  1. Chocolate sponge cake
    • 200 gr. sunflower or neutral oil
    • 200 gr. white sugar
    • 180 gr. weak or pastry flour
    • 150 gr. eggs (3)
    • 100 gr. hot nespresso
    • 100 gr. buttermilk or milk
    • 60 gr. cocoa powder
    • 8 gr. baking powder
    • 5 gr. lemon juice

    • In the bowl of the mixer, start by beating the oil, eggs and sugar on medium speed for about 8 minutes until the mixture doubles in volume.
    • Meanwhile, in a glass, mix the milk and lemon juice and set aside for about 5 minutes. If you use buttermilk, it is not necessary to add the lemon juice.
    • By mixing milk and an acid, such as lemon juice, we obtain something similar to 'buttermilk', which will make our sponge cake more tender, fluffy and light.
    • When the milk has separated due to the action of the lemon juice, add it to the previous mixture.
    • Now, sift the flour, cocoa powder and baking powder, mix it and add it to the previous mixture in two or three times. Mix just until combined.
    • Finally, prepare a strong coffee and add it hot to the previous mixture. Stir well until the mixture is smooth, shiny and free of lumps.
    • Pour the batter into a 20 cm square baking tin and bake in the oven for 60 minutes at 170° C.
    • Leave to cool on a wire rack at room temperature and set aside.
  2. White chocolate ganache
    • 400 gr. heavy cream (35% fat)
    • 170 gr. white chocolate
    • 5 gr. gelatine
    • 5 gr. vanilla

    • First, hydrate the gelatine in cold water for 10 minutes.
    • In a saucepan, heat 120 g of cream together with the vanilla and bring to the boil.
    • Meanwhile, in a bowl, melt the white chocolate in the microwave in short batches.
    • When the cream comes to the boil, turn off the heat and pour it over the melted white chocolate.
    • Using a whisk, mix well until the cream blends with the white chocolate.
    • Finally, add the rest of the cream and process with a hand blender until you have a uniform, shiny cream.
    • Cover with cling film and refrigerate for at least 4 hours.
  3. Chocolate coating
    • 250 gr. dark chocolate (62%)
    • 165 gr. butter

    • In a saucepan over medium heat, melt the chocolate and butter in a bain-marie.
    • When the mixture has melted completely and is smooth and homogeneous, remove from the heat.
    • Set aside at room temperature until ready to use. Reheat to 40º C before use.
  4. Assembly

    • Start by removing the top of the sponge cake, if necessary, to make it flat, and cut it into two sheets of equal thickness.
    • Then, place one of the sheets in the same 20 cm square mould we used before.
    • Next, take the white chocolate ganache out of the fridge, whip it to firm peaks and spread it on the sponge sheet, using a spatula to smooth it out.
    • Then place the other sheet of chocolate sponge cake on top and set aside in the refrigerator for at least 4 hours, ideally overnight.
    • After this time, carefully unmould the cake and cut 5 mm off each side so that the layers of our cake are well shaped. Cut our cake in half to obtain two equal rectangles.
    • Finally, heat the chocolate coating to 40° C, place the two cakes on a wire rack and pour the coating over them. Remove the excess with a spatula.
    • Allow the chocolate to cool to room temperature and store in the refrigerator until ready to eat. Leave for 20 minutes at room temperature before serving.
