Chocolate Pumpkin Cheesecake *

 Crust:

9 oz oreo cookies
2 Tbsp butter, melted

Filling:

16 oz plain cream cheese, at room temperature,
1 cup sugar
1 cup canned pumpkin puree
3 large eggs
3 Tbsp a.p. flour
1 Tbsp pumpkin pie spice
1/2 tsp salt
4 oz dark chocolate, chopped

Preheat oven to 350 degrees.  Line bottom and sides of 8-inch square baking dish with parchment paper, leaving overhang on all sides.  In a food processor, blend cookies until finely ground, add butter, and pulse until moistened.  Transfer crumb mixture to prepared pan and gently press into bottom.  Bake until fragrant and slightly firm, 12-14 minutes.  Set aside to cool.  Place cream cheese in food processor; blend until smooth.  Add sugar, pumpkin puree, eggs, flour, pumpkin pie spice and salt.  Process until combined.  Set aside.  Pour remaining pumpkin mixture into prepared pan.  Drop dollops of chocolate mixture onto pumpkin mixture, swirl.  Bake until cheesecake is set but jiggles slightly when gently shake, about 40-50 minutes.  Cool in pan.  Cover; chill until firm, at least 2 hours.  Using overhang, transfer cake to work surface.  With a knife dipped in water, cut into 16 squares.  Store in airtight container in refrigerator.  These can also be frozen and set out to come to room temperature before serving.
