Add milk, heavy cream, sugar, vanilla extract, cream cheese, and pudding mix into a bowl. Whisk everything until smooth. Make sure sugar dissolves fully. This creamy base creates rich texture and helps the Oreo flavor blend perfectly after spinning.

Take Oreo cookies and crush them into small pieces. You can use a food processor or a zip bag with rolling pin. Keep some larger chunks for crunch. The cookie crumbs will later mix beautifully into the smooth homemade ice cream.

Carefully pour the ice cream mixture into the Ninja Creami pint container. Do not overfill the container. Smooth the top with a spoon if needed. Close the lid tightly before placing the container inside the freezer for freezing.

Place the container flat in your freezer for twenty-four hours. This step is important for correct Ninja Creami texture. The mixture must become fully frozen before spinning. A properly frozen base creates creamy and smooth Oreo cookie ice cream later.

Remove the frozen pint from the freezer carefully. Place it into the Ninja Creami machine according to instructions. Select the “Ice Cream” setting. After spinning, the texture should become creamy and soft with rich cookies and cream flavor.

Create a small hole in the center of the ice cream. Add crushed Oreo cookie pieces into the middle. Use the “Mix-In” setting on your Ninja Creami machine. This spreads cookie chunks evenly throughout every delicious scoop of ice cream.
