Pour the whole milk, heavy cream, vanilla bean paste, sugar, cream cheese, and strawberries into a small blender and blend until all of the ingredients have combined together. Pour the mixture into a Ninja Creami pint container.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit. To avoid getting a bump on the top of the frozen mixture, freeze with the lid off of the container.
Process the Ice Cream
After 24 hours, remove the pint container from the freezer.
Place the pint container into the outer bowl of the Ninja Creami and then process on "ICE CREAM."
If the ice cream is dry or crumbly looking (like sand), pour in a tablespoon or two of milk and then re-spin. If the ice cream looks like little balls of ice cream, respin without adding liquid. You may have to repeat this process a couple of times.
