  • 1 teaspoon instant espresso optional to intensify the chocolate flavor
  • 65 g whole milk heated until hot and lightly foamy
  • 75 g vegetable oil use a neutral-flavored oil
  • 100 g granulated sugar for sweetness and moisture
  • 1 large egg brought to room temperature
  • 90 g sour cream room temperature for a smooth batter
  • 80 g all-purpose flour measured by weight for accuracy
  • 1 teaspoon baking powder fresh baking powder for reliable rising
  • ¼ teaspoon salt balances the sweetness and chocolate
French Silk Pie
  • 2 large eggs for the cooked chocolate filling
  • 125 g granulated sugar creates sweetness and structure
  • 113 g semi-sweet chocolate baking bar finely chopped for quick melting
  • 85 g unsalted butter softened to room temperature
  • ¼ teaspoon salt balances the rich chocolate mixture
  • 110 g heavy whipping cream whipped until stiff peaks form
Whipped Cream
  • 170 g heavy whipping cream well chilled for easier whipping
  • 1 tablespoon granulated sugar for lightly sweetening the topping
  • 1 teaspoon vanilla extract adds warm vanilla flavor
  • ⅛ teaspoon salt enhances the overall flavor

Method
 

  1. Preheat the oven to 350°F (175°C), butter a 7-inch springform pan, and coat the inside with a light layer of sugar.
  2. Combine the cocoa powder and instant espresso in a medium mixing bowl.
  3. Heat the milk in a large microwave-safe bowl or measuring cup until very hot and beginning to foam, leaving plenty of room to prevent overflow.
  4. Immediately pour the hot milk over the cocoa mixture and stir until smooth and lump-free.
  5. Add the oil, sugar, egg, and sour cream, then whisk vigorously until the mixture is evenly combined.
  6. Add the flour, baking powder, and salt, folding gently just until no visible streaks of flour remain.
  7. Pour the batter into the prepared springform pan and bake for 30–35 minutes, until the center is set and an instant-read thermometer inserted into the middle registers about 205°F (96°C).
  8. Let the cake cool in the pan for at least 15 minutes, then transfer it to a cooling rack; prepare the French silk filling while the cake continues cooling.
  9. Finely chop the semi-sweet chocolate and keep it ready for the warm egg mixture.
  10. Whisk the eggs and sugar together in a medium saucepan over medium heat, stirring vigorously until the mixture reaches 170°F (76°C).
  11. Take the saucepan off the heat and immediately stir in the chopped chocolate until completely melted and smooth, then allow the mixture to cool for at least 20 minutes.
  12. Beat the heavy whipping cream in a medium bowl with a hand or stand mixer until stiff peaks form, then refrigerate it until needed.
  13. Beat the softened butter and salt with a mixer for 3–4 minutes, until pale and fluffy.
  14. With the mixer running, gradually add generous spoonfuls of the cooled chocolate mixture, allowing each addition to blend in before adding more; beat the completed mixture for another 2–3 minutes until fluffy.
  15. Gently fold the chilled whipped cream into the chocolate mixture until evenly incorporated without deflating it.
  16. Once the cake has reached room temperature, carefully trim a thin layer from the top to create an even surface.
  17. Line the springform pan with plastic wrap or parchment, return the cake to the pan, and spread the French silk filling evenly over the top.
  18. Cover the cake and refrigerate it for at least 2 hours so the chocolate layer can firm up completely.
  19. Combine the chilled heavy cream, sugar, vanilla, and salt in a medium mixing bowl or stand mixer bowl, then whip until soft peaks form.
  20. Release the chilled cake from the springform pan, spread the whipped cream over the top, garnish with chocolate curls if desired, then slice and serve.
