Instructions
Prepare equipment and ingredients
Gather all utensils, measure the ingredients and preheat the oven to 180°C.
Time: PT3M
Temperature: 180°C
Whisk eggs and sugar
In the bowl, whisk the eggs and sugar on high speed until the mixture triples in volume and becomes pale.
Time: PT8M
Incorporate dry ingredients
Sift the flour, unsweetened cocoa, baking powder and salt directly onto the egg‑sugar mixture. Gently fold with the spatula, lifting the batter from the bottom of the bowl.
Time: PT5M
Whisk the cold cream
Pour the very cold whole milk cream into a clean bowl and whisk on low speed until a thick consistency (soft peaks) is reached.
Time: PT5M
Fold in the whipped cream
Add the whipped cream to the batter in three additions, folding gently with the spatula so as not to deflate the volume.
Time: PT4M
Pour batter into the pan
Grease the 18 cm pan with the spray or butter and line it with parchment paper. Pour the batter and smooth the surface.
Time: PT2M
Bake the cake
Place the pan in the oven and bake for 30 minutes at 180°C. Check doneness with a knife tip that should come out dry.
Time: PT30M
Temperature: 180°C
Unmold and cool upside‑down
When the cake is out of the oven, turn the pan onto a rack, unmold the cake which releases thanks to the spray, then let it cool upside‑down to flatten the dome.
Time: PT8M
Remove the dome and cut the layers
Once the cake is completely cool, cut off the domed top with a knife. Use a cake leveler to obtain three discs of equal thickness.
Time: PT5M
Prepare the syrup
Bring 100 ml water to a boil with 50 g sugar for 2 minutes, then let it cool.
Time: PT4M
Temperature: 100°C
Cut the strawberries
Wash, hull and dice the strawberries into small cubes. Reserve some for decoration.
Time: PT4M
Soak the cake layers
Brush each disc with the syrup using a pastry brush, ensuring they are well moistened but not soggy.
Time: PT3M
First assembly – mousse and strawberries
Spread about 1 cm of chocolate mousse on the first disc, then arrange a layer of diced strawberries.
Time: PT4M
Second assembly – mousse and strawberries
Place the second disc, soak it, then spread a new layer of mousse and add strawberries.
Time: PT4M
Third disc and final coating
Place the last disc, soak it generously, then completely cover the cake with a thick layer of chocolate mousse.
Time: PT5M
Chill and decorate
Put the cake in the refrigerator for at least 1 hour. Then, using a piping bag fitted with a star tip, pipe mousse around the cake and decorate with the remaining strawberries.
Time: PT6M
