Where can I get a plain iced birthday cake?

[furrycat]

I'm buying a cake topper on ebay which you attach to a ready-iced cake. But the only plain iced cake I can find is Christmas cake - I need sponge. Any ideas anyone?

Tescos/Sainsburys and Asda do their own photograph cake which is sponge,you can buy it without the photo being put on.

I have also bought a fairly plain one ie. one with some ballons on it,and carefully lifted the balloons off with a knife,if that helps.

m&s usually do these.

can't see it on m&s online, but is usually next to wedding cakes in store

Sainsburys do a nice plain madiria (sp?) birthday cake
