Hands off this cake until the day after you have made it!
Honestly, it will taste far better on the following day when the flavours have had the time to develop and the cake will soften up a bit.
Don't you love the fabulous yellow colour of the cake. It's made with Italian eggs. I made it in Italy and the eggs there are a wonderful yellow. Nigella always uses them but I have no idea how to get them in the Uk. More's the pity as would love to have that colour on my cakes here.
Tis cake is a simple creamed sponge cake, but what makes ir different is the addition of melted chocolate to one half of the mix and the amaretti soaked biscuits distributed throughout the mixture.
