Heat the golden syrup and spread in a small saucepan over a gentle heat until melted, stirring. Allow to cool slightly.
Mix all the remaining ingredients together in a large bowl. Pour in the syrup mixture and mix to form a soft dough. Place 14 spoonfuls of the mixture well spaced apart on a large baking sheet lined with baking parchment and gently press with the back of a spoon to flatten slightly. Bake in a preheated oven, 180°C (350°F), Gas Mark 4, for 8–10 minutes until pale golden.
Leave the cookies to cool on the baking sheet for 5 minutes until firm, then transfer to a wire rack to cool completely.
