In a large bowl, whisk together the heavy whipping cream, sweetened condensed milk, vanilla extract, and a pinch of salt until smooth and creamy.

Gently fold in the crushed Oreos, ensuring they're evenly distributed throughout the mixture.

Pour the mixture into the Ninja Creami pint container, leaving some space at the top as the ice cream will expand while freezing.

Secure the lid and freeze the container for at least 24 hours, or until solid.

When ready, remove the pint from the freezer and let it sit for about 10 minutes to soften slightly.

Check for ice crystal formation; re-spin in the Ninja Creami if necessary.

Serve in bowls or cones, optionally topping with more crushed Oreos.
