Nigella Lawson make delicious gluten-free triple chocolate buckwheat cookies for the festive season on Simply Nigella Christmas Special.

Nigella says: “The star here is the buckwheat, not only because it makes these cookies gluten-free, but mainly because I feel it brings its own nutty flavour and unique texture, creating a cookie that has softness and a shortbready bite, as well as a subtle smokiness. Those who like a truly chewy cookie might find these a little cakey, but I like chewiness in a cookie and yet find constant excuses to make these.”

The ingredients are: 150g dark chocolate chips, 125g dark chocolate (minimum 70% cocoa solids), 125g buckwheat flour, 25g cocoa powder, sieved, ½ tsp bicarbonate of soda, ½ tsp fine sea salt, 60g soft unsalted butter, 125g soft dark brown sugar, 1 tsp vanilla paste or extract and 2 large free-range eggs, fridge-cold.
