Hi all, having a surprise party for DP on the 8th of October and want to do as much as possible in advance. I've got Dr Oetker ready to roll icing to cut out little 30s to put on cupcakes, didn't get fondant icing as I'm not making 3D things so thought it wouldn't matter, does anybody know if I can make these soon-ish and store in a Tupperware until the party?
