If you are looking for the ultimate triple chocolate brownie recipe, then these rich, indulgent and delicious brownies are the ones to bake. Packed with triple chocolate chunks, and with the perfect balance of chocolate throughout, these brownies have the delicious fudgy texture every baker is after. 

Whether you are baking for birthdays, afternoon treats, a family gathering, or simply trying to satisfy a chocolate craving, this recipe is the one you will turn to again and again. 

Note’s from The Patisserie

I have made these brownies well over five hundred times now, in this base form and with extra flavours throughout, so I feel like somewhat of an expert now. They are thick, fudgy and I have tested this recipe over and over to try and produce the best brownie ever… 

  • Deep chocolate flavour from a dark chocolate base
  • Three chocolates folded through for extra indulgence 
  • Easy to follow method
  • Perfect for freezing and making ahead 
  • Soft, gooey and fudgy texture all in one 
  • Great for bake sales, parties, and for use as a base brownie for other flavours

This recipe is part of a ‘back to basics’ series on my blog where I am trying to provide as much information on the basics of baking, to make you a better bake. I firmly believe that once you crack the basics, you can have a lot more fun with baking.

Ingredient notes + tips  

The chocolate in the base 

This recipe has the best flavour balance, but it does use dark chocolate in the base. This ingredient is particularly important for a few reasons. The higher cocoa solids (I would always recommend 70% dark chocolate or higher) helps create a rich chocolate flavour, but it also has naturally less sugar and milk in the chocolate. 

Dark chocolate works best in the brownie base because it creates a richer chocolate flavour and helps achieve that classic fudgy texture. With a higher cocoa content and less added sugar than milk chocolate, it provides a deeper taste and balances the sweetness of the brownie mixture, and with the addition of the rest of the ingredients, provides the best base.

Personally, I would recommend using cooking chocolate such as this one, or using a basic chocolate from the shop. You do not need to use a fancy brand of chocolate for the base mixture.

The rest of the ingredients:

  • Butter – I would recommend using block unsalted butter for the base of a brownie, or a baking spread. Generally, block butter may likely create a better set compared to a spread due to it’s less process nature. 
  • Sugar – You can use caster sugar, golden caster sugar, light brown soft sugar or even dark brown soft sugar. For a basic triple chocolate, I usually use white caster sugar. 
  • Eggs – to make it slightly easier, this recipe is formulated to use four medium eggs, or three large eggs. 
  • Flour – it’s important to use plain flour with no raising agent in it – if you use self raising flour, it will cause a cake texture. If you don’t have plain flour, it may also be known as all-purpose flour
  • Cocoa – I would ALWAYS recommend using a good quality cocoa, with a high cocoa percentage. I would suggest not using a hot chocolate powder as they are mainly sugar and not cocoa. 

Tops tips to making the best brownies

The method behind making these brownies, other than the importance of the chocolate base, is what makes these brownies brilliant and the wonderful texture that they have. Make sure to check out the full recipe and method in the recipe card

Whisking the eggs and the sugar

One of the most important steps in making perfect homemade brownies is whisking the eggs and sugar correctly. This stage creates a thick, mousse-like mixture that forms the foundation of the brownie texture.

You need to whisk the eggs and sugar for several minutes until the mixture becomes:

  • Noticeably paler in colour
  • Thick and mousse-like
  • More than doubled in volume

Do not rush this step. A quick mix simply won’t create the same result, and skipping proper whisking can affect the final texture of your brownies. It’s easier to use a stand mixer or hand mixer because they are quickly, but you do not need to. You just need to whisk for quite a bit longer by hand to get the same texture 

Folding the ingredients together

Once your egg mixture has reached the correct mousse-like consistency, gently fold in the melted chocolate and butter mixture, followed by the flour and cocoa powder. This stage should always be done by hand.

Mixing too aggressively can deflate the air you’ve created during whisking, leaving you with a thinner batter and affecting the final brownie texture. So, make sure to fold slowly and carefully in a figure of eight pattern, keep as much air in the mixture as possible, and avoid over mixing. 

Using the correct tin and oven setting

As well as making sure to use the correct ingredients, following the top tips above, it is so important to use the correct size tin. I use a 9” square metal tin for my brownies, and for the best results, it’s important to use this too. 

Using a smaller tin can cause problems with the bake as the volume difference is much larger than people may realise. An 8” square tin is roughly 25% smaller in volume, and a 7” square tin is 50% less. Also, using silicone or glass or ceramic instead of metal can cause a problem due to how they conduct heat in the oven. 

I always bake brownies on the fan setting in my fan oven, so I bake at 160ºc. I bake them for 25 minutes on the dot as I know my oven well, and when the 25 minutes is up, there is a small wobble in the middle. 

As ovens vary SO much, even if you think they are all set to ‘the same’ setting, there is a very high chance they are not. Timings can therefore vary, so keep an eye on them and adjust accordingly. 

FAQs

Can I leave out the chocolate chunks?

Yes, you definitely can. The brownies will still be delicious without (might take a couple of minutes less time to bake)

Why did my brownies turn out cakey?

This is likely due to the brownies being over baked, but they can also be over mixed.

Can I add a flavouring to these?

Definitely! You can add in flavour extracts really easily when folding in the chocolate/butter mixture to the eggs and sugar. I would use 1-2 tsps of a strong extract such as vanilla, orange or mint.

Can I eat these warm?

Yes, but they won’t have set yet so if they are cut warm, they may still be very gooey. They are still fine to eat, but generally we recommend setting the brownies fully, and the warming a piece through in the microwave if you have one

My brownies sank whilst cooling? what happened?

Brownies do naturally sink slightly when cooling, but if they have sunk a lot it could be due to adding too much air into the eggs and sugar at the start, under baking the brownies, or opening the oven door too early to check on them.

Can I use all white chocolate chips?

Yes! You can use all white chocolate, all milk chocolate, all dark chocolate or whatever mix you want folded into the brownie mix.

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 180ºc/160ºc 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 for 5-10 minutes
  • In a new bowl, 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
  • 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.
  • Once completely combined, add the cocoa powder and plain flour on top of the chocolate mix and then fold together again
  • Once combined well, fold through the chocolate chips and pour into the prepared tin
  • Bake in the oven for 25-30+ minutes until there is a small wobble in the middle.
  • Once baked, leave to cool in the tin completely. The, set the the brownies in the fridge for 3+ hours for best results.

Notes

  • These brownies will last for up to one week in the fridge or at room temperature on a cool day
  • These brownies can freeze for 3+ months 
  • I use this 9″ square tin in this recipe

Storage and Freezing

These brownies are great as they do last really well. As well as being delicious on the day of baking, they also last for up to a week either at room temperature on a cooler day, but also in the fridge. I prefer mine in the fridge, as it keeps the fudge texture.

These brownies will also last for 3+ months, in the freezer. I would recommend letting the brownies bake and cool fully, and then portioning before freezing.

    Could I use an 8 inch tin?

    Hi Jane, hope you are well😊 I absolutely love this recipe and use it religiously but I’m wanting to make some Easter themed brownies using mini eggs. Would it be possible to substitute the chocolate chunks for mini eggs with this recipe or is there another one of your brownie recipes you think would be better suited to to using mini eggs? Thank you!!

  3. Claire on March 18, 2021 at 6:27 pm

    Hi can I use an 8inch square tin for this and if so do I cook it longer thanks xx

    • Jane's Patisserie on March 27, 2021 at 2:05 pm

      Hello! Ideally you would use a 9 inch for the best results but you can try it and yes baking time will increase slightly x



  4. Evie on March 17, 2021 at 9:18 pm

    Hello! I was wondering how long roughly you would usually whisk these for? I made your Bailey’s Brownies before (absolutely INCREDIBLE) and even after mixing with a hand whisk on full blast for about half an hour, although the mixture had increased in size and thickened, I definitely wouldn’t say it had doubled in volume or was a mousse consistency! Was just wondering whether it needs to be a lot longer than that. 🙂 Thank you so much!!

    • Jane's Patisserie on March 17, 2021 at 9:21 pm

      Half an hour probably means its been over done as it really shouldn’t take that long at all!

      Absolutely ❤ these although they take ages to bake. I’ve read through others comments and notice the problem may be the dark chocolate for the base. Can you advise what one is best to use. I’ve used Cadburys dark so maybe thats the reason why they take so long to bake.



    • Jane's Patisserie on April 13, 2021 at 8:32 pm

      You need to use one that is 70%+ cocoa content and unfortunately the Cadbury’s one isn’t!! x



  5. Kathy on March 16, 2021 at 12:26 pm

    Hi Jane,
    Your recipes are by far the best. I use your base brownie mix and add different flavours. However I’m just wondering can you use white granulated sugar instead of light brown and Stork or a cake spread instead of unsalted butter?
    Also I’ve found that the recipe halved fits a 8” round tin perfectly but I’m hit and miss with the bake time. What would you recommend?
    Thank you. X

    • Jane's Patisserie on March 23, 2021 at 3:24 pm

      I would recommend caster sugar instead of white granulated! And stork can be used yes!



  6. Mia on March 15, 2021 at 2:07 pm

    Hi Jane! I’m looking to make these soon but I want to add marvellous creation instead of chocolate chunks or add the ingredients of marvellous creations into the brownie (the popping candy, jelly beans and chocolate beans etc.) separately. Would this work and which way would you suggest doing it?

    • Jane's Patisserie on March 23, 2021 at 3:18 pm

      So some ingredients such as the popping candy and jelly beans etc may be best to add on at the end for decoration, but otherwise I’d say its worth a go!



  7. Maleeha on March 12, 2021 at 11:35 am

    Hi Jane, hope your well. If I was to make this brownie recipe in a 9/10inch round tin, and make a ‘brownie cake’ would this work? Would I potentially need to do anything different?

    • Jane's Patisserie on March 15, 2021 at 12:57 pm

      Hello! A 9 inch square tin is equal to a 10 inch round so that would be the best to use as its a straight swap!x

    Made this today and tasted amazing thank you

  9. Cathy Morgan on March 7, 2021 at 1:25 pm

    We absolutely love these brownies in our house. It’s my sons birthday coming up and was wondering could I possibly use this recipe and make cupcake brownies instead of a tray?
    Thanks a mill xx

    • Jane's Patisserie on March 8, 2021 at 7:50 pm

      Yeah you can do!! They’d take about 20 minutes to bake x



  10. Kirsty on March 6, 2021 at 5:40 pm

    Can you use salted butter instead of unsalted without it altering the taste?

  11. Beccy on March 5, 2021 at 7:57 am

    Hi Jane ,
    Are the brownies able to be frozen ?

  12. Resh on March 5, 2021 at 1:35 am

    Hi Jane,
    I tried these brownies at 160 fan but they seemed to take ages to bake. I made sure that the eggs doubled in size etc. Where could I have gone wrong? Do you use a fan oven, and if so, what shelf so you tend to bake your brownies on?
    Thanks in advance!

    • Jane's Patisserie on March 6, 2021 at 7:06 pm

      What chocolate did you use for the base brownie?

      Could I use hot chocolate instead of cocoa powder? Trying to avoid heading to the shop; but desperate to make some of these today.



    • Jane's Patisserie on March 14, 2021 at 9:07 pm

      It really really depends on the hot chocolate – I only use whittard hot chocolate for baking and that works as supermarket ones dont really work! x
