Brew a double shot (or triple shot, or quad shot) of espresso using an espresso machine, Nespresso machine, Moka pot, Aeropress or instant espresso powder.
Pour cold coffee milk into a milk frothing pitcher and steam using a steam wand. You could also froth the milk inside an aerroccino, or microwave the coffee milk for 60 seconds in the microwave and froth with a handheld milk frother until thick and frothy.
Pour the steamed/frothed coffee milk over the espresso, and enjoy your homemade hot Dunkalatte!
Optional: top with whipped cream and a chocolate covered espresso bean
