Quick breads generally refer to any baked good not leavened by yeast or eggs. Typical leaveners used in quick breads are chemical leaveners, such as baking powder or baking soda. The quick chemical reaction of these leaveners allows the bread to be baked immediately.
Quick breads are staples in the American diet. Some examples of quick breads include biscuits, muffins, scones, banana bread, soda bread, and even pancakes and waffles. In the morning, you are likely to see a bigger selection of quick breads in the form of scones and muffins. Later in the day and into the evening, you are likely to see a wider variety of breads or cakes instead.
