Add all the ingredients to a blender and blend until smooth.
Pour into your Ninja Creami pint and freeze for 24 hours.
Mix on the ice cream setting.
Once finished it will likely be a powdery texture. Give it a little taste and if it's not sweet enough, add more sweetener along with a tablespoon of your chocolate protein shake and "re-spin"
Notes
You can use an premixed protein shake you'd like
wait until the re-spin to add any extra sweetener. You will use much less this way.
if the ice cream is powdery, do not worry. Just add 1 tbsp of your chocolate protein shake and respin.
I recomend using chocolate fudge pudding mix because it adds a richer flavor.
