# Steps:
01 - Preheat oven to 350°F. Line an 8-inch springform pan with parchment paper, pressing it flat against the base.
02 - In a medium bowl, sift together the flour, cocoa powder, baking powder, sugar, and salt until evenly blended.
03 - In a separate bowl, whisk the eggs, melted butter, and vanilla extract until smooth and well incorporated.
04 - Pour the wet mixture into the dry ingredients and fold together gently just until combined — do not overmix. Spread the batter evenly across the bottom of the prepared springform pan.
05 - Bake for 20 to 25 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan on a wire rack.
06 - Soften the gelatin sheets in a bowl of cold water. Meanwhile, combine the raspberries, sugar, and water in a saucepan over medium heat. Cook until the berries break down completely, then puree with a blender and strain through a fine sieve to remove seeds.
07 - Gently warm the strained puree and dissolve the softened gelatin into it. Let the mixture cool to room temperature, then pour it evenly over the cooled cake base. Refrigerate until firm, approximately 1 hour.
08 - Melt the chopped dark chocolate over a double boiler or in short microwave bursts at 50% power, stirring between intervals. Let cool slightly until just warm to the touch.
09 - In a mixing bowl, beat the egg yolks with half the sugar (about 25 g) and the vanilla extract until the mixture turns pale yellow and falls in thick ribbons from the whisk. Stir in the melted chocolate until fully incorporated.
10 - In a spotlessly clean bowl, whip the egg whites with a pinch of salt until soft peaks form. Gradually sprinkle in the remaining sugar and continue beating to stiff, glossy peaks.
11 - In a separate chilled bowl, whip the cold heavy cream to soft peaks — it should hold its shape but still have a smooth, spreadable consistency.
12 - Fold the whipped cream into the chocolate-yolk mixture first. Then gently fold in the whipped egg whites in two additions, using a rubber spatula with light sweeping motions to preserve volume. Pour the mousse over the set raspberry layer and smooth the top with an offset spatula.
13 - Cover the pan with plastic wrap and refrigerate for at least 4 hours, or until the mousse is completely firm and set.
14 - Release the springform ring and transfer the cake to a serving plate. Arrange fresh raspberries, chocolate curls, and a light dusting of confectioners' sugar over the top. Slice with a warm, clean knife for neat portions.
# Expert Tips:
01 -
- The three layers look like they took professional training but the technique is surprisingly forgiving.
- That tangy raspberry middle cuts through the chocolate so nothing feels heavy or cloying.
02 -
- If even a speck of yolk gets into your egg whites they will never whip properly so separate eggs carefully while they are still cold.
- The mousse needs the full four hours minimum to set and slicing it early will cause the layers to slide apart.
03 -
- Fold the egg whites in two batches because trying to mix them all at once leads to overfolding and a dense mousse.
- Strain the raspberry puree twice if you want an impossibly smooth layer that sits perfectly against the mousse.
