Baking powder is a leavening agent commonly used in baking to help dough and batter rise. It typically consists of a combination of an acid (like cream of tartar), a base (like baking soda), and a moisture absorber (like cornstarch). When mixed with wet ingredients, it produces carbon dioxide gas, which creates bubbles that cause the mixture to expand and become light and fluffy.

Baking powder is used in small amounts (usually 1–2 teaspoons per recipe) and even a slight excess can make baked goods taste bitter or collapse after rising. Measuring by weight is the most reliable way to get it right. Use the converter below for grams, cups, teaspoons, and more.

Baking soda (bicarb) is the pure alkali inside baking powder, with no built-in acid, so it is roughly three times stronger. They are not a 1:1 swap: to replace baking powder with baking soda you need to add an acid such as cream of tartar, and use about a third of the amount. See our Baking Soda (Bicarb) converter.

Cream of tartar is the dry acid inside baking powder. Use the cream of tartar converter for teaspoon and gram conversions when pairing it with baking soda. See our Cream of Tartar converter.
