In a mixing bowl, combine the Oreo instant pudding mix with 1 cup of milk. Whisk together until smooth and set aside for about 5 minutes to allow it to thicken.
In another bowl, use an electric mixer to beat the cream cheese until it’s creamy and free of lumps.
Once the pudding has thickened, gently fold it into the whipped cream cheese until well combined.
Next, fold in the Cool Whip until fully incorporated.
Gently fold in the crushed Oreos, making sure they’re evenly distributed throughout the fluff.
Transfer the Oreo fluff to your serving dish and refrigerate for at least 2 hours, allowing it to set. Serve chilled, and enjoy the deliciousness!
