Final answer:
Unshortened cakes such as sponge cakes, angel food cakes, and chiffon cakes lack fats like shortening, butter, or oil, instead using eggs for volume and texture.
Step-by-step explanation:
Examples of unshortened cakes include traditional sponge cakes, angel food cakes, and chiffon cakes. Unshortened cakes are characterized by their lack of shortening, butter, or oil, which are typically absent in their recipes. Instead, these cakes often rely on whipped eggs or egg whites to provide their volume and tender crumb. One classic example is the pound cake, which traditionally uses a pound each of sugar and eggs, creating a simple yet delicious cake without the need for added shortening.
