It was my first try with fondant icing and wasn't too hard, although I only bought one packet so had to roll it really thin to make it last the distance which made it a bit more difficult (and hence the little roses covering up the not so pretty bits - I would have done more but there was literally no icing left)
I made 2 chocolate cakes from an Annabel Langbein recipe - all made in the food processor and is for 2 cakes which I iced together with buttercream icing to get the height. ( actually there were 3 layers to cover the dolls legs - I cut around the edges and used the xs to piece together the top layer)
Next time I will use more icing and roll it thicker, plus trimming the edges would make it a bit neater but everyone, especially the birthday girl was impressed (especially as she gets to keep the doll , I'd resisted buying her one until now - which no doubt makes them more desirable).
I got the idea from a Donna Hay magazine -which had pretty good step by step instuctions.
