I have about 1.5 cups of cream cheese frosting left over from making carrot cake cupcakes. It's been sitting in the fridge for a week now. Do you think it's still okay, and is there anything I can bake it into? I would rather not use it to frost anything else, or use it as sandwich filling. I guess I could freeze it. But ideally I'd like to use it as danish filling or turn it into a cheesecake or something similar. Any ideas?
