  1. First make the jelly. Grease a 20cm round cake tin and line with cling film (you can use the 23cm tin that you will bake the cake in, but you’ll have to make this the day before so that you can remove it before making the cake). Remove the zest from 4 of the oranges and set aside for the cake. Tip the orange juice and sugar into a saucepan and gently heat to dissolve the sugar. Meanwhile, soak the gelatine leaves in cold water for a few mins until soft. Remove the gelatine from the water, squeeze out any excess and add to the warm orange juice, stir until the gelatine has dissolved. Pour the liquid into the lined cake tin and chill for at least 4 hrs or preferably overnight.
  2. Heat oven to 160C/140C fan/gas 3 and line a 23cm round cake tin with baking parchment. Tip all the cake ingredients into a large mixing bowl and combine with an electric hand whisk until smooth. Spoon into the tin and smooth over the surface. Bake in the centre of the oven for 55 mins, or until a skewer inserted comes out clean. Cool in the tin for 15 mins, then invert onto a wire rack and leave to cool completely.
  3. Now make the ganache. Heat the cream in a small pan until hot. Put the chocolate in a small bowl and pour over the cream, leave for 10 mins, then mix well – you should be left with a smooth chocolate sauce. Leave at room temperature until the ganache cools and thickens a little (you can put it in the fridge to speed this up, but keep an eye on it, as it will set quickly).
  4. To assemble the cake, place it on a cake stand and trim the top to give you a flat surface. Warm the apricot jam in the microwave until a little runny. Paint it over the top of the cake, then flip the orange jelly out of its tin, and position on top. Using a palette knife, swirl the chocolate ganache over the orange jelly, letting it dribble down the sides of the cake a little. Serve straight away or within 24 hours.

I can't comment on the baking of the cake, but my mum just made this for my brother's birthday and it was FANTASTIC!!! She did have a bit of trouble with the ganache being a bit melty, but it WAS a record-breaking hot day! it melted a bit and ran down the cake, but after putting it in the fridge for a short time, the ganache firmed up a little and we were able to spread it around the sides of the cake. Reading other comments about difficulties making the jelly and problems with ganache, I would say persevere! The end result is a real show stopper and sooooo delicious, that for a special occasion it's well worth it!

Nice BUT - I found the ganache too runny (perhaps less cream should be used?), and others have written the jelly slid off the cake (I don't know whether this was to do with the ganache or the fact that I put Jaffa Cake halves on top of the cake and pushed them down into the jelly slightly.
Otherwise I would leave out the jelly completely and use just apricot jam on top of the cake and then place ganache over the top.

If I was to do this recipe again I would cut a large circle into the top of the cake (a centimetre deep) and leave a border between the edge of the cake and cut out hole. I would then place the jelly in that hole, which would prevent it from sliding off the cake.
As for the ganache I would probably use 200ml of cream rather than 300ml or make a completely different icing recipe.

Made this with a veggie gel sachet, for my daughters birthday Worked very well but the gel and cake kept on separating as it was served, not that it mattered as it tasted lovely. Perfect for fussy new vegetarian teenagers.'s picture

Made this over Christmas it was wonderful!
The only change we made was how we made our ganache we did ours on the heat and then let it start to set in the fridge before we put it on so it was less runny makes it easier to spread.
The jelly was lovey and soft make sure you use good quality gelatin leaves. It's easy to get out of the tin if you leave the jelly to set over night line cake tin with cling film. Making the jelly was easy if you follow the instructions, it took us 6 oranges to get about 450ml of juice the rest was easy :D
The cake its wonderful! ignore bad reviews just take your time and enjoy it!!

When I made this it looked and tasted absolutely fantastic! It IS a bit of a big effort to make the jelly yourself, so not a cake to make at the last minute. I also found that letting the jelly set in a 20cm tin made it rather thick, and was quite tough. Ended up removing most of it when eating the cake.

I made this today, tastes great but looks a complete mess and for that reason only I wouldn't make it again! The sponge fell apart and the chocolate did not stay on the orange jelly.

Made this cake for dinner party. It looked and tasted fantastic wennt down very well. Put some orange liquor in the jelly and used more gelatine than recipe states. Would make again.

Made this last night, all was going well till putting the jelly on the sponge. A tiny crack appeared. Still thought all was well ..........then the very runny chocolate, it just split all the jelly Manage to save it by taking off the Jelly and removing some of the sponge so the jelly sat just inside the cake. Coved it up with choc so as to cover up my mess. IT tasted good but i wouldn't be bothered to make it again.

Well just had a go at this gorgeous looking cake and it completely bombed! The jelly I had made was difficult to get in the cake in the first place but with perseverance I managed it with only a small tear to the centre. I then delicately and slowly pored the chocolate and it ate into the split, destroyed the jelly which ended up sliding off and in a pool on the plate! Acre ally disappointed think it should not be classed as moderately easy, more like very time consuming and costly. Pack of Jaffas now owed to my office who were quite excited by this cake prospect!

As previous posters have mentioned, the ganache doesn't stick to the jelly (I used only half the amount of cream stated). Also, the jelly did not set the first time (though I've jellied fresh-squeezed orange juice many times before and this recipe calls for more gelatin than I'd usually use for the amount of juice).
It looked quite good initially, but after walking to work with it the next morning, the jelly had melted slightly and oozed though the ganache. Not the prettiest sight! It wasn't easy to cut either (keep it in the fridge and the ganache hardens too much, keep it out and the jelly melts!).
Tasted good though!

Not a brilliant success, I read the other comments and made the ganache with 200ml cream rather than 300ml, but it was still a bit thin and there was still a reaction between the chocolate and the jelly. I used marmalade instead of apricot jam for the 'glue', only because that was all I had.
The jelly slides off the cake very easily, and I wonder whether the jam is needed at all...

Total disaster - I have no idea how on earth it could wait 24 hours to be eaten. It looked amazing just after assembly, so at first I thought it was pretty awesome. I then had to transport it by car, and within 2 minutes of careful driving, the jelly had slid off the top and broken up. By the time I arrived, all the chocolate had somehow dissolved - I agree with the other comment which said the chocolate is too runny. I think it needed a really firm chocolate to hold the jelly in place and to prevent it from reacting with the moisture in the jelly layer. It now looks pretty horrible :-( I'm not sure anyone will want to eat it. Very disappointing, as usually Good Food recipes come out perfectly, especially the cakes.

Husband made this for my birthday. Excellent cake! The combination of light sponge, very zingy jelly, and rich ganache was great. We used Vege Gel to avoid the gelatine.

Was very pleased with how cake turned out. Sponge was lovely and light, jelly was a bit tricky to turn out but very tasty and the ganache worked out fine. All in all, a delicious cake which went down well with my daughter and her friends at her birthday party. Cake is pretty rich and substantial, so found that cake could be cut into lots more than 10 slices.

started out well then went disastrously wrong, jelly was delicate so it broke whilst being turned out and then was sliding off the cake because the jam had made it all slippy, then the ganache was like water. To be honest you'd need to see my photo of it to believe the state of it. A lovely idea but OMG

Cake and jelly were fantastic and turned out really well, however I was disappointed with the consistency of the ganache which was far too runny. I'd probably use far less of the cream next time. Other than that, it was demolished in no time!
