How to Make It
Make the crust In a food processor, pulse the cookies until finely ground. Transfer to a medium bowl and add the butter and sugar. Mix until well combined, then press into a 9-inch metal pie plate. Refrigerate for 30 minutes.
Preheat the oven to 350°. Bake the crust for 8 to 10 minutes, until set. Transfer to a rack and let cool.
Make the filling In a large bowl, whisk the pumpkin puree with all of the remaining ingredients until smooth. Scrape the filling into the piecrust and bake for 50 minutes to 1 hour, until the filling is set but slightly jiggly in the center. Transfer to a rack and let cool completely.
Make the topping In a medium bowl, using a hand mixer, beat the crème fraîche with the cream and confectioners’ sugar until soft peaks form. Spoon the topping over the pie, garnish with chocolate curls and serve.
To make chocolate curls, use a vegetable peeler to shave them right off of a large block of chocolate.
