Pound cake got its name because the original recipe used exactly one pound each of butter, sugar, eggs, and flour.

The first written recipe for pound cake appeared in 1796 in a book called American Cookery by Amelia Simmons. Back then, bakers did not have baking powder or baking soda to make cakes fluffy. Instead, they had to whip the butter and eggs by hand for a long time to trap tiny air bubbles inside the batter. This is called creaming, and those little bubbles expand in the heat of the oven to help the cake rise.The original recipe created a massive cake that weighed four pounds and packed over 8,000 calories. This was actually helpful in the 1700s because people did a lot of hard physical labor and needed the energy. One pound of butter alone has about 3,200 calories, while a pound of sugar adds another 1,700 calories. This high fat and sugar content also helped the cake stay fresh for a long time without a refrigerator.In France, this same style of treat is called quatre-quarts, which means four-quarters. This name refers to the four equal parts of the ingredients used to bake it. While modern bakers often add extra ingredients to make the cake lighter, many people still love the thick, rich texture of the classic version.
