Does this icing need to be refrigerated? Or can it be left out?

I'm doing a Italian Cream Cake with the crusting cream cheese icing for tomorrow.. my house is very cool, but I want to make sure it doesn't have to be refrigerated.

Does anyone know?

Thanks!

I would recommend refrigeration for that just in case factor.

I always put mine in the fridge....I just don't like to take a chance!

Thanks!! I'll put it in the fridge!

Cheryl do put it in the icebox!! I've used that recipe before & it definetly needs to go in the icebox. Any cream cheese icing does. It just melts quick where we live~
