adapted from Nigella Lawson
375g unsalted butter
200g Fairtrade or Green and Blacks milk chocolate
200g 70 per cent dark chocolate
6 large eggs
15mls vanilla extract
500g castor sugar
225g plain flour
2.5mls salt
300g chopped walnuts
Preheat oven to 180degC. Line pan with baking parchment. Melt butter and chocolate together in a heavy pan or microwave. In another bowl beat the eggs with the sugar and vanilla.
When the chocolate and butter have cooled a little, mix in the eggs and sugar and then the nuts and flour and salt. Pour into the lined pan.
Bake for 30 minutes until the top is crackled brown and the top gives slightly when pressed. Cut into pieces when cool.
I use a roasting pan measuring 14" long, 12" wide, and 2" depth. This mixture makes a lot of brownies. They freeze very well. I use 2 types of chocolate because I find it too intense with just the 70% chocolate.
