1. In a mixing bowl, whisk together heavy cream, whole milk, granulated sugar, vanilla extract, and a pinch of salt until the sugar is fully dissolved.
2. Pour the mixture into the Ninja Creami machine.
3. Follow the manufacturer's instructions for your Ninja Creami to churn and freeze the ice cream. This typically takes about 20-25 minutes.
4. Once the ice cream reaches a soft-serve consistency, transfer it to a lidded container and freeze for an additional 2-3 hours or until firm.
Making ice cream at home allows you to choose high-quality ingredients, control the level of sweetness, and avoid additives or preservatives commonly found in commercial ice creams.
