How Long Does Rhubarb Cake Last at Room Temperature?

Rhubarb cake lasts about 1 to 2 days on the counter if:

It is stored in an airtight container
-
The kitchen temperature is below 70°F (21°C)

If the weather is hot or humid, refrigeration is recommended sooner.

Properly stored, rhubarb cake lasts 4 to 5 days in the fridge.
To store rhubarb cake in the refrigerator:
-
Let the cake cool completely.

Place it inside an airtight container.
Cold storage slows bacterial growth and helps maintain freshness.
