Using your drip machine, brew a cup of coffee. Using Dunkin Donuts coffee beans will produce a drink that’s closer to the original, but you’re also welcome to use your favorite brand of beans.
While the coffee’s still hot, add a tablespoon of sugar and stir thoroughly. Adding the sugar now will help it dissolve all the way and not just collect at the bottom of your cup. After that, we recommend letting the mixture cool for at least 20 minutes.
Pour ice into a tall glass. Using a clear glass will let you watch the magic as you stir this tasty drink together!
Now pour in the coffee mixture and ¾ cup of cold milk. No need to steam or froth the milk -- just add it in and stir. That’s it! You’ve got a tasty Dunkin Donuts iced coffee to enjoy.
