Place chocolate in a glass bowl and melt over gently simmering water. Make sure that the bowl does not touch the water.
Mix cocoa with some of the milk to form a paste and mix with remaining milk and vanilla. Stir some of the melted chocolate into the milk mixture until smooth. Mix into the warm chocolate.
Stir in dates and coconut. Place spoonfuls of the mixture onto baking paper and sprinkle with coconut or cocoa and allow to set. Alternatively allow to cool
slightly and then roll into balls. Roll balls into extra coconut or cocoa, if preferred. Allow to cool in the fridge. Serve 1–2 balls as a treat.
