Brew some fresh coffee - we used the Starbucks Cafe Verona pods that are compatible with your Nespresso machine.
Pour your Heart of Darkness liqueur into your glass, followed by your coffee. Give it a brief stir to combine the two.
I like to thicken my cream up a little - not straight out the bottle, but not whipped. Pour this over the back of a spoon into the glass, to create a floating layer of cream.
Finely grate some good quality dark chocolate - we used Lindt 70% cocoa chocolate. Sprinkle on top.
