Oreo Ultimate Turtle Cheesecake

Step 1
Preheat the oven to 325 degrees F (165 degrees C).

Step 2
Mix crushed Oreos and butter together until well combined; press onto the bottom and 2 inches up the sides of a 9-inch springform pan.

Step 3
Microwave caramels and milk in a microwave-safe bowl on high until caramels are completely melted and mixture is well blended, about 3 minutes, stirring after each minute. Stir in nuts. Pour 1/2 of the mixture into the crust and refrigerate for 10 minutes. Refrigerate the remaining mixture separately.

Step 4
Beat cream cheese, sugar, and vanilla with an electric mixer until blended. Add eggs, one at a time, mixing on low speed after each addition just until blended. Pour into crust over caramel layer.

Step 5
Bake in the preheated oven until the center is almost set, 65 to 70 minutes. Run a knife around the rim of the pan to loosen cake; cool before removing the rim. Refrigerate for 4 hours.

Step 6
Microwave reserved caramel mixture for 1 minute, then stir. Pour over cheesecake, then drizzle melted chocolate over top.
