From milk and cocoa powder to make hot cocoa. Strain and cool it. Boil coffee and, too, strain and cool. There shouldn't be lumps.
In the bowl, where we whisk the drink, pour the condensed milk, then cream.
Then cocoa, vodka and coffee. All beat with a dip blender until smooth. Refrigerate for a few hours to cool.
Can be served for dessert, coffee or as a separate drink.
