Baking powder is a chemical leavening agent consisting of sodium bicarbonate, an acid (typically cream of tartar or sodium pyrophosphate), and a starch filler. It provides no meaningful macronutrients but contributes significant sodium; a teaspoon (~4g) contains around 400–500mg sodium. It is used in very small quantities to aerate baked goods and should not be confused with plain flour or bicarbonate of soda.
Use the quantity specified in the recipe — too much baking powder produces a bitter, soapy taste and can cause baked goods to collapse. Check the expiry date; old baking powder loses its potency and results in flat bakes.
