Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Dark Chocolate: Use high-quality chocolate with at least 70% cocoa for the best flavor and richness.
Butter: Unsalted butter works best here; it allows you to control the saltiness of your cake.
Sugar: Granulated sugar adds sweetness; feel free to adjust based on your preference for sweetness.
Eggs: Fresh eggs help create an airy texture, crucial for that light mousse consistency.
Heavy Cream: Whipped cream adds volume and creaminess; make sure it’s well chilled before whipping.
Vanilla Extract: Pure vanilla extract enhances the overall flavor profile of your cake beautifully.
Cocoa Powder: Unsweetened cocoa powder intensifies the chocolate flavor without adding extra sugar.
For the Topping:
Chocolate Shavings: Use a vegetable peeler on your chocolate bar to create beautiful shavings for garnish.
Fresh Berries: Raspberries or strawberries add a pop of color and complement the rich chocolate perfectly.
The full ingredients list, including measurements, is provided in the recipe card directly below.
Let’s Make it together
Preheat your oven to 350°F (175°C). Grease and line an 8-inch round cake pan with parchment paper for easy removal later.
Melt the dark chocolate and butter together in a heatproof bowl over simmering water until smooth. Stir occasionally until fully combined, then remove from heat and let cool slightly.
In another bowl, whisk the sugar and eggs together until pale and fluffy—a good 5 minutes will do the trick here! You want it to resemble soft clouds before slowly folding in the melted chocolate mixture.
In yet another bowl (yes, I know this is getting messy), whip heavy cream with vanilla extract until soft peaks form. Gently fold this into your chocolate-egg mixture—be careful not to deflate all that wonderful air you’ve just whipped up!
Pour half of your batter into the prepared cake pan and bake for about 25-30 minutes, or until a toothpick inserted comes out clean. Let cool completely before removing from the pan.
Once cooled, spread the remaining mousse layer on top and refrigerate for at least two hours (or overnight if you’re feeling patient) to set perfectly!
When you’re ready to serve, garnish with chocolate shavings and fresh berries for that show-stopping finish. Enjoy every delicious bite of your homemade Chocolate Mousse Cake!
