I have a bowl of leftover buttercream (about 4 cups, made with butter and shortening) Is is possible at this point to add some cream cheese to it to make a cream cheese frostig? I'd also like to ad a little cinnamon.
I want to use it to frost spice cupcakes . I don't want to ruin it becauase I am taking them to a pot luck dinner today. Thanks for any help ![]()
