== Directions ==
=== Crust ===
# Preheat oven to 350°F.
# Wrap outside of 9-inch-diameter spring-form pan with 2¾-inch-high sides with double thickness of foil.
# Spray bottom of pan with vegetable oil spray.
# Finely grind cookies in processor.
# Add butter and process until blended.
# Press mixture onto bottom (not sides) of prepared pan.
# Refrigerate while preparing filling.
=== Filling ===
# Combine cream and coffee powder in medium saucepan.
# Stir over medium heat until coffee powder dissolves.
# Reduce heat to low.
# Add chocolate; whisk until chocolate melts and mixture is smooth.
# Cool 10 minutes.
# Using electric mixer, beat cream cheese and sugar in large bowl until well blended.
# Beat in cornstarch.
# Add sour cream and vanilla; beat well.
# Add eggs 1 at a time, beating just until blended after each addition.
# Whisk 1 cup cheese mixture into chocolate mixture.
# Return chocolate mixture to remaining cheese mixture; whisk until smooth.
# Pour batter into crust (this filled my spring-form pan all the way up but the cake did not run over while baking).
# Place spring-form pan in large baking pan.
# Add enough hot water to baking pan to come halfway up sides of spring-form pan.
# Bake cheesecake until softly set and slightly puffed around edges, about 1 hour.
# Turn off oven.
# Let cake stand in oven 45 minutes.
# Transfer spring-form pan to rack and cool.
# Cover; chill cake overnight.
=== Glaze ===
# Bring cream to boil in heavy small saucepan. Remove from heat.

# Pour glaze over top of cake. Using spatula, smooth glaze evenly over top. 
# Refrigerate until glaze is set, at least 2 hours. (Can be prepared 1 day ahead. Cover and refrigerate.)
# Using knife, cut around sides of pan to loosen cake. 
# Remove pan sides. Cut into wedges and serve.
