A toddler girl's dream come true! After looking all over the place for instructions, I finally put a few different construction ideas together. I bought a cheap barbie, undressed her, wrapped her legs in cling film and used her in the cake. After the cake had been cut, I unwrapped her from the cling film and dressed her and gave her to my daughter, who still talks about her doll's 'beautiful cake dress'! I used a 2-litre/4-pint oven-proof mixing/pudding Pyrex bowl and a 20cm round cake tin. Barbie's legs are long, hence the extra 20cm cake under the bowl-shaped one. Prep time includes decorating time.
