Put approx. 3 to 5 large tablespoons of the vanilla ice cream in a bowl and add about 400 ml of milk. Add the cocoa powder (it can also be strawberry powder, depending on the desired flavor of the milkshake) and mix briefly with a hand blender or in the mixer attachment of a food processor. A nice layer of ice is created on top.
Put a scoop of ice in each of two large glasses and fill up the glasses with the shake.
Tip:
If you like, you can add whipped cream and chocolate sprinkles or a fruit slice to decorate it.
