In a medium bowl, use a hand mixer on low speed or whisk to combine the milk, Sweetly® Stevia and salt until the stevia is dissolved. Stir in the heavy cream and vanilla. Cover, refrigerate, 1 to 2 hours, or overnight.
Turn the electric ice cream maker on; pour the mixture into the frozen freezer bowl and let mix until thickened, about 30 to 35 minutes. The ice cream will have a soft, creamy texture. If a firmer consistency is desired, transfer the ice cream to an airtight container and place in freezer for about 2 hours. Remove from the freezer about 15 minutes before serving.
