Grease a 9x13-inch glass baking dish with butter and set aside.
In the bowl of a food processor, pulverize the Oreo cookies until small even crumbs form. Add the melted butter to the cookie crumbs and pulse until combined.
Press the crust mixture into the prepared baking dish and place it in the freezer to chill while preparing the next layer.
With a hand mixer, beat together cream cheese, powdered sugar, cocoa powder, vanilla extract, and the cream. Continue beating until the mixture is smooth and fluffy.
Spread the chocolate cheesecake layer over the chilled crust.
Use a spatula to carefully spread the cherry pie filling evenly over the cheesecake layer (if the cheesecake layer appears too soft, you can chill the dish in the freezer for 15 minutes or so between each layer to help firm up the surface.
Top with the Cool Whip, reserving about a cup to pipe swirls on top of the lush if you wish.
Spread the Cool Whip smooth. Sprinkle with chocolate sprinkles.
Use a piping bag and tip #1M to pipe soft swirls of Cool Whip on top of the lush.
Place the lush in the freezer to firm up for at least 2 hours.
Gently place a cherry on top of each piped swirl.
Cut into pieces and serve.
