6ounces semisweet or bittersweet chocolate, chopped
6 tablespoons butter, cut into pieces
1/2 teaspoon instant coffee powder
3/4cup medium or dark brown sugar
3 large eggs
1/2 teaspoon salt
1 teaspoon vanilla extract
for the whipped cream topping
1cup heavy whipping cream
2 tablespoons powdered sugar
bittersweet chocolate, shaved
Instructions
Preheat oven to 350°F. Grease a large pie pan.
In a standing mixer or food processor, pulse chocolate wafer cookies until only fine crumbs remain.
Pulse in melted butter until everything comes together. Spread crust evenly into pie pan and set aside.
In a small saucepan over low heat, melt the chocolate, butter, and coffee powder. Set aside to cool.
Using an electric mixer, beat the brown sugar, eggs, salt, and vanilla extract on high speed until light and airy, about 4 to 5 minutes. Once the melted chocolate mixture has cooled slightly, slowly pour it into the egg mixture, beating as you pour. Beat an additional minute so that everything really comes together.
Pour batter into prepared crust and bake until puffed and beginning to crack at the edges, 20 to 25 minutes. Cool for 30 minutes, then chill in the fridge until ready to serve.
Beat the heavy cream and powdered sugar until soft peaks form. Spread over the pie and sprinkle with shaved bittersweet chocolate.
