Fill a glass to the top with ice, then add in the vanilla flavor. I typically use 2-3 Tbsp. I really like it sweet, but you would add the flavor to your taste.
Next, pour in the coffee then top it with the cream. Stir it up, and enjoy!
Note: The measurements are going to vary based on the size of the glass you use. This can be used with a variety of flavors as well.
