My 28th Birthday Cake!

A recipe for my 28th Birthday Cake… Chocolate Cake, Chocolate Buttercream, Chocolate Orange Ganache and more!

Today (20th October) is my birthday… and this year, I am 28! It’s been a strange old year for everyone, but it definitely feels strange that it is my birthday again already! It genuinely feels like it’s only been a few months since I turned 27. 

Anyway… I decided to bake my own birthday cake again (because I do basically every year), but also I know you guys love my birthday cake posts! This year I went for a chocolate and chocolate orange themed cake, sort of using up what I had in the cupboards, and making it up as I went a long!

It’s fairly similar to my 27th birthday cake from last year, but also my the bottom tier of my two-tiered celebration cake! I am an absolute creature of habit when it comes to baking cake, and with the limited edition white chocolate orange out at the moment I wanted to incorporate them somehow! 

I went for a chocolate cake this year… as always. I use two of these 8″ tins when I bake deeper cakes, and I just love them! The mix does sound like a lot, because it is… a 500g/10 egg mix is massive, but as it’s split into two tins, and then each cake split into two it makes sense. Four layer cakes need a lot of mix!

If you wanted to just bake a smaller version, you can half the recipe to a 250g/5 egg mix, bake into one tin, and split that into two. It’s much smaller, but might fit the smaller gatherings that are required at the moment in the world!! 

For the chocolate buttercream, I used BLOCK BUTTER. I will say this here, like I have said so many times before… that you must not use a baking spread for buttercream. It’s too soft, and just doesn’t work! For the filling, crumb coat and topping you want a lovely firm buttercream. 

When it’s colder weather, like it is now, I do tend to use 1-2tbsp of boiling water just to soften the buttercream, but in the middle of the summer I wouldn’t bother as the temperature in the kitchen is warmer! I hope that makes sense… but if you make a lot of cakes, you’ll know what I mean. 

For the ganache, it was the same idea as my other cakes, but again I used a mix of dark chocolate and milk chocolate. It’s a lighter colour than you may think as it’s a whipped ganache – you melt the mixture together, and let it sit until it reaches the peanut butter consistency.

You can use it at this point, or you can whip it up with an electric whisk and it makes it a beautiful lovely fluffy mousse texture that is a wonder to work with on the crumb coated cake! I use a small angled spatula when putting on my buttercream and ganache, and a large metal scraper to smooth it over! 

This year, I decided to press some sprinkles I had into the bottom part of the cake for a new style that I haven’t posted on my blog before – and I love it! Before chilling the cake in the fridge, lightly press the sprinkles onto the cake, and then chill to set them in. 

For the drip, I just used melted white chocolate. I didn’t mind that it sets firmer than a ganache.. but you can make a ganache if you want. Use 150g white chocolate, and 50ml double cream, melt together until smooth and drip! Or, add 1/2tsp vegetable oil and stir through. 

Finally, I decorated the top of the cake using my favourite 2d closed star piping tip with some leftover buttercream, some white chocolate orange segments, and some sprinkles!! If you give the cake a go, let me know! Any questions, leave them below! x

8" Chocolate Cake

  • 500 g Unsalted Butter/Stork
  • 500 g Light Brown Sugar
  • 400 g Self Raising Flour
  • 100 g Cocoa Powder
  • 10 Medium Eggs

Chocolate Buttercream

  • 300 g Unsalted Butter (not stork) (room temp)
  • 500 g Icing Sugar
  • 75 g Cocoa Powder


  • 200 g Dark Chocolate Orange (chopped)
  • 150 g Milk Chocolate Orange (chopped)
  • 300 ml Double Cream


  • 150 g White Chocolate


  • Leftover Buttercream
  • Sprinkles
  • Chocolate Orange Segments


For the 8" Chocolate Cake!

  • Preheat your oven to 170C/150C Fan, and line two 8"/20cm deep cake tins with parchment paper.
  • Add the butter and sugar to a bowl, and beat till light and fluffy.
  • Add in the flour, cocoa powder and eggs and beat again until a lovely smooth cake mixture is formed.
  • Split evenly between the two tins and bake in the oven for 50-60 minutes (or until a skewer comes out clean!)
  • Once baked, leave to cool in the tin for 10 minutes, and then leave to cool fully on a wire rack.

Chocolate Buttercream

  • Beat the unsalted butter on its own for a while in your mixer until its smooth and supple.
  • Add in your icing sugar and cocoa powder a little at a time and beat fully until its light and fluffy!
  • (If the mixture is really stiff, add in 1-2tbsp of boiling water and beat fully to smooth out)

For the Ganache

  • Add the the dark chocolate orange and milk chocolate orange to a large bowl.
  • Add the cream to a pan and heat till just before boiling point. Pour over chocolate and leave to sit for 5 minutes. Once sat, mix until smooth (Add back to the pan if its not quite melted).
  • Leave the ganache in a bowl and stir every few minutes until it forms a peanut butter like consistency - you can do this in the fridge as well, just make sure to stir it so it doesn't set too quickly!
  • Whip the ganache with an electric whisk until it is fluffy, light and mousse like!


  • Level the cakes off if necessary. Split the two cakes into two so you have four layers in total.
  • Add your first cake to a cake board (I use a large 10" cake board) and secure with a small amount of buttercream.
  • Spread some chocolate buttercream onto the first layer, add the second sponge. Repeat until you reach the top layer of cake.
  • Spread some chocolate buttercream around the sides to fill in the gaps and create a crumb coat. Refrigerate the cake for at least 30 minutes.
  • Once refrigerated and the ganache is ready, using an angled spatula, slather over the chocolate ganache and then smooth around using a large metal scraper.
  • Carefully press some sprinkles into the bottom of the cake (like shown in the photos)!
  • Once the sprinkles are on the cake, refrigerate the cake for another 30 minutes.


  • Melt the white chocolate until smooth. Carefully drip down the sides of the cake, and fill in the top of the cake with the chocolate!


  • Pipe some swirls of the leftover buttercream on top using a Medium 2D Closed Star Piping Tip and decorate with the sprinkles and chocolate orange segments on top!


  • You can swap the chocolate orange chocolates for a plain dark chocolate and a plain milk chocolate - I just love chocolate orange! 
  • You cannot swap the dark for just milk though - please use what is written in the recipe!
  • This cake will last for 3-4 days once made.

    I want to try this with pink drip – how would you go about colouring the drip? Would you just add colour to the melted white chocolate, if so any recommendations for colour?

    • Jane's Patisserie
      January 8, 2021 at 5:57 pm

      Theoretically yes – but you do NOT want to use a water based colouring as that will kill the chocolate. I like brands such as coloursplash, sugar flair, wilton etc x

    Hey, I’m going to use this recipe to make my sons birthday cake and I was wondering how you evenly distribute the cake mix in to the cake tins? Also what do you use to cut the cakes in half to make it 4? Thank you.

    • Jane's Patisserie
      January 7, 2021 at 1:53 pm

      You can weigh it in, or spoon it in – anything that splits a mixture works! And you can use a knife or a cake leveller x

    Hi Jane!

    I am baking this this week for my mums birthday as a surprise. I saw you commented above about somebody using buttercream on the outside rather than ganache, and i think i will too go for this option. My question is, will the white choc drips still be ok to fall down the buttercream rather than ganache or will it be a mess?

    Thank you!! xx

    Hi Jane,

    Happy New Year’s Eve!

    It’s my boyfriend’s birthday next month and I’ve been thinking of giving this cake a shot! It’ll be the first layer cake I ever bake, so fingers crossed I manage okay!

    I was wondering, would you have any suggestions for if I wanted to incorporate peanut butter into the buttercream?

    • Jane's Patisserie
      December 31, 2020 at 6:56 pm

      Ahh yay! I think just adding in some peanut butter would be fine – say you are making the 8″ maybe add in 200g? x

    Hello 🙂 this cake looks amazing, absolutely adore your recipes! hoping to make it for my own birthday next week however the tier system means it’ll be just me and my fiancé on the day, to make a smaller cake am I just halving all the ingredients (ganache and buttercream too) and using one tin please? xx

    • Jane's Patisserie
      December 31, 2020 at 4:14 pm

      Yes – halving is just the easiest way – and you can freeze leftover slices of cake for the future! X

    Hi, looks great – will this work with gluten free flour? Hoping to make it for my friends birthday but she can’t have gluten! Thanks! X

    • Jane's Patisserie
      December 31, 2020 at 3:59 pm

      Yes it can, but I find it is best to also use xantham gum (unless the GF flour you use already has it in) so the texture is better! Also though Terry’s chocolate orange have a may contain gluten warning so best to check with your friend about that x

    Hey! I’ve just made this for my mums birthday and I can’t wait to try it.
    I really struggled to get my ganache to spread smoothly even using a large cake scraper, any tips?

    • Jane's Patisserie
      December 20, 2020 at 9:20 am

      It is unfortunately just a matter of practice – and getting the ganache consistency correct! Usually I find people try and use the ganache too soft x

    Hey Jane

    I’m making this case today for my brothers 30th – wish me luck 🙂

    If I cut the cake into slices – can I freeze them? Conscious we aren’t going to get through this between us haha.

    Thanks x

    • Jane's Patisserie
      December 18, 2020 at 9:54 am

      Yes you can – it’s best to wrap each slice well in clingfilm!

    Hi Jane,

    Happy birthday! Can I use melted white chocolate orange for the drip? If so would you recommend adding cream, or just melt the chocolate?

  • Emma
    December 13, 2020 at 6:35 pm

    Hey Jane how do you cut the cakes in half. I would be afraid I wouldn’t cut them even. Or could i just leave it as a two layer cake. Thanks

    • Jane's Patisserie
      December 14, 2020 at 10:33 am

      The best way is to use a cake leveler as it is designed for it, but you can also mark the sides with a small cut from a knife and go round carefully! It just takes practice. You can leave it as just two layers but the cakes will be very chunky obviously haha!

    Hiya Jane! I’ve made this cake before and it was DELISH! I’m wanting to make it again but as a 4 layer 6inch cake? I have the PME 6″ by 4″ cake tins, how should I change the recipe should I just use 2/3rds of the recipe? and Would the baking time for each layer be around 30/40 minutes?

    Thankyou so much! xx

    Hi can I use just milk chocolate for the ganache? I don’t like dark chocolate

    • Jane's Patisserie
      November 2, 2020 at 8:57 pm

      Unfortunately not – the ratio of cream to chocolate is different so it’s not a straight swap. You need a 2:1 ratio instead of what’s on the recipe!

  • Sarah Mansley
    October 30, 2020 at 9:28 am

    Hi Jane did you use buttercream and ganache around the cake? I’m confused as to use one or the other and what goes on first. Thank you xx

    • Jane's Patisserie
      October 30, 2020 at 9:31 am

      Buttercream fills the cake and does the crumb coat, and then ganache goes around the outside to finish it. x

  • Sarah
    October 28, 2020 at 2:01 pm

    Hi Jane

    Me again, but if I wanted to put Terry’s chocolate( melted chocolate) in the butter cream how much do I put in? Thank you in advance x

    • Jane's Patisserie
      October 30, 2020 at 9:40 am

      I would add maybe 250g – I much prefer to add the dark chocolate one!

    Hi Jane,

    If I wanted to do the butter cream round the cake instead of ganache, what would the measurements be? Shall I just double it? Amazing cake by the way, I’m a big Fan x

    Anyway, I plan on making this cake and turning it into a pinata cake for my little man’s 3rd birthday. I only have 20cm tins that are 3 inches deep, would they be OK? Or do they need to be 4 inches deep like the ones you use?
    Thank you for your fab recipes. ❤️

      October 21, 2020 at 11:33 am

      Follow my Biscoff Drip Cake for a white chocolate one – as long as you do a crumb coat and put the ganache on it won’t show through! x
