Ingredients You Need
- 200 grams of high-quality dark chocolate with at least 70 percent cocoa for a deep, bittersweet base. Opt for good-quality chocolate as it truly shapes the flavor
- 100 grams of unsalted butter at room temperature melts smoothly into the chocolate to add silkiness
- Four large eggs separated carefully so the yolks and whites can do their magic in separate steps
- 150 grams of granulated sugar to sweeten the mousse just right without overpowering the dark chocolate
- 250 milliliters of heavy cream whipped to soft peaks contributes lightness and creates the mousse’s airy lift
- Two teaspoons of vanilla extract to round out the chocolate's richness with a subtle floral note
Detailed Cooking Directions
- Build The Chocolate Base:
- Melt the dark chocolate gently over simmering water until perfectly smooth and glossy. Remove from heat and stir in the room temperature butter until fully combined and silky.
- Whisk Egg Yolks and Sugar:
- In another bowl, whisk the egg yolks with the sugar until the mixture becomes pale and fluffy, creating a light, sweet foundation.
- Combine Chocolate and Yolks:
- Slowly add the melted chocolate mixture into the whisked egg yolks, stirring until the blend is smooth and even.
- Whip Egg Whites:
- In a completely clean bowl, whisk the egg whites until stiff peaks form, which is key for that delicate mousse texture.
- Fold Whites Into Chocolate Mixture:
- Gently fold the whipped egg whites into the chocolate and yolk blend, careful not to deflate the mixture so it stays light and airy.
- Set and Chill:
- Pour the mousse into a lined springform pan. Refrigerate for at least four hours or overnight to let it set to the perfect firmness.
- Serve And Enjoy:
- Once cooled and set, remove carefully from the pan and slice into generous portions to delight any chocolate lover.
My favorite part is folding the egg whites in gently and watching the mousse come alive with such luxurious fluffiness. I remember the first time I served this to guests, their delighted expressions confirmed it as a decadent success.
Smart Storage Tips
Store the cake covered in the refrigerator to keep the mousse fresh and creamy for up to three days
If you want to freeze the cake, wrap tightly in plastic wrap and foil, thaw in the fridge overnight before serving
Avoid storing at room temperature as the mousse softens and loses structure quickly
Ingredient Variations
Try swapping half the dark chocolate for milk chocolate to soften the intensity for a sweeter palate
Add a splash of espresso or coffee extract to the melted chocolate for a mocha undertone
Incorporate a handful of finely chopped toasted hazelnuts into the mousse for added texture and nutty complexity
Perfect Pairing Ideas
Serve alongside fresh raspberries or a mixed berry compote to cut through the richness
A dollop of lightly sweetened whipped cream adds an extra cloud of softness
Pair with a rich port wine or a bold espresso to complement the chocolate depth
If you want to serve the cake with a clean cut, dip your knife in hot water and wipe it between slices for perfect presentation every time.
Frequently Asked Questions
- → What type of chocolate works best for this mousse?
High-percentage dark chocolate, around 70% cocoa, is ideal to balance richness and bitterness for a deep chocolate flavor.
- → How do I achieve stiff peaks when whipping egg whites?
Use a clean, dry bowl and whisk on medium-high speed until glossy peaks hold firmly without drooping.

Chilling allows the mousse to firm up and develop a smooth, creamy texture that holds its shape when sliced.
- → Can I substitute whipped cream with another ingredient?
Whipped cream adds lightness and richness, but alternatives like mascarpone can be used for a denser texture.
- → What tips help prevent the mousse from deflating?
Fold the egg whites gently into the chocolate mixture to keep the airy structure intact, avoiding overmixing.
