Has anyone made this, and if so was it successful?
I want to make it for DS1's birthday cake on Friday, but I'm a little bit anxious as the recipe (which is in 'Feast', if you're looking) only wants 15g of butter in the cake.
This strikes me as incredibly little, is this really true or a typo?
I have about 12 years of trusting Nigella, but after the Guinness gingerbread debacle at Christmas, I'm not prepared to take the risk 
All advice gratefully received.
