In a mixing bowl, combine the heavy cream, whole milk, sugar, vanilla extract, and salt. Whisk until the sugar is fully dissolved.

Cover the mixing bowl and refrigerate the mixture for at least 2 hours.

Once chilled, pour the mixture into the Ninja Creami container.

Place the container in the freezer and freeze for at least 4 hours, or until completely solid.

Remove the container from the freezer and attach it to the Ninja Creami base. Select the "Ice Cream" function.

Check the consistency after processing. If it's too soft, run it through the machine again.

Enjoy your ice cream right away or transfer to an airtight container for storage.

Scoop out the ice cream and pair it with your favorite toppings.
