For the chocolate ganache

  • 200g plain chocolate, broken into pieces
  • 225ml double cream


  1. Pierce the orange with a skewer (right through). Cook in boiling water for 30 minutes until soft. Whizz the whole orange in a food processor until smooth; let cool.

  2. Preheat the oven to 180C/gas 4/fan 160C.Grease and line the base of a 23cm/9in round cake tin. Melt the chocolate in a heatproof bowl set over a pan of simmering water or in the microwave for 2 minutes on High, stirring after 1 minute. Let cool.

  3. In a large bowl, lightly beat the eggs, sugar and oil. Gradually beat in the puréed orange, discarding any pips, then stir in the cooled melted chocolate. Sift in the cocoa, flour and baking powder. Mix well and pour into the tin. Bake in the centre of the oven for 55 minutes, or until the cake springs back when lightly pressed in the middle. (Check after 45 minutes and cover with foil if it is browning too much.) Allow to cool for 10 minutes in the tin, then turn out on to a wire rack to cool completely.

  4. Make the chocolate ganache: put the chocolate into a heatproof bowl. Bring the cream to the boil and pour over the chocolate. Leave for 2 minutes, then stir until smooth. Set aside until firm enough to spread over the cake – up to 1½ hours.

  5. Transfer the cake to a serving plate. Using a palette knife, swirl the ganache over the top. Decorate with strips of candied orange peel.

Absolutely lovely, a bit like eating a chocolate orange in cake form! I made a little less topping which came out just right

This is so yummy! I have made it a few times now and it's always a hit... Making it today for my father in laws birthday and putting Terry's chocolate orange segments on top (his favourite) :) Thank you for sharing!

Please be aware you don't have to boil the orange, you can use a normal one but you can just microwave it for 10 minutes then leave it to cool before blitzing it. I make the other version that is wheat free but i'm going to try this one tonight instead without the ganache!!

Delicious! The orange flavour carried through amazingly to add a fresh tang to a very rich cake. The cake rose well and both times I've made it I found it was better without the overwhelming frosting. I found that by substituting half the flour for almond meal and a quarter of the caster sugar for brown sugar the cake was even more rich and had a darker and deeper flavor.

Made a trial run of this cake for a friend's birthday coming up. I wasn't to happy with it as the cake was too dense. But on the up side had I had happy colleagues!

Pretty easy to make and tastes devine! Be careful to blend the orange really well though as there might be some hidden lumps. If you make it in a fan oven it will bake a lot faster than 55 minutes so keep an eye on it. It says 55 minutes but I was able to take mine out after just 35. I will definitely make it again!

It was almost really good, but too dry at 50 minutes (yes, I had an oven thermometer) and it needs 80% dark chocolate, not plain. Also, I would add the zest of an orange to the mix to boost the orange flavour!
