In a small saucepan, add milk of your choice and add date and cocoa powder. Bring to a slow simmer for five minutes, stirring a couple of times.
Transfer the milk mixture to a blender. IMPORTANT -Tilt the blender lid slightly so it is ajar - this is needed for proper venting when you blend the hot chocolate. Blend for about 30 seconds on medium settling, as this step helps to incorporate the date into the hot chocolate.
Pour into a serving cup and top with a dollop of whipped cream and a dusting of cocoa powder if desired.
