Alice's chocolate birthday cake

///////////////////////////
150g butter
8 medium eggs
salt
400g chocolate (dark)
caster sugar
tub of creme fraiche
zest of 1 lemon
///////////////////////////

Heat the oven to 180C/Gas Mark 4 and use a little butter to grease two 15" round cake tins. Separate the eggs into two bowls. Whisk the yolks with a pinch of salt and set aside.

Meanwhile melt all the chocolate and butter in a heatproof bowl placed over a pan of simmering water. Do not allow to get too hot. Once melted allow to cool off for 5 mins or so and mix in the egg yolks.

In a separate bowl whisk the egg whites until stiff peaks, then whisk in approx 3 tablespoons of caster sugar. Using a metal spoon fold in the chocolate mixture.

Bake for 15 mins and cool thoroughly before sandwiching together with the creme fraiche and lemon zest mixture. I cut a heart out of paper and dusted icing sugar around it to finish off Alice's cake, but you can cut whatever shape you like :)
