Back to basics

So, recently (I say recently, it was like August time it started) I decided to start a ‘back to basics‘ series on my blog because as much as I bake all these recipes, and usually, post two a week, they aren’t the most basic. Even down to the flavouring, they aren’t the most basic.

I’m not talking about dumbing down recipes or anything like that, as I like to make mine as easy to follow as possible for anyone of any skill level, but more like posting the recipes that most of my other recipes are based on. I’m not saying all my recipes ever are based on those from the ‘back to basics’ series, but more because I thought I would cover all bases to help you guys out.

Instalments so far 

The first in my series of ‘back to basics’ was my no-bake vanilla cheesecake. I had over SIXTY cheesecake recipes on my blog by the time I posted a delicious, but basic, vanilla cheesecake. It was something that is technically in all of the recipes already on my blog, but the number of people that had been searching for one of my blog every day astounded me.

The second in my series of ‘back to basics’, was my triple chocolate brownies. Similarly to my cheesecakes, but not to the same quantity, I had basically used the same recipe quite a few times, but always put extras in such as Biscoff, or Terry’s chocolate orange. The reactions to both of these recipes were really quite astounding! I genuinely never thought they’d be so popular, but they still are now after months of posting.

So, for the third instalment in the series, I thought I would cover one of the most delicious treats that have ever existed, the chocolate cake. Some of you may think “but you already have a chocolate cake recipe”, and I do… with my chocolate fudge cake, but that’s more an American style recipe and its super gooey, and utterly scrumptious, but definitely requires more ingredients and effort.

Chocolate cake

This beauty is basically a chocolate Victoria sponge. The only difference to the recipe from a classic Victoria sponge is that you remove some quantity of flour, and replace that quantity with cocoa powder. It’s still based on the idea that you have equal quantities of flour, eggs, butter and sugar, which is the base of practically most cakes on this blog, but some of the dry becomes the chocolate.

Often the most simple bakes can be the most delicious, this bake is about simple flavours, simple but effective. Using high quality cocoa powder is key as this will boost the flavour of your sponge, I usually use 100% cocoa powder for that rich, delicious chocolate taste.

Accuracy 

If your oven is definitely at the correct temperature, which most ovens technically aren’t, and you mix the ingredients in the right way, to the correct quantities, there is no reason that this cake should ever fail. With ‘The Great British Bake Off’, they apparently test all of the contestant’s ovens every day, by baking a Victoria sponge, and theoretically, they should all come out identical if the ovens work.

There isn’t too much more to explain about the cake itself, but be accurate when weighing it out. Also, if your bakes never tend to work properly, no matter the recipe, invest in an oven thermometer as it may save it all. In my rented house that I lived in last year, it was FIFTY degrees out. FIFTY. We ended up having to buy a new oven and swap it whilst we lived there as the landlord didn’t understand the significance of this.

Buttercream

For the chocolate buttercream, it’s quite a simple one. You MUST use ACTUAL UNSALTED BUTTER. I mean the kind you find in foil, and that when its fridge cold, is solid. You can use a spread for the cake, but NOT for the buttercream. I might get a few smart arse comments about this as to ‘why not’ but if you want a stable buttercream, that will last no matter the heat outside, use actual unsalted butter.

If its peak summer, and there is a heatwave, you won’t need to add any liquid to the buttercream. Technically, you don’t have to at all if you really do beat your buttercream well enough, but I actually like mine a smidge softer so its easier to pipe, so I usually add between one and two tablespoons of boiling water to smooth it out. But, if the weather is so hot you don’t even want the oven on, this won’t be necessary.

Variations on a basic 

All in all, I have used this recipe technically loads of times on my blog, in my Oreo drip cake for example, but never done a post on a simple chocolate cake before. I personally, prefer using light brown sugar in the sponge because I like the flavour, but either that, caster sugar, or golden caster sugar would work perfectly fine.

This sort of sponge has a really good base for multiple uses, and it’s a hardcore classic that millions of people bake across the world as it’s so simple. I generally find the cake fine as it is, because it’s meant to be simple, but you can always add 100ml buttermilk if you wanted, but if you wanted a denser or richer sponge, I would go for something else such as a fudge cake as they really are so different. 

This sort of sponge is a really good base to cover in fondant if you are decorating, or anything similar. You can also swap up the flavours really easily by adding 1-2tsp of different extracts, such as orange or mint, or just swapping up the flavour of the frosting that you decide to put on top.

Tips and tricks

  • This cake will last at room temperature (not in the fridge as it will go hard) for three days. 
  • The cake will freeze for 3+ months 
  • I use a cake tin, or a cake box to store it. 
  • You can use dark chocolate in place of the cocoa powder if you wish – use 100g for the sponge, and 100g for the buttercream. 
  • If your cake isn’t baked fully, your oven might be at the wrong temperature, or it wasn’t mixed correctly. Keep it in, till a skewer comes out clean, and it’s springy to touch.

Ingredients

Chocolate Cake

  • 300 g unsalted butter
  • 300 g caster sugar/light brown sugar
  • 245 g self raising flour
  • 55 g cocoa powder
  • 6 medium eggs

Chocolate Buttercream

  • 200 g unsalted butter (not baking spread)
  • 400 g icing sugar
  • 50 g cocoa powder

Instructions

For the Cake

  • Preheat your oven to 180ºc/160ºc fan, and line two 8" cake tins with parchment paper. 
  • Beat together your butter and sugar until light and fluffy. 
  • Add in the flour, cocoa powder and eggs, and beat again until combined. 
  • Split evenly between the two tins, and bake in the oven for 28-32 minutes. Sometimes it can take a little longer - don't open before 25 minutes, and be as quick as you can checking with a skewer. 
  • Once baked, leave to cool in the tin for 10 minutes, and then transfer to a wire rack to cool fully. 

For the Chocolate Buttercream

  • Make sure your butter is at room temperature. Don't use a baking spread or margarine.
  • Beat your butter on its own for about a minute, to loosen it up. 
  • Add in the icing sugar gradually, beating in during or in 1/3 at a time. Don't add it all in at once. 
  • Also, add in the cocoa powder, beating in fully. 
  • If it's really very stiff, add in ONE tablespoon of boiling water at a time, beating fully each time, until it becomes smooth and lovely. 

To Decorate

  • Place your first sponge on a plate/cake board, and pipe/spread on half of the buttercream frosting. Add on the second cake, and pipe/spread on the rest of the buttercream.
  • Add on anything you fancy as decoration, I used sprinkles. Enjoy! 

Notes

  • This cake will last at room temperature (not in the fridge as it will go hard) for three days. 
  • I use a cake tin, or a cake box to store it. 
  • You can use dark chocolate in place of the cocoa powder if you wish - use 100g for the sponge, and 100g for the buttercream. 
  • If your cake isn't baked fully, your oven might be at the wrong temperature, or it wasn't mixed correctly. Keep it in, till a skewer comes out clean, and it's springy to touch.

    Hi Jane, how deep do the 8inch cake tins need to be? Thank you!

  2. Jasmine on October 29, 2025 at 11:19 am

    Hi Jane, I would like to make this cake in a 13 inch number 8 silicone mould. Would I need to increase the recipe to 400g for a large cake and if so how much flour/ coco powder ratio should I use? Thanks

    • Carri on January 30, 2026 at 6:19 pm

      Hi,

    Great recipe, perfect chocolate flavour. I’ve used this recipe many times and it’s worked out great every time, thank you. If I wanted to add an extra layer, would I just half the ingredients for the third layer? Thanks

  6. Sarah on August 5, 2025 at 6:18 pm

    Can I add a teaspoon of baking powder?

    • Hope on January 11, 2026 at 6:59 pm

    I’ve never reviewed a recipe before but I need to this time! I’m a fairly seasoned baker but always struggle with chocolate cake for some reason. This was perfect and made a beautiful birthday cake for my 3 year old. In fact I made two! Thank you so much.

  9. Daniella on June 28, 2025 at 3:51 am

    I wasn’t able to half the mix into two tins. Because the mixture was pretty thick so I just made one. I’m guessing it will need to bake for longer now. A bit worried I messed it up.

    • Jane's Patisserie on July 1, 2025 at 8:57 am

      The cake mix will be thick (It’s meant to be!) so yes, it will need longer baking time x



  10. Olivia on June 13, 2025 at 6:55 pm

    Hello!

    I only have 1 x 7” springform cake tin, do I need to make any adjustments to the recipe/baking time? 🙂

    Thank you. X

    Thanks for the good work… I followed all the steps and I must say they were easy especially for new bakers like me. Though the end result was not very perfect, I will definitely try it again

    Hi,
    Could you post the quantities for a 6inch version of this cake please? I never know how much flour to substitute for cocoa so be really good to have a 6 inch version receipe to refer to.
    Thank you!

    • Ella on July 18, 2025 at 1:18 pm

      I made 6inch versions of this last week, I just changed the slices to 7 instead of 14, I had around 220g of mix in each tin. There was some excess after making them but didn’t want to overfill 😊
