Chocolate Cake
- 115 g all-purpose flour
- 40 g natural cocoa powder
- ½ teaspoon baking powder
- ¼ teaspoon baking soda
- ¼ teaspoon salt
- 1 large egg, room temperature
- 50 g granulated sugar
- 50 g brown sugar
- 110 g light-tasting oil (such as canola or vegetable oil)
- 200 g milk, room temperature
Chocolate Mousse
- 400 g whipping cream or heavy cream, divided into 200 g + 200 g
- 200 g dark or semi-sweet chocolate, finely chopped
Chocolate Ganache Topping
- 180 g whipping cream or heavy cream
- 170 g dark chocolate, finely chopped
Filling & Topping
- 10 fresh strawberries, halved, plus more for topping
- Prepare the Chocolate Cake: Preheat your oven to 350°F (175°C) and prepare a 9″ springform pan. In a small bowl, combine the flour, cocoa powder, baking powder, baking soda, and salt. Set aside. In a larger bowl, whisk together the egg, granulated sugar, and brown sugar until well combined. Add the oil and whisk again until smooth.
- Mix Batter: Add half the dry ingredient mixture to the egg mixture, mixing until just combined. Then add half the milk, mixing again. Repeat with remaining flour mixture and milk until the batter is thick but fluid.
- Bake the Cake: Pour the batter into the springform pan. Optionally, add cake strips around the pan to prevent doming. Bake for 30-32 minutes or until a toothpick inserted comes out mostly clean. Cool completely in the pan on a wire rack.
- Level the Cake (if needed): If the cake has risen unevenly, carefully level it with a serrated knife to create a flat layer. Return the cake to the pan and reassemble the sides.
- Prepare the Chocolate Mousse: Place the chopped chocolate in a heat-safe bowl. Heat 200 g whipping cream on medium heat until simmering (tiny bubbles). Pour hot cream over the chocolate and let sit for 5 minutes, then gently stir until smooth. Warm gently if needed. Allow to cool while whipping the remaining 200 g cream to soft peaks with a mixer or whisk.
- Combine Mousse Ingredients: Fold one-third of the whipped cream into the chocolate ganache to lighten it, then fold this mixture into the remaining whipped cream gently until uniform and streak-free.
- Assemble Mousse Layer: Arrange halved strawberries around the perimeter of the cake pressing cut edges to the pan. Spread the mousse mixture evenly over the cake layer, filling the gaps between strawberries, smoothing the top.
- Chill Mousse Layer: Cover and refrigerate for at least 4 hours or overnight to allow the mousse to set properly.
- Prepare Chocolate Ganache Topping: Place chopped chocolate in a heat-safe bowl. Heat 180 g whipping cream until simmering. Pour over chocolate and let sit for 5 minutes, then stir until smooth and glossy. Warm gently if needed and let cool slightly to thicken.
- Apply Ganache: Pour ganache over the chilled mousse layer. Use an offset spatula to spread to edges and smooth the top. Chill for another 30 minutes to set the ganache.
- Decorate and Serve: Decorate the top with additional fresh strawberries. For clean slices, run your knife under hot water, wipe dry, and cut between servings. Serve chilled.
Notes
- Ensure all ingredients, especially eggs and milk, are brought to room temperature for best mixing results.
- Use good quality dark chocolate (60-70% cocoa) for a rich mousse and ganache.
- You can line the springform pan with parchment paper if preferred, but it’s optional.
- Adjust sugar quantity slightly depending on the sweetness of the chocolate used.
- Chilling times are important to achieve a nicely set mousse and ganache layers.
- For a vegan or dairy-free version, substitute cream with coconut cream and use dairy-free chocolate, but texture and flavor may vary.
