[Lucycat]

I am in utter lust with this cake, it's fab and the cola does the same thing to the cake as it does to Nigella's gammon - turns it into something wondrous......

Thank you!

I thought the dc's would like this. However have just prepared the mixture and it looks awfully runny! Is that right? I thought maybe there should be some extra flour.

Anyway, I'll wait and see how it turns out.

It's a bit flat! I reckon something not quite right here!

can anyone tell me what temperature GM4 is, please?

yes it does stay quite flat but that's because it's lovely and moist in the middle, if you want it to be more of a sponge cake then yes you will need more flour.

It has quite a solid centre - a least mine does

oh sorry 180c or 350f

Do you use regular or diet coke? Or doesn't it matter?

I use regular - I had some left after doing nigella's gammin - but supermarket own brand should be ok.

Made this cake this afternoon, Lucycat.
It was well recieved by everyone - there is none left!
I lined my tin with greaseproof rather than foil. It was fine.
Thanks.
