In a mixing bowl, whisk together the heavy cream, whole milk, sugar, and vanilla extract until the sugar is dissolved.

Cover the mixture and refrigerate for at least 2 hours or until well chilled.

Pour the chilled mixture into the ice cream maker and churn according to the manufacturer's instructions.

If desired, add chocolate chips or nuts during the last few minutes of churning.

Transfer the churned ice cream to an airtight container and freeze for at least 2 hours to firm up.

Scoop and serve as desired.
