How Long Does Cake Last in the Refrigerator?
Most cake keeps 3 to 5 days in the refrigerator, but cakes with whipped cream, custard, cream cheese, mascarpone, or fresh fruit are best used within 3 to 4 days. Store it covered at 40 degrees F or below, and follow the shelf life of the most perishable filling or topping.
