Add cocoa powder and cream cheese to a large microwave-safe bowl and heat for 10 seconds to soften.
Add sugar and vanilla extract and use a spatula to stir for a minute or so (until it looks like frosting).
Next, slowly add in the heavy cream and milk, mixing until fully combined.
Pour the mixture into a CREAMi™ pint, put the lid on, and freeze for a full 24 hours.
To process, remove pint from freezer, take off lid, and refer to the Ninja CREAMi™ quick start guide for assembly and set up instructions. Select full and use the ice cream button and let process.
If ice cream is not creamy enough or powdery, the please re-spin. When processing is complete, remove from the machine, serve, and enjoy!
