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!

    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

    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!

    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?

    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?

    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!
