Directions

1. Combine chocolate wafer crumbs and 4 tablespoons butter or margarine. Press the mixture into the bottom and partially up the sides of a 9 inch springform pan.
2. To Make Caramel Sauce: In a saucepan, combine 1/2 cup sugar and 3 tablespoons water. Cook over low heat, stirring constantly, until sugar is completely dissolved. Bring to a boil, and continue boiling without stirring until the syrup turns a light amber. While the syrup is boiling, brush down the sides of the pan from time to time to prevent crystal from forming. Remove the pan from the heat, and stir in hot cream. Continue stirring, over low heat if necessary, until all for the caramel is dissolved into the cream. Stir in 4 tablespoons butter or margarine, and set aside to cool slightly. Pour warm caramel sauce over the crust. Freeze until firm, about 30 minutes.
3. To Make Espresso Fudge Sauce: Combine chocolate, cocoa, 4 tablespoons butter or margarine, and espresso in a saucepan. Stir over low heat until smooth. Add 3/4 cup sugar and corn syrup; increase heat to medium, and stir until the sugar dissolves. Increase heat until the sauce reaches a low boil. Cook without stirring until the mixture thickens, 12 to 15 minutes. Remove espresso fudge sauce from the heat, and cool to room temperature. Pour 1 cup of the sauce over the frozen caramel layer, and return the crust to the freezer. Keep remaining sauce just warm enough so that it remains pourable.
4. Spread the softened ice cream over the caramel layer. Return pie to the freezer until firm, about 1 hour. Pour the remaining fudge sauce over the ice cream layer; freeze until firm, about 2 to 3 hours. Wrap a hot wet towel around the springform pan for about 2 minutes, then remove the sides of the pan.
