Add all "Ice Cream Base" ingredients to a blender and blend until smooth.
Pour the mixture into a Ninja Creami pint and freeze it on a level surface for 24 hours.
Once frozen, take the pint out and rinse the outside under hot water for 1-2 minutes (including the bottom).
Spin on Lite Ice Cream mode.
Respin 1-2 times until you reach your desired consistency.
If your ice cream doesn’t already have a well in the middle, use a spoon to create one. Add 4 Ritz crackers into the well and spin again on Mix-In mode
Crumble the last 2 Ritz crackers on top for extra crunch. And enjoy!
