Poorly party cakes

My little boy has had chicken pox this week, so we've been housebound and entertaining each other with lots of painting, crafts and of course baking.  On Friday some friends were due to come over with their 1 year old in the hopes of infecting him, so I decided we'd make some cakes for the 'poorly party'.  My boy decided he wanted vanilla cakes, and I had some orange buttercream in the freezer that I got out for the occasion.  We covered each cake with a little layer of the buttercream and then coloured some blue and some green for decoration.  We used spotty cake cases, and our plan was to decorate the cakes in spots too however artistic license and 3 year old enthusiasm took over when we were actually icing them - piping bags are FUN!
