my friend has asked me to make her ds a batman bday cake..

[mumineedapooooo]

first attempt picture is on my profile she doesnt want it for another 2 weeks so i can eat this one all to myself

im quite pleased with it but the sponge inside is three layers and the icing has sagged in between giving ripples on outside,how can i stop this happening?did i roll the icing too thin?

Dont know about the icing but the cake looks fab.

Marzipan. Nice cake btw. :)

Lovely design! Is the cake a Victoria sponge mix? If so it might not be able to take the weight of the icing. If you add an extra 50g of flour on top of what's in the recipe already it'll make a denser sponge like a Madeira cake which will be sturdier. Also, have you got an icing smoother/polisher?
