Does cake spoil when not kept in a refrigerator?

Cakes, especially those containing perishable ingredients such as dairy, eggs, or fresh fruits, can spoil if left unrefrigerated for extended periods. The shelf life of a cake depends on several factors, including the type of cake, its ingredients, and the storage conditions.

Here's a general guideline on how long cakes can last at room temperature and when refrigeration is necessary:

1. Plain Cakes (No Perishable Ingredients):

- Room Temperature: 2-3 days

- Refrigeration: Not necessary unless the cake stays at room temperature for longer.

2. Cakes with Frosting (Buttercream, Cream Cheese):

- Room Temperature: 1-2 days

- Refrigeration: Recommended to prevent spoilage of dairy-based frosting.

3. Cakes with Fresh Fruits or Toppings:

- Room Temperature: Same day or overnight

- Refrigeration: Necessary to maintain freshness and prevent rapid spoilage.

4. Chocolate Cakes:

- Room Temperature: 3-4 days

- Refrigeration: Optional, but refrigeration can help maintain the cake's texture.

5. Store-Bought Cakes with Preservatives:

- Room Temperature: As per the "best before" or "expiration" date on the packaging.

It's always a good practice to follow the storage instructions provided by the baker or manufacturer to ensure the best quality and safety of your cake. If you're unsure whether a cake can be left unrefrigerated, it's best to err on the side of caution and refrigerate it.
