Add all ingredients to the Ninja Creami container and stir to combine.
Place lid on, and freeze on a level surface in the freezer for at least 18 hours.
Remove from the freezer, run warm/hot water along the outside of the container to thaw the outer layer.
Process on the LITE ice cream setting. If needed, add a splash of milk and respin.
Notes
If you want more protein, add some vanilla or unflavored protein powder.
Highly recommend running warm/hot water along the outside of your Creami container before processing. This will allow the outer layer to thaw and get properly incorporated when the ice cream spins.
If you have leftovers, smooth out the top and return to the freezer. You may need to process again before serving.
