In a jug or small bowl, whisk together the whole milk, heavy cream, confectioners’ sugar, and vanilla extract until the sugar is completely dissolved.
1 cup whole milk, ¾ cup heavy cream, ⅓ cup confectioners’ sugar, 1 teaspoon pure vanilla extract
Pour the mixture into a Ninja Creami pint container, stopping just below the maximum fill line. Place the container on a completely flat surface and freeze for 24 hours, or until fully solid.
Remove the lid and insert the frozen pint into the Ninja Creami machine. Process using the Ice Cream setting.
Once the first cycle is complete, create a small well in the center of the ice cream. Add the crushed Oreo cookies along with 1 to 2 tablespoons of milk to help the mix-ins blend smoothly.
6 Oreo cookies
Run the Mix-In setting until the cookies are evenly incorporated.
Serve immediately for a soft, creamy texture, or return the ice cream to the freezer for 1 to 2 hours for a firmer consistency.
