Ingredients

  • 2 large oranges together they should weigh about 450g
  • 6 eggs
  • 250 g caster sugar
  • 125 g polenta
  • 125 g ground almonds
  • 1 tablespoon baking powder
  • ¾ teaspoon sea salt
  • 375 g dark chocolate chips use vegan chocolate if you want the cake to remain dairy-free

Orange Syrup

  • 1 tablespoon honey
  • 1 tablespoon juice of an orange

Instructions

  • Place the oranges in a saucepan and cover with water. Bring to the boil and then simmer for 1 hour until soft.
  • Pre-heat the oven to 150°C (fan oven)* and line and grease a 8 inch round x 4 inch deep cake tin.
  • Remove the oranges from the saucepan and cut in half to remove and discard the pips.
  • Place the oranges in a blender and blitz until smooth and set aside for a minute.
  • In a large bowl or food mixer beat the eggs and sugar together until pale and thick then mix in the pureed orange.
  • Add the polenta, ground almonds and baking powder and mix until thoroughly incorporated.
  • Finally stir in 250g of the chocolate chips (saving the extra 100g for the chocolate drizzle on top) until evenly dispersed.
  • Pour the batter in the prepared cake tin and bake for 10 minutes then turn the heat up to 160°C. Bake for a further 40 minutes until firm to the touch and an inserted toothpick comes out clean.
  • Once the cake is ready, remove from the oven and prepare the honey syrup by dissolving the honey in the orange juice in a saucepan on medium heat. Once dissolved and reduced slightly, prick the cake all over with a toothpick and brush the honey syrup evenly all over the surface of the cake.
  • Leave the cake to cool in the cake tin.
  • Once the cake has cooled and been removed from the cake tin then prepare the chocolate drizzle by melting the remaining 125g of chocolate chips in a bain marie or bowl set over a pan of simmering water. Pour the melted chocolate into a piping bag (or a small plastic food bag – just snip the corner off when you are ready to drizzle) and leave the chocolate to thicken slightly for about ten minutes before drizzling over the cake.

Notes

*I like to use a fan oven for this cake as it is so moist that the fan helps the cake bake more evenly. However, if you don't have a fan oven then just increase the initial heat to 170°C, bake for 10 minutes then increase the heat to 180°C.
