A quick bread is an American term used to denote a type of bread which is leavened with leavening agents other than yeast. Examples of such agents include baking soda (sodium bicarbonate) plus an acid, such as cream of tartar, lemon juice or cultured buttermilk, to elicit an acid-base reaction that releases carbon dioxide. Baking powder can also be used as it contains an acid and a base and simply needs a liquid medium in which to react. Other leavening agents are egg whites beaten to form stiff peaks as in the case of many waffle recipes, and steam, in the case of cream puffs.
