I'm making a birthday cake for ds 3rd birthday. Needs to be quite big cos we have loads of kids and adults coming to party.
I am planning on using a large roasting tin that I have which is 25cm x 35cm and I am going to bake 2 cakes and sandwich together. (Then decorate as Toy Story)
Trouble is I cannot find any recipes or sites which tell me the appropriate quantities for a size of tin like that. (But I have found advice saying I shouldn't just double up my sponge recipe!)
Please can you help!
Thanks
