In a blender, add 2 cups (500 ml) of cold milk, 4 tablespoons of Nutella, and 1 cup (100 grams) of crushed ice.
Blend the mixture until it becomes smooth and frothy.
Pour the Nutella Shake into two tall glasses.
Optionally, you can garnish the shake with whipped cream, a drizzle of Nutella, and chopped hazelnuts.
