For best results, ensure the mixture is completely cool before churning to prevent ice crystals from forming too quickly.
If you do not have an ice cream maker, you can freeze the mixture in a shallow container in the freezer, stirring vigorously every 30 minutes with a fork to break up ice crystals for about 4 hours.
Store any leftovers in an airtight container in the freezer for up to one month. Let sit at room temperature for 5-10 minutes before scooping for easier serving.
