To garnish:

  • Salted caramel chocolate ganache – optional

To make the sponge base:

  • Preheat the oven to 350ºF/180ºC/Gas Mark 4. Grease and line 2 round cake tins. Next, using an electric mixer, beat the eggs and sugar until light and creamy, then add all the remaining ingredients for the sponge cake base and whisk until well combined (around 3 minutes).
  • Divide the batter between the 2 cake tins and bake for around 20-25 minutes, or until golden brown and firm.
  • Remove and let cool before turning out onto a cooling rack. In the meantime, make the mousses.

To make the caramel mousse:

  • In a small bowl or cup, combine the gelatin and water. Let sit for 3 minutes.
  • In a medium saucepan, heat sugar over low until it is melted and turns a dark amber- to make a dry caramel. Meanwhile, in another saucepan heat up the heavy cream.
  • Gradually, apply the warm heavy cream into the caramelized sugar. Then, stir well and remove from heat immediately. Set aside to cool completely.
  • When this mix is quite warm (not hot), place in the softened gelatin and salted butter and combine until well incorporated. Sieve the mix.
  • To finish, beat the sugar and heavy cream until soft peak form. Apply into the caramel mix. Using a spoon or spatula, combine well.
