Mix the Base: In a medium bowl or the Ninja Creami pint itself, microwave the softened cream cheese for 10 seconds to make it easily mixable. Whisk the cream cheese and sugar until smooth and no lumps remain.
Combine Ingredients: Whisk in the vanilla bean paste and salt. Slowly pour in the heavy cream and whole milk, whisking continuously until the mixture is completely smooth and the sugar has dissolved.
Freeze: If you mixed in a separate bowl, pour the base into the Ninja Creami pint container. Secure the lid and transfer the pint to a level surface in your freezer. Freeze for at least 24 hours until frozen solid.
Process: Once frozen, remove the pint from the freezer and take off the lid. Place the pint into the outer bowl of the Ninja Creami, attach the Creamerizerâ„¢ Paddle lid, and lock it into the machine.
Spin: Select the ICE CREAM function and let the machine process the full cycle.
Check and Re-spin (If Needed): After the first spin, the ice cream might look crumbly. This is normal. Add 1-2 tablespoons of milk or heavy cream, place it back in the machine, and use the RE-SPIN function. This second spin is often key to achieving a perfectly smooth and creamy texture.
Serve or Store: Serve immediately for a delicious soft-serve consistency. For a firmer, more traditional scoopable ice cream, transfer the pint back to the freezer for 30-60 minutes.
