NO BAKE CHOCOLATE MOUSSE PIE
1 ounce unsalted butter, melted; more for the pan
8 ounces Italian chocolate wafer sandwich cookies (Quadratini) (if you don't have these you can use Famous Chocolate Wafers or Oreos)
9 ounces semisweet chocolate, chopped (about 1-1/2 cups); more for garnish
1-1/2 tsp vanilla extract
Pinch kosher salt
3-3/4 cups heavy cream
Butter 9-inch springform pan.
Grind cookies in food processor until they resemble wet sand, 20 to 30 seconds; you will have about 1-3/4 cups. Transfer to small bowl and mix in butter. Spread crumbs in pan, cover with plastic wrap, and press evenly into bottom. Refrigerate.
Combine chocolate, 1/2 tsp of vanilla, and salt in large bowl. In small saucepan, bring 3/4 cup of cream to barely a simmer. Pour cream over chocolate, let sit for 1 minute, then whisk until smooth. Cover and refrigerate for about 30 minutes to cool.
Beat 1-1/2 cups of cream in medium bowl with electric mixer on medium-high speed to stiff peaks, about 2 minutes. Whisk chocolate mixture to loosen, and fold into whipped cream with large silicone spatula until no streaks remain.
Carefully peel plastic wrap off crust and scrape mousse into pan, gently spreading to edges. Cover and refrigerate for at least 6 hours.
Just before serving, beat remaining 1-1/2 cups cream and 1 tsp vanilla in medium bowl to medium-stiff peaks. Run knife around pie to loosen edges and then remove side of pan. Slide spatula under crust and transfer pie to serving plate. Mound whipped cream over mousse and top with chocolate curls, shards, or shavings.
To serve, dip knife into hot water and dry before slicing.
