Combine all ingredients in a food processor and grind. Roll into ropes with a diameter of approx. 2 cm (1 inch) and roll them through the extra sugar. Wrap them in plastic wrap and place them in the refrigerator for 1 hour to firm.
Preheat the oven to 180°C (350°F/Gas 4). Cut the rolls into slices, and garnish with a nut or cherry or whatever you have. Bake in the oven for 12 minutes until light brown. Leave to cool before serving.
