Why and how to make oat milk yogurt at home fermented with live cultures that is thick and delicious for eating out of a bowl or for smoothies.
Sprinkle 2 tablespoons of gelatin into 2 cups of cold or room temperature oat milk.
Let sit for a minute or two, then mix well to combine. Blend gelatin/milk mixture with 6 more cups of oat milk for a total of 2 quarts.
Warm the oat milk/gelatin mixture to a culturing temperature of 108-110 °F/42-43 °C. Use a food thermometer to check the temperature as needed.
Stir in the nondairy starter culture and ferment for 8 hours or overnight in a yogurt maker or a slow cooker with a yogurt setting (I use this one).
The yogurt will still be quite runny when fermentation is complete. To thicken it up, chill in the refrigerator for several hours or overnight.
Eat and enjoy! The deliciously thick, mild tasting nondairy yogurt stays good refrigerated for up to one week.
