Chocolate Chunk Cheesecake

2 cups finely crushed cream-filled Oreos (about 20 cookies)

2 T butter, melted

4 (8oz.) packages cream cheese, softened

1 ½ cups sugar

4 eggs

2 tsp. vanilla

1 ¾ (11.5- oz package) semisweet chocolate chunks, divided

1 ½ cups coarsely crushed Oreos (about 14 cookies)

1/3 cup whipping cream

Stir together 2 cups cookie crumbs and butter; press mixture into bottom and ½ inch up sides of a 9-inch springform pan.

Beat softened cream cheese and sugar at medium speed with an electric mixer until blended. Add eggs, 1 at a time, beating just until blended after each addition. Stir in vanilla, 1 cup chocolate chunks, and 1 ½ cups coarsely crushed cookies. Pour into prepared crust.

Bake at 325 degrees for 55 minutes or until center is almost set. Turn off oven; let cheesecake stand in oven, with oven door partially open, 20 minutes.

Remove cheesecake from oven, and cool in pan on a wire rack 30 minutes. Cover cheesecake, and chill 8 hours. Release sides of pan.

Microwave remaining ¾ cup chocolate chunks and whipping cream in a glass bowl at HIGH 1 minute; stir until chocolate melts. Chill 30 minutes. Pour over cheesecake.
