In a large mixing bowl, whisk together the heavy cream, whole milk, granulated sugar, vanilla extract, and salt until the sugar is fully dissolved.
If using, gently fold in the crushed vanilla wafers for added texture.
Pour the mixture into an ice cream maker and churn according to the manufacturer’s instructions, usually about 20-25 minutes, until it reaches a soft-serve consistency.
Transfer the ice cream to an airtight container and freeze for at least 4 hours or until firm.
Before serving, let the ice cream sit at room temperature for about 5-10 minutes to soften slightly for easier scooping.
