Place the cream cheese in a large mixing bowl and microwave it for about 10 seconds to soften. This will make it easier to blend smoothly into the mixture.
Add the sugar to the softened cream cheese and stir until the mixture is cohesive and creamy. Gradually pour in the whole milk and heavy cream, whisking continuously to ensure everything is well incorporated and silky in texture.
Stir in the vanilla bean paste until fully combined, distributing the aromatic flavor evenly throughout the base.
Pour the prepared mixture into your Ninja Creami pint container, secure the lid tightly, and place the pint on a flat, stable surface in the freezer. Allow it to freeze undisturbed for a full 24 hours.
When ready to churn, remove the pint from the freezer and take off the lid. Assemble your Ninja Creami machine as outlined in the quick start guide, ensuring everything is locked into place. Select the "Ice Cream" function and allow the machine to complete its cycle.
After processing, check the texture. If needed, use the “Re-Spin” function for a creamier consistency. Once it reaches your desired texture, scoop directly from the pint and serve immediately for the freshest results.
