For a stronger blueberry flavor, blend 1–2 tablespoons of blueberry sauce directly into the frappuccino base. For a lighter version, use low-fat milk and skip the heavy cream. Freeze the serving glass for 10 minutes before assembling to keep the drink colder longer. The blueberry sauce can be stored in the refrigerator for up to 5 days in an airtight container.
