In a high speed blender, combine all of the ingredients and blend until smooth. Taste test and add more dates (can also use honey or pure maple syrup) if you prefer a sweeter taste. Add a pinch of salt, if desired. Blend again.
Pour contents of blender into Ninja Creami containers. It should fill 2 of them. Freeze for at least 8 hours, or overnight.
Blend in the Ninja Creami on the Lite Ice Cream setting. The first run will likely look a bit powdery. Add a splash of milk and blend again. At this point it should be smooth and have a scoopable texture. If not, use the respin button to blend once more. Serve immediately and enjoy!
