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
Yes, you definitely can. The brownies will still be delicious without (might take a couple of minutes less time to bake)
This is likely due to the brownies being over baked, but they can also be over mixed.
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.
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
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.
Yes! You can use all white chocolate, all milk chocolate, all dark chocolate or whatever mix you want folded into the brownie mix.
Triple Chocolate Brownie Recipe
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.
Hi, I tried to make these brownies and even with 40 minutes in the oven they were virtually molten – I followed the recipe to a T so I’m not sure where this went wrong – any advice?
Hey! For them to still be so under done at 40 minutes, you will have to have done something incorrectly. It could be using the wrong ingredient, or not doing the method correctly. Often, it’s because the egg/sugar isn’t whisked up thick enough, and then not folded gently enough. Also, your often may not be the right temp (As often or not, ovens aren’t the temp you think they are.)
These brownies are amazing! And the recipie is so clear and easy to follow. I used to use the nigella recipie but there was always something not quite right. Thanks so much Jane x
When you say 200g dark chocolate, does it need to be cooking chocolate?
Any dark chocolate that is 70% or higher… ideally 80% or more though. I use either cooking chocolate, or supermarket own confectionary chocolate.
After many failed attempts I’ve finally found a brownies recipe that works and with the crackly top! Thank you so much for sharing 😉 so deliciously chocolatey
Is it okay to use self-raising instead of plain flour? what difference would it make? 😀
I really would advise using plain as would don’t want the raising agent!
I am going to make brownies this weekend but with an easter twist, im going to top with chocolate cornflake cake mix. Will these be sturdy enough to hold that density on top do you think if i cook them a little longer or are they too gooey?
Thank you 😊
I think it could potentially work, but it will always be hard to cut as the cornflake cake mix is always going to be more solid than a brownie x
Hi, these look soo good! I was wondering what would happen if I use a semi sweet chocolate with 51% cocoa instead of dark chocolate and just put less sugar? How much mess sugar do you reckon I would need?
I wouldn’t advise messing with the recipe, to be honest… the darker the better for the baking, I use 70% minimum. And the sugar is used to make the mousse, so you need the full amount.
Is it possible to overmix the egg and sugar?
I would say it’s quite hard… eventually it will always be possible. I leave my whisking and quite a high speed for a good few minutes and its fine!
Just made these , they tasted amazing !! Was a bit unsure if I cooked them properly though because the middle and bottom of the brownie was wet/oily looking , they were in my over for 40 mins though .
It might just be that it was a little thin when it went in, so it took a little longer!
Another perfect, easy to follow recipe! Didn’t have a big enough tray but split it into two smaller ones and they came out fab! Love that the measurements for the chocolate are a round number, easy to buy without having random chunks leftover! (Hate dark chocolate so leftovers just get thrown away).
The only problem I have with your blog, is having to decide which of your fab recipes to try next!
Hi Jane !
This recipe looks absolutely exquisite!! I was just wondering, if I keep the brownies for a few day and heat them up when I want to have some (cause I love it warm with a cup of milk) will the chocolate chunks still be gooey and chewy ?
Thank you!
Cheers, Juliette
If the brownies were warmed again, the chocolate chunks will be gooey again!
I made these for the first time yesterday along with the Nutella and Ferrero Rocher cheesecake and omggggggggg they’re both absolutely devine!!! I’m not a baker, I’ve only ever made shortbread biscuits (easiest thing ever) , but I have 2 young daughters and thought I should start learning. I follow you on Insta and you made me realise how straight forward it was to make it all from scratch instead of getting shop bought. I’m immensely proud of myself and your recipes are just beautiful, thank you! X
I need to make 2 lots of these brownies, can I double up on ingredients or would I need to make 2 separate batches? x
It depends – personally I would whip up two batches to make sure I get them right, but if you’re confident then go for it. Just make sure the eggs/sugar mix is really VERY thick and moussey before carrying on, and be as gentle as possible when folding everything together. x
