Recipe Tips and Notes

  • I recommend lining the cake pans with parchment paper rounds after greasing them. Simply trace the bottom of a cake pan on parchment paper and cut them out. It takes a bit more time but makes removing the cakes much easier. 
  • If the cakes come out of the oven slightly domed, cut the the tops off with a sharp knife so they are perfectly flat before assembling. This will make the cake look more professional.
  • Other berries such as raspberries and blackberries can be used in place of strawberries for this mousse. If you do use one of these berries, make sure that the seeds are strained out.

  • 35 g /1/3 cup cocoa powder
  • 3/4 tsp baking soda
  • 3/4 tsp baking powder
  • 1/2 tsp salt
  • 1 egg
  • 125 ml /1/2 cup milk
  • 60 ml /1/4 cup vegetable oil
  • 1 tsp This is an affiliate link.vanilla

For the strawberry mousse

  • 2 large eggs, separated
  • 4 tbsp superfine/caster sugar
  • 190 ml /3/4 cup blended fresh or frozen and thawed strawberries
  • 3 tsp gelatine
  • 3 tbsp water
  • 250 ml /1 cup double cream/whipping cream

For the decoration

  • 125 ml /1/2 cup double cream/whipping cream
  • 2 tbsp icing sugar
  • 1/2 tsp This is an affiliate link.vanilla
  • 3-4 strawberries, halved

Instructions 

For the chocolate cake

  • Preheat your oven to 350 F/180 C, butter and line a 9 inch cake pan with parchment paper.
  • Mix together flour, sugar, cocoa, baking powder, baking soda and salt in a large bowl until combined. In a separate bowl mix eggs, milk, oil and vanilla essence. Add the wet ingredients to the dry ones and beat with an electric mixer until well incorporated.
  • Pour into the prepared pan and bake in the preheated oven for 25-30 minutes or until a toothpick comes out clean. Cool in the pan for 10 minutes, then remove the cake from the pan and cool completely on a wire rack.

For the strawberry mousse

  • Separate the egg yolks from the egg whites. Process the strawberries in a blender or a food processor until smooth. If using frozen strawberries, thaw them first and drain the liquid before processing. Beat the egg yolks and sugar until light, then whisk in the processed strawberries.
  • Sprinkle the gelatin over the water in a small bowl and allow to go spongy, then put in the microwave for 30-40 seconds until the gelatin has dissolved. Stir in the strawberry, egg yolk and sugar mixture.
  • Whip the cream until holding its shape and fold into the mousse. Whisk the egg whites until standing in soft peaks, then fold in. Let stand in a cool place until starting to set; between 10-15 minutes. Cut the cake into 2 layers with a long, sharp knife.
  • Place one layer back in the springform pan and pour in the mousse (it shouldn’t be runny!) and let it set for 1 hour in the refrigerator. Place the top layer directly on the mousse layer and continue chilling for 2 more hours or until ready to serve. Whip the cream with icing sugar and vanilla.
  • Decorate the top of the cake with fresh strawberries and pipe cream rosettes around the edges.

Notes

As the eggs in the mousse are not cooked, however tempered by the hot gelatine mixture, I have used free-range and organic eggs to be on the safe side.

    can you assemble and freeze the cake for a week or so, then top off with the whip and berries once you’ve pulled it from freezer?

    1. Julia Frey (Vikalinka) says:

      Hi Glenda, I haven’t tested it to be absolutely sure but my guess is that you can. I would actually freeze it in the springform it is made and cover it with multiple layers of clingfilm.

  2. Linda Pascoe says:

    I made this cake a few months ago and took it into the op shop where I volunteer. All the ladies loved it (even the few men), especially the manager who claimed it was the best cake I had taken in to the shop. Our manager is soon retiring, so this cake would be the perfect send off for her. Easy to make, light and delicious. Thank you for the recipe.
