Pound cake is a type of cake traditionally made with a pound of each of four ingredients: flour, butter, eggs, and sugar. Pound cakes are generally baked in either a loaf pan or a Bundt mold. They are sometimes served either dusted with powdered sugar, lightly glazed, or with a coat of icing. It is believed that the pound cake is of northern European origin and dates back to the early 18th century. A recipe for pound cake appears in The Art of Cookery by Hannah Glasse, published in 1747. The first U.S. cookbook, American Cookery, published in 1796, has a recipe for pound cake. Over time, the ingredients for pound cake changed. Eliza Leslie, who wrote the 1851 edition of Direction for Cookery, used 10 eggs, beat them as lightly as possible, mixed them with a pound of flour, then added the juice of two lemons or three large oranges. This changed the flavor and texture of the cake. In the 2008 issue of Saveur, James Villas wrote that cake flour would not work in place of all-purpose flour because it lacks the strength to support the heavy batter.
