¼cupdark chocolate or semi-sweet chocolate chipsmelted
¼cupchopped pecanstoasted if desired
Preheat oven to 325°F. Crush the oreo cookies in a large freezer-weight zipclose bag. (You can use a rolling pin or mallet to crush them. Alternatively, you can quickly pulse them in a food processor.)
Combine the crumbs with the melted butter and press the mixture into the bottom of an 8-10" springform pan. Pour ½ cup of the caramel sauce over this crust and spread it out lightly with a spatula. Refrigerate the caramel-coated crust for 10 minutes.
Beat the cream cheese, sugar, and vanilla until smooth. Add the eggs, one at a time, mixing on low speed just until each one is blended. Pour this mixture over the refrigerated crust. Place the spring-form pan on a large baking sheet prior to placing it in the oven. (If you line the baking sheet with foil first, clean up will be a breeze.) Some of the caramel in the crust will drip through the pan onto your oven if you forget the baking sheet.
Bake 65-70 minutes, until the center is almost set. Run a knife around the edges of the pan while it is still warm. Let cool at room temperature and then refrigerate for 4 hours or overnight before removing the sides of the pan.
Once the sides of the pan have been removed, sprinkle the pecans across the top of the cheesecake and then drizzle with the remaining caramel and the melted chocolate. Store remaining cheesecake in the refrigerator. Enjoy!
I typically use a 9" springform pan and I have used a 10" pan for this cake as well in the past. It simply makes for a shorter height cheesecake. An 8" pan will work too, simply adjust the cooking time accordingly. The smaller pan may take as much as 10-15 minutes longer to cook.
