In a Ball® Wide Mouth Pint Jar, combine the heavy cream, sweetener, vanilla extract, and salt.
Place the lid on the jar, twist closed tightly, and shake. Shake the mixture until it is about doubled in size and about the consistency of brownie batter. It should take around 5 minutes.
Place the jar in the freezer. It should be ready to enjoy in about 2-3 hours. Shake every 20-30 minutes to incorporate any mix-ins and prevent iciness.
