After the mixture is blended, pour it into silicone ice cube trays (or regular trays) and place in the freezer until solid (about 1-2 hours). 2. Place the frozen ice cream cubes back into the container of your Vitamix and blend until an ice cream texture is achieved. You may need to add a touch more non-dairy milk to get the blending process started. Eat immediately or put it in an airtight container in the freezer to save for later.
