Preparation
Preheat oven to 325°. Wrap a double thickness of heavy-duty foil (about 18 in. square) around a greased 9-in. springform pan. Mix cookie crumbs and sugar; stir in butter. Press onto bottom of prepared pan.
To prepare filling, microwave chocolate chips on high until melted, about 1 minute. Beat cream cheese and sugar until smooth. Add flour; mix well. Add eggs and vanilla; beat on low speed just until blended. Measure out 2 cups batter, and stir in coffee liqueur; add melted chocolate chips and stir until blended. Pour over crust. Add Irish cream liqueur to remaining batter; spoon over chocolate layer. Place springform pan in a larger baking pan; add 1 in. hot water to larger pan.
Bake until center is just set and top appears dull, 60-75 minutes. Remove springform pan from water bath. Cool cheesecake on a wire rack 10 minutes. Loosen side from pan with a knife; remove foil. Cool 1 hour longer. Refrigerate overnight, covering when completely cooled.
For ganache, microwave chocolate chips and whipping cream on high until chips melt; cool slightly. Remove rim from pan; spread ganache on chilled cheesecake.
