In a medium saucepan, heat 750ml of the milk to almost boiling. Remove from the heat and stir in the Hazelnut Chocolate Spread.
Leave to melt for about 30 seconds then whisk for 2-3 minutes until the milk and spread are blended, smooth and creamy.
Pour into four heatproof glasses or mugs.
With a milk frother whisk the remaining plain milk until doubled in size and very frothy. Spoon onto the hot hazelnut chocolate milk and enjoy.
On a hot day, make the chocolatey drink with all the milk, cool and chill. Serve topped with a scoop of vanilla ice-cream.
