Using a stand mixer, cream the low-fat spread, caster sugar and light brown soft sugar in a large mixing bowl until smooth and thick. Beat in the egg and vanilla extract, then sift in the flour and a large pinch of salt and mix until just combined. Stir in the chopped chocolate. Cover and chill for 3 hours.

Preheat the oven to 200°C, fan 180°C, gas mark 6. Line two baking sheets with baking paper. Form the mixture into 16 walnut-sized balls and put them on the sheets, leaving plenty of room for the cookies to spread. Use the back of a wet spoon to flatten the tops of the cookies slightly, then bake for 10-12 minutes or until golden at the edges.

Leave the cookies on the baking tray for 5 minutes to firm up, then transfer to a wire rack to cool completely.
