Crush ¾ of the Oreo cookies in a food processor or by placing them in a zip-top bag and crushing them with a rolling pin until the cookies are broken down into very small pieces. Set the remaining Oreos aside for later.

In a medium bowl, mix the large portion of Oreo crumbs with the melted butter and the fudge until well combined.

Press the Oreo crumb mixture into the bottom of a 9x13-inch pan, using a flat-bottomed glass to press it evenly. Chill in the refrigerator while preparing the filling.

In a large bowl, beat the cream cheese with an electric mixer until smooth. Add the powdered sugar and vanilla extract, and beat until well combined.

In a separate bowl, whip the heavy cream until stiff peaks form. Fold ½ of the whipped cream into the cream cheese mixture until well combined.

Pour the filling into the prepared crust and smooth the top.

Add milk, sweetened condensed milk, and chocolate pudding mix into a bowl and whisk together until nice and even. Add the pudding mixture on top of the cream cheese layer.

Put the remaining Oreo cookies into a zip-top bag and crush them into large pieces.

Top with the remaining whipped cream, and sprinkle the reserved crushed Oreos on top.

Cover and chill the dessert in the refrigerator for at least 2 hours or until set.

Once set, slice and serve while cold. Enjoy!
