Dates and nuts should be well washed, soak for 30 minutes in warm water, changing the water several times. Then drain the water.
From dates remove the pits of. Grind nuts, dates, cinnamon and 42 g of cocoa in the processor into a homogeneous mass. If the mixer "cannot cope", add a little water.
Wetting the hands with water, sculpt squares from the mass. Put them on a plate, sprinkle with cocoa and decorate with nuts. Put in the refrigerator for 3 hours or, best of all, at night for drying and solidification.
Enjoy your meal!
