Cook your sweet potato until soft, then let it cool completely.
Add the sweet potato, Greek yogurt, Fairlife milk, protein powder, vanilla, pumpkin pie spice, salt, and sweetener to a blender.
Blend until completely smooth and creamy.
Pour into your Ninja Creami pint, staying below the max-fill line.
Freeze on a level surface for at least 24 hours.
Spin on scoop and Ice Cream.
If it comes out crumbly, add 1–2 tbsp of Fairlife milk and Re-Spin until creamy.
Top with crushed graham crackers, mini marshmallows, and a sprinkle of pumpkin pie spice for that sweet potato pie vibe!
