Add all ingredients to a blender and blend together until smooth.
Pour into your Ninja Creami container and place the lid on. Freeze on a level surface in your freezer for 18-24 hours.
Remove from the freezer and run warm/hot water along the outside of the container for 30 seconds. (This helps thaw the outer layer and process correctly).
Process on the LITE ICE CREAM setting. Scoop out and enjoy.
