Gooey, rich, and super chocolatey triple chocolate brownie recipe!

‘Back to basics’

So, I thought I would start a new series on the blog – ‘Back to Basics’. This is because I have a lot of themed or flavoured bakes on my blog, but some of the actual basics haven’t been covered. I technically have a triple chocolate brownies post on my blog, and these brownies are the exact same, but they’re my Christmas tree brownies. I thought it would be best to do a fresh new post for these beauties!

The ‘Back to Basics’ series will literally cover the basic of baking recipes… traybakes, cakes, cheesecakes etc, but as I was in the mood for a super chocolatey flavour, I thought brownies has the best place to start! Also, my mum has been bugging me for a good while now to make a batch of these, so I thought I would oblige to keep her sweet.

Recipe experimentation

I make my brownies in a particular way, as for years and years I struggled with brownies. There are so many different methods out there, and I often found that they took far too long to bake. As long as the brownies have got hot, the gooeyness doesn’t really matter and its not going to kill you, so no brownies were ever harmed in my experiments.

Often, I used to use a recipe that briefly mixed the butter, eggs and sugar so the mixture itself was completely different, but after trying out a few recipes such as the BBC Good Food recipe, I much preferred the whisking technique.

The whisk method

When you put the whisking technique side by side with a different one, I often find you can even just see the differences. The look, texture and more. I much much MUCH prefer this whisking method.

With this method, you basically whisk together the eggs and sugar to a really thick mousse, and its what gives the brownies their texture. You MUST whisk them for basically a really long time until the mixture is much much paler, thicker, and more than doubled in volume. If you briefly mix, it probably won’t work as well. Also, when you then mix the rest of the ingredients, mix them BY HAND so you don’t deflate the mousse.

Stand/hand mixers

I like 99% of the time use my stand mixer for these kinda thangs, as I find it SO much easier, but I get that not everyone has a stand mixer. You can also use a simple electric hand whisk, and its 100% worth it. If you’re in the UK, you can get a basic hand mixer for under £15, and even cheaper in some other actual shops, and this makes baking so so much easier.

Even with a hand mixer, you can get the texture you want. It might just take a smidge longer, but again… you’re going to save your arm and probably your brownies! It is completely up to you however though! 

Folding

When you fold the melted chocolate/butter, and flour/cocoa powder into your egg mousse mix, you want to be as careful as you can, because if you go and beat it all in you might cause your mixture to be too runny.

I can often get comments saying that peoples brownies are taking far too long to bake, and thats down to the mix. People can say they followed the recipe “to a T” all they like, but something went wrong. It can be down to ingredients, but usually… its the mix with brownies. Too liquid, not mixed enough, etc.

Chocolate

For the actual chocolate chips in the recipe, you can use supermarket own chocolate, cadburys chunks, galaxy etc… but I wouldn’t make them too large. For the ones in the pictures, I used Callebaut chocolate chips because I love them, but equally I often use Tesco’s own chocolate bars that come in at 45p per 100g of chocolate.

This is obviously cheaper than Cadburys which can often be £1 per 100g. HOWEVER… for the base of the brownie mixture, YOU MUST USE DARK CHOCOLATE. 70% OR DARKER. No, you can’t taste it like a chunk of dark chocolate, it just makes it so fudgey and delicious, and it naturally sweets so you do NOT need to worry.

Honestly, these brownies are SO GOOD, so I hope you all love these as much as everyone I know does. Enjoy! And I will be posting another ‘Back to Basics’ soon…! x

Triple Chocolate Brownies!

Gooey, rich, and super chocolatey triple chocolate brownies!
Print Pin Rate
Category: Traybakes
Type: Brownies
Keyword: Chocolate
Prep Time: 10 minutes
Cook Time: 30 minutes
Total Time: 40 minutes
Servings: 16 Pieces
Author: Jane's Patisserie

Ingredients

  • 200 g dark chocolate (70%+ cocoa content)
  • 200 g unsalted butter
  • 3 large eggs (or 4 medium)
  • 275 g caster sugar
  • 100 g plain flour
  • 50 g cocoa powder
  • 100 g white chocolate (Chips/Chunks)
  • 100 g milk chocolate (Chips/Chunks)
  • 100 g dark chocolate (Chips/Chunks)

Instructions

  • Preheat your oven to 180C/160C Fan and line a 9″ square baking tray with parchment paper.
  • Melt together the unsalted butter and dark chocolate in a heatproof bowl over a pan of boiling water, on the microwave for 1-2 minutes until melted. Leave to the side to cool to room temperature!
  • Using an electric whisk/stand mixer, whisk together the eggs & caster sugar for a few minutes until the colour has turned pale, is very mousse like, and is double the original volume of the amount of eggs + sugar! 
  • You will know its done because when you lift the whisk up out of the mix it should leave a trail for a couple of seconds before disappearing!
  • When whisked, pour the cooled chocolate mix over eggs and fold together carefully. It might take some time, but be patient – you don’t want to knock out the air you made up on the previous step!
  • Once completely combined, sift the cocoa powder and plain flour on top of the chocolate mix and then fold together again – still be careful to not knock out the air!
  • Once combined well, fold through the chocolate chips and pour into the prepared tin – bake in the oven for 25-30 minutes! Once baked, leave to cool in the tin completely.

Notes

  • These triple chocolate brownies will last in an airtight container for 1 week!
  • If you find they're a bit hard to cut, stick them in the fridge for an hour and it'll make it a lot easier!
  • If they're not done in the time stated, then stick them in for longer, and cover with foil to prevent burning
  • They should be done when they're slightly wobbling when you shake the tin
  • I use this 9" square tin in this recipe!
  • Recipe updated May 2021 - flour used to be 90, cocoa powder used to be 35g. Both recipes work, I just much prefer the increased flour/cocoa. 

 

ENJOY!

    Mid making brownies and have no coco powder? What can I use instead? I have Cadbury hot chocolate powder 🙈 not sure if that would work.

    • Jane's Patisserie on November 29, 2022 at 3:42 pm

      Hiya! Try upping the flour to replace it. Hope this helps! x



    • Kayla on May 14, 2025 at 9:27 am

      Hey did you manage to make these without cocoa powder? I currently dont have any either and wanting to make some

    I always choose brownies for a pudding wherever I go. I always choose brownies if buying from a shop to take away. I LOVE brownies. I’ve tried different recipes and they have been good. But, this recipe, OMG. I am obsessed. This is just the best. I made them again 2 days ago using using Sainsbury’s own brand 200g chocolate bar (£1) and their own choc chips. It’s the most perfect brownie I have tasted in my life! Jane’s recipes have now overtaken everywhere else… no longer is BBC my go-to recipe finder. Just got to now master the blondie…

  3. Amie on September 29, 2022 at 1:34 pm

    White caster or golden? Or a mix?

    • Jane's Patisserie on October 6, 2022 at 3:53 pm

      Hiya! I use white caste. Hope this helps! x



  4. Holly on July 18, 2022 at 12:27 pm

    Hi Jane,

    We are currently baking brownies on possibly the hottest day ever (37 degrees) We have accidently used out of date flour, is this okay or should we quit now?

    Thanks!

    • Jane's Patisserie on July 26, 2022 at 2:37 pm

      Hiya! You should be fine – how did they turn out?! x



  5. Faith on July 11, 2022 at 12:47 pm

    Hi,
    Really need some help! Please Would I be able to use this recipe in 2 – 5×7 inch tin? Would it make two. Many Thanks

    • Cristina on August 2, 2022 at 9:18 pm

      I’m not Jane but I usually calculate the area of a baking tin if I’m changing size. 9×9 in the recipe is 81 square inches. 5×7 is 35 square inches, so times two would be 70 square inches. You’d have taller brownies but it is similar. You would also want to check them for doneness at least 5 minutes earlier.

    It looks awesome. Thank you for sharing this recipe.

  7. Daw on June 1, 2022 at 11:00 am

    I have made these brownies over 20 times and they are always a hit(currently have a batch in the oven)! We’ve made them with choc chips, broken choc, and Easter eggs. Also once I didn’t have enough eggs and so I added a bit of full fat milk and they were still awesome. Thank you!

    • Rebecca on July 7, 2022 at 1:01 pm

      Do you need to add the chocolate in them? Or can you leave the chunks out?



    • Jane's Patisserie on July 8, 2022 at 10:36 am

      Hiya! I f you’d like plain brownies – you can leave the chocolate chips out! Hope this helps! x



  8. Kay on May 23, 2022 at 6:00 pm

    Hi Jane,

    Which cocoa powder would you recommend?

    • Jane's Patisserie on May 25, 2022 at 10:48 am

      Hiya! Take a look at my amazon shop – its linked on there! Hope this helps! x



  9. Lorraine on May 19, 2022 at 7:47 pm

    Would I be able to add banana to this recipe? And would I need to remove any eggs? Thank you

      Can I make these with milk chocolate? Instead of dark thankyou



  10. Aysha on April 30, 2022 at 1:37 pm

    Hi Jayne,
    I absolutely LOVE these brownies, I make them all the time and they’re incredible.
    If I wanted to make them thicker eg I use 1.5x recipe (same tin size) would I need to lower the oven temp and cook for longer ?

  11. Rose on March 30, 2022 at 6:26 pm

    Hi!
    I’ve made these brownies loads of times before and always a hit but I want to add macadamia nuts, will they dry them out or do I need to adapt the rest of the recipe at all?
    Thanks

    • Jane's Patisserie on April 6, 2022 at 2:43 pm

      Yes absolutely you can add them in without adapting – sounds yummy! Enjoy! x



    • Ann-Marie on December 6, 2024 at 5:32 pm

      Hi, how did these turn out? I wanted to add nuts as
      well, what quantity did you use and did you reduce the amount of chocolate chips?

      Thanks



  12. Rebecca on March 26, 2022 at 12:53 pm

    Hi I’ve only got a 8” square tin, Will I need to tweek the time and temperature? Thanks xx

      I have some 100% chocolate, would this be too intense and need balancing out?



    • Jane's Patisserie on December 27, 2023 at 1:21 pm

      If you like dark chocolate, no, if you’re not as big a fan you could add vanilla extract to being sweetness x



  13. Catie on February 3, 2022 at 1:03 pm

    It doesn’t say when to put the chocolate chips in?

    • Jane's Patisserie on February 3, 2022 at 1:39 pm

      Hiya! Take a look at step 7 on the recipe – it says to fold in you chocolate chips once your mixture is combined well! Hope this helps! x

      I made these brownies for my work colleagues and they went down extremely well! They got snapped up so quickly and received really good reviews. One of my colleagues used to be a pastry chef and work in a fancy bakery and she said they were even nicer than the brownies they sold there! So I recommend giving these brownies a try!!



  14. Steph on January 16, 2022 at 5:22 pm

    Hi Jane, these look AMAZING ! What is the difference between a large and medium egg? I’m assuming there is a weight difference but im not sure what that is?

  15. Amy on January 15, 2022 at 3:59 pm

    Hi
    Such a great recipe but how would I adjust this for a heart 8” tin? Wanting to make something for next month.

    Thanks
