Ingredients:

  • 1 ¼ cups All-Purpose Flour
  • 1 teaspoon Granulated Sugar (for crust)
  • ½ teaspoon Salt (for crust)
  • ½ cup Unsalted Butter (very cold, cubed)
  • 3–5 tablespoons Ice Water
  • 8 ounces Bittersweet or Semisweet Chocolate (high quality, chopped)
  • ½ cup Unsalted Butter (softened)
  • 1 cup Granulated Sugar (for filling)
  • 3 Large Eggs (separated)
  • 1 teaspoon Vanilla Extract
  • 2 tablespoons Strong Brewed Coffee (cooled)
  • Pinch of Salt (for whites)
  • 1 ½ cups Heavy Whipping Cream (very cold)
  • 3 tablespoons Powdered Sugar (sifted, for topping)
  • ½ teaspoon Vanilla Extract (for topping)

Instructions:

  1. Prepare the Crust: Combine flour, 1 tsp sugar, and ½ tsp salt. Cut in the cold butter until pea-sized crumbs form. Slowly add ice water until the dough just comes together. Form into a disk, wrap, and chill for at least 30 minutes.
  2. Roll and Blind Bake: Roll the dough out and fit into the 9-inch pie plate. Crimp edges and chill again for 15 minutes. Prick the bottom well. Line with parchment and pie weights. Blind bake at 375°F (190°C) for 15 minutes. Remove weights/parchment and bake an additional 3–5 minutes until lightly golden. Cool completely.
  3. Melt the Chocolate: Gently melt the chopped chocolate over a double boiler until smooth. Set aside to cool slightly.
  4. Create the Base Cream (Yolks): In a large bowl, cream the softened butter and 1 cup sugar until fluffy. Beat in the egg yolks one at a time. Stir in cooled coffee and 1 tsp vanilla. Slowly incorporate the slightly cooled melted chocolate until fully combined.
  5. Temper and Whip Egg Whites: In a separate, clean bowl, whip the egg whites with a pinch of salt until stiff peaks form. (For extra safety, gently heat the whites over the double boiler to 160°F/71°C while whisking before whipping them to stiff peaks).
  6. Lighten the Filling: Gently fold one-third of the stiff egg whites into the chocolate base to lighten it, then fold in the remaining whites until no streaks remain. Be gentle to preserve the air.
  7. Assemble and Chill: Pour the lightened filling into the cooled crust. Smooth the top. Cover loosely and refrigerate for a minimum of 4 hours, or ideally overnight, until completely firm.
  8. Make the Topping: Just before serving, whip the heavy cream, powdered sugar, and ½ tsp vanilla until stiff peaks form.
  9. Serve: Spread or pipe the whipped cream over the chilled pie. Garnish with chocolate shavings or cocoa powder. Slice and serve immediately.
