Chocolate Mousse Pie

This amazing pie will cure anything and everything. It is so rich, chocolaty and mouth watering good. You absolutely must try it!

Ingredients
20 chocolate sandwich cookies (such as Oreos)
1/4 cup butter cut into pieces, room temperature
12 oz high quality semisweet dark chocolate, finely chopped
1 tsp vanilla extract
Pinch of salt
3-3/4 cups chilled whipping cream
1/4 cup sugar
Chocolate shavings for garnish
Directions
Butter 9" spring-form pan. In a food processor grind the cookies until fine. Add the butter and pulse until combined. Press crumb mixture onto bottom and up sides of prepared pan to form thin crust. Bake crust 5 minutes. Remove from oven and allow to cool completely.
For Mousse: In the bowl of a food processor, combine the chocolate, vanilla and salt. Bring 1 cup cream to boil in heavy small saucepan. With food processor running, gradually pour hot cream in and process until chocolate is melted and smooth. Transfer mixture to large bowl. Cool to room temperature, stirring occasionally.
In the bowl of a standing mixer beat 2 cups cream and sugar until stiff peaks. Fold into chocolate mixture. Pour mousse into prepared crust. Chill until set, about 6 hours. (Can be prepared 1 day ahead.) Beat remaining 3/4 cup cream in medium bowl to firm peaks. Serve sliced pie with whipped cream and chocolate shavings for garnish.
