Epic Chocolate Cake

Epic chocolate cake

Egads it’s hot! Stinking hot! Indeed such is the heat, that when you step outside and feel its blast, for a second you wonder if maybe you’ve magically teleported (with a spot of Harry Potter Floo Powder, naturally) to the Bahamas.

On the radio the other morning, there was a discussion about the things one least feels like eating in such weather and someone suggested baked potatoes. ‘Yes!’ I thought to myself, 'so true! What crazy person would force down something so dry, hot and stodgy in such heat?' I got my answer the next day when I went into work and discovered a colleague eating what else but a baked potato for his lunch. To his credit, he chewed and swallowed away stoically on his arid, heavy potato until he’d finished the last of it whilst I sat there balking incredulously at his abysmal choice of luncheon.

That made me realise though, we clearly all have different opinions about what to eat in extreme weather. For example, someone else suggested to me that it is too hot for cake. I'm sorry, what? Too hot for cake???!!! Pah! How sadly mistaken some people can be.

Consider this Epic Chocolate Cake that I’ve baked.  Whilst some may argue that it’s perfect comfort food for a cold winter’s day (and I wouldn’t disagree with you there), I see no reason why, with the right accoutrements, it couldn’t also be ideal summer food too. Say with a scoopage or two of vanilla ice cream, or some cold single cream generously sploshed over it.  Convinced? I thought you might be.

So yes, whilst a baked potato in this heat might be bordering on monster raving lunacy, let us all agree that it’s never too hot for cake.

Epic chocolate cake

This recipe is an adaptation of the now famous Epic(urious) Chocolate Cake, an American cake recipe that satisfies extreme chocolate fiends like me who prefer their chocolate cake moist, rich and intense.  In fact, I’d go so far as to say that it’s one of the best-tasting chocolate cake recipes I’ve tried, along with Jo Wheatley’s chocolate mud cake.  Be warned though, it’s uber-rich, so once you’ve had yourself a hefty wodge of it, you may need a lie-down!

Serves 12-15

Technical notes:
  • This cake is a whopper.  You can bake it in two 10” tins, or you can split it - which is what I did for this post - into three 8” tins plus either two 4” tins or some cupcake cases.
  • I found the sponge to be very reliable; it won’t fall apart on you and it slices easily to allow for frosting. It also stood the test marvellously when I used it for a novelty cake (witness this Cowboy cake, for which I used the recipe in the quantities given to bake two 10” layers which formed the denim jeans tier of the cake. In this instance I sandwiched and frosted the layers with apricot jam and Italian meringue buttercream before covering the cake with further Italian meringue buttercream and sugarpaste).
  • From research and testing, I’ve discovered that if you’re putting oil into a cake and the recipe also calls for buttermilk, you can end up with a rubbery sponge. To get around this, it’s preferable to replace the buttermilk with equal amounts of natural yoghurt (e.g. replace one cup of buttermilk with one cup of yoghurt).  If, however, you’re following a recipe that uses butter rather than oil and then calls for buttermilk, that’s fine, no need to replace the buttermilk with yogurt.
For the cake:
  • 2 tsp instant coffee
  • 360ml (or 1.5 cups) hot water
  • 75g dark chocolate (70% cocoa)
  • 650g caster sugar
  • 375g plain flour
  • 150g cocoa powder
  • 2 tsp baking soda
  • 1 tsp baking powder
  • 1 tsp salt
  • 3 large eggs
  • 180ml vegetable oil
  • 360ml (or 1.5 cups) natural yoghurt
  • 1 tsp vanilla extract
For the chocolate fudge frosting:
  • 400ml double cream
  • 400g chocolate (60% cocoa, or do as I did and use half 50% and half 70%)
  • 3 tbsp golden syrup
  • 100g unsalted butter, softened and cut into cubes

To make the cake
Preheat your oven to 160C.

Grease and line your tins. Depending on the size of cake you wish to go with, this could be either: two 10" tins; or three 8" tins plus two 4" tins (if you don't have 4" tins, you can simply place a few cupcake cases into a muffin tray and bake cupcakes from the spare batter).

Place the coffee and hot water in a small saucepan over a medium heat and stir until the coffee granules have dissolved. Add the chocolate and continue to stir until the chocolate has melted, then take the saucepan off the heat and leave aside to cool. Don't worry if the mixture looks grainy, it will be fine when added to the cake batter.

Sift together the sugar, flour, cocoa powder, baking soda, baking powder and salt. Ideally you should sift these ingredients together three times to ensure they're fully combined and that you've trapped lots of air into them (results in a fluffier cake).

Crack the eggs into a clean bowl and whisk on a high speed until they are thick and pale in colour (this will take a few minutes). I used an electric handheld whisk for the eggs as the attachment from my freestanding mixer wasn't deep enough to reach them. Once they were whisked, I switched to the freestanding mixer, but you can stick to a handheld if you wish.

Add the oil, yoghurt and vanilla to the eggs and whisk on a low speed to combine.  Then add the chocolate and coffee mixture and again whisk gently to combine.

If you have a K-beater/paddle attachment, at this point swap the whisk attachment for the paddle.

Add about half of the sifted dry ingredients into the wet ingredients and beat to combine on a low to medium speed. Once combined, scrape down the sides of the bowl, add the remaining dry ingredients and beat again until thoroughly combined.

If using two 10" tins, divide the batter equally between them then bake at 160C for 10 minutes before reducing the oven temperature to 140C and baking for another 50-55 minutes. The cakes will be done when a knife inserted into the deepest part of them comes out clean.

If using three 8" tins, pour enough batter in each one to fill them to about half way (about 600g of batter in each). Split the remaining batter between the two 4" tins or amongst the cupcake cakes (fill each case to about two-thirds). Bake the three 8" cakes at 160C for 10 minutes, then at 140C for a further 20-25 minutes (or until a knife inserted into the cakes comes out clean). The 4" cakes or cupcakes should be baked at 140C for 20-25 minutes. I baked the smaller cakes separately, after the 8" cakes were done. The batter was fine left to sit unbaked for an hour or so whilst the bigger cakes were baking.

Remove the cakes from the oven and allow them to cool in their tins for 10-15 minutes before turning them out of the tins and allowing to cool on a cooling rack.

To make the frosting
Break the chocolate into small pieces into a heatproof bowl. Add the golden syrup into the same bowl.

Heat the cream in a saucepan over a medium heat until it starts to simmer. At this point, remove from the heat and pour the cream over the chocolate and syrup. Allow to sit for 30 seconds (this lets the heat from the cream start melting the chocolate) before stirring with a whisk or a spatula to combine.

Once the chocolate has completely melted and combined with the cream and syrup to form a glossy ganache, add the cubes of butter and stir again until the butter is melted into the ganache and fully incorporated.

To assemble the cake
If you've baked two 10" cakes, slice each cake in half horizontally using a serrated knife or a cake leveller. If your cakes have a domed top, at this point you can also slice off the dome to ensure you have two flat cakes (just promise me you'll eat the sliced off tops rather than discarding them!)

If you've baked three 8" cakes, you will not need to slice the sponges in half as three layers of sponge is plenty for one cake, but I did slice my additional two 4" sponges in half horizontally.

Place one sponge upside down onto a cake plate, so that the bottom of the cake is facing up. Using a palette knife, spread a thin layer of ganache all over the surface of the sponge.

Place the next layer on top, again upside down, and again spread a layer of ganache all over the surface. Repeat the process until all your layers of cake are stacked on top of one another and each layer has been spread with ganache.

Use the remaining ganache to coat the the sides of the cake (you can add more ganache to the top of the cake too). If you have cupcakes, you can either pipe ganache onto the surface or spread it over with your palette knife.

Refrigerate to set. The cake can be kept in the fridge and removed about two hours before serving, or can be kept in a tin in a cool, dark place.

  1. This cake is as its description states epic. Thought I'd rustle it up as a birthday treat for my colleagues (my birthday but I made the cake!) - it IMHO was the best chocolate cake I've made.

    So this is now my go to fave recipe for chocolate cake.

    Its so moist and light and the ganache (which I thought was a little bitter!) compliments the cake so well.

    Thanks again for a wonderful recipe! Look forward to your next one

    1. Hi Railla, how kind of you to bake a cake for others on your own birthday! Wow, so glad you liked it - I'm inclined to agree that it's an amazing recipe. If the ganache was too bitter for, you could add two to three tablespoons of caster sugar next time (place in the saucepan with the cream to dissolve), or another couple of tablespoons of golden syrup to sweeten it a bit more, but yes, I agree that it complements the cake well :)

  2. This was a really easy recipe to follow Rana, thankyou! I had to slightly adapt the recipe as I only had 50g cocoa so had to use extra dark chocolate and flour. Was still delicious though :)
