Chewy, gooey, deliciously yummy Terry’s chocolate orange cookie bars. Easy to bake, even easier to eat the entire batch!

Chocolate orange cookie bars

SO, its clear that I love Terry’s chocolate orange. I have oodles of recipes, and no I will never stop. However, I also adore cookie bars. This new fangled way of eating my favourite things… cookies AND Brownie types put together, making cookie traybakes.

My M&M cookie bars and Rolo cookie bars have always been popular ever since they were posted on to my blog. Combining that with my favourite recipe ever, my Terry’s chocolate orange cookies, I knew I had to share them with you all.

Chocolate cookie batter

I LOVE this cookie batter as its so damn good. It’s the perfect chocolate level, baked for the perfect amount of time. You can make them normal cookies rather than chocolate cookies (look at my Oreo cookie bars for example) but for Terry’s chocolate orange, I had to make it a chocolatey base.

Orange flavour

I decided to use orange extract in these bars as well to encourage the orangey flavour, but you can easily use zest as well (I just didn’t have any!). You can always add some extra spare segments on top of the cookie bars in the last couple of minutes of baking, but don’t put them on top right from the beginning, they will just burn (The same as in my Terry’s chocolate orange cookies recipe!).

Good reviews!

I would say my usual right about now, about how my trusty taste testers loved these (which does always happen)… but I didn’t want to share these. I wanted to keep the entire batch to myself, but I wasn’t allowed. About 75% of the cookie bars went with me to my parents house, but I ate the rest myself. There were amazing responses to these delicious beings,  These taste SO GOOD.


I used the normal milk chocolate orange in this recipe but you can find dark and even white chocolate orange in supermarkets nowadays, moreso at Christmas time I find but that may just be my local supermarket. I personally wouldn’t change from the milk chocolate in the recipe however when I do top my cookie bars with a segment, I love the rich kick the dark chocolate orange can bring to the cookie bar.

All the chocolate orange!

You could potentially ask why I bothered posting this recipe, but I found 6 Terry’s chocolate oranges at the back of my cupboard that were going out of date (I know right, shock AND horror) so I just made them. I tend to stock up on chocolate orange around Christmas time as when you fancy some, you can never seem to find it anywhere! 

I also made something else but that is coming soon… Either way, you could say that these are too similar to my Terry’s chocolate orange brownies, but I disagree. The texture is different, but both are amazing. Whichever you fancy, chocolate orange makes it yummy, and I seriously recommend them both. ENJOY!

Author: Jane's Patisserie


  • 200 g plain flour
  • 50 g cocoa powder
  • 1 tsp bicarbonate of soda
  • 1/2 tsp salt
  • 1 tbsp cornflour
  • 115 g unsalted butter
  • 55 g granulated sugar
  • 135 g light brown sugar
  • 1 medium egg
  • 1/2 tsp vanilla extract
  • 1 tsp orange extract (Or Zest of 1 Orange)
  • 2 Terry's chocolate orange (Chopped)


  • Preheat your oven to 190C/170C fan and line a 9x9inch Square Tin with parchment paper, and leave to the side for now.
  • Whisk/mix the plain flour, cocoa powder, bicarbonate, salt and cornflour together so its evenly distributed – leave to the side.
  • In a larger bowl, melt the butter. Add in the two sugars, and whisk for about 2 minutes so the sugar starts to dissolve and the mixture is smooth. Add in the egg, the vanilla and orange, and whisk again briefly until smooth.
  • Add in the dry ingredients, then the chopped chocolate orange pieces, and mix with a spatula until a thick cookie dough is formed.
  • Press the mixture into the bottom of the tin. Bake the traybake in the oven for 18-20 minutes, until the top of the cookie bake looks ‘dry’ and a skewer comes out basically clean, bar a few crumbs.
  • Leave the cookie bake to cool for about 10 minutes, then leave to cool fully on a wire rack. Cut the bake into 4×4 for decent sizes, or 5×5 for smaller ones! Enjoy!


  • This delicious recipe is based on a recipe by crunchy creamy sweet which I have adapted to grams, and swapped up slightly such as by using the chocolate orange.
  • One way to seriously jazz these up is to use the chocolate orange segment selection you can buy as there are many different flavours, but that could be expensive. You could also use dark chocolate oranges, or even just a different chocolate bar entirely.
  • These delicious beings will last in an airtight container for up to 5 days, but honestly, they’ll be eaten before then.
  • My cookie version is here – Terry’s chocolate orange cookies!

    The recipe says 2 chocolate orange does it mean 2 whole chocolate orange or 2 segments

    • Jane's Patisserie on October 27, 2022 at 3:20 pm

      Hiya! This means 2 whole. Hope this helps! x

  2. Jenna on December 29, 2020 at 8:59 pm

    Hi Jane
    Do I have to use cocoa powder? If not do I up my flour to 250g?
    Thanks Jenna x

    Oh my these brownies (and lots of your brownie recipes) are amazing! Always turn out delicious and are a great hit with everyone. I’m known as the ‘brownie lady’ in work as it’s something I make quite often, and always follow your recipes for this. I do say your recipes are foolproof! Thank you Jane xx

    Absolutely amazing recipe, my family loved these. I’ve made a few of your cookie bar recipes but this is the best so far. I was worried they were undercooked when they first came out but they were perfect when cooled.

  5. Aleeza on December 6, 2020 at 5:34 pm

    I made this today but mine turned out quite cakey? I done it for 18 minutes at 160° so lower temp than stated as my oven runs a tiny bit hotter than normal. How can i stop them going cakey next time please? The flavours were lush though!

    • Jane's Patisserie on December 7, 2020 at 3:52 pm

      Sometimes they can be – did you definitely use the correct flour? And what butter did you use? They don’t normally rise too much so they shouldn’t be too cakey at all. x

    • Emily on September 26, 2021 at 10:01 am

      Maybe used a too big of an egg, that sometimes makes them go bit cakey x

    Hi Jane please could you tell me if it’s possible to freeze these once baked? Would you need to reheat once defrosted if so ?

    • Jane's Patisserie on November 12, 2020 at 10:44 am

      Yes they can definitely freeze! They don’t need reheating, but I usually do just because it makes it gooey! X

  7. Sophie on November 6, 2020 at 4:02 pm

    Hi can I use a 7” square tin and keep the amounts or should I use less? And the baking time – how long will I need to leave it in?
    Thank you

    • Jane's Patisserie on November 7, 2020 at 9:29 am

      I would use about half for a 7″ square as that is quite a lot smaller! It would reduce the baking time x

    Hi Jane

    I’ve made these several times now and they are so, so good – they are definitely up there as one of my favourite recipes! Just a couple of quick questions: I have several bars of orange aero in the cupboard – do you think it would work if I used them instead of the Terrys and, if so, would you recommend freezing the pieces first?

    Thank you. x

    • Jane's Patisserie on October 3, 2020 at 8:23 pm

      For aero, yes I would freeze – just because they crumble so easily when mixing into things! x

  9. Maddie on August 30, 2020 at 5:45 pm

    Sorry to ask such a silly question but when you say 2 terrys choc orange chopped do you mean 2 whole choc orange balls chopped and put inside the mix? Just cause there isn’t any grams
    Thanks 😊x

  10. Charly on June 27, 2020 at 4:53 pm

    Hi, anyone have a rough idea of how many syns this would be? Asking for a friend lol

    • Rachael on July 8, 2020 at 6:33 pm

      It’s 20cal per syn so approx 9!

  11. Paige on June 18, 2020 at 12:36 pm

    Hi I don’t have any light brown sugar, I have Demerara sugar, caster and granulated? What would you suggest is best to use instead?

  12. Aileen Moore on June 1, 2020 at 3:54 pm

    Hi Jane! Can’t wait to make this, but I’m needing to make my gluten free, if I’m using gluten free flour etc, will it still be the same amounts? Thanks x

    • Jane's Patisserie on June 2, 2020 at 11:43 am

      Yes it is theoretically just a straight swap – but you need to double check all ingredients (for example, Terry’s has a ‘may contain’ warning!)

  13. Sarah on May 27, 2020 at 11:11 am

    Hi Jane,

    If I were to make these, could I freeze them to bake later? If so would you recommend making the recipe and placing it in the tin to freeze and then defrost and bake?


    • Jane's Patisserie on May 27, 2020 at 6:33 pm

      Hey! Yes you definitely can! You could freeze the dough into the tin, and then maybe remove it and wrap it depending on how long you wanted to wait, but say it was the next day you could definitely leave it in the tin! x

  14. Talia Mordue on May 16, 2020 at 5:11 pm

    Hi I absolutely love following the recipes for what you make. For this I was wondering does it matter if I have cocoa powder I literally cannot get any anywhere. Just wondered if it was essential?

    • Jane's Patisserie on May 16, 2020 at 5:28 pm

      You will need to add in more cocoa powder to cover the weight difference! x

  15. Sunyah on May 6, 2020 at 9:57 am

    I’m planning to make these in next couple of days. I have all the ingredients apart from cornflour. How important is it? Can I just leave it out?
    By the way, I love all your recipes!

    • Jane's Patisserie on May 6, 2020 at 10:11 am

      Yes it can be – it does create a nice texture for the cookie bars which is why it’s in the recipe, but it’s not essential!

  16. Amy on May 2, 2020 at 8:45 am

    Hi Jane,
    I’m looking to make these today, do you leave some extra Terry’s orange to place on top once they’ve baked, or is this after they’ve baked and cooled. If I put them on top and bake them they may burn?

    • Jane's Patisserie on May 2, 2020 at 10:22 am

      I just chop them through and add them into the recipe – but some ovens can run hotter and may singe/burn the chocolate!

  17. Gemma Wright on April 7, 2020 at 7:25 pm

    How deep does the 9×9 inch tin need to be please?

    • Jane's Patisserie on April 7, 2020 at 7:36 pm

      Not very for these – I just use a standard depth tin!

    • Chelsey on July 26, 2020 at 1:20 pm

      Hi Jane, yes I’d like to know the same please. I had a 9inch tin which is 5cm deep, would that work? I’m new to baking so not sure what a standard depth tin is. X

    • Jane's Patisserie on July 26, 2020 at 5:49 pm

      a 9″ square about 5cm deep is fine!

  18. Nas on December 4, 2019 at 11:04 am

    Hi jane, I was just wondering can your cookie bar recipes be made into cookies and if so how long would you bake them for?

    • Jane's Patisserie on December 7, 2019 at 8:35 pm

      I would look at my actual cookie recipes.

  19. Nas on October 29, 2019 at 11:32 pm

    Hi, I was just wanted to ask you I tried you rolo cookie bar it was absolutely amazing. When I was looking at the ingredients for this recipe there is only 250grams of dry ingredients flour, and coco powder
    I was just wandering could this recipe be most moist than the role one as it has less dry ingredients compared to the rolo cookie bar.
    Your recipes are amazing love them.
    Thank you x

    • Jane's Patisserie on October 30, 2019 at 1:26 pm

      The cookies have different recipes, as with cookies that don’t have cocoa powder in work differently. How ‘moist’ a cookie is depends on how long you bake the cookie for, not the recipe x

  20. Jill Lockett on September 28, 2019 at 5:35 pm

    Made these today. Absolutely amazing. I love Terry’s chocolate orange and you make the recipes so easy to achieve. Thank you! X

  21. Lauren on August 1, 2019 at 12:11 pm

    Do you mix both chocolate oranges into the mix or do you leave some for the top? If so, what weight of chocolate orange pieces should go into the mix?

    Thanks 🙂

    • Jane's Patisserie on August 1, 2019 at 5:23 pm

      The bits on top are a part of the weight in the recipe list – but you could add some extra on if you wanted! When making it the mix is quite dry so some bits naturally are on top anyway! x

  22. Faith on March 13, 2017 at 1:17 pm

    Whoa! I love those chocolate oranges. Will definitely save this recipe. Thanks for sharing!

  23. aki bilal on March 13, 2017 at 11:34 am
