For the Chocolate Cake Layers
- 1 cup all-purpose flour
- 1 cup granulated sugar
- ½ cup unsweetened cocoa powder
- 1 tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- ½ cup buttermilk (or milk + 1 tsp vinegar)
- ½ cup vegetable oil
- 2 large eggs
- 1 tsp vanilla extract
- ½ cup hot water or hot coffee
For the Chocolate Mousse Layer
- 200g dark chocolate, chopped
- 2 tbsp butter
- 2 cups heavy cream, chilled
- 2 tbsp powdered sugar
For the Vanilla Cream Layer
- 1 ½ cups heavy cream
- 2 tbsp powdered sugar
- 1 tsp vanilla extract
For the Ganache Topping
- 150g dark chocolate
- ¾ cup heavy cream
For Decoration
- Whipped cream rosettes
- Chocolate shavings
- Fresh mint leaves (optional)
- Bake the Cake Layers – Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans. In a large bowl, whisk flour, sugar, cocoa powder, baking powder, baking soda, and salt. Add buttermilk, oil, eggs, and vanilla. Mix until smooth. Stir in hot water/coffee until the batter is thin. Divide into pans and bake 25–30 minutes, or until a toothpick comes out clean. Cool completely, then slice layers horizontally if you want thinner cake layers.
- Make the Chocolate Mousse – Melt chocolate and butter together, let cool slightly. Whip heavy cream with powdered sugar until soft peaks form. Gently fold in melted chocolate mixture until fluffy. Chill until firm.
- Make the Vanilla Cream Layer – Whip heavy cream, sugar, and vanilla until stiff peaks form. Keep chilled.
- Assemble the Cake – Place one chocolate cake layer at the bottom. Spread chocolate mousse evenly. Add another cake layer. Spread vanilla cream. Top with the final cake layer.
- Add the Ganache – Heat cream until just simmering. Pour over chopped chocolate. Let sit 2 minutes, then stir until glossy. Pour over cake, letting it drip down the sides.
- Decorate – Pipe whipped cream rosettes on top. Sprinkle chocolate shavings. Garnish with mint leaves.
Notes
- Chill for at least 2–3 hours before slicing for clean, sharp layers.
- Serve cold with a hot cup of coffee or espresso ☕.
