Add all ingredients to Ninja Creami pint. Blend well using a hand frother or by pouring into a shaker cup and shaking vigorously.
Place lid on pint and place in freezer for a minimum of 8 hours.
Remove from freezer, place on your NInja Creami machine and select the lite ice cream mode.
Add 1-2 tbsp. more Fairlife chocolate milk. Replace lid and spin on milkshake mode.
Your Creami should be perfectly smooth, creamy, and ready to eat, but if it's not quite at your preferred consistency, you can use the re-spin function until it is. Enjoy!
Notes
If you have the Deluxe Creami, multiply all ingredients by 1.5 to accommodate the larger pints.
