A wonderfully soft Chocolate Orange Cake made using fresh oranges, topped with a fudgy chocolate orange ganache frosting. You won’t be able to stop at just one piece!
I’m converted.
Not one to ever pick a chocolate orange dessert, I wasn’t sure how I would go when I decided to develop a recipe for a Chocolate Orange Cake. But I can honestly say, I’m now the BIGGEST fan.
I ate this cake almost every day this week, savouring every last bite of that fudgy choc orange frosting. It’s a fantastic celebration cake or Friday night fave for choc orange lovers everywhere – and those yet to join the bandwagon.
Why you will love this cake
- It’s undeniably choc orange with real fruit flavour.
- You don’t need any weird or hard-to-find ingredients.
- The cake is soft and tender and stays fresh for days.
- The chocolate ganache frosting is HEAVEN and can easily be made ahead of time.
Recipe testing
What I was looking for: A soft and tender chocolate cake infused with real orange flavour, thanks to plenty of orange zest and freshly squeezed orange juice. Cocoa is a strong flavour, so I wanted to make sure when you reached in to take a bite, you knew unmistakably that this was a choc orange cake.
I’ve also recently been testing recipes for chocolate ganache frosting and knew this rich, dark, fudgy frosting would pair beautifully with this cake. Infusing the cream with orange zest is an easy way to add even more flavour to this delicious frosting.
I used my favourite Chocolate Fudge Cake recipe as the starting point for this recipe. It creates a beautifully soft and tender cake, so I made a few tweaks to amp up the orange flavour and was SO happy with the result.
ingredients for the cake
- Butter: Salted or unsalted is fine. If you use unsalted, add a pinch of salt to the dry ingredients. Make sure your butter is softened to room temperature so you can easily beat it together with the sugar, until pale and creamy. This is commonly referred to as ‘creaming.’
- Caster sugar: Caster sugar is a fine white sugar used for baking in Australia. If you don’t have easy access to it, use granulated sugar instead. Read more about caster sugar here.
- Brown sugar: For a little extra flavour, we also add a little brown sugar. Light or dark brown sugar is fine. I typically use light (regular brown sugar in Australia).
- Eggs: Make sure your eggs are at room temperature so they will incorporate easily with the other ingredients.
- Plain flour: Use plain flour or all purpose flour for this recipe.
- Cocoa powder: This recipe calls for regular 100% natural cocoa. It should not be sweetened.
- Baking powder
- Baking soda
- Orange juice and zest: Use fresh oranges – you’ll need approximately three for this recipe.
- Full fat milk: Be sure to use full fat or whole milk for the cake, rather than light or reduced fat milk.
How to make it
- Make sure your butter is softened to room temperature, then start by creaming together the butter and sugars using an electric mixer on medium speed. After a few minutes, your butter should be pale and creamy.
- Add eggs, one at a time, and beat briefly on a low speed until mixture is combined. Your mixture may look at little curdled at this point – that’s ok! Scrape down the sides of the bowl.
- In a separate bowl, add plain flour, cocoa powder, baking powder, baking soda and orange zest and lightly whisk together.
- Then add dry ingredients, along with the freshly squeezed orange juice and milk, to the butter mixture. Mix on a low speed until all the ingredients are combined and you have a creamy chocolate cake batter. Perfect!
- Pour chocolate batter into prepared cake pan and bake for approximately 30-35 minutes or until a skewer inserted into the middle of the cake comes out clean. Leave the cake in pan to cool completely, but place the pan on a cooling rack.
Lets talk frosting
This frosting is truly amazing. It is basically a chocolate ganache, which is what you get when you combine chocolate and cream. But to make it extra special, we infuse the cream with orange zest and also add a little butter for richness. For the best results, start with the best ingredients.
Cream: Be sure to use a high fat (at least 30%) cream for the ganache frosting. Don’t use pre-whipped cream or a light/reduced fat cream. I tested this recipe using thickened cream.
Orange: You’ll need the zest of one orange, finely grated.
Dark chocolate: I recommend using a good quality block of dark or semi sweet chocolate (50-70% cocoa). I use either Nestle Plaistowe dark chocolate or Cadbury Baking dark chocolate for this recipe. Chocolate chips will work but since they are designed to keep their shape when baking, they can take longer to melt. I also prefer to chop a block of chocolate by hand so I’m in control of how fine I want it.
Butter: And a little butter, because butter ❤️ Salted or unsalted is fine.
How to make chocolate ganache
You can make ganache on the stove or in the microwave. For this frosting, I find the stove top method to be the easiest.
- Begin by adding your cream to a medium saucepan and placing it on a low heat. Add orange zest. Stir gently and let it warm up until it’s hot to the touch. You may turn the heat up to medium but DO NOT let the cream come to a boil. Slow and steady wins the race here.
- Add chopped chocolate and continue to stir until all the chocolate melts and ganache is smooth.
- Finally, add butter. Stir until melted. Remove ganache from heat and transfer to a heatproof bowl. Leave to cool at room temperature for 15-30 minutes.
- Cover with plastic wrap and pop in the fridge for 3-4 hours to firm up. I like to stir my ganache every hour to make sure it cools evenly.
- When ganache is thick enough to spread, generously frost the top of your Chocolate Orange Cake.
Frequently asked questions
Yes. This recipe will make two 8 inch cakes or three 6 inch cakes.
Yes you can (although this frosting truly is worth trying!). Check out my Chocolate Buttercream recipe.
Give it time. The frosting will take around 3 hours to thicken – maybe longer depending on your ingredients, how hot the mixture was and the temperature of your fridge. If you are in a hurry, pop it in the freezer. Also make sure you use the right cream – a full fat version please!
Don’t panic. You can either take your ganache out of the fridge and let come back to room temperature or – if you’re in rush – microwave it for 20-30 seconds until it reaches your desired consistency.

Instructions
- Chocolate orange cake
Grease and line the bottom of a quarter sheet pan (9 by 13 inches) with baking or parchment paper. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. - In a large mixing bowl, add butter and sugars and beat with an electric mixer on medium speed until pale and creamy.

Add orange zest and stir while cream is warming and being infused with orange flavour. - Once the cream is warm (but not boiling), add chopped chocolate. Continue to stir while chocolate melts and becomes smooth. Add butter and stir until melted. Ganache should be smooth and glossy.
- Remove chocolate ganache from heat and transfer to a heatproof bowl. Let it cool for 15 minutes and then place it in the fridge for at least 3-4 hours. Give it a stir every hour.
- Once the ganache is thick enough to spread, frost top of cake using a small spatula.
Notes
Cake shape and size: I used a quarter sheet pan (9 by 13 inches) for this recipe. You can use this recipe to make two 8 inch cakes or three 6 inch cakes.
Orange juice: I recommend using freshly squeezed orange juice for maximum flavour. However, if you would like to use bottled orange juice, just make sure it’s 100% orange juice.
Cocoa powder: I tested this recipe with 100% natural cocoa powder – it should not be sweetened.
Cream: Be sure to use a high fat (at least 30%) cream for the ganache frosting. Don’t use pre-whipped cream or light cream. I tested this recipe using thickened cream.
Dark chocolate: I recommend using a good quality block of dark or semi sweet chocolate (50-70% cocoa). I make this recipe using either Nestle Plaistowe dark chocolate or Cadbury Baking dark chocolate.
Ganache frosting: This frosting will take a few hours to chill in the fridge. Time and temperature will turn the ganache from runny to thick and fudgy. Times will vary, so check on your ganache every hour, giving it a quick stir, until it reaches your desired consistency. My ganache takes roughly 3 hours to thicken. You can make it ahead of time but it will continue to harden in the fridge. So you can either, leave it out of the fridge to soften slightly or microwave for 20-30 seconds at a time, until it’s soft enough to work with.
Rakhi says
I just made this and it turned out so beautiful and soft and packed with flavour. Amazing recipe, thank you for sharing! Putting this right down in my go-to recipes book <3
Jessica Holmes says
Yaaay! So glad you loved it Rakhi!
Christine McEwan says
Do you think this size pan would work ok? 3.8cm (H) x 19.5cm (W) x 28.5cm (D)
I made a round cake last time but would like to try square like you’ve made.
Jessica Holmes says
Hi Christine, yes! It’s slightly smaller so the cake batter will be deeper and therefore take longer to cook. But you’ll know it’s ready when a skewer inserted in the middle comes out clean.
Vicky says
I made it and it went PERFECT! It’s been a day already and it’s still just as fluffy and wet as yesterday.
Greetings from Argentina
Jessica Holmes says
Yay! So happy to hear that Vicky!
Kari says
Hey, can I make this into an eggless cake where I follow the exact measurements and just eliminate the eggs?
Jessica Holmes says
Unfortunately not Kari, eggs act as a binding ingredient, while also adding moisture and structure. You could try my Eggless Chocolate Cake recipe instead?
Simona says
I had to chill my cake as where I live ants are practically everywhere… arrrgh
Even after keeping it out it still felt dry and not the same like my earlier batch which was superb
What could go wrong
Jessica Holmes says
Hi Simone, yes unfortunately Cake does tend to go dry in the fridge. I always try keep my cake at room temperature where possible.
Pippa says
My electric mixer packed up during the creaming. I added the liquids after the eggs and then beat them as best I could with a fork, I then added the dry ingredients. My oven took eighteen minutes longer, my wrists are not so good and I had to do all by hand and it looked curdled…but it was great!!!!
Jessica Holmes says
I’m so glad you enjoyed it Pippa!
Jessie says
Hi, I’m wanting to make this cake for an occasion tomorrow. Would you recommend leaving the cake unfrosted at room temperature? Or frost it and then store in the fridge?
Jessica Holmes says
Hi Jessie, yes I find cakes can dry out in the fridge so I try keep them at room temperature. I would keep it covered at room temperature and then just frost it when you’re ready to serve. Hope you enjoy it!
Jessie says
Thank you for the suggestion, the cake turned out so moist even the next 2 days! It was a huge hit, would definitely make again, yum!
Jessica Holmes says
That makes me so happy to hear!
Christine McEwan says
Sooooo delicious and was so easy to make.
Jessica Holmes says
I’m so glad to hear that Christine!
kennys says
It looks delicious. I will make half of the recipe because I only have an 8 inch pan. I will let you know.
Erin says
I used a 9″ pan but there was so much left over Mix and the pan overflowed. Next time will line the pan so it is higher on the sides. Makes a huge mix!
Jessica Holmes says
Hi Erin, yes I’d suggest using two 8 or 9 inch cake pans.
Nadine says
That’s what I love!!
Inshaallah am ginna try it
Donna says
Wow, I can’t wait to give this gorgeous cake 🎂 a go! I love how you make it possible to be a good baker, I did the choc fudge cake and it was so fabulous,
Jessica Holmes says
I’m so glad to hear that Donna! I hope you love this cake too!
DIVYA says
This sounds lovely. I’ve been dreaming of a chocolate orange cake forever and all I could find were complicated orange boiling recipes. Definitely going to try it this week. Do you think this recipe could be halved? I shouldn’t be eating so much cake!
Jessica Holmes says
Hi Divya, excited you are going to try it. I haven’t tried halving it myself but I’m sure it would be ok. Or you could just freeze half – it keeps well!
Louise says
Hi Jess, can I use one 9 1/2 inch tin? Otherwise would two 7 1/2 inch tins be ok? Thanks!
Jessica Holmes says
Hi Louise, I would maybe go with the two 7.5 inch tins – I worry there might be too much batter for the one pan. Hope you love it!
vivaan says
nice
Yesica says
Hi, Jess! I love all of your recipes. Do you think that in this one, orange can be replaced with lemon? Because, you know, I have a lemon tree on my backyard…
Jessica Holmes says
Absolutely! Hope you enjoy it!
Dilyn says
Does the frosting make enough to frost a 2 layer 8in cake or should you double it?
Jessica Holmes says
Yes it does!
Kerrie says
Yummy yummy yummy. Beautiful cake. Recipe is a keeper.
Jessica Holmes says
Yay! So glad you enjoyed it!
