Can a cream cheese cake be left out and for how long?
If you have a true pound cake, it should be good at room temperature for 2-3 days, well wrapped.



The title of your question made it sound like you have a cheese cake, perhaps with a pound cake base.  If that is the case:

Cheesecake is essentially a custard of cream cheese, eggs, and dairy.

None of these foods should normally be left at room temperature for an extended period of time, as they are all quite perishable.

I would recommend leaving a cheesecake out for no more than 2 hours or so, the same as any other perishable food.
