Method
 

Step 1: Preheat your oven to 180°C (350°F) and lightly grease a 9×13-inch baking dish.
    Step 2: Spread the crushed Oreo cookies evenly across the bottom of the baking dish, creating a thick base layer.
      Step 3: Pour the sweetened condensed milk evenly over the Oreo layer, making sure it reaches the edges.
        Step 4: Sprinkle the dry chocolate cake mix evenly over the condensed milk layer without mixing.
          Step 5: Distribute the sliced butter evenly over the top of the cake mix, covering as much surface area as possible.
            Step 6: Place the baking dish in the oven and bake for 40–45 minutes until the top looks set and slightly crisp while the center remains gooey.
              Step 7: Remove from the oven and allow the cake to cool slightly before serving.
                Step 8: Serve warm with a generous spoonful of whipped topping on top.
