Pour the milk, yogurt, vanilla bean paste, allulose, and guar gum into a small blender and blend until all ingredients are fully combined. Pour the mixture into a Ninja Creami container.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit.
Process the Ice Cream
After 24 hours, remove the Ninja Creami container from the freezer. If there is a large bump in the yogurt, melt or scrape the large bump so that the top is level.
Place the Ninja Creami container into the outer bowl of the Ninja Creami and then process on "ICE CREAM."
If the frozen yogurt is dry or crumbly looking (like sand), pour in a tablespoon or two of milk and then re-spin. If the frozen yogurt looks more like little balls of ice cream, re-spin without adding liquid. You may have to respin a couple of times.

Notes
Can zero sugar yogurt be used in the Ninja Creami?Yes, you can use zero sugar yogurt to make frozen yogurt. However, Ninja does not recommend using ONLY sugar-free or fat free yogurt. For this recipe we are adding several ingredients like milk, guar gum, and vanilla bean paste that will make it easier for the Ninja Creami to process the yogurt.Is frozen yogurt tangy or sweet?Low calorie frozen yogurt is a little tangy and a little sweet. If you would like it tangier, add less allulose. If you like it sweeter, add more allulose. Taste the mixture before freezing and adjust as needed.Can flavored yogurt be used to make low calorie frozen yogurt?You can switch it up and use yogurt that is already flavored, like strawberry, blueberry, or key lime pie. There are endless flavors of yogurt available. Just keep in mind that if you change the yogurt used, the nutritional information will also change.
