Ok ladies thanks for all the advice, I have just had a busy weekend of baking and now have 2 marble butter cakes and a set of cupcakes in the freezer (for dd kindy on wed). My transfer has now been moved to thursday. My plan at the moment is to take the cupcakes out and make two lots of butter cream on tuesday night. I can then decorate the cupcakes on wednesday morning before she goes to kindy. Should I then freeze the second lot of butter cream and take both the butter cakes and buttercream out on wednesday night before I decorate the cake Thursday morning before transfer at lunch time? Will the cake be ok until Saturday that way? That gives me all of Friday to chill out before party.
