a combination of eggs, sugar, cocoa powder, chocolate, butter or oil, salt, and baking soda. Water or milk is also used. Other additions and variations may include melted chocolate, sour cream, buttermilk, fruit juices, or syrups. Bakers use vanilla extracts, liqueurs, or flavored liquids like coffee to bring out different properties in the chocolate flavor. A variety of toppings, icings and glazes can also be used, as well as spices.
Traditional approaches to chocolate cake are still popular and chocolate cake is also a basis for other cake varieties such as Black Forest cake and German Chocolate Cake, which includes coconut, pecans, caramelized cream, and chocolate cake.
