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!

Step by step…

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. ๐Ÿ™‚
    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! ๐Ÿ˜› 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 ๐Ÿ™‚

    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 ๐Ÿ™‚

  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 ๐Ÿ˜€

  10. I made the Terryโ€™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. Itโ€™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 Iโ€™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 youโ€™re baking the cake at as I canโ€™t see one mentioned. An hour just seems a long time so I feel unsure about taking this on. Iโ€™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!

  13. 5 stars
    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 canโ€™t wait to try! Silly question coming your way but baking a birthday cake for my husband and wanted to use an 8โ€™โ€™ tin. Can I simply use the above quantities or should I adjust them? Thanks.

  16. I canโ€™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!
