Isobel was 7 but Big Hero 6 ... I couldn't resist in putting a number 6 on the cake (I did send it out with a 7 as you can see from photos).
The cake is an 8" chocolate fudge and I loved every minute of making it. Not as easy as I had thought though, but ... you live and learn (not to be so cocky!).
Thoroughly enjoyed airbrushing those buildings and .. . yup, great cake to make.
