Bake at 375 degrees F for 8 minutes.
remove from the oven and cool to room temperature.
Take the ice cream out of the freezer and let it soften slightly. Fill the cookie crust with the coffee ice cream. Then place the pie in the freezer for 15 minutes.
Remove from the freezer and pour the warm fudge over the top of the ice cream. Then put the pie back in the freezer to set for a few hours.
