# How To Make It:
01 - Preheat oven to 350°F. Grease a 9-inch springform pan and line the base with parchment paper.
02 - Sift together the flour, cocoa powder, baking powder, and salt into a medium bowl. In a separate bowl, whisk the sugar, eggs, vegetable oil, milk, and vanilla extract until smooth. Gradually fold the dry ingredients into the wet mixture, stirring until just combined. Pour the batter into the prepared pan and bake for 20–25 minutes until set. Allow the cake to cool completely in the pan.
03 - Sprinkle the gelatin over cold water and let it soften for 5 minutes. Combine the raspberries, sugar, and lemon juice in a saucepan over medium heat. Mash the berries and simmer for 5–8 minutes. Remove from heat and stir in the softened gelatin until fully dissolved. Let the mixture cool to room temperature.
04 - Melt the dark chocolate over a double boiler or in the microwave until smooth, then let it cool slightly. Beat the egg whites with a pinch of salt to soft peaks, then gradually add sugar while beating to stiff peaks. In a separate bowl, whip the cold heavy cream to soft peaks. Stir the egg yolks into the cooled melted chocolate, gently fold in the whipped cream, then carefully fold in the beaten egg whites.
05 - Spread the cooled raspberry mixture evenly over the cooled cake base still in the springform pan. Chill for 15 minutes until slightly set. Gently spread the chocolate mousse over the raspberry layer and smooth the top. Refrigerate for at least 2 hours or overnight until fully set.
06 - Heat the cream just until steaming and pour it over the chopped chocolate. Let it sit for 2 minutes, then stir until glossy and smooth. Cool slightly, then pour the ganache over the chilled mousse cake. Refrigerate for 30 minutes.
07 - Decorate the top with fresh raspberries and chocolate shavings. Carefully remove the springform ring and slice with a hot knife for clean portions.
# Expert Tips:
01 -
- The three layers look stunning but each one is surprisingly straightforward to pull off.
- That tangy raspberry middle cuts through the richness of the chocolate in a way that keeps everyone reaching for another slice.
02 -
- The mousse relies on raw egg whites, so use pasteurized eggs if that concerns you or if you are serving anyone with a compromised immune system.
- Do not rush the chilling time between layers or the raspberry filling will bleed into the mousse and you will lose those beautiful distinct layers.
03 -
- Fold the egg whites into the mousse in three additions rather than all at once to keep the texture light and cloudlike.
- When making the ganache, resist the urge to stir immediately after pouring the cream over the chocolate and instead let the heat do the work for two full minutes before you touch it.
