Ingredients
- All-purpose flour – 1 cup (125 g / 4.4 oz)
- Cocoa powder, unsweetened – ¼ cup (25 g / 0.9 oz)
- Baking powder – 1 tsp
- Granulated sugar – ¾ cup (150 g / 5.3 oz)
- Large eggs – 2, room temperature
- Unsalted butter – ½ cup (115 g / 4 oz), melted and slightly cooled
- Vanilla extract – 1 tsp
- Whole milk – ½ cup (120 ml / 4 fl oz)
- Dark chocolate (70% cocoa or higher) – 8 oz (225 g), chopped
- Heavy cream – 1 ½ cups (360 ml / 12 fl oz), chilled
- Granulated sugar – 2 tbsp
- Vanilla extract – ½ tsp
- Fresh raspberries – 1 cup (about 125 g / 4.4 oz)
- Powdered sugar – 1 tbsp (optional)
- Lemon juice – 1 tsp
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour an 8-inch (20 cm) round cake pan or line it with parchment paper.
- In a medium bowl, sift together the all-purpose flour, cocoa powder, and baking powder. Set aside.
- In a separate large bowl, beat the eggs and granulated sugar until pale and fluffy (3-4 minutes with an electric mixer). Add melted butter, vanilla extract, and milk, mixing until combined.
- Gradually fold the dry ingredients into the wet mixture using a spatula. Pour the batter into the prepared pan and smooth the top.
- Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let cool completely in the pan on a wire rack.
- Melt the chopped dark chocolate in a double boiler or microwave in 30-second bursts, stirring in between. Let cool slightly but do not harden.
- In a chilled bowl, whip the heavy cream with sugar and vanilla until soft peaks form.
- Gently fold the melted chocolate into the whipped cream in three additions, folding carefully to keep it airy and smooth.
- Spread the mousse evenly over the cooled cake base. Chill in the refrigerator for at least 2 hours, preferably overnight.
- Toss raspberries with lemon juice and powdered sugar (if using). Let sit for 10 minutes to macerate.
- Spoon the raspberry topping over the set mousse just before serving.
Notes
Use good-quality dark chocolate (70% cocoa or higher) for best mousse texture. Fully cool the cake before adding mousse to prevent melting. Whip cream to soft peaks and fold chocolate gently to keep mousse airy. Lemon juice in raspberry topping adds a bright zing. Chilling assembled cake overnight improves flavor and texture. For quicker setting, chill in freezer for 30 minutes then return to fridge before serving.
