    • 300ml double cream
    • 2 tbsp golden caster sugar


    1. Heat the oven to 160C/ fan140C/ gas 3. Butter and line a 20cm round cake tin (7.5cm deep).

    2. Put 200g chopped dark chocolate in a medium pan with 200g butter.

    3. Mix 1 tbsp instant coffee granules into 125ml cold water and pour into the pan.

    4. Warm through over a low heat just until everything is melted – don’t overheat. Or melt in the microwave for about 5 minutes, stirring halfway through.

    5. Mix 85g self-raising flour, 85g plain flour, ¼ tsp bicarbonate of soda, 200g light muscovado sugar, 200g golden caster sugar and 25g cocoa powder, and squash out any lumps.

    6. Beat 3 medium eggs with 75ml buttermilk.

    7. Pour the melted chocolate mixture and the egg mixture into the flour mixture and stir everything to a smooth, quite runny consistency.

    8. Pour this into the tin and bake for 1hr 25 – 1hr 30 mins. If you push a skewer into the centre it should come out clean and the top should feel firm (don’t worry if it cracks a bit).

    9. Leave to cool in the tin (don’t worry if it dips slightly), then turn out onto a wire rack to cool completely. Cut the cold cake horizontally into three.

    10. To make the ganache, put 200g chopped dark chocolate in a bowl.  Pour 300ml double cream into a pan, add 2 tbsp golden caster sugar and heat until it is about to boil.

    11. Take off the heat and pour it over the chocolate. Stir until the chocolate has melted and the mixture is smooth. Cool until it is a little thicker but still pourable.

    12. Sandwich the layers together with just a little of the ganache. Pour the rest over the cake letting it fall down the sides and smooth over any gaps with a palette knife.

    13. Decorate with 50g grated chocolate or 100g chocolate curls. The cake keeps moist and gooey for 3-4 days.

    I have tried to do this cake 3 times and it has never succeeded. I have followed the recipe though also read comments and taken advice on board. It tastes good but breaks up as soon as I go to remove it from the tin. The third time I tried to adapt and make muffins but they just spilled all over the pan and failed to rise.

    I made this cake but was somewhat disappointed at the way it looked. Taste wise it was out of this world. However when testing with a knife to see if done, the top was crunchy and when I put in the knife it collapsed. So not nice to look at but trade was amazing. Could've been something I missed but posting comment in case others had same experience. Would've been five star had it not collapsed.

    Made this cake for my son's birthday. It turned out perfectly, so moist and fudgy. I used the exact ingredients (dark cooking chocolate from Morrisons with 56% cocoa solids worked well) and will definitely make again without changes to those. From reading the reviews was a bit nervous about cutting, but made sure the cake was completely cool before doing. Although I cut in half rather than into three as didn't think that was a risk worth taking! There was enough ganache for filling and icing and again if you follow the ingredients and recipe for this you won't go wrong.

    Made this today , but wish I'd viewed comments first. I found the cake near impossible to cut in half without it crumbling so should definitely of used sandwich tins instead. Also it tasted more like a chocolate brownie rather than a cake. It did taste nice though with the ganache used as a dipping sauce (I used an extra 50ml of cream to stop it setting firm)

    Great recipe. Creates a really intense, rich, moist chocolate cake. The recipe is very easy to follow. It went down very well with all my work colleagues.
    23rd Jun, 2019
    Note I'm giving this 5 stars if you dramatically cut the sugar down! I used 140 of each and it was so sugary I had to throw it out. Next time I'll use 80 of each and see how that works out. Amazing recipe though like a giant brownie but deffo make in two tins if you're going to sandwich

    I made this cake for the first time for a birthday party and it turned out perfectly. I froze it immediately after baking (once it was completely cool), and the night before the party, I defrosted it, and then iced it with the ganache in the morning. Very easy recipe, which I followed to the letter. The hardest part was cutting the cake in half, as it is quite delicate. Next time, I think I'll make it in two sandwich tins and reduce the baking time.

    Brilliant! Just brilliant! Try this recipe out sometime! :-)

    I've made this twice now and it's incredible. Both times I've used the same oven temperature but used sandwich tins and cooked it for 45 minutes, it was perfectly cooked. The first time, I used the exact ingredients as listed. The second time I needed to make it dairy and soya free, you wouldn't have been able to tell! For your interest, I used stork baking spread and dairy and soya free dark chocolate. To replace the sour cream, I used 75ml Oatly barista milk mixed with 1tsp lemon juice and left it to sit for half an hour. For the ganache, I melted 80g of Trex vegetable fat with 250ml Oatly single cream and used the same chocolate as above along with the sugar in the recipe. It was delicious!

    Amazing chocolate cake......

    I've made this cake a few times before, once cutting it in half, and twice using two cake tins. Would I be able to bake it in three cake tins and reduce the baking time, so I could have three layers without having to cut it, or would they be too thin and probably end up too dry?

    Thanks for your question. You try could dividing the cake mixture into three but as you say, the layers may be a bit thin. You'd also need to reduce the cooking time to avoid overcooking and drying out the cake. We are unable to give exact timings without testing. The other options is to make as is and slice into three layers. If you do decide to give it ago, let us know how you get on.

    I want to make this in a square 12" x 12" - how much more cake mixture will i need?

    Thanks for your question. Unfortunately we can't give exact measurements or timings without retesting.

    Do you gave a version with US measurements/ingredients/oven temperature?

    Thanks for your question. We don't have a US version on this site but if you use an online conversion guide, it is possible to make the switch. Good luck!

    I love this cake but I'm wanting to make more of it for my daughter's first birthday party. If I follow the standard recipe and then tweak it to bake another smaller one to put on top, can the cake hold it up if I use dowling/straws? Not built a tiered cake before...
    goodfoodteam's picture
    3rd Dec, 2018
    Thanks for your question. The cake should be strong enough to hold one more small tier, especially with cake dowels. We'd recommend layering the cake and then putting ganache on the whole thing in one go for the best finish.

    Fantastic thank you!

    Hi. I'm going to try this this weekend to see if it will work for Christmas. I only have 23cm or 17cm springform tins though. Will it still work /rise properly? Thanks for any help.

    What a deliciously morish cake! Amazing is not enough to describe it... The coffee cuts the extreme sweetness but you can barely notice the flavour. I was told by someone it was quite heavy and brownie like (which i totally loved about it!) so made it lighter by using only self raising flour, with spectacular results Tip1: use decaf cofee for a kid friendly version Tip2: replace the plain flour for self raising for a fluffier texture, works really well Tip3: its easier to cut the following day from baking

    Amazing proper chocolate cake but here's 4 tips to help you make it even better and easier: 1) Use a bain-marie (i.e. a bowl over a pan of softly boiling water) to melt the chocolate and butter together. This prevents the chocolate from spoiling or splitting. Do the same when making the ganache. 2) Don't mix the coffee and water into the chocolate and butter. Oil and water don't mix well and are likely to split. Just add the coffee and water mixture later when you bind all the ingredients together. 3) Use 160g of each sugar. 200g is too much. 4) Leave the ganache to cool then whip with a whisk it to firm it up. It will then spread and hold beautifully. Enjoy the cake!

    Consider less sugar as way too sugary

    Don't make it

    I made this as per recipe but put it in an 8.5" cake tin, which was only slightly larger than recommended. I checked it after 55 mins on 150 c in a conventional oven. Despite being on the lower shelf it was already beginning to over cook. Please check your cake at about the hour mark. If I make it again I'll cover with grease proof paper at 45 mins. I rescued it by scraping the top very slightly and dousing with a generous helping of golden rum. Ganache as per recipe. Gorgeous 'Jamacian' chocolate cake. Recommended.

    I never have buttermilk and use a 1/2 greek yogurt and 1/2 milk mix. This cake is incredible!

    I made this for my niece's engagement party and it went down a storm with many requests for the recipe! Comfortably serves 20 as it's very rich.

    How To Make Chocolate Cake – Pointers To Consider Once you have mastered the art of baking and know how to make chocolate cake, there are few things you need to take into account. For example some people are vegetarians and do not eat eggs, so you will need to prepare Eggless cakes for them. Many people even don’t like having sour cream or butter. So what you can do is have some substitutes in place of the eggs like rice flour. However if you use rice floor, be prepared for the cake batter to remain thin. The other thing is to make sure that the cake recipe is followed properly and the teaspoonful or tablespoonfuls of the ingredients are taken in the right amount. So now that you have some idea of how to make chocolate cake, wow your friends with your baking prowess! info taken from: http://www.howtomakechocolatecake.org/make-chocolate-cake-cool-tips/

    I baked this for my brother's birthday the other day. Everyone was thrilled by it! I should say I changed couple of things. - Good I had my eye on and took it out of the oven after 1 hour, otherwise it would have been a burned mess, even after just 1hr I noticed dry edge, but that was ok and fixable. - I used 6 tbsp of milk instead of buttermilk. - I don't know how it is possible to cut to 3 layers, I just made 2 layers. It was a bit flaky to be cut to 3 layers. - For the filling I used 200gr whipped cream mixed with part of dark melted chocolate. sprinkled with chopped walnut and hazelnut inside and out. - Unfortunately there was no brown sugar, so I used regular. For my taste it was a bit too much, next tie will use half or 3/4 portion. - I used 70% dark chocolate which somehow gave a feeling of alcohol in it, but there was none. way to go recipe, everyone loved-loved it! it tastes even better the next day, well if any piece is left. for us tehre was just a tiny piece for the morning
