I always have some un-iced vanilla cup cakes in the freezer for emergencies.  Store in an air tight container. When you get a call announcing visitors just whip a couple of cakes out of the freezer and whip up some cream. 
These look extra special when you use coloured cup cake cases and a paper doilee.
Your guests will feel loved and they will be very impressed.
OR you can just do it for yourself.  ENJOY!
