Ingredients
- For the Chocolate Cake:
- 1 cup all-purpose flour
- 1/2 cup cocoa powder
- 1 cup sugar
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1/2 cup milk
- 1/2 cup vegetable oil
- 2 large eggs
- 1 tsp vanilla extract
- 1/2 cup boiling water
- For the Chocolate Mousse:
- 1 1/2 cups heavy cream
- 200g dark chocolate, chopped
- 3 tbsp sugar
- 1 tsp vanilla extract
- 1 tbsp instant coffee (optional, for deepening chocolate flavor)

Preparation Steps
- Make the chocolate cake: Preheat the oven to 350°F (175°C). Grease and flour an 8-inch round cake pan. In a bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt. Add the milk, vegetable oil, eggs, and vanilla, then mix until smooth. Slowly pour in the boiling water and stir until combined (the batter will be thin).
- Bake the cake: Pour the batter into the prepared pan and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let the cake cool in the pan for 10 minutes, then remove it and transfer to a wire rack to cool completely.
- Prepare the mousse: While the cake cools, heat the heavy cream in a small saucepan over medium heat until it begins to simmer. Pour the hot cream over the chopped chocolate in a separate bowl. Let it sit for 1-2 minutes, then stir until smooth. Add the sugar, vanilla, and instant coffee (if using), and mix until fully incorporated. Allow the mousse to cool at room temperature for about 30 minutes, then refrigerate for 1 hour to firm up.
- Assemble the cake: Once the cake has cooled, place it on a serving plate. Spread the chocolate mousse evenly over the top, covering it completely. Refrigerate the cake for at least 2 hours or overnight for best results.
- Serve and enjoy: When ready to serve, you can decorate the top with chocolate shavings, whipped cream, or berries. Slice and enjoy this indulgent chocolate mousse cake!
