Help!! I need to make DD's birthday cake - have followed my usual sponge recipe but the bloody things just won't cook! I now have one stodgy in the middle cake and two slightly burnt! I am (honestly) usually quite good at cakes - the only new thing today is the tin. Is it possible that the tin is too heavy? I bought it to make my Christmas cake and now have a vague recollection of that taking longer than expected to cook.
Don't want to make another in the same tin and have the same problem - if people think it's the tin then I can go and buy a new one, if it's not the tin then I'm buggered!!
