# Cooking steps:

01 - Preheat oven to 350°F. Line an 8-inch springform pan with parchment paper and set aside.
02 - In a medium bowl, whisk together the flour, cocoa powder, baking powder, sugar, and salt until evenly combined.
03 - In a separate bowl, whisk the eggs, melted butter, and vanilla extract until smooth.
04 - Pour the wet mixture into the dry ingredients and fold together just until combined. Do not overmix. Spread the batter evenly into the prepared springform pan.
05 - Bake for 20 to 25 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely in the pan.
06 - Soften the gelatin sheets in cold water. In a saucepan, combine the raspberries, sugar, and water. Heat over medium until the berries break down completely. Blend with an immersion blender, then strain through a fine sieve to remove seeds.
07 - Gently warm the strained puree and dissolve the softened gelatin into it. Let cool to room temperature, then pour evenly over the cooled cake base. Refrigerate until set, about 1 hour.
08 - Melt the chopped dark chocolate over a double boiler or in the microwave in 30-second intervals, stirring between each. Let cool slightly.
09 - Beat the egg yolks with 2 tablespoons of sugar and vanilla extract until pale and thick. Fold in the melted chocolate until fully incorporated.
10 - In a spotless bowl, whip the egg whites with a pinch of salt until soft peaks form. Gradually add the remaining 2 tablespoons of sugar and continue beating until stiff, glossy peaks hold.
11 - In another chilled bowl, whip the cold heavy cream to soft peaks.
12 - Gently fold the whipped cream into the chocolate-yolk mixture. Then delicately fold in the whipped egg whites in two additions, preserving as much air as possible. The mousse should be smooth and light.
13 - 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 completely firm.
14 - Release the cake from the springform pan. Arrange fresh raspberries and chocolate curls on top. Dust lightly with powdered sugar if desired. Slice with a warm knife for clean portions.

# Tips from flavorandfeast:

01 -
  • The contrast between intense dark chocolate and bright raspberry creates something genuinely sophisticated
  • Despite its fancy appearance, each component is straightforward and forgiving
02 -
  • The cake base must be completely cool before adding raspberry layer, or the gelatin wont set properly
  • Egg whites must be whipped in a completely clean bowl—any fat prevents proper volume
  • Melted chocolate thats too hot will cook the egg yolks and make the mousse grainy
03 -
  • Run a thin knife around the edge before releasing the springform pan for clean sides
  • Warm your knife under hot water and wipe dry between slices for perfect portions
  • Let the finished cake sit at room temperature for 15 minutes before serving—the mousse becomes silkier
