Oreo Swirled Cheesecake

Directions

1. 1
   Preheat oven to 350F. Pulverize Oreos in a food processor. Press cookie crumbs into the bottom of an 8 inch springform pan. Use the back of a spoon to press the cookie crumbs into a solid.
2. 2
   Bake for 10 minutes. Then turn the oven down to 300F.Put all remaining ingredients except cocoa in a mixer.
3. 3
   Mix on high for 5 minutes or until smooth. Put 2 cups of the batter in a new bowl and mix in the cocoa.Use a large sheet of aluminum foil to cover the outside of the springform pan. Repeat with a second sheet of aluminum foil.Spoon about half of the vanilla batter on top of the crust. Then spoon about half to two-thirds of the chocolate batter on top of the vanilla batter. Cover with the remaining vanilla batter. Then swirl the remaining chocolate batter on the vanilla batter. If you want a decorative look, spoon the chocolate batter in lines and then use a knife to cut across the lines.

   Place the pan in a larger pan (I use a cast iron skillet) and place in the oven. Use a measuring cup to fill the outer pan with water.
5. 5
   Bake for 1 hour 45 minutes until the center is still jiggly but the outer inch is solid.
