Fudgy Double Chocolate Cake for Birthday

Luke didn't get chocolate cup cakes to bring to school, so I promised him a very chocolate birthday cake.  He's into simple things, so, a fudgy chocolate cake he chose from the library book Epicure Chocolate. 

Fudgy Double Chocolate Cake

120g butter
250g Lindt's dark chocolate 50% cocoa
2 cups self raising flour
2 eggs
1.5 cup sugar (I used 1 cup white sugar, 0.5 cup brown sugar)
3/4 cup milk
1/2 cup warm water
1/2 cup cocoa powder

Preheat oven to 180C.
Beat egg with sugar until ribbony and at the meantime, melt chocolate and butter. 
Mix the liquids once chocolate and butter cool a little, and add water and milk last.
Sift flour and cocoa powder together into a clean bowl,  and then add to the liquid.
Fold and mix well.  Line and grease a 20cm spring form tin (it's higher than normal cake tin) and bake the cake for 45 minutes. 
The cake might still be a bit gooey in the middle, that's fine.  Cool and then chill in fridge before apply icing.

100g Lindt's dark chocolate 50% cocoa

100ml thickened cream
30g butter

Luke didn't like other icing, but I had to explain to him that with out another colour, I can't write on the cake... the yellow icing was the bit of left overs from his cup cakes...
