Step 1

Place the flour, sugar, and butter into a food processor fitted with a metal blade and process until all the butter has been incorporated and the mixture resembles fine breadcrumbs. If you don't have a food processor use a mixing bowl and use your fingers to rub the butter into the flour and sugar.

Step 2

Tip the mixture into a mixing bowl and add the chocolate chips and the nuts.

Step 3

Now you need to get your hands in and squeeze the dough until it starts to come together and hold its shape. You may think it will never come together, but just persevere and it will form a dough eventually. (See notes)

Step 4

Divide the dough in half and roll each piece into a sausage shape.

Step 5

Wrap each sausage in greaseproof paper or clingfilm and place in the refrigerator to chill for 30 minutes.

Step 6

When the dough has chilled, preheat the oven to 190°C / 375°F

Step 7

Once the dough has chilled, unroll the wrapping and cut the dough into approximately 1cm slices. You should get 30 cookies from this mixture, depending on how thick you make the sausage shape.

Step 8

Arrange the cookies on a baking tray lined with baking parchment. If you don't have baking parchment rub the tray with a little butter or oil to prevent the cookies from sticking.

Step 9

Place the baking tray into the preheated oven and bake the cookies for 12 to 15 minutes. They will be done when they start to turn brown around the edges.

Step 10

Remove the tray from the oven and transfer the cookies to a cooling rack until they are cold. They will harden on cooling.
