Baking powder is a leavening agent commonly used in baking to help baked goods rise. It typically contains a combination of an acid (such as cream of tartar) and a base (usually baking soda), along with a moisture-absorbing agent like cornstarch. When mixed with liquid and exposed to heat, baking powder releases carbon dioxide gas, causing the dough or batter to expand and become light and fluffy.
