This is rich, delicious and my favourite brownie. Easy to make too.
Melt together 200g (7 oz) of 70% dark chocolate, 650g (23 oz) of butter and 50g of cocoa powder until smooth and glossy. In another bowl whip 2 large or 3 small eggs with 150g (5½ oz) of caster sugar. Add this to the chocolate mix and transfer to a baking paper-lined tray. Press walnuts into the mix (optional) and bake in a moderate oven until firm.
