The new chemical leavening bases comprise a baking bicarbonate, preferably an alkali metal bicarbonate, ammonium bicarbonate, or a mixture thereof, which has been intimately admixed with a food grade, essentially water insoluble salt or oxide, such that the baking carbonate acts as a carrier for the insoluble salt or oxide which is essentially uniformly distributed throughout and in the surface of the bicarbonate. The leavening system can be used in any type of baked goods which is leavened by a leavening system which includes a gas generating base such as a baking carbonate and a neutralizing acid.
