  • ½ Cups Plain Flour
  • 2 Tablespoons Cocoa Powder
  • ⅓ Cups Caster Sugar
  • 4 Eggs
  • 80 Grams Butter, melted
  • 100 Grams Dark Chocolate, melted
  • 450 Grams Dark Chocolate
  • 2 Cups Pouring Cream
  • 6 Egg Yolks
  • ⅓ Cups Caster Sugar
  • Instructions

    Step 1

    Get ingredients (plain flour, cocoa powder, caster sugar, eggs, butter, dark chocolate and cream) out for both the cake and the truffle filling and place them on a bench or your kitchen workspace.

    Step 2

    Preheat your oven to 180° Celsius or 356° Fahrenheit.

    Step 3

    Grease (with butter) and line a 20cm spring form tin with baking paper.

    Step 4

    Sift plain flour and cocoa powder together into bowl, and set aside.

    Step 5

    Beat eggs and sugar with an electric mixer until pale, thick and it looks like it has tripled in size, or approximately 8-10 minutes.

    Step 6

    Meanwhile, measure out butter and dark chocolate and melt them together in a microwave, saucepan or over hot water.

    Step 7

    Once melted, stir butter and chocolate to ensure that it is all combined together and not burnt.

    Step 8

    Once the eggs and sugar have turned pale and increased in size, gradually mix slowly or fold in flour and cocoa.

    Step 9

    When the flour and cocoa have been added and combined into the mixture, slowly pour in melted chocolate and butter and beat until all well mixed together.

    Step 10

    Pour mixture into baking tin and bang to even and spread the mixture out. Put in oven and bake for 25 minutes or until the cake has shrunk away from the side of the tin.

    Step 11

    While cake is baking, start preparing the truffle filling. First measure out two cups of cream into a saucepan.

    Step 12

    Measure out other amount of dark chocolate into a bowl, this should be finely chopped to melt and combine more easily. This will be put into the saucepan with the cream.

    Step 13

    Heat the cream over low heat until almost at boiling point, it should become thicker.

    Step 14

    Pour in the chopped dark chocolate to the cream, which should be much thicker by now.

    Step 15

    Stir the cream and chocolate with a mixing spoon until chocolate is all melted.

    Step 16

    Once chocolate is completely melted and cream has thickened, it should look like this. Take it off the heat and let it cool.

    Step 17

    Separate the eggs, collecting the yolks and putting the whites in another bowl. Add the sugar to the bowl.

    Step 18

    Place bowl over a saucepan of simmering water to form a 'Bain Marie'.

    Step 19

    Whisk yolks and sugar for 6 minutes until thickened and creamy.

    Step 20

    Once the egg yolks and sugar have thickened, lift whisk up to check the consistency. It should look like this.

    Step 21

    Gradually pour melted chocolate and cream into the yolks and sugar mixture and mix.

    Step 22

    Mix with a whisk until it looks like this and starts to become cool.

    Step 23

    Take cake out of oven and set aside to cool.

    Step 24

    Place truffle filling in fridge for 30 minutes.

    Step 25

    After 30 minutes, take truffle filling out of fridge and get ready to assemble the cake.

    Step 26

    Slice cake into two even portions with a large knife. Lay bottom half in cake tin.

    Step 27

    Pour half of the truffle filling onto the bottom half of the cake and spread around.

    Step 28

    Lay the top portion on and coat with the remaining truffle filling.

    Step 29

    Bang cake on bench or kitchen workspace to level out filling or even it with an icing or cake knife.

    Step 30

    Place tin foil or glad wrap over the tin and refrigerate for at least 5 hours or until set like a mousse or ganache.

    Step 31

    Take cake out of tin using a warm knife and place on large plate.

    Step 32

    Cut slices out of cake to serve.

    Step 33

    Serve on a plate with nothing, or alternatively, whatever your desire! Enjoy!
