If you are using the original recipe for cream cheese icing to fill this cake, it must be kept refrigerated, but I find it is best served room temperature so set it out for about 1 hour before serving.
If you a re using the 2-2-2 Cream Cheese Icing recipe then it can stay at room temperature for up to 3 days
Store for up to 1 week in the refrigerator covered for freshness
Cake can be frozen for up to 1 month wrapped well to prevent drying
