Baking powder is a chemical leavening agent composed of a base (typically sodium bicarbonate), one or more acids (such as cream of tartar or sodium aluminum sulfate), and a moisture absorber (usually cornstarch or potato starch). The mixture is designed to release carbon dioxide gas when moistened and heated, causing batters and doughs to rise during baking.

Modern baking powder is predominantly "double-acting," meaning it releases gas in two stages: first when mixed with wet ingredients at room temperature, and again when exposed to heat in the oven. This dual-release mechanism provides more reliable and controlled rising in baked goods. Single-acting baking powder, which releases gas only upon heating, is less common in contemporary use.

Baking powder is essential in quick breads, cakes, cookies, pancakes, biscuits, and muffins where rapid rising without fermentation is desired. It is commonly used in conjunction with or as a substitute for yeast in recipes requiring immediate baking. The ingredient is particularly valued in American, British, and Northern European baking traditions. Proper measurement is critical; too much baking powder produces a bitter, metallic taste and coarse crumb, while too little results in dense, flat products. It is typically combined with dry ingredients before wet ingredients are incorporated.
