Ingredients 🛒
- The Foundation:
- 1 thin layer of dark chocolate sponge cake (baked and cooled)
- The Chocolate Mousse:
- 8 oz semi-sweet chocolate, melted
- 2 cups heavy whipping cream, chilled (divided)
- 3 large egg yolks
- 1/4 cup granulated sugar
- Salted Caramel Topping:
- 1 cup granulated sugar
- 6 tbsp unsalted butter, room temperature
- 1/2 cup heavy cream
- 1 tsp sea salt (flaked)
- The Garnish:
- Whipped cream (for rosettes)
- Chocolate curls & caramel chunks
- Chocolate cake crumbs (for the sides)
Step-by-Step Instructions 👩🍳
- Prepare the Base: Place your pre-baked chocolate sponge layer into a parchment-lined springform or loaf pan. Press chocolate crumbs firmly into the sides for texture.
- Whisk the Mousse: Whisk egg yolks and sugar over a double boiler until thickened. Stir in the melted chocolate. In a separate bowl, whip 1 ½ cups of heavy cream to stiff peaks, then gently fold it into the chocolate mixture.
- Layer and Set: Pour the mousse over the sponge base. Smooth the top with an offset spatula. Freeze for 15–20 minutes to create a firm surface for the caramel.
- Craft the Caramel: Melt sugar in a saucepan until golden amber. Stir in butter until melted, then slowly pour in the heavy cream and salt. Let it cool until it is thick but still pourable.
- The Caramel Pour: Pour the salted caramel over the chilled mousse, tilting the pan to ensure it reaches every edge.
- Final Decoration: Refrigerate until fully set (about 4 hours). Before serving, pipe whipped cream rosettes around the border and top with chocolate curls and extra caramel chunks.
Pro-Tips for Success
- Temperature Control: Ensure your caramel is cooled to room temperature before pouring; if it’s too hot, it will melt the mousse layer below.
- Flaked Salt: Use high-quality flaked sea salt for the topping. It provides a better visual and a more intentional “pop” of flavor than standard table salt.
- Clean Slices: For those perfect, defined layers, wipe your knife clean with a warm cloth between every single slice.
