Baking powder: measure by the teaspoon
Baking powder is used in small amounts, so the teaspoon matters more than the cup — a teaspoon weighs about 4.6 g. A typical rule of thumb is 1 to 1¼ teaspoons per cup of flour for a standard rise. Most supermarket baking powder is double-acting, releasing gas both when mixed and again in the oven.
It loses strength over time; to test, stir a teaspoon into hot water and look for an immediate fizz.
