I have developed many cookie recipes, but none as delicious as this one. You pretty much can't go wrong. If you like, swap plain dark chocolate for sea salt-spiked dark chocolate - it works really well.Method
● Preheat the oven to 180°C and line two large baking sheets with non-stick baking paper.
● Cream the butter with the sugar in a bowl until light and fluffy, then add the egg and beat again.
● Fold in the remaining ingredients until well incorporated.
● Shape the cookie dough into 20 balls.
● Place on the prepared baking sheets, well spaced apart, and press down slightly to flatten.
● Bake for 10–12 minutes, until lightly golden but still slightly soft in the middle. Leave to cool on the sheets for a few minutes, then transfer to a wire rack to cool completely.
