👩‍🍳 Instructions

Step 1: Bake the Chocolate Sponge

1. Preheat oven to 180°C (350°F). Grease and line a 7-inch round cake pan.

2. In a bowl, mix flour, cocoa powder, baking soda, baking powder, and salt.

3. In another bowl, whisk together sugar, eggs, oil, and vanilla until creamy.

4. Add dry ingredients alternately with buttermilk, then mix in hot water slowly until smooth.

5. Pour into the prepared pan and bake for 25–30 minutes or until a toothpick comes out clean.

6. Let it cool completely before adding the mousse.

Step 2: Prepare the Dark Chocolate Mousse

1. Melt the chopped dark chocolate in a double boiler or microwave (30-second intervals). Let it cool slightly.

2. If using gelatin, dissolve it in warm water and mix into the melted chocolate.

3. In another bowl, beat egg whites until soft peaks form. Add sugar gradually and continue to beat until glossy.

4. Gently fold the egg yolks into the chocolate mixture, then fold in the whipped cream and egg whites carefully to keep it light and airy.

Step 3: Assemble the Cake

1. Place the cooled cake base in a springform pan or cake ring.

2. Pour the chocolate mousse evenly over the top.

3. Smooth the surface and refrigerate for 4–6 hours (or overnight) to set completely.

Step 4: Make the Ganache

1. Heat the cream in a saucepan until just simmering.

2. Pour it over the chopped chocolate and let it sit for a minute.

3. Stir until smooth and glossy, then mix in the butter.

4. Let it cool slightly before pouring over the chilled mousse cake.

Step 5: Decorate and Serve
