Whole Foods Market’s Berry Chantilly Cake has developed a strong following, with customers serving it at birthdays and weddings and some saying they buy it weekly. The cake’s popularity matters because it has become a recognisable grocery-store dessert with fans describing it as living up to its considerable hype.

The cake consists of vanilla sponge layers, Chantilly cream frosting and fresh berries, according to Whole Foods. The retailer says demand can be so strong that customers have queued for it during power cuts and ahead of natural disasters, underlining its cult status.
