Hello,
Hoping to get some help sizing up Nigella's chocolate fudge cake. I'm making it as a birthday cake for a friend, being served after a meal in a restaurant (who are happy for me to provide it).
I can double the recipe (which normally bakes in 2 x 20cm/ 8in tins) and make two 23cm/ 9in square cakes. I think this gives me 30 slices 3.5 x 4cm. That would make them tall and narrow slices, iykwim.
Am I better off just doing a large single layer of sponge in a roasting tin, so everyone gets a slab with one layer of icing?
Any thoughts?
