The baking powder is a white powder that is used to leaven breads and other baked goods. It consists of bicarbonate of soda (a base) and cream of tartar (an acid). When mixed with a wet ingredient, such as milk, the baking powder produces carbon dioxide gas, which causes the bread to rise. Baking powder that is past its expiration date will not produce carbon dioxide gas and will not leaven the dough. The baking powder will be a darker color and will have a sour smell.

What Makes Baking Powder Active?

Baking powder is a leavening agent composed of baking soda (sodium bicarbonate), an acid, and cornstarch. When wet, the cornstarch absorbs moisture and creates a thick paste. The baking soda and acid react with each other to create carbon dioxide gas. This gas is trapped in the thickened paste and forms small bubbles. When these bubbles heat up in the oven, they expand and cause the bread to rise.

What Happens If You Use Bad Baking Powder?

Bad baking powder will not produce carbon dioxide gas, which is responsible for leavening in baked goods. This will cause the baked good to be dense and not rise.
