How to Make Dark Chocolate Mousse Cake
Follow these simple steps to prepare this delicious Dark Chocolate Mousse Cake:
Step 1: Preheat and Prepare
Preheat your oven to 180°C (350°F). Grease your cake tin with a bit of butter and dust it lightly with flour. This ensures our beautiful cake pops out smoothly when it’s ready.
Step 2: Melt the Chocolate Base
In a heatproof bowl, melt the 60 g of dark chocolate and butter over a pot of simmering water. Stir often until melted and combined. It’s like a warm chocolate hug—just don’t dive in face-first.
Step 3: Mix the Batter
Remove the bowl from heat and stir in caster sugar and hot water. Next, incorporate the plain flour, self-raising flour, and cocoa until just combined. Add the egg and mix vigorously until you have a luscious batter that’s ready for the oven!
Step 4: Bake the Cake
Pour the mixture into your prepared cake tin and smooth the top. Bake for approximately 25 minutes or until a skewer inserted into the center comes out clean. Your house will smell like a chocolate lover’s dream come true.
Step 5: Prepare the Mousse
While the cake is baking, melt the remaining dark chocolates in a bowl over hot water. Keep stirring until smooth. In another bowl, whip the 750 ml of thickened cream until soft peaks form, then gently fold it into the melted chocolate. This is where the magic happens!
Step 6: Assemble and Chill
Once your cake has cooled to room temperature, layer the mousse on top. Pour it over the cooled cake, covering it completely. Refrigerate for at least four hours to let the mousse set. Patience is key here; good things come to those who wait!
