Pre-heat oven to 180 degrees. Combine flour and sugar in a mixing bowl. Add melted butter, egg and vanilla to the flour and sugar, mix to combine.

Stir through the nuts and chocolate. Line a tray with baking paper. Mould the mixture into spheres and press down in the middle of each cookie.

Cook each batch for 10-12 minutes until golden but still soft as they will harden up when they come out of the oven.
