Butter cakes are a type of cake that is rich and moist, made primarily with butter, sugar, eggs, and flour. The butter is creamed with sugar to create a light and fluffy texture, which helps the cake rise during baking. This method results in a tender crumb and a deliciously buttery flavor. Common variations of butter cakes include pound cake, yellow cake, and chocolate cake. They can be enjoyed plain or frosted with various types of icing, such as buttercream or cream cheese frosting. Butter cakes are popular for celebrations and can be easily customized with fruits, nuts, or chocolate chips.
