2 cups chopped brownies (with walnuts and frosting)
1 1/2 litres chocolate ice cream, softened
1 (6 ounce) graham cracker or chocolate pie crust
1/4 cup whipping cream
1 cup semi-sweet chocolate chips
1/2 cup whipping cream

Fold brownies into softened ice cream. Spoon mixture immediately into pie crust. cover and freeze until firm, 1 to 2 hours. Place pie in refrigerator 20 minutes before slicing.

Serve each slice of pie with a dollop of whipped cream then drizzle with 2 tablespooons warm Chocolate Sauce. 8 servings.
 

Chocolate Sauce: Combine chocolate chips and 1/2 cup whipping cream. Stir over low heat until smooth. Cool slightly. Serve warm. Makes 1 cup.
