Line an 8-inch cake pan with plastic wrap, leaving extra hanging over the sides for easy removal later. Scoop the slightly softened ice cream into the pan, pressing it down evenly to eliminate air pockets. Cover tightly with plastic wrap and freeze until completely solid.

Bake an 8-inch chocolate cake layer using your preferred recipe or a quality box mix. Allow it to cool completely before assembly. If making homemade, combine wet ingredients in one bowl and dry ingredients in another, then mix together until just combined.

Place the cooled cake layer on your serving plate. Spread the room temperature fudge sauce evenly over the top, then sprinkle the chopped Oreo cookies over the fudge. Carefully remove the ice cream layer from the freezer and place it on top of the cake. Return to freezer while preparing whipped cream.

In a large mixing bowl, combine the cold heavy cream, powdered sugar, and vanilla. Using an electric mixer, start on low speed and gradually increase to high. Whip until soft peaks form, then finish by hand to achieve firm peaks. Be careful not to overwhip or the cream will curdle.

Remove the cake from the freezer and cover completely with the whipped cream, smoothing the top and sides. Transfer remaining cream to a piping bag with a large star tip. Create chocolate drips around the edge using warm fudge, then pipe decorative swirls along the top border. Press crumbled cookies around the bottom edge for a finished look.

The cake can be stored in the freezer until ready to serve. For best slicing results, remove from freezer and let sit at room temperature for about 15 minutes before cutting. Run your knife under warm water between cuts for cleaner slices.
