it can stay fresh for 2 weeks
A cake without frosting can typically stay fresh for about 2 to 3 days at room temperature if stored properly in an airtight container. When frosted, a cake can last up to 5 to 7 days, as the frosting helps to seal in moisture and protect the cake from drying out. Refrigeration can extend the freshness of both types, but may also alter the texture. Always check for signs of spoilage, regardless of the storage method.
It will stay fresh for some hours. Not too long. So it depends how long the fridge been off. Too long is bad.

When choosing a shelf-stable frosting for long-term storage, look for options that are specifically labeled as shelf-stable and have a long expiration date. Consider factors like the ingredients used, the packaging, and any preservatives added. Opt for frostings that are sealed tightly and stored in a cool, dry place to ensure they stay fresh for an extended period of time.

A frosted cake will stay fresh overnight without being stored in a container. In fact, the fat and moisture from the frosting will improve the cake.
