Instructions
1️⃣ Make the Cupcakes
- Preheat oven to 350°F (175°C). Line a muffin pan with cupcake liners.
- In a bowl, whisk flour, cocoa powder, baking soda, and salt.
- In another bowl, whisk granulated sugar, brown sugar, oil, egg, and vanilla. Add buttermilk and mix until smooth. Stir in dry ingredients, then slowly whisk in hot coffee or water until batter is smooth and thin.
- Fill liners ⅔ full. Bake 18–20 minutes, until a toothpick inserted comes out with a few moist crumbs. Cool completely.
2️⃣ Make the French Silk Filling
- Heat cream until just steaming (not boiling). Pour over chopped chocolate and let sit 1 minute, then stir until smooth. Let cool to room temperature.
- In a bowl, beat butter and powdered sugar until light and fluffy (2–3 minutes). Beat in vanilla and salt. Slowly add cooled chocolate mixture and whip until smooth, fluffy, and mousse-like.
- Chill 20–30 minutes to firm slightly.
3️⃣ Fill the Cupcakes
- Core the center of each cupcake. Spoon or pipe French silk filling into each cavity.
4️⃣ Whipped Cream Topping
- Beat heavy cream, powdered sugar, and vanilla until soft peaks form. Pipe or spoon onto filled cupcakes.
5️⃣ Garnish & Serve
- Top with chocolate curls, shavings, or cocoa powder if desired.
Notes
- Silk filling texture: The chocolate mixture should be completely cooled before whipping into the butter. If it’s warm, the filling can turn loose or greasy instead of silky.
- Butter temperature matters: Use softened butter, not melted. Properly creamed butter gives the filling its light, mousse-like texture.
- Cupcake coring: Remove only the center inch of each cupcake so the structure stays sturdy once filled.
- Whipped cream stability: For longer holding time, add 1 teaspoon cornstarch or instant pudding mix to the whipped cream while whipping.
- Chocolate choice: Semi-sweet gives classic French silk flavor. Bittersweet creates a darker, less sweet result.
- Make-ahead: Cupcakes and filling can be made up to 24 hours ahead and stored separately. Assemble with whipped cream just before serving for the freshest look.
- Serving temperature: These cupcakes are best served slightly chilled, but allow them to sit at room temperature for 10 minutes before eating for the silkiest texture.
- Storage: Store assembled cupcakes covered in the refrigerator for up to 3 days.
- Freezing: Freeze unfilled cupcakes only. The silk filling and whipped cream do not freeze well.
