Tips
The easiest way to make this drink is with either a stand mixer or hand mixer. You can use a whisk to whip it by hand, but it will take 10 to 20 minutes. With a mixer, it takes less than five minutes.
You can enjoy the drink as its served, or you can stir the creamy whipped topping into the milk. Stirring it definitely dilutes the strong flavor.
You can save the extra whipped coffee. It will keep in the refrigerator for a day or so.
