How is "quick bread" characterized?

Quick bread is characterized as a type of bread that is leavened with baking soda or baking powder rather than yeast. This method of leavening allows for a quicker preparation and baking process, as it eliminates the need for fermentation and long rising times associated with yeast-leavened breads. The use of chemical leavening agents enables the bread to rise rapidly as it bakes, providing a light and fluffy texture typical of quick breads. Examples include banana bread, muffins, and pancakes. The focus is on the immediacy of preparation, which distinguishes quick breads from traditional yeast breads that require proofing and longer preparation times.
