01 - Pulse cookies in a food processor until fine crumbs form. Add melted butter and blend until evenly combined. Press mixture firmly into the bottom and up the sides of a 9-inch pie dish. Refrigerate for 20 minutes to set.
02 - Preheat oven to 350°F. Bake chilled crust for 8–10 minutes until set. Allow to cool completely before filling.
03 - Set up a double boiler with a heatproof bowl over barely simmering water. Add chopped chocolate and stir until completely smooth. Remove from heat and let cool to room temperature.
04 - In a large bowl, beat softened butter and granulated sugar on medium-high speed until pale and fluffy, approximately 3–4 minutes.
05 - Add cooled melted chocolate, vanilla extract, and salt to the butter mixture. Beat until fully incorporated and smooth.
06 - Add eggs one at a time, beating on high speed for 3–5 minutes after each addition. The mixture should become silky and noticeably increased in volume.
07 - Spread filling evenly into the cooled crust. Refrigerate for at least 3 hours or until completely set.
08 - In a chilled bowl, beat heavy cream, powdered sugar, and vanilla extract until soft peaks form.
09 - Mound whipped cream over the chilled pie filling. Garnish with chocolate curls or shavings if desired. Serve chilled.
