What is the healthiest cake?

A cake is healthy as long as it does not contain pigment, essence and gelatin, and it uses animal oil, but it is difficult for ordinary cakes to do so. For example, pigment and essence ensure the color and fragrance of cakes, gelatin ensures the long-term preservation of cakes, and most cakes use hydrogenated vegetable oil to save costs. . At present, the healthier cake is brocade cake.
