# Directions:
01 - Preheat oven to 350°F. Line an 8-inch springform pan with parchment paper and set aside.
02 - In a mixing bowl, whisk together the flour, cocoa powder, baking powder, sugar, and salt. In a separate bowl, whisk the eggs, melted butter, and vanilla extract until combined. Pour the wet ingredients into the dry ingredients and stir just until incorporated. Spread the batter evenly into the prepared springform pan.
03 - Bake for 20 to 25 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely in the pan.
04 - Soften the gelatin sheets in cold water. In a saucepan, combine the raspberries, sugar, and water over medium heat. Cook until the berries break down completely. Puree the mixture with a blender, then strain through a sieve to remove the seeds. Gently warm the strained puree and dissolve the softened gelatin into it. Let the puree cool to room temperature, then pour it evenly over the cooled cake base. Refrigerate for about 1 hour, or until firmly set.
05 - Melt the chopped dark chocolate over a double boiler or in the microwave in short intervals, stirring between each. Allow the melted chocolate to cool slightly.
06 - Beat the egg yolks with half the sugar (about 25 g) and the vanilla extract until the mixture turns pale and creamy. Fold in the melted chocolate until fully incorporated.
07 - In a clean, grease-free bowl, whip the egg whites with a pinch of salt until soft peaks form. Gradually add the remaining sugar while continuing to beat until stiff, glossy peaks are achieved.
08 - In a separate chilled bowl, whip the cold heavy cream to soft peaks.
09 - Gently fold the whipped cream into the chocolate-egg yolk mixture. Then delicately fold in the whipped egg whites in two additions, preserving as much volume as possible, until the mousse is smooth and light.
10 - Pour the chocolate mousse over the set raspberry layer and smooth the top with a spatula. Cover the pan and refrigerate for at least 4 hours, or until the mousse is fully set.
11 - Release the cake from the springform pan. Arrange fresh raspberries and chocolate curls on top. Dust lightly with powdered sugar if desired. Slice and serve chilled.
# Expert Tips:
01 -
- The raspberry layer cuts right through the richness of the mousse in a way that surprises people every single time.
- It looks staggeringly impressive but the components are each straightforward on their own.
02 -
- The mousse will collapse if your egg whites or cream have even a trace of yolk or water in the bowl, so wash and dry everything thoroughly first.
- Straining the raspberry puree feels tedious but leaving seeds in changes the entire texture of that middle layer from elegant to rustic.
03 -
- Fold the egg whites in three additions rather than all at once, starting with a vigorous stir to lighten the chocolate mixture and finishing with the gentlest folds you can manage.
- The chocolate you choose defines the entire dessert, so taste it plain first and if it makes you close your eyes, it is the right one.
