Today, February 23, 2014, is National Banana Bread Day. . Banana bread is a type of bread that is made with mashed fully ripe bananas. It is often a moist, sweet, cake-like quick bread; however, there are some banana bread recipes that are traditional-style yeast breads. Banana bread first became a standard feature of American cookbooks with the popularization of baking soda and baking powder in the 1930s.
