Coffee Cake

Coffee cake is cake intended to be eaten with, or flavored with coffee.

Coffee cakes, as an accompaniment for coffee, are often single layer, flavored with either fruit or cinnamon, and leavened with either baking soda (or baking powder), which results in a more cake-like texture, or yeast, which results in a more bread-like texture.

Sour cream is used in traditional coffee cakes to both impart a tart flavor and activate baking soda used as a leavening agent.
