Preheat oven to 350°F. Grease a 9-inch springform pan with nonstick cooking spray.
In a medium bowl, mix together crushed Black & White cookies and melted butter. Press the mix onto the bottom of the prepared pan. Bake for 10-15 minutes or until golden brown. Remove from oven and let cool.
In a large mixing bowl, beat the softened cream cheese until creamy. Gradually add sugar, whiskey, heavy cream, vanilla extract, and cocoa powder. Mix until well blended. Add eggs one at a time, mixing on low speed after each addition until just blended.
Pour the cream cheese mixture over the cooled crust. Smooth the top with a spatula.
Bake for 45-50 minutes or until the center is almost set.
Remove from the oven and let the cheesecake cool for 10 minutes. Loosen the edges of the cheesecake from the pan with a knife. Let the cheesecake cool completely at room temperature then refrigerate for at least 4 hours or overnight.
Before serving, sprinkle the top with toasted sliced almonds.
