Use the Vivalto Lungo capsule to make a lungo (110ml) in a cup.
While making the lungo, froth the milk in a jug using the steam wand of your Nespresso machine or your Aeroccino milk frother (if it's the Aeroccino 4, press the 2nd button on the right).
Pour the chocolate cookie syrup into your glass and add the lungo.
Add the steamed milk and froth.
Crumble the cookie on top.
