Instructions
Crust
To make the crust, crush biscotti to fine crumbs in a food processor. Combine 2 cups of crumbs with the melted butter and stir to combine. Press into a greased 9” pie plate. Bake at 350 for 12 minutes. Cool at room temperature.
Espresso Ganache
To make the espresso ganache heat the heavy cream and espresso powder over medium-low heat until it starts simmering. Put the chocolate chips and butter in a bowl and pour cream over top. Allow to sit for a couple minutes to melt and then whisk until smooth. Reserve about 1/4 cup of ganache for topping the pie. Pour the rest into the crust. Refrigerate until set.
Caramel
To make the caramel, melt the butter and brown sugar together in a small saucepan. Cook over medium heat until it begins to boil. Continue cooking for another 2-3 minutes, stirring continuously. Remove from heat and slowly add heavy cream, whisking until smooth. Whisk in the vanilla. Allow to cool. Set aside about 6 tbsp to use later in the recipe and pour the remaining caramel over the chocolate ganache layer of the pie. Refrigerate until set.
Coffee Mousse
To make the caramel mousse beat together the mascarpone, coffee extract, powdered sugar and vanilla extract until smooth. In a separate mixing bowl, whip 1 1/2 cups of the heavy cream until it forms stiff peaks. Fold the whipped cream into the mascarpone mixture. Spread the mouse over the caramel mixture in the crust. Using a piping bag, a small ziplock bag with the corner cut, or even just a spoon drizzle the remaining ganache and 2 tbsp of the reserved caramel over the pie. Refrigerate to set.
Caramel Whipped Topping
Whip the remaining 1 cup of heavy cream to soft peaks. Add the remaining 1/4 cup of caramel and beat to stiff peaks. Pile on top of the pie or pipe a border around the pie. Garnish with any extra biscotti crumbs. Refrigerate at least 4 hours before serving.
