Dr Who's Tardis riding the vortex! This is a chocolate sponge covered in ganache and sugarpaste. Hand painted swirl pattern to represent the vortex swirly pattern thing...yup, that'll do! Original Tardis was also sponge and was too heavy and actually split my base cake, but after fixing and not being happy with it I decided last minute (after forgetting the idea completely existed) I made the tardis out of RKT. Was for a little boy who turned 5. Wasn't quite as perfect as I'd have liked, but it worked - made him happy!!
