I was asked to make a fire engine cake for a boy who loves Fireman Sam, so as I have the Debbie Brown book with instructions for just that, this is what I made. I think the adults got more of a kick out of it than he did - they're not used to seeing novelty cakes like this!

It is 10" x 5" and 5" high, vanilla sponge cake, filled with alternate layers of IMBC and raspberrry jam (with the seeds removed!).
