A delicious and easy recipe for Brookies with a chocolate chip cookie dough layer and chocolate brownie on top
What are brookies
Brookies can come in varying forms, but it’s essentially always the combination of brownie and cookie together. These are brookie bars, so a traybake version – and they are so easy to make.
So I love brownies, and I love cookies.. so brookies are just YES! I have made many a brownie recipe for this blog before, I have made several cookie bar 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 part
The cookie part of this bake, is basically the same as my other cookie bars. It’s a recipe that works, and it combines really well with the brownie part as well.
- Butter – you can use an unsalted butter or a baking spread for ease
- Sugar – I like to use light brown soft sugar but you can use any really. Granulated sugar, or a combination is nice
- Egg – A medium egg or a large egg works perfectly.
- Vanilla – Optional, but delicious as always
- Flours – I like to use plain flour and then add in a little cornflour as mentioned below
- Raising agent – Bicarb is basically essential in all cookie recipes for the texture that you are also after
- Salt – I love adding salt to my bakes, but I understand that not everyone does so I totally understand if you don’t want to
- Chocolate – you can basically use any chocolate you want, but I like to use milk chocolate typically
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.
The brownie part
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.
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.
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 – for these I just used white because I wanted the contrast with the dark brown colour of the brownie.
Baking the brookies
I personally recommend starting with the cookie bars as you want to prep the cookie dough, and then freeze for at least twenty minute before baking. You have to freeze the cookie part of the recipe first because typically brownies and cookies have different baking times.
While the cookie is freezing you can preheat the oven, and then prep the brownie mixture. Because it’s typically less brownie mixture than normal, it doesn’t take long to make at all.
Once you have poured the brownie on, you bake in the preheated oven until there is a small wobble in the middle. A knife test doesn’t work for brownies as they contain so much chocolate so the wobble test is best.
Once they have baked, leave to cool at room temperature and then set them in the fridge for a really fudgy texture. This part is optional, but I love setting them in the fridge personally!
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.
Original recipe
This recipe was originally published in April 2016, so over the time I have adapted and changed it to suit my increasing baking knowledge and preferences, but I will always include the original recipe when I do this incase you love the old version.
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
Tips & Tricks
- 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, in the fridge or at room temperature
- You can freeze these for 3+ months once baked
- You can use whatever flavour chocolate chip you want

- 100 g dark chocolate
- 100 g unsalted butter
- 2 medium eggs
- 140 g caster sugar

Instructions
For the Cookie Layer
- Beat together the butter and sugar until light and fluffy
- Add in the egg, and vanilla, and beat again until 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 180ºc/160ºc fan.
- Melt together the dark chocolate with the 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.

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?
