Hi Turando, its a heavier denser cake usually. The name comes from the "olden days" when you used a pound of butter, a pound of eggs etc etc to make the cake. They fed a lot of people in those days. LOL.

Also, pound cakes are seldom frosted, at least not conventionally. Like ChefJune, I like the cake better than the frosting, so I prefer pound cakes or bundt cakes that might be lightly glazed, but not topped with gooey frosting.
