Pre-heat oven to 180°C.

Sift plain flour into a large mixing bowl.

Add the sugar and chocolate chips and mix together.

Rub in the butter and bring mixture together to form a dough.

Pull chunks off the dough ball (to preferred size).

Roll chunks into a ball and place them on a baking sheet, flattening them to the size you want.

Bake in the centre of the oven for 15 minutes or until golden brown.
