Chocolate Orange Loaf Cake

Chocolate Orange Loaf Cake

Chocolate and orange are one of my top favourite flavour combinations so I love finding new ways to bake with them. This Chocolate Orange Loaf Cake is an easy to prepare chocolate sponge flavoured with orange extract, it’s baked on a low temperature for around an hour to make sure it doesn’t dry out. I also stirred some chopped up Terry’s Chocolate Orange into the sponge for extra yummyness. I’ve decorated the top with chocolate orange buttercream and slices of Terry’s Chocolate Orange of course!

How to make Chocolate Orange Loaf Cake…

To make the sponge I mixed the butter and sugar together, then whisked in orange extract, eggs and milk. Then I added self raising flour and cocoa powder, and whisked in. I also folded in half a Terry’s Chocolate Orange that I chopped up.

I poured the mixture into my lined loaf tin and baked it for 1 hour.

I made a chocolate orange buttercream and decorated the top of the loaf cake with it.

To make the Chocolate Orange Loaf Cake extra yummy and tempting I decorated it with Terry’s Chocolate Orange pieces and some orange sprinkles! The sponge was perfectly light and moist once sliced, and it was full of that chocolate orange flavour I love so much. If you’re a fellow chocolate orange fan you will love this Chocolate Orange Loaf Cake!

Tips for making the Chocolate Orange Loaf Cake:

  • The cake does need an hour in most ovens, this sounds like a lot, but it’s a very dense cake so baking it on a low temperature for a long time produces the best result.
  • If you can’t get hold of orange extract, you can use the zest of two oranges in the sponge. You can’t replace it with anything in the buttercream unfortunately.
  • Chop the Terry’s Chocolate Orange that goes into the sponge quite small, about the size of a chocolate chip, to avoid sinking.
  • You can freeze the undecorated sponge. Wrap it up well and freeze for up to 3 months.

  1. I agree, chocolate orange is a gorgeous flavour combination. My eldest daughter would devour this. I love the idea of stirring pieces of broken up chocolate orange into the cake batter too.

  2. 5 stars
    This looks absolutely epic! What a fabulous recipe and such a crowd pleaser. I love a Loaf Cake. Great family bakes and perfect for school fairs too. Although I wouldn’t want to let this one go! Thank you so much for sharing it with #CookBlogShare

  3. Chocolate and orange is one of my most favourite combinations ever! I love this cake, which incorporates both my favourite things. 🙂
    I will definitely try this out soon. Bookmarked the recipe.

  4. This looks delicious Kat!! I keep seeing Brits sharing their love for Terry’s chocolate orange but I’ve never tried one! I do love the combination of chocolate and orange tho. This looks SO delicious!!

  5. 5 stars
    oh my that is gorgeous!!! you caught my attention with just the chocolate orange part to be honest! I love the stuff and I love using it in bakes too. This looks very yummy Kat
    Thank you for sharing with #Bakeoftheweek x

  6. Oh my Kat! Now this might even make hubby eat chocolate cake! 😛 What a delicious idea (now I want orange chocolate!) Oh, and you can get whole giant tubes of orange smarties so these might be added to mine too! Thanks for sharing at Fiesta Friday.

  7. Yumm looks a killer. What if i dnt have self raising flour how do i use normal flour and add what to make self raising?

    1. You can use plain flour and add baking powder – I would estimate 1.5 tsp but I haven’t made it this way before. You can buy self raising flour from most supermarkets though 🙂

    The cake was delicious, went down really well
    Thank you for doing this recipe in Metric, virtually every recipe is in Cups and it’s a measuring system which really does my head in.

    1. That’s wonderful to hear Paul, I’m so glad you enjoyed it! I’m not a fan of the cups system either, using weighing scales is so much more accurate 🙂

  9. 5 stars
    Oh my goodness this is incredible! I made it for a friend’s birthday and we absolutely devoured it. Wasn’t sure if an hour would be too much in the oven but it turned out it was absolutely perfect! I added a little more orange extract to the icing to make it more orangey but I bet it would still be delicious without the extra.
    Thank you so much for sharing!

    1. I’m over the moon to hear this Luna, thank you so much for your feedback, I’m thrilled you liked my recipe 😀

  10. I made the Terry’s Chocolate orange loaf cake for our charity bake sale today and it went down a storm! The recipe was super easy, and I had enough mixture left over to make two cupcakes. I also made it at a time when the supermarket were selling the chocolate oranges for 75p! There was plenty of buttercream so next time I would probably do slightly less. It’s inspired me to try some alternatives too! Thanks for a great recipe

    1. Hi Claire, you could freeze it without the buttercream and decoration. I wrap cake in baking paper, then plenty of cling film to ensure it’s wrapped well.

  11. 5 stars
    Amazing! On my second slice already. The buttercream is beautiful, really light and fluffy. I had a slight issue with the chocolate sinking, but I will fix that next time (because I’m definitely making it again!!). Thank you for the recipe.

    1. So glad you enjoyed it Kayleigh! Try cutting the chocolate into smaller pieces next time, I hope that helps!

  12. After reading the comments I feel like an idiot as I wanted to ask what temperature you’re baking the cake at as I can’t see one mentioned. An hour just seems a long time so I feel unsure about taking this on. I’m in the uk so plenty access to a chocolate orange.

    1. Hi, it needs an hour because its a very deep mixture, I bake it at 160C Fan (which is gas mark 3). All ovens are different so if your oven runs hotter then you may need to turn it down, but it definitely needs around an hour. Let me know how it goes!

    This bake is a delicious moist chocolate cake with a hint of orange made even tastier with the addition of chopped up Terry’s chocolate orange. The cake took exactly an hour in my oven and was perfectly baked.

  14. 5 stars
    Oh Whow…..easy to follow recipe, simple to make, and a joy to eat!!??
    Only trouble….they all want more!!

  15. This looks amazing and can’t wait to try! Silly question coming your way but baking a birthday cake for my husband and wanted to use an 8’’ tin. Can I simply use the above quantities or should I adjust them? Thanks.

  16. I can’t wait to make this! Just a quick question, I only have a 0.5lb loaf tin can I still use these exact measurements?

  17. 5 stars
    Great recipe, works really well with orange extract and the cake is really moist, benefitting from the slow bake. I personally halved the buttercream recipe and put this in the middle of the cake and melted chocolate orange over the top – this turned out perfectly.

    1. Thank you so much Neil, I’m so happy you enjoyed it and your decoration sounds yummy!

    1. Hi Kristin, you can find my conversion guide here:

    So tasty! I never normally bake chocolate cakes because I always think they’re a bit dry but I love chocolate orange so wanted to give it a go. Flavour was great, and it was lovely and moist.
    Thanks also for the tip off on clubcard price for chocolate oranges- went to go and get some but they were all gone! Not sure if we shop at the same Tesco in Manchester haha

    1. Hi, yes you can do that! The orange extract will provide a much stronger orange flavour than juice though.

    An hour was WAY too long in the oven for this cake. I resisted the temptation to check it sooner because the recipe stated, more than once, that the cake needs to bake for the full hour.
    My oven is usually spot on for recipes and things sometimes even need to bake a little longer than a recipe states, but this cake came out dry as a bone, burnt on the edges, and crumbly. My son had requested this cake for his birthday, so it was a big disappointment. If I attempt it again, I’ll bake it for a MUCH shorter time!

    1. Hi Christy, I’m sorry the recipe didn’t turn out how you expected. I’m not sure where you have read in my recipe that the cake needs to bake for the full hour. I have stated that it needs an hour in most ovens, or to bake it until a skewer inserted in the centre comes out clean. You know your oven best after all, and the skewer test is the best way to check a cake is done. Can I just check if you used a 2lb loaf tin for this recipe? If you used a shallower or wider tin that would explain why it didn’t need as long to bake. Good luck for next time!

      1. “The cake does need an hour in most ovens, this sounds like a lot, but it’s a very dense cake so baking it on a low temperature for a long time produces the best result.“ is the verbiage I was referring to.
        Yes, I used a 2 lb loaf pan, so that wasn’t the problem. I’ve already decided to try it again and bake it for a shorter time and possibly at 325 degrees instead of 350. Fingers crossed!

        1. Hi Christy, thanks for getting back to me. I’ve had some people question the long baking time, but it does always take an hour in my oven and I’ve had people come back and confirm that it also took an hour in theirs too. It’s so tricky with ovens as they are all so different! Turning the heat down sounds like a great solution, I think this will make a big difference for you. Let me know how it goes!

        2. Hey usually my cakes take an hr to bake as well but mine baked in 55 mins 150 degrees in a fan oven & seemed to burn a little so I covered it with foil in the last 25 mins x

  20. 5 stars
    Came out perfect! Thanks so much for sharing this lovely recipe.

    For icing I just made a smaller quantity as I prefer less icing & instead of orange essence I put in some melted chocolate orange!

    Highly recommend this recipe to everyone xx

    1. Hi Danielle, yes I don’t see why not, if they are similar to the size of cupcakes then 20-25 minutes. Check they are done with a thin skewer inserted in the centre. Let me know how you get on!
