Pour prepared Microwave Chocolate Ganache into Oreo pie crust and spread evenly up sides and bottom of crust. Refrigerate for one hour or until mostly set.TIP: I like to prepare a full recipe of the chocolate ganache as I always find a way to put it to use. Drizzling some over the top of this cheesecake would be delicious!
In a medium bowl, add pumpkin, spices, whipped topping, cream cheese and powdered sugar.
Using an electric or hand mixer, beat together on medium speed until combined. TIP: You want to mix until all ingredients are fully incorporated and no lumps remain in the cream cheese mixture.
Spoon cheesecake filling over chocolate ganache and spread evenly over pie crust. Refrigerate for two hours, or until completely set.
Before serving, spread additional whipped topping over center of cheesecake and garnish with shaved chocolate, if desired.
