Add all ingredients listed under "Ice Cream Base" to your Ninja Creami pint and whisk or froth to combine. Alternatively, you can add the ingredients to a blender and blend before pouring the mixture into your pint!
Put the lid on your pint and freeze for 24 hours on a level surface.
Run your pint under hot water for 1-2 minutes to thaw it slightly for a smoother result.
Spin on lite ice cream mode.
Respin 1-2 times, until the ice cream is smooth and creamy.
While your ice cream is spinning, add the ingredients listed under "Red Velvet Cake Mix-In" to a bowl and mix.
Once combined, microwave for 30-45 secs.
After removing your cake from the microwave, use a fork to crumble it up to be added to your ice cream!
When your ice cream is done spinning, create a well in the center if there is not one already there and add in your red velvet cake, reserving a few pieces for the top if you would like!
Now, spin the ice cream one more time on mix-in mode.
Top it off with any remaining red velvet cake pieces and enjoy!
