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.

I would give this recipe 4 stars because i didn't find it very orangey, however i think this is because i used the wrong type of orange, which is my fault. The texture of the cake was really nice and it was the perfect chocolatey taste as well, i will make this again, just using the right oranges.

Really yummy cake! Only needed 45 minutes in the oven though, and that being said, every time I've made it it still comes out dry - suggestions?

Superb! Bit dubious at first about putting a whole orange in peel included but the puree it created was lovely. So yes to those asking, boil the whole orange and skin. Then place whole orange with skin in blender. The cake is fairly rich but so very good. It didn't last that long I would say with the freshness. A day later and the sponge was a little dry. Will make again though. I definitely halved all the topping ingredients - more than enough covering with just half. Plus a lot cheaper too!

Planning to make this cake. Is orange boiled and pureed with skin?
10th Mar, 2020
Yes - boil and blend the whole orange - it adds flavour and moisture - delicious

I bake this as the basis for cake pops, birthday cakes and it is a hit! Everyone comments on the moist, lovely orange and chocolate taste! It was well received as a cake donation to Macmillan coffee event locally and it was a success! Love the recipe!

This is a fantastic recipe!! Made the cake as cupcakes and baked it for about 20 minutes, can't remember exactly. It was really, really delicious. The orange flavour did come through even though I didn't use orange flavoured chocolate, just plain dark chocolate as the recipe recommends. It is a subtle flavour but really good, it's quite sophisticated and not too sweet. I didn't have any cream so just made a chocolate buttercream for the top and I thought it went together very well. Decorated with some chocolate shavings and candied peel. It was for a coffee morning and got loads of compliments, people really liked them. One of the best bakes I've ever made! Original and unique as well as scrummy :)

Can I substitute the sunflower oil for another oil?

Hello, Yes you can, use another oil without a strong flavour. I hope this helps.

Are we supposed to use orange with skin on it?

Sounds like a strange idea but yes!

I'm planning to to make this a day in advance. Should I put the ganache on the day before, or wait until the day I'm serving? Or does it not really matter? Thanks.

If you want to get ahead put the ganache on the cake the day before and keep in a cool place rather than in the fridge.

Just wondering if it was possible to freeze this cake once completed

Do you boil and purée the orange including the skin? :/

I used tangerine and a substitute for the orange and the results and even more fragrant. Be sure to check when the cake is ready. In my oven it took only 35 minutes to cook perfectly.

This cake is really lovely but I usually substitute the orange for two limes which also makes a really lovely cake.
