Add chilled mixture to ice cream maker and churn according to manufacturer’s instructions - about 45 minutes. It should look like soft serve. If for some reason it doesn't thicken enough, put the mixture (still in the ice cream churning bowl) and pop it back in the freezer to thicken before churning once more.
Chill mixture in the freezer for 1.5-2 hours, or in the fridge overnight.
Add all ice cream ingredients to blender and blend until creamy and smooth, scraping down sides as needed. Use the “liquify” or "puree" setting if you have it. You want it to be completely creamy and blended.
The night before, place your ice cream churning bowl in the freezer to properly chill. Also, make sure you soak your cashews overnight OR the next day for at least 6 hours. Be sure to drain before adding to blender.
