Ingredients Equipment Method Notes

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

Equipment

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

Method
 

  1. Preheat oven to 350°F (180°C) and prepare a lined 9-inch springform pan.
  2. Whip eggs, sugars, and vanilla for about 4 minutes until pale and thick.
  3. Sift in dry ingredients and mix gently on low speed until just combined.
  4. Fold in melted dark chocolate until smooth, ensuring no pockets remain.
  5. Pour batter into pan and bake for 15–20 minutes. Cool completely and refrigerate.
  6. Bloom gelatine in lemon juice and let it soften for a few minutes.
  7. Blend raspberries, strain seeds, heat gently with sugar, then dissolve gelatine. Cool to room temperature.
  8. Whip cream to soft peaks and gently fold in cooled raspberry mixture in batches.
  9. Pour mousse over chilled sponge, smooth the top, and refrigerate at least 3 hours or overnight.
  10. 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.
