In a bowl, mix crushed chocolate cookies with melted butter and granulated sugar (if using).
Press mixture into a 9-inch pie dish to form the crust. Bake for 10 minutes, then let cool completely.
Once cooled, spread softened coffee ice cream evenly over the crust.
Drizzle chocolate syrup over the ice cream layer.
Place the pie in the freezer for at least 4 hours or overnight to set.
Before serving, top with whipped cream, hot fudge sauce, and chocolate shavings.
Slice and enjoy!
Notes
For variation, substitute coffee ice cream with chocolate or vanilla. Allow the pie to sit at room temperature for a few minutes before slicing for easier serving.
