To make the cubes need:
A glass of milk, or a jug, semi-skimmed, skimmed or soy milk. You could also use vanilla or coconut cream for example.
Containers for cubes, you can use custom to give a touch of fun ways.
First get rid biscuits in a bowl, using your hands, a spoon or a mortar, we can leave small pieces so that then we can taste it in the drink.
We add the pieces to the glass or jug of milk, and pour over ice buckets or containers for ice. Let freeze for several hours.
Serve the drink freshly made, so that the ice melts and the flavors are based.
