I just baked two batches of the Pumpkin Poundcake featured on this website over the past few weeks. Does anyone have a recipe or an idea for a recipe for a cream cheese glaze for these cakes? Basically, I need something that will hold up at room temperature and not require refrigeration, as I am bringing the poundcakes as a host gift for Thanksgiving, and the reason that I choose the poundcakes was because they wouldn't require heating or cooling, and they wouldn't have to be eaten on Thanksgiving day. To me, these cakes scream, "bathe us in cream cheese icing," but unfortunately I don't trust that a cream cheese icing (basically a buttercream of sorts) could hold up being without refrigeration for hours and more likely days on end. Any and all suggestions would be much appreciated. Thanks in advance!
