Chocolate Lover's Chocolate Mousse Pie

Preheat oven to 350°F (175°C).

Combine graham cracker crumbs, cocoa and granulated sugar in 9-inch pie plate. Stir in butter until all ingredients are moistened; press onto bottom and up sides of pie plate. Bake for 8 to 10 minutes. Sprinkle 1/2 cup morsels over bottom of hot crust; let stand for 10 minutes or until all morsels are shiny. Spread chocolate over bottom and up sides of crust. Cool to room temperature.

Microwave 2 cups morsels and 3/4 cup cream in large, microwave-safe bowl on HIGH (100%) power for 1 minute; stir. Microwave at additional 10 to 20-second intervals, stirring until smooth. Cool to room temperature.

Beat remaining cream, sugar and vanilla extract in chilled small mixer bowl until soft peaks form. Fold 2 cups whipped cream into chocolate mixture. Spoon into crust; swirl top. Garnish with remaining whipped cream. Refrigerate until firm.

Microwave remaining 1/4 cup morsels in heavy-duty plastic bag on HIGH (100%) power for about 30 seconds; knead until smooth. Cut tiny corner from bag; squeeze to drizzle chocolate over pie; let stand a few minutes before serving.
