  3. Fold half of the whipped cream into the chocolate mixture until smooth, then gently fold in the remaining whipped cream.
Assembly
  1. Spread half of the chocolate mousse over the chilled crust.
  2. Spoon raspberry preserves evenly over the mousse and scatter fresh raspberries on top.
  3. Spread remaining mousse over the raspberry layer and smooth the top.
  4. Refrigerate for at least 6 hours or overnight until fully set.
  5. Carefully release from the pan, garnish with extra raspberries if desired, and serve chilled.
