Ingredients

  • 2 large oranges together they should weigh about 450g
  • 6 eggs medium, 60g each
  • 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 orange 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 orange 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.
This cake is naturally gluten-free and dairy-free

Ingredients

  • Navel oranges work beautifully here but any orange is good to use. Preferably waxless though.
  • If you can’t get hold of polenta then you can use fine cornmeal.

Baking Tips

  • I do recommend using a stand blender rather than an immersion blender (although it can be done if you only have the latter) as it will create the smoothest puree.
  • You can use a stand mixer for making the cake batter or you can beat the ingredients together by hand.
  • Allow the cake too cool in the tin. Place the tin on a cooling rack and if leaving unattended I often place a sheet of kitchen roll over the top to protect it.
  • The cake does sink a little in the middle due to the amount of chocolate chips in the recipe. If you prefer a cake with a more level look and less chocolate mayhem then reduce the amount of chocolate chips by a third.

Make Ahead

You can prepare the orange puree a day or two in advance. Once you have blended the whole oranges you can keep in the fridge until you are ready to make the rest of the cake.

Storing

It can keep well for up to 5 days if stored in an airtight cake tin in a cool dark place.

Freeze

  • You can freeze this cake as soon as it has cooled completely and before you drizzle with the chocolate. Double wrap in cling film and aluminium foil.
  • To defrost remove from the freezer and allow to cool completely at room temperature before unwrapping. Drizzle with the chocolate before serving.
