In a blender, add 500 ml of cold milk, 4 scoops of vanilla ice cream, and 2 tablespoons of sugar. You can adjust the sugar according to your taste preference.
Blend the mixture until it becomes smooth and creamy.
Pour the milkshake into tall glasses, leaving some space at the top.
Add a dollop of whipped cream on top of each glass and garnish with a cherry or a sprinkle of chocolate shavings.
Serve the milkshake immediately with a straw and a long spoon.
