Add all of the Ice Cream Base ingredients to a blender and blend until smooth.
Pour the mixture into your Ninja Creami pint and freeze for 24 hours on a level surface.
Take the pint out of the freezer and run it under hot water for 1-2 minutes (all sides, including the bottom).
Spin on Lite Ice Cream mode.
Respin 1-2 times until smooth and creamy.
Create a well in the center of your ice cream and add in the finely chopped chocolate. Spin on Mix-In mode.
Top it off with your pieces of assorted chocolate and enjoy!
