A Whole Foods cake was once comparable to one from your local bakery. Fluffy, fresh layers of sponge were the hallmark of the store's bakery department, making the cakes reliable in a pinch for any birthday. According to posters who say they are employees of Whole Foods, the change came when Amazon bought the high-end grocery store in 2017. According to another Reddit poster who claims to be on the bakery team, the layers show up at the store frozen. This may be why it takes 48 hours for the store to make you a custom cake.
