How long does unrefrigerated rum cakes last?

Rum cakes, when properly made and stored, can last for several weeks at room temperature. The high concentration of sugar and alcohol in rum acts as a preservative, inhibiting the growth of bacteria and molds. However, it's important to consider the following factors to ensure the longevity and quality of your rum cakes:

1. Baking Process: Make sure the rum cake is thoroughly baked before removing it from the oven. An undercooked cake will spoil more quickly.

2. Cooling: Allow the rum cake to cool completely before storing. This helps prevent condensation from forming inside the container, which can lead to spoilage.

3. Sealing: Store the cake in an airtight container or wrap it tightly with plastic wrap to prevent it from drying out and absorbing moisture from the surroundings.

4. Storage Location: Keep the rum cake in a cool, dry place away from direct sunlight. Avoid areas with high humidity, such as the refrigerator or near the stove, as moisture can promote mold growth.

5. Duration: Generally speaking, rum cakes can last for up to 3-4 weeks at room temperature under ideal storage conditions. However, it's always a good idea to check the cake regularly for any signs of spoilage or mold growth.

6. Ingredients Quality: The quality of ingredients used in the cake, including the rum, can affect the shelf life. High-quality ingredients generally lead to a longer-lasting cake.

7. Consumption: If you're not planning on consuming the cake within the recommended time frame, it's best to store it in the refrigerator or freezer to extend its shelf life further.

Remember, these guidelines are general recommendations, and the actual shelf life of a rum cake may vary depending on the specific recipe and storage conditions. If you have any doubts about the freshness of your rum cake, it's best to discard it for safety reasons.
