Classic Mud Pie

chocolate cookie crust:
1 12 oz. pkg (2c) semi-sweet chocolate morsels, divided
3 TBS butter
1 ¼ c chocolate wafer crumbs

fudge sauce:
1 ½ c semi-sweet chocolate morsels, reserved from 12 oz pkg
½ c heavy cream
3 TBS butter
1 TBS coffee flavored liqueur (we used non-alcoholic jarred Starbucks Frappuccinos)

filling:
1 qt coffee ice cream, softened
2 TBS coffee flavored liqueur

chocolate cookie crust:
Combine over hot (not boiling) water, ½ c semi-sweet morsels and butter; stir until morsels are melted and mixture is smooth. Add chocolate wafer crumbs; stir until well blended. Press into 9-inch pie pan and chill until firm, about 35-45 minutes. (You can also just use an store-bought cookie crust, too!)

fudge Sauce:
Combine over hot (not boiling) water, remaining 1 ½ c semi-sweet chocolate morsels, heavy cream, and butter. Stir until morsels are melted and mixture is smooth. Remove from heat; stir in coffee flavored liqueur. Chill 10 minutes. Spread ½ c sauce on bottom of prepared chocolate cookie crust. Chill 15 minutes.

filling:
In large bowl, combine ice cream and coffee flavored liqueur. Spoon over fudge sauce layer and freeze several hours or until firm. Reheat remaining fudge sauce over hot (not boiling) water. Serve pie with warm fudge sauce and whipped cream.
