Sour Cream Frosting-Will it keep at rm temp?
This is a follow up to a making chocolate cake in advance. The frosting I am using is a chocolate frosting w/ sour cream...will this keep at rm temp? I've already made it and need to know if I need to store it in the fridge. If I do I assume I need to bring it back to rm temp for frosting, is that correct?
Thank you in advance.
