Ingredients
Scale
Chocolate Ganache Base
- 8 oz Dark Chocolate (60-70% cacao, finely chopped, 225g)
- 1/2 cup Heavy Whipping Cream (120ml)
- 1 tbsp Unsweetened Cocoa Powder (7g)
- 1/4 tsp Fine Sea Salt
- 1 tsp Vanilla Extract (5ml)
Whipped Cream
- 1 1/2 cups Heavy Whipping Cream (360ml)
- 1/4 cup Granulated Sugar (50g)
Instructions
- Prepare the Chocolate Ganache: Place the finely chopped dark chocolate in a heatproof bowl. Heat 1/2 cup (120ml) of heavy cream until it just reaches a simmer, then pour it over the chocolate.
- Melt Chocolate: Let the mixture sit for a minute to soften the chocolate, then stir gently until completely smooth and glossy.
- Cool Base: Stir in the unsweetened cocoa powder, fine sea salt, and vanilla extract into the ganache. Let the mixture cool to room temperature, around 85°F (29°C), to set the base without hardening.
- Whip Cream: In a separate chilled bowl, whip the remaining 1 1/2 cups (360ml) of heavy cream and granulated sugar until medium-stiff peaks form. Take care not to overwhip to maintain a smooth texture.
- Temper Mousse: Fold a small portion of the whipped cream into the cooled chocolate ganache mixture to lighten it, ensuring gentle incorporation.
- Final Fold: Carefully fold in the remaining whipped cream using a spatula. Work gently to combine fully without deflating the mousse, keeping the mixture light and airy with no visible white streaks.
Notes
- Use good quality dark chocolate with at least 60% cacao for best flavor and texture.
- Ensure the whipped cream is cold and the bowl chilled to achieve optimal volume and stability.
- Allow the mousse to chill in the refrigerator for at least 1 hour before using it as a cake filling for the best set.
- This mousse can be prepared a day ahead and covered tightly in the fridge.
- If the mousse feels too soft after chilling, gently re-whip or fold in a little more whipped cream.
