Infuse the Mint: In a medium saucepan, combine the heavy cream and milk over medium heat. Add the fresh mint leaves and let them infuse for 10 minutes, stirring occasionally. Once the mixture has taken on a minty aroma, remove the saucepan from the heat and discard the mint leaves.
Sweeten the Base: Stir the granulated sugar and vanilla extract into the milk and cream mixture. Whisk until the sugar is fully dissolved.
Chill the Mixture: Let the cream mixture cool to room temperature, then place it in the refrigerator for at least 2 hours or overnight. The colder the mixture, the smoother the ice cream will be.
Churn the Ice Cream: Once the mixture is chilled, pour it into your ice cream maker and churn according to the manufacturer's instructions. This should take about 20-25 minutes.
Add Chocolate Chips: When the ice cream reaches a soft-serve consistency, stir in the chocolate chips or chopped chocolate.
Freeze and Set: Transfer the ice cream into an airtight container and smooth the top. Freeze for 3–4 hours or until it is firm enough to scoop.
Serve and Enjoy: Once set, scoop the Mint Chocolate Chip Ice Cream into bowls or cones, and enjoy the refreshing mint and chocolate crunch!
