Stir in the flour

Roughly chop the macadamia nuts & cranberries before adding to the mixing bowl. Bring the mix together as a dough

Halve the dough and shape each half into a log about 5cm across. Wrap in cling film, then chill for an hour or freeze for up to 3 months

Pre-heat the oven to 180ºC/350ºF fan/Gas mark 4

Slice the logs into 1cm-thick rounds, place on a baking tray lined with baking parchment and bake for 12-15 minutes

Remove from the oven, leaving the cookies on the tray for 5 minutes before transferring them to a wire rack to cool completely
