Equipment

  • springform pan
  • mixing bowls
  • electric mixer
  • spatula
  • fine mesh sieve
  • saucepan

Ingredients

  • 4 eggs
  • 100 g granulated sugar
  • 50 g brown sugar
  • 1 tsp vanilla extract
  • 80 g all-purpose flour
  • 25 g cocoa powder
  • 1 tsp baking powder
  • 1/2 tsp espresso powder
  • 1/4 tsp salt
  • 100 g dark chocolate (75%), melted
  • 300 g fresh raspberries
  • 100 g granulated sugar (for mousse)
  • 2 tsp powdered gelatine
  • 2 tbsp lemon juice
  • 400 ml heavy cream

Instructions

  • Preheat oven to 350°F (180°C) and prepare a lined 9-inch springform pan.
  • Whip eggs, sugars, and vanilla for about 4 minutes until pale and thick.
  • Sift in dry ingredients and mix gently on low speed until just combined.
  • Fold in melted dark chocolate until smooth, ensuring no pockets remain.
  • Pour batter into pan and bake for 15–20 minutes. Cool completely and refrigerate.
  • Bloom gelatine in lemon juice and let it soften for a few minutes.
  • Blend raspberries, strain seeds, heat gently with sugar, then dissolve gelatine. Cool to room temperature.
  • Whip cream to soft peaks and gently fold in cooled raspberry mixture in batches.
  • Pour mousse over chilled sponge, smooth the top, and refrigerate at least 3 hours or overnight.
  • Remove from pan, decorate with raspberries and chocolate shavings, slice, and serve.

Notes

Whip eggs and sugar thoroughly for a proper genoise structure. Do not overmix after adding dry ingredients. Let raspberry puree cool completely before folding into cream. Never boil gelatine. Chill overnight for best texture and clean slices.
