    You can taste test the oats and coffee mixture and adjust the sweetness level. This version is not overly sweet and you get most of the sweetness from the Greek yogurt and chocolate.

    Add the rolled oats, iced coffee, milk and vanilla extract to a mixing bowl and combine well. If you prefer the oats on the sweeter side, add in the simple syrup. Then evenly distribute the oats into 3 containers, giving them a little room to expand. Cover and chill overnight in the refrigerator for approximately 10-12 hours.
