Brookies!

A Delicious & Easy recipe for Brookies – Chocolate Chip Cookie Layer, with a Chocolate Chip Brownie Layer on top!
Recipe Updated September 2020
So I love Brownies, and I love Cookies.. so Brookies are just YES! Like oh my. I have made many a brownie recipe for this blog before, I have made several cookie recipes before – but I decided I would re-make and re-post this recipe for you all!
These treats are utterly indulgent and delicious – its a mix up of my two favourite snacks! I adore cookies (possibly too much) but this is just the ultimate. The cookie and brownie mixtures mashed up together is so yummy that I can’t stop eating them – not great for the diet. But heyyyyyy!
The chocolate chips make it fudgey and gooey and ideal for a treat – I tend to always use milk and white chocolate chips in my cookies and brownies, or all 3 types. The good thing is, you can use whatever flavour you want!!
When baking I recommend using dark chocolate that is 70% cocoa content or darker – and I tend to use 100% cocoa powder too. I find it deepens the flavour of the brownie or cookies to such a wonderful degree, so when you add in chocolate chips it gives the perfect sweetness.
You can of course just chop up some chocolate – you don’t have to buy actual chocolate chips. Personally I prefer smaller chunks of chocolate of chips as it means you get more bits per bite, whereas if you used large chunks of chocolate you may get a piece with barely any!! Kinda sad.
It may seem a little faffy to make them, but honestly it is not and it is worth it. The cookie recipe is basically a plain version of my Mini egg Cookie Bars – and it works a treat. The cornflour is in the recipe to create a DELICIOUS texture, but it is optional. You can use 25g more flour instead.
My Brownie layer in this is also a smaller version of my Triple Chocolate Brownies – as it is literally halved. I find using medium eggs is easier for this, as you often use 4 medium eggs in brownies, or 3 large, so using two medium makes more sense.
But seriously, these are delicious, and will help settle the battle of which to eat, cookies or brownies? Nah, just have Brookies. Always have both if you can have both.
This recipe was updated to just be a bit better – there aren’t major changes – but enough to warrant the change. It is now the same recipe as my Slutty Brownies, just without the oreos! All they are is the same with oreos added in anyway – so it made sense for the recipes to match.
I have however put the original ingredients list below if you wanted to make it – It followed the same method, it was just a slightly different recipe – so feel free to bake it if you liked it.
The original recipe before the update
The original cookie layer was – 115g Unsalted Butter, 50g Granulated Sugar, 75g Light Brown Sugar, 1 Large Egg, 1/2 tsp Vanilla Bean Extract, 125g Plain Flour, 1/2 tsp Bicarbonate of Soda, 1/2 tsp Baking Powder, 1/2 tsp Salt, 75g White Chocolate Chips, 75g Milk Chocolate Chunks
The original brownie layer was – 95g Dark Chocolate, 95g Unsalted Butter, 2 Large Eggs, 140g Caster Sugar, 50g Plain Flour, 20g Cocoa Powder, 50g White Chocolate Chips, 50g Milk Chocolate Chunks
I hope you love these delicious Brookies – any questions, leave them in the comments below! x
Ingredients
Cookie Layer
- 115 g Unsalted Butter
- 125 g Light Brown Sugar
- 1 Medium Egg
- 1/2 tsp Vanilla Extract
- 225 g Plain Flour
- 1/2 tsp Bicarbonate of Soda
- 1/2 tsp Salt
- 1 tbsp Cornflour
- 150 g Milk Chocolate Chips
Brownie Layer
- 100 g Dark Chocolate
- 100 g Unsalted Butter
- 2 Medium Eggs
- 140 g Caster Sugar
- 50 g Plain Flour
- 25 g Cocoa Powder
- 150 g Milk Chocolate Chips
Instructions
For the Cookie Layer
- Beat together the butter and sugar until light and fluffy!
- Add in the egg, and vanilla, and beat again till smooth.
- Adding the flour, bicarbonate, salt and cornflour and beat until a cookie dough is formed!
- Add in the chocolate chips, mix, and press into the bottom of a 9x9" Square Baking Tin, lined with parchment paper.
- Freeze for 20 minutes!
For the Brownie Layer
- Preheat the oven to 180c/160C Fan.
- Melt together your dark chocolate with your butter until smooth.
- Whisk together the eggs and sugar into a thick mousse like mixture, and then fold through the melted chocolate mix.
- Add in the flour, and cocoa powder, and fold through again.
- Mix through the chocolate chips carefully and pour the batter onto the frozen cookie dough.
- Bake the Brookies in the oven for 25-30 minutes, or until baked through. Sometimes it can take a smidge longer! There should be a slight wobble to the mix.
- Leave to cool in your tin for 10 minutes, and then carefully remove and finish cooling on a wire rack. If you want, you can then chill the bake in the fridge for 3 hours or so to help create the fudgey texture.
- Cut up into your portions and enjoy!
Notes
- I think it's important to freeze the cookie dough, to help the brookies bake better. It is optional however! If you want, you can put the Cookie layer into the fridge for an hour instead of the freezer for 20 minutes!
- The Cookie Layer is inspired by my Cookie bars, and the Brownie Layer is inspired by my Brownies!
- These will last for 4-5 days easily, if not longer if they aren't already eaten!
- You can use whatever flavour chocolate chip you want!
ENJOY!

Hi Jane. I am wanting to make this but in a cookie pie. Would I follow the cookie pie method of freezing the cookie crust and brownie filling? And would I alter the cooking time?
Hi Jane! I just made these and they look great! The brownie cooked perfectly but I noticed the cookie was a little soft in the middle, only slightly though. Are they meant to be like this or do you think it needed a little longer in the oven? X
Hiya! This probably just means they needed a smidge longer baking x
Hi how would I do this but with the brownie at the bottom and the cookie layer at the top please? I want to make it for a birthday gift but think it would look prettier with cookie ontop.
Hiya! Its best to follow the recipe as it is, then just turn it over once baked! Hope this helps! x
If I wanted to make these as mini egg brownies would you just recommend hanging the mini egg brownie recipe and adding to the cookie recipe here?
Yes that should be fine! Enjoy! x
Hi, I made these once before and they were delicious. I want to make these as a cheesecake base with your milkybar cheesecake mix on top. Would this work? If so, would I split the mixture into two tins so it’s not so thick? And how long should I then bake it in the oven for? Thank you <3
Hi Jane, the bottom of my cookie dough doesn’t look cooked, but when I slice the brookie the cookie dough looks fine and they taste fine. Is that ok that the bottom doesn’t look cooked?
Hi Jane
Could you make the cookie base into a chocolate cookie and how much cocoa would you need
Thanks
Hiya! Take out 60g flour and replace with 40g cocoa powder. Hope this helps! x
Hey! I tried doing this in a cake tin. Froze the cookie dough before adding the brownie batter as instructed and baked at 160c. However the cookie dough was cooked (a little overdone) but the brownie barely baked at all! I left in for longer than instructed but it was still really raw! Any ideas why this might have happened? Thanks! X
Hiya! When baking brownie – bake until there is a slight wobble in the middle, then leave in the fridge overnight to ‘set’. Hope this helps! x
Hiya, when I have made the cookie dough, can I leave it in the freezer longer than 20 mins? Thanks
Hiya! Yes, cookie dough will last up to 48 hours in the fridge or can be frozen for up to 3 months. Hope this helps! x
Great recipe and these are a hit with my family – thanks Jane!
The only issue I have is getting them baked evenly. I use a 9in square tin. Used dark chocolate for the brownie as stated in the recipe. I baked them yesterday for 30 minutes on 160 fan. The edges and corners were baked (even a little over baked but still nice) but the middle was still a cookie dough/ fudgy brownie batter texture. Any tips on getting them evenly baked?
Hiya! This is right – bake them until there is a slight wobble in the middle, then leave them to ‘set’ in the fridge over night and enjoy! Hope this helps! x
could you use a brownie mix on top instead of making your own?
Hi, I was wondering if the cookie dough base can go in the fridge instead of the freezer as the tin won’t fit in my freezer? If so how long would you keep in the fridge for beforehand? X
Hiya! Unfortunately, by being in the fridge, it will not achieve the temperature it needs to – however I would give it a go for a few hours, but I cannot guarantee the same results! Hope this helps! x
if i wanted to add a layer of nutella inbetween the cookie and brownie layers, would i add that during the freezing stage?
Hiya! You don’t have to, but it may just be easier! x
Hi, just wondering if these can be frozen?
Hiya! Yes absolutely – these can freeze for up to 3 months! x
I don’t have any cornflower 🙁 can I leave it out
Hiya! This would be fine, just replace it with 25g flour! Hope this helps! x
I have made this before and loved it but this time I put it in the fridge overnight because the recipe said to put it in the fridge for 3 hours or so to make it go fudgey. However when I went to go cut it this morning it’s solid. I’ve managed to cut it up, what can I do to make it softer now.
Hiya! If you leave them at room temp for a while they should be fine! Enjoy! x
Tastes amazing! Thank you!!
So happy to hear that! Thank you & enjoy! x
Great recipe, perfect for my daughter bake sale at school. Only issue I found was the brownie took much longer to cook than the recipe stated which then made the cookie layer slightly overdone. Not sure what I did wrong 🤷🏻♀️
Hi Jane… bought your book the other day and working my way through (rather quickly ha). Got so many brownies and blondies in the freezer so I don’t eat them all!
Do you happen to have the nutritional value for the brookite? My son is sending some to his friend who has type 1 diabetes and needs to know carbs etc…
Thank you x
Hi Jane just wondering with your brownie recipes when you say add salt, what type of salt just normal salt or rock salt sea salt???
I always use sea salt in baking!
Can these be done with blondie on top rather than brownie?
Yes, I don’t see why not!x

Hi, do you put in the fridge when they are still warm or once they have cooled completely?
Thanks
Laura
Once they are cool 🙂 x
Hi, your recipes are amazing! We’ve made lots of your cookies and they’re a big hit in our house! With the brookie, do you put it in the grieves once it’s cooled completely or once you e transferred it to the wire rack when it’s still warm? x
Amazing recipe! I’ve just followed this using a 9” square, but the cookie dough hardly covered the tin? Have I missed something?
It’s meant to be a thin layer because of the brownie on top – you just need to spread it more evenly.
Hey Jane, I’ve made so many of your recipes and they’re always amazing! Thank you!
I wanted to know if I doubled the recipe what size tin would I use ?
Hiya, I would suggest using two tins rather than doubling it so they bake correctly. And this applies for your biscoff question too x
Hi, I hope to make these for the 1st time, one question tho : do we leave to cool only 10 mins? And then transfer to wire rack ? Will they not fall apart as usually need to leave brownies in tin to cool completely otherwise they’ll fall
Apart when moving them.
Hiya. No I would cool them in the tin xx
Hi jane! I was wondering if you dont have plain flour at home for the cookies what else could you use? Thanks
Hi Jane would self raising flour work for the cookies or does it have to be plain flour? Thanks!
It really needs to be plain otherwise it will have a cake texture x
Hi Jane! Your recipe’s are amazing! Just wondered if you can substitute the unsalted butter in the cookie part for stork as in your cookie recipes it says to use either? Thank-you!
Hey! Ahh thank you so much! Yes you can xx
Would this work if you made the cookie layer a red velvet cookie using your red velvet cookie recipe? Then chocolate brownie on top?
Hey! Yes it would!xx
Hello jane, just wondering if i was to make these brookies in small cake tins like if they were a brookie pie, what would recommendation be for how long to bake and temperature? Thank you
Hey! Unfortunately I have only tested the recipe for the tin in the recipe so I can’t help you with this I am afraid xx
Hiya!!!
Could you switch the layers up.. have the brownie on bottom and cookie dough on top?
Not really, because of the weight of the cookie dough x
Yes, prepare it as the recipe states then turn it upside down when serving lol
Made these last week for my colleagues on a hospital ward. We all deserved a treat and this was just what we needed. They are amazing and literally lasted seconds! I’ll be naming them again this week xx thanks.
Hi, I made this last night, followed your recipe exactly (I think) and used a 9 x9 inch tin and baked for 30mins but brownie only just done but cookie layer was dry and cakey. Any suggestions as to what went wrong?
Hello! It might be the heat distribution in your oven, but it may be worth lowering the temp and baking for longer instead!x
Can this be made into a “cookie pizza” Or have you another recipe you’d recommend for that. Thanks
My go to brookie recipe! If I were to make these red velvet how much less cocoa / more flour would I use? Thank you:)
I assume you mean the brownie bit? I don’t use the same base as you will never get a ‘red’ colour from it (have a look at my red velvet brownie mix) x
I did your cookie base with my brownie top (halved my usual recipe) and my cookie comes our overcooked everytime….. I do your cookie bars and they cooked in 17mins…. and yes I froze the cookie base for this…any idea why it over cooks so much… its in oven for about 30-8 5mins…brownie comes our perfect
What tray do you bake them in? It may be that they getting too hot and baking for too long!
Would it be possible to make this using your vegan brownie and cookie recipe? Any suggestions would be appreciated as your NYC recipe is absolutely delicious
I was thinking of making a rolo version. Would I used the rolo cookie bar recipe and the brownie recipe from this or would you recommend something different. Thank you!
Yes its probably easiest to make the cookie bars rolo themed, and the brownie from this! x
Delicious – recipe worked great! I did find brownie slightly overpowering on cookie however, only reason not to score 5 star, but that maybe just personal taste! Would like to try again with a blondie on top instead…
Hey!
I made these yesterday, the brownie cooked perfect but the cookie didn’t seem to fully cook so when everything cooked and cooled when i went to slice. it was falling apart as the cookie wasn’t firm at all.
What could i have done wrong?
Still tasted great and love your recipes xx
Did you freeze it correctly before? x
Hey Jane! Want to say I’m a huge fan of yours and your recipes have never failed me.
However this one for some reason didn’t go as planned, the brownie tasted great but needed an extra 25 minutes before it was cooked ! That meant the cookie went slightly hard and was over powdered by the brownie. My oven was on the correct temp so not sure what happened.
Maybe I didn’t whisk the egg and sugar enough?
Thankyou will try again! Xx
What chocolate did you use for the base brownie mix?
Once baked and set for 3 hours in the fridge , should they then be stored in the fridge afterwards or not xx
No, room temp is best!
I made these last night but changed the tin to an 8” as the cookie dough barely covered the recommended 9” tin…. fantastic results with defined layers just like the image shown
Hi can you use a tray bake tin?
It depends on the size, as tins volume vary a lot!
Amazing! I wish I’d used white chocolate chips for the brownies, as yours look prettier! But there’s always next time
Hey jane love this recipe! Although my cookie layer doesn’t go as thick as urs does in the image is there a certain way to achieve this? I used the same size tin as u?
I just do exactly what is written in the recipe – but also I wouldn’t say a photo is the best comparison as it’ll never be the exact same every time! As long as it bakes okay it doesn’t matter.
Hi Jane
My cookie dough is sticky when done what am I doing wrong 🤦🏻♀️
Do you mean after its baked? It might just need a bit longer in the oven?
Sorry Jane, no when I’m making so before baking x
Ah right, well it can be sometimes but it shouldn’t be super sticky. It could be the butter was too soft, or the egg too large so too much moisture. As long as you freeze it though still it should be fine x
Hi! This looks amazing! How can I make the cookie base into a black cocoa base? Kind
Of like the colour of triple chocolate cookies. And just out of interest what’s the difference if you make brownies with milk chocolate or dark chocolate? Thank you x
You can substitute 25-30g of flour for cocoa powder for the cookie, and you should never use milk chocolate for the base of the brownie mix. x
I used baking paper to dress my cookie dough into
the tin, doesn’t stick and flattens the dough into the tin really well 🙂
Hi Jane, how long would you recommend baking in a 9×13 tin? I was planning on making 1.5 times the recipe? Ps you are incredibly talented, your recipes are all delicious
I’m really unsure I am afraid as I have never baked in that size before – but 1.5x is correct!
OMG, I’ve made these 3 times so far & my work colleagues are loving them !!. Almost as much as my husband and kids do – in fact my Type 1 diabetic, 12 year old son says that it is worth having to take extra insulin because they taste soooooooo good. Love the fact they are so easy to make & have made them with chopped supermarket bar chocolate as well as the choc callet brand you recommend and they tasted equally delicious. Will certainly be making more to give as homemade Christmas gifts
If you wanted to do a Mars Bar version would you freeze the Mars bar?? And would you add the layer of Mars bar chopped or whole? Thank you!
I would definitely freeze the mars bar because of the filling – I would personally chop the mars bar x
Love this recipe so much, gets better each time! How would I go about making blonde brookies? Is it possible? Please don’t stop posting these delicious recipes Xx
The theory is that you can use half of one of my blondie recipes (like this is half of the brownie) and try that!
Made these today for a treat for the kids lunchboxes… The husband can’t leave them alone 😂 I did have to leave them in the oven for longer but they are just the right amount of gooeyness! I shall certainly be making them again and trying more of your recipes!
Hi Jane,
can you use stork butter for these or does it have to be unsalted?
Yes you can!
Perfect, thank you lovely! Xx
Hi Jane,
Recipe looks incredible and I’m going to try tomorrow.
If I substitute the plain flour for gluten free flour will I need to adjust anything else?
Thank you 🙂
No it should be fine as long as everything else you use is GF safe!
Hey Jane,
Planning to make these but I only have an 8 by 8” tin. Should i reduce the ingredients by an 1/8th or should i just go along with the original amount of ingredients?
Thanks x
Volume wise the tin is actually about 1/5 smaller – so it would be best to reduce it if you can, or bake for longer and accept they may be a bit gooey in the middle haha!! x
Oh my goodness these are heaven!!! Literally so easy to make and so yummy!!
Great recipe idea. I Baked in an 8 inch pan for 40 minutes but the brownie was still a little raw in the middle. Is that normal? I think next time I’ll try not freezing the cookie dough. My oven, as far as other recipes go, appears to be perfect so I cant figure out what else might help it cook evenly
It’s because you used a smaller tin than listed – the volume difference can cause a big problem. If you used the correct tin size it would be much better x
Just made these today, I’m not an avid baker but I had to make these lol.
I had an issue with my cookie dough not rising much, the brownie was perfect (according to my wife that is haha)
The cookie dough was quite flat, any idea what could be going wrong, I thought it could have been the tray I used… might be too big? I didn’t go out and buy a tray especially for this as wanted to keep costs low over this lockdown period lol, I had all the ingriedients in my pantry ☺️
The cookie dough isn’t meant to rise much at all – so it’s probably just worked correctly, but if the tin was a different size, that could definitely change things!
Just made these, and YUM, was just wondering if they Would freeze well once cooked? We love the lemon bars because we freeze them and have a constant stream of fresh bakes!
Yesss they can be!! So glad you like them!
I made these on Saturday and they were absolutely delicious! They might even be a new personal favourite! Just wondering, could you make these with a blondie layer on top instead and what measurementS would you recommend? Thank you x
Could I leave the cookie mix in the freezer over night and finish off tomorrow? Or would it be too frozen?
That would be fine! x
I made these this evening, but my brownie layer just did not want to cook 😩 it ended up being in the oven for a long time which turned my cookie layer into more of a cakey layer. I mean they taste good but what am I doing wrong?
Did you definitely use dark chocolate for the brownie mix – and then did you make sure you were careful when mixing it? Those two are very very key to it! x
Can these be made in a 7” tin? If so, do I halve the recipe? Does the baking time change?
Yes – if you halve it it will take less time xx
Just made these… they taste soooo good. The cookie recipe seemed to rise to and mix with the brownies. Don’t really mind too much cause the taste is AMAZING but have you any idea why this would happen?
This can just happen sometimes – but it’s not a problem! xx
I followed the recipe, but the cookie recipe rose to the top and didn’t cook after 40 mins (the brownie bit did). Didn’t stop us eating it as a pudding though 🙂
Oh no! I’m glad they were yummy though – I will be updating this recipe soon, but my Slutty Brownies post is brookies with oreos in and is different so may be better for you!
This is my second recipe of yours that I’ve tried and I’m so impressed how reliable they are. What always amuses me is that you give a shelf life on your recipes but they’re never around more than a day in our house! These turned out perfectly, and although I’m a bit of a brownie purist (if it ain’t broke) I will admit to enjoying these more than I wanted to. Thanks for sharing…now to choose what to bake next!
Hahah I always have to put shelf lives juuuust in case – but they never last long for me either! So glad you liked them!
Made these yesterday and they were delish!! Layers weren’t as defined but they still tasted amazing.
Ohh I am so glad, Christine! Thank you for making them!!
I made these today using Terrys chocolate Orange, Jane that’s your fault. They don’t have defined layers of cookies and brownies but if they taste great then hey ! so what. I haven’t tried them yet. I’ll try and upload a photo later
Sorry didn’t mean to upload twice doh !
Made these today, haven’t tasted them yet but they look delicious. Made mine with Terrys Choc Orange , Jane that’s your fault,. They took quite a while longer to cook, and I haven’t got a defined layer of cookie and brownie but hey if they taste ok I don’t mind. I’ll try and upload a photo later.
Haha Terry’s is best!!
They’ve all gone my husband took them to work and they didn’t last long at all !
Ahh amazing!!
OMG… That’s all that comes to mind. I´m dying because I don’t have one right now. Amazing!
Hahaha I wish I could send you some! Thank you!
