Ingredients

  • 1 14 cups plain flour
  • 14-12 cup cocoa powder (to taste for chocolate intensity)
  • 12 teaspoon baking soda
  • 1 teaspoon baking powder
  • 12 cup sunflower oil
  • 34 cup caster sugar
  • 14 cup yogurt
  • 34 cup orange juice (I used fresh squeezed)
  • 1 teaspoon orange zest
  • 1 14 cups icing sugar
  • 1 tablespoon orange zest
  • 12 cup golden sultana raisins
  • 2 tablespoons orange juice (I used fresh squeezed)
  • 2 tablespoons apricot brandy (optional)
  • 1 teaspoon vanilla extract
  • two pinches orange food coloring (optional)

Method

  • Preheat the oven to 180C (350F).
  • Lightly grease an 8" round baking pan.
  • In a bowl, sift together the flour, cocoa, baking soda and baking powder.
  • In another bowl, cream together the oil, sugar and yogurt.
  • Add the juice, orange zest and flour; mix well and pour into the prepared pan.
  • Bake for about 35 minutes or till the cake tests done; let it remain in the tin for 10 minutes, then turn it out onto a wire cooling rack.
  • When the cake is completely cool, split it in half horizontally.
  • To make the filling, put the sultanas, orange juice and apricot brandy in a small microwaveable bowl.
  • Cover with clingfilm, poke a hole in the top and microwave it for 2-1/2 minutes.
  • Let cool, then puree the sultanas - either smooth or coarsely
  • Pour the pureed sultanas into a mixing bowl, and add the orange food colouring (if using), the vanilla extract and orange zest and mix well.
  • Add the sifted icing sugar carefully and beat till the mixture is fairly thick, adding more icing sugar if required to make it spreadable but still firm.
  • Spread the filling on one half of the cooled split cake and top with the other half.
  • Sift icing sugar thickly over the top (perhaps vanilla sugar pulsed in the blender to make vanilla icing sugar).
  • Serve with a cup of strong coffee.
  • As an alternative to the orange-sultana filling, split cake and fill with thick orange curd (lemon curd with 50% or more orange juice), then top with ganache.
  • Non-chocolate eaters will find this delicious without the cocoa, adding another 1/4 cup of flour.
