A classic Chocolate French Silk Pie with a silky chocolate mousse filling in an all-butter pie crust, finished with vanilla chantilly whipped cream and chocolate shavings. The rich, smooth texture—made from eggs, sugar, dark chocolate and whipped cream—earns an enthusiastic “oh la la” from anyone who tastes it. Elegant enough for a pastry shop but deceptively simple to make at home.

A Chocolate Mousse Pie
French silk pie is an American creation inspired by classic French mousse au chocolat. The filling is made by tempering eggs with sugar to create a safe, custardy base, folding in melted chocolate, then incorporating whipped cream for a light, airy mousse. The only baking step is blind-baking the crust; after that it’s assembly and chilling until set.
Key Ingredients & Notes
- All-butter pie crust: Use a flaky, homemade all-butter crust for the best flavor and texture. A store-bought 9-inch crust works in a pinch.
- Bittersweet dark chocolate (60–70% cocoa): Offers the best balance of deep chocolate flavor and smooth texture. Avoid chocolate chips; use a high-quality baking bar.
- Heavy whipping cream (33–36% fat): Whipped into the filling and again for the topping to provide richness and structure.
- Mascarpone: Helps stabilize the chantilly cream topping and adds a subtle tang that balances the chocolate.

How to Make a French Silk Pie
I often split this recipe across two days: day one for making and blind-baking the crust, day two for the filling and chilling. Whip the chantilly cream just before serving for the freshest texture.

- Blind bake a 9-inch all-butter pie crust until golden; cool completely.

- Whisk eggs and sugar in a saucepan over medium-low heat until the mixture reaches 160°F (72°C) to ensure safety and a custard-like base.

- Melt bittersweet dark chocolate until smooth, then let it cool slightly.

- Whisk the cooked egg-and-sugar mixture into the melted chocolate until shiny and smooth.

- Whip heavy cream with powdered sugar and vanilla to soft-to-stiff peaks; chill until ready to fold into chocolate.

- Beat softened unsalted butter until smooth and slightly fluffy.

- Pour the cooled chocolate-egg mixture into the whipped butter and beat until thick, smooth and glossy.

- The chocolate-butter mixture should be smooth and at room temperature before folding in the whipped cream.

- Spoon one-third of the whipped cream into the chocolate mixture to lighten it, then fold gently.

- Fold the remaining whipped cream in two more additions, using a spatula and gentle motions to keep the mixture airy.

- Transfer the chocolate mousse into the cooled pie shell, smoothing the surface with an offset spatula.

- Chill the pie in the refrigerator for at least 2 hours, or overnight, until the filling is set.

- Make a stabilized chantilly cream with mascarpone, powdered sugar and vanilla, then spread it over the chilled chocolate filling just before serving.

- Use a vegetable peeler to shave a chocolate bar over the whipped cream to make delicate curls for garnish.
Jenn’s Pie Tips
- Pan choice: Metal pans conduct heat best for blind-baking; add a few extra minutes if using ceramic.
- Blind bake ahead: You can bake the crust up to 2 days in advance and store it airtight at room temperature.
- Check the temperature: Use an instant-read thermometer to ensure the egg-sugar mixture reaches 160°F (72°C).
- Top last: Make the chantilly cream topping right before serving so it stays light and fresh.
- Variations: Finish with cocoa dusting, chopped nuts or fresh berries for color and texture.
- Make-ahead: The assembled pie (without whipped topping) can be refrigerated up to 2 days; top just before serving.
