Relevance. Rating Newest Oldest. Best Answer: Most traditional carrot cakes do not need to be refrigerated and will typically last for a week. However, if a large part of the cake or its frosting is dairy (like a whipped cream cheese topping or filling) you may want to refrigerate as a precaution. As far as spoiling, keep an eye out for mold (blue, green or black hairy-looking spots) and don't keep it around for longer than 7 days.
I would put a cake with homemade cream cheese frosting in the fridge but the carrot cake with canned frosting should be fine on the counter overnight, if not longer. Homemade cake with homemade butter or cream cheese frosting I would leave out for a few hours but refrigerate if it were being held longer.
