Mix the yogurt with the trivia in a medium bowl, add in extract to taste. If you have a vanilla bean, add the scrapings here.
Thin "ice cream" base out with either almond milk or water (should only take about ¼ cup or so. you want the consistency to be that of a normal ice cream base)
Allow to site in fridge for at least an hour so that the stevia/sugar blend dissolves.
Place in ice cream maker until soft set, about 20 mins ( i like mind more on the harder side, it will melt fast as you serve it)
Store any remaining leftovers in freezer.
Notes
When thawing ice cream, it will take longer than regular ice cream sue to the high protein content
