Add the 28 Oreos for the crust to a food processor and pulse until fine crumbs form. Add in the melted butter and salt and pulse until combined.
Transfer the crust mixture to a 10-inch springform pan and press evenly into the bottom and up the sides of the pan. I find that a flat bottomed and sided drinking glass helps with this.
In a large bowl or stand mixer fitted with a paddle attachment, cream together the cream cheese, sugar, vanilla, and salt until light and fluffy.
Scrape down the sides of the bowl and fold in the cool whip followed by the crushed Oreos and mix until combined and hardly any white streaks remain. The mixture will have a grayish tint to it.
Transfer the filling to the crust and spread out evenly and gently.
Add the chocolate chips and heavy cream to a medium microwave-safe bowl and microwave for 45 seconds, whisk together the ganache, microwaving for an additional 15 seconds if needed for the chocolate to fully melt. Let sit at room temperature for 15 minutes.
Pour the cooled ganache over the top of the cheesecake filling then refrigerate for at least 6 hours before slicing and serving.
Top with whipped cream and Oreos for garnish, if desired.
