In a mixing bowl, dissolve Jell-O in boiling water.
Spoon in softened ice cream into the Jell-O and stir until melted and smooth.,
Chill until slightly thickened, about 10 minutes.
Pour into crust and chill until firm (2 hours).
Make the chocolate topping. You can choose from a chocolate ganache topping made with cream and chocolate or a mixture of melted margarine and chocolate. To make the ganache, heat the cream in the microwave or over the stove. Add chocolate to hot cream. Let stand for 2 minutes, then stir until smooth. If using margarine, melt margarine with chocolate by heating in the microwave and stirring at 30 second intervals.
Spread whichever chocolate mixture you've chosen over pie and allow it to chill until the chocolate hardens.
Garnish with whipped topping, chocolate pieces and fresh raspberries.
Notes
For a homemade crumb crust, mix 1 ½ cups of chocolate cookie crumbs (Nabisco Famous Wafers) with 6 tablespoons of melted butter. Press into a 9 inch pie dish and bake at 350 for 6 minutes. Let cool completely before using.For the chocolate topping, you can make a ganache using 56 grams of whipping cream and 56 grams of chocolate or you can melt 3 tablespoons of margarine with 2 oz of chocolate. I'm sure butter would work as well. We were glad we used the ganache topping because it was easy to fork into.
