Serves: Serves 10
Ingredients
For the cake:
  • 2½ cups (375g) all purpose flour
  • 1 cup (95g) unsweetened cocoa powder
  • 2½ tsp baking powder
  • ¾ tsp baking soda
  • 1 tsp salt
  • 1 stick (115g) butter, melted
  • 2 cups (400g) caster sugar
  • 2 eggs + 1 egg yolk
  • 2 tsp vanilla bean paste
  • 1½ cups (375ml) milk
  • 1 cup (250ml) just boiled water
For the frosting:
  • 3 sticks (345g) butter, soft
  • 5½ cups (690g) confectioner's sugar, sifted
  • ½ cup (50g) unsweetened cocoa powder, sifted
  • 1½ tsp pure vanilla extract
  • pinch of salt
  • ¼ cup (60ml) sour cream
  • 8oz (225g) semisweet chocolate (dark chocolate 70%), melted and cooled
  • Optional: edible gold glitter
Instructions
  1. Preheat the oven to 350F/180C. Grease and line three 18cm/7in cake tins.
  2. Sift together the flour cocoa, baking powder, baking soda and salt and set aside.
  3. In a very large mixing bowl whisk together the melted butter and sugar. Add in the eggs and vanilla and beat until everything comes together in a homogenous mix.
  4. Whisking constantly (you need a strong whisk) add the sifted flour mix in three batches, alternating with the milk. Scrape the bowl as needed, and finally, whisk in the hot water.
  5. Divide the batter between the three pans and bake for 23-25 minutes, or until springing back when pressed and a skewer in the centre of the cake comes out clean.
  6. Leave to cool in the tins for 5-10 minutes, and then turn out onto a wire rack to cool completely.
  7. Make the fudge frosting: in the bowl of a stand mixer fitted with the paddle attachment, beat the butter until smooth and creamy. With the mixer on low, gradually add the confectioners' sugar, cocoa powder, vanilla and salt. Add the sour cream and mix until incorporated. Turn the mixer to high and mix until for about 30 seconds - just to lighten the mix. Stop the mixer and scrape down the bowl. Add the chocolate and mix on low until smooth.
  8. To assemble the cake, trim the layers if they are domed, and then place the bottom layer (the ugliest or thickest one) onto a serving plate. Top with one third of the frosting, and spread it just shy of the edge (the other layers will squish it out to the edge). Repeat with the remaining layers and frosting, aiming for a swirly, messy look.
  9. Scatter the top with edible gold glitter, if desired.
