Add all the dough ingredients minus the water to a food processor and blitz until it has the texture of coarse crumbs. Add the water and keep processing until the dough forms a ball. Wrap the dough ball in cling film and chill in the fridge for 10 minutes.
In a small bowl combine the filling ingredients and stir until homogeneous. The butter needs to be really soft but not melted. If the butter at room temperature is still somewhat hard, microwave it for a few seconds to make it soft enough to stir easily.
Take the dough out of the fridge and place it on a floured surface. Roll out to a thickness of 2-3 mm, aiming for a rectangular shape.
Thinly spread the cinnamon filling all over the dough using a spatula. Roll up the dough the long side pressing it gently to keep it tight. Place the rolled-up dough in the fridge to chill 10 minutes.
Using a thread cut out the cookies every 5 mm. Gently flatten each cookie with a rolling pin to about 2 mm thick, aiming for a circular shape. Place cookies on an oven tray lined with baking paper and chill in the fridge for 10 minutes. Bake at 175°C for 20 minutes.
