How Long Does Carrot Cake Last at Room Temperature?
Carrot cake lasts about 1–2 days at room temperature, only if it does not have cream cheese frosting.
If your carrot cake is unfrosted or lightly glazed, it can safely sit out for:
-
Up to 24 hours in warm or humid environments

Up to 48 hours in a cool, dry room
However, carrot cake is a high-moisture cake, which means it spoils faster than dry cakes like pound cake or sponge cake.

Carrot cake with cream cheese frosting should NOT sit out for more than 2 hours.
