Make the Ice Cream Base:
In a bowl, whisk together heavy cream, whole milk, sugar, vanilla, and salt until the sugar dissolves.
Pour the mixture into your Ninja Creami pint container (don’t exceed the max fill line).
Freeze the Base:
Seal the lid and freeze for 24 hours, until the base is completely solid.
Creamify the Base:
Remove the pint from the freezer and place it in the Ninja Creami machine.
Select the "Ice Cream" function.
If the texture is crumbly, use the "Re-spin" button. Repeat as needed until creamy.
Add the Oreos:
Make a small well in the center of the ice cream.
Add crushed Oreos and run the "Mix-In" function to blend them evenly.
Scoop & Serve:
Enjoy right away, or store in the freezer for later.
