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)

- 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 Jane,
Would light brown sugar work in this recipe instead of caster sugar?
Thanks
Yes it will!!
OMG!!
They look so good!
Cant wait to try them!!!
Hey Jane! I was just wondering if I can melt the butter and dark chocolate on a hob or if I have to melt it in the microwave, I’m doing this for a cookery exam and I’m not sure if the classroom has a microwave. Thanks.
Yes you can melt in a pan!
Hi Jane,
I’ve been searching for the perfect brownie recipe for so long and absolutely adore this recipe however the last few times it hasn’t had the lovely mirrored cracked top do you know what can cause this?
Thank you!
Hey! I am so glad you love it! Unfortunately I can’t help with that, I am unsure!!xx
Hello Jane.
I loooove love this receipe. Hands down the best one I came across. I wanted to bake them 10 inch or 12 inches square trays.
But I dont want them to be too thin do you think I should make 1 and 1/2 batter for the 10 inch? And double for the 12 inch?? I like to keep the thickness of the 9 inch tray. Please advice, thank you x.
Hey! Ahh thank you so much this makes me so happy! I genuinely would try to stick to the correct size tin as I don’t think a 12 inch tray won’t bake properly at all because of the size unfortunately xx
Hi Jane, great recipe! Just wondering how long these brownies last once defrosted? Also if I am freezing the whole batch, should I cut them into pieces before freezing or freeze as a whole slab and then slice them? Thanks! x
Hey! I would recommend freezing as slices and they should last 4-5+ days once de-frosted xx
Hi interested to know how you wrapped and stored them to freeze? Did you defrost them in the fridge or worktop? Did they stay the same quality once defrosted? Thank you x
First attempt at Brownies and they were a HIT!!! Fab recipe thank you !!!
There is absolutely nothing basic about this recipe!! I bought a 9 inch tin just to make these and it was sooo worth it. There is more chocolate in here than I have baked with before and it was amazing. These are the most deliciously fudgy, chocolately brownies you can bake. I can’t wait to do the rest of the back to basics series 😁
Yeah, I am allergic to dark chocolate so what can I do, Jane?
I find this recipe highly discriminative towards me and my other dark chocolate allergens. I thought I could leave the dark chocolate out but in previous comments, you have said the dark chocolate (the thing I can die from) is ‘vitally important’. I really want to eat these brownies though, what do I do?
Use a different recipe…
Is this a joke comment 😂 I can’t tell.. if this recipe is discriminatory towards dark chocolate allergens then you should stay away from most sweet aisles in supermarkets my hun.
Here’s some logic lola….try searching the internet for a recipe more suitable to your needs! God forbid you actually died from your own stupidity 🙄
Love this recipe, brownies never last long once they are baked in my house, but I have a question is it possible to make this brownie mixture with no extra choc chips? I’m curious if it would work as a smooth brownie (only way I can think to describe it) rather then one with choc chips throughout is that possible? Thank you for all your lovely recipes and hard work x
Hi Jane! I love this recipe..I really want to make tomorrow but I only have medium eggs. Would it work using 4? Thanks!
Hello! Yes this will be fine x
I’m making these tomorrow but I’ve just measured my tin and I think it’s a size smaller than the 9inch you use.
Can I use it? Is there any modifications I need to make?
Thank you 😊
P.S made your Millionaires Shortbread last week and they’re already a favourite in this house!!
