Iced coffee K cups can be brewed over ice to give a cold coffee drink. Fill a mug with ice, put it on the drip tray, and select the 'brew-over-ice' or 'Iced' setting. The Keurig will start brewing with hot water to extract the coffee flavor and then switch to cold water so the coffee cools. This should give you a cold brew without melting the ice and making it watery.
