# How To Make It:
01 - Preheat oven to 350°F. Line an 8-inch springform pan with parchment paper and set aside.
02 - In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, granulated sugar, and salt until evenly combined.
03 - In a separate bowl, whisk the eggs, melted unsalted butter, and vanilla extract until smooth. Pour the wet mixture into the dry ingredients and fold together just until incorporated. Spread the batter evenly into the prepared springform pan.
04 - 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.
05 - Soften the gelatin sheets in cold water. In a small saucepan, combine the raspberries, granulated sugar, and water. Heat over medium until the berries break down completely. Puree with a blender, then strain through a fine-mesh sieve to remove the seeds.
06 - Gently warm the strained puree and dissolve the softened gelatin into it. Let the mixture cool to room temperature, then pour evenly over the cooled cake base. Refrigerate until set, approximately 1 hour.
07 - Melt the chopped dark chocolate over a double boiler or in the microwave in 20-second intervals, stirring between each. Let cool slightly until lukewarm.
08 - Beat the egg yolks with 2 tbsp of the granulated sugar and vanilla extract until pale and creamy. Fold in the melted chocolate until fully incorporated.
09 - In a spotlessly clean bowl, whip the egg whites with a pinch of salt until soft peaks form. Gradually add the remaining 2 tbsp of granulated sugar and continue beating until stiff, glossy peaks hold.
10 - In a separate chilled bowl, whip the cold heavy cream to soft peaks using an electric mixer or whisk.
11 - Gently fold the whipped cream into the chocolate mixture in two additions. Then delicately fold in the whipped egg whites until the mousse is smooth, light, and no white streaks remain.
12 - Pour the chocolate mousse over the set raspberry layer and smooth the top with an offset spatula. Cover tightly and refrigerate for at least 4 hours, or until the mousse is fully set.
13 - Release the cake from the springform pan. Arrange fresh raspberries and chocolate curls on top. Dust with powdered sugar if desired. Slice with a warm knife and serve chilled.
# Helpful Hints:
01 -
- The tart raspberry layer cuts through the richness of the mousse in a way that makes it impossible to stop at one slice.
- It looks like it came from a Parisian patisserie but the components are surprisingly manageable if you take them one at a time.
02 -
- Do not even think about skipping the chilling time between the raspberry layer and the mousse, because a warm raspberry layer will melt into the mousse and you will lose those beautiful distinct layers.
- The gelatin must be fully dissolved into warm puree before cooling, because undissolved lumps will create unpleasant chewy bits in your otherwise silky raspberry layer.
03 -
- Fold the egg whites in two additions rather than all at once, because the first addition lightens the chocolate mixture and the second preserves maximum air for a taller fluffier mousse.
- Strain the raspberry puree twice if you want an impossibly smooth layer, because those tiny seeds have a way of sneaking through on the first pass.
