- 225g dark cooking chocolate
- 115g unsalted butter
- 4 large eggs
- 1/4 teaspoon salt
- 1 1/4 cup white sugar
- 1 1/2 teaspoons vanilla extract
- 3/4 cup all-purpose or plain flour
- 1 cup chopped walnuts (optional)
Grease and flour a 23cm square baking tin or casserole dish. Heat oven to 170C.
Melt chocolate and butter in a bowl or pan over simmering water, stirring until smooth and glossy.
In a mixing bowl beat eggs with salt, sugar and vanilla until the mixture becomes thick and is a nice pale colour. Stir in the melted chocolate and butter mixture then fold in the flour and walnuts.
Bake for about 25 minutes, or until a toothpick comes out nearly clean when inserted in the centre.
