The shelf life of a fresh cream cake out of the fridge can vary depending on several factors, including the ingredients used, the ambient temperature, and the overall hygiene and handling during preparation. Generally, fresh cream is a perishable ingredient, and leaving a cream cake at room temperature for an extended period is not recommended.
In most cases, a fresh cream cake should not be left out of the fridge for more than 2 hours. Bacteria can multiply rapidly at room temperature, potentially leading to foodborne illnesses if the cake is consumed after being left out for too long.
To ensure the freshness and safety of the cake, it's best to store it in the refrigerator when not being served. If you're planning to have the cake outside for a while, consider keeping it in a cooler with ice packs to maintain a safe temperature.
Always use your best judgment and practice food safety measures when dealing with perishable items like fresh cream cakes. If you're unsure about the cake's safety, it's better to err on the side of caution and discard it.
