Angel food cake differs from other cakes in that it does not contain any type of fat, such as butter or oil. This results in a lighter, fluffier texture and a cake that is lower in calories and cholesterol. Angel food cake is made primarily from egg whites, sugar, and flour, creating a delicate and airy cake that is perfect for pairing with fresh fruit and whipped cream. It is also gluten-free, making it a great choice for those with gluten sensitivities.
