 I have taken two of my most popular recipes and sandwiched them together to form these divine Brookies

Published April 30, 2024, Updated April 4, 2024

These Brookies are a combination of my One Pot Brownie and my Chewy Chocolate Chip Cookie recipes, two of the most popular recipes on my website!

This is 100% not an original idea, I was in a café a few months ago and saw these in the cabinet and thought I could totally come up with my version of that! So I got creating, and these delicious morsels are the end result.

If you are looking for a healthy recipe you might wish to skip this one! It has all the deliciousness of a brownie and a cookie combined. Rich, decadent and sweet.

I played around with the quantities of both recipes to reduce them and get the right balance of brownie to cookie. These are just a fun decadent treat that will impress your sweet loving friends.

The ingredients are simple pantry basics, as follows

  • Butter

  • Plain White Flour

  • White Sugar

  • Brown Sugar

  • Baking Soda

  • Eggs

  • Cocoa

  • Salt

  • Vanilla

  • Chocolate Drops or Chips

Ideally you will want to use a stand mixer for this one as it makes the first step of mixing the butter and sugars easier  or an electric hand held beater. I first make the brownie then wash the mixer bowl and then make the cookie layer.

How to make the brownie layer of a brookie

 

I have reduced my brownie recipe by a third, it is so easy to make. Simply a matter of combining the butter, sugar, vanilla and salt and mixing well until pale and creamy. Then adding the eggs one at a time and combining well. 

 

The trick to a good brownie is not overmixing once you add the flour and cocoa as this makes a fluffy cakey brownie, where we want a rich dense one. So when we finally add the cocoa and flour its just a light combination. 

A prepared brownie pan and brownie mixture in a bowl

 

Preparing the baking pan is important, you want the sides of the baking paper to overlap so that you can lift out the whole slice once cold, so ensure this step is taken.

Carefully spoon the brownie mixture into the prepared pan and spread evenly then set aside while you prepare the cookie layer. 

Then I clean out the mixer bowl, dry and start on the cookie dough using the same bowl.

 Again a lovely simple recipe, combining the butter and sugars, then adding the eggs until the mixer is lovely and light and creamy. Then I pour in the dry ingredients and lightly fold through before mixing through the chocolate.

You do need to take care adding the cookie layer to the brownie. Normally with this cookie dough you would chill it before baking but no need here for a slice. 

How to layer and spread spoonfuls of cookie dough over the brownie mixture

 

I take spoonful’s and place gently on top of the brownie and gently spread it out as I place it on the brownie. You want the cookie layer to completely cover the brownie if possible. 

 

Then I will bake the slice for 20 minutes covered then at least a further 20 uncovered until the cookie layer is golden brown and the brownie layer is no longer a wet batter. 

 

It is important for this recipe that the Brookie slice completely cools before removing it from the pan and slicing it. You can serve it warm or cold, and of course it will freeze beautifully for another day if needed. 

 

I hope you love my version of Brookies, the perfect combo of Brownie and Chocolate Chip Cookies in a slice.

So onto the recipe for my version of Brookies.

Brookies (Brownie & Chocolate Chip Cookie Slice)

Brookies (Brownie & Chocolate Chip Cookie Slice)

Yield: 20-24
Prep Time: 30 minutes
Cook Time: 40 minutes
Total Time: 1 hour 10 minutes

Delicious, decadent and so easy, a lovely combinati0n of Brownie and Chocolate Chip Cookies

Ingredients

BROWNIE LAYER

  • 115 grams Butter, melted
  • 1 Cup White Sugar (205 grams)
  • 1 teaspoon Vanilla Essence
  • 1/4 teaspoon Salt
  • 2 Eggs, medium
  • 2/3 Cup Cocoa Powder (55 grams)
  • 1/4 Cup Plain White Flour (37 grams)

COOKIE LAYER

  • 1 Cup Plain White Flour (150 grams)
  • 1/4 teaspoon Baking Soda
  • 1/4 teaspoon Salt
  • 85 grams Butter, melted
  • 1/2 Cup Brown Sugar (100 grams)
  • 1/4 Cup White Sugar (50 grams)
  • 1 1/2 teaspoons Vanilla Essence
  • 1 Egg, medium
  • 1 Cup Chocolate Drops or Chips (175 grams)

Instructions

  1. Preheat the oven to 170C Bake
  2. Prepare a 25cm square baking pan with baking paper, spray the pan first with cooking spray then lay a piece of baking paper so that it overhangs on two sides to make for easier removal later.
  3. Make The Brownie Layer
  4. In the bowl of a stand mixer add the butter, sugar, vanilla and salt and mix for 4 minutes until it changes colour
  5. Add to this the eggs one at at time and combine for a minute or two per egg until the mixture is pale and creamy
  6. Sift into this the cocoa powder and flour and mix until only just combined, careful not to over mix this stage.
  7. Spoon the brownie mixture into the prepared container and spread evenly, then set aside
  8. Make The Cookie Layer
  9. Clean out your stand mixer bowl and paddle and dry it ready for the cookie layer
  10. In a small bowl combine the flour, baking soda and salt, mix and set aside.
  11. In the stand mixer bowl add the melted butter, brown sugar and white sugar and mix for 4 minutes on medium to cream together the sugars.
  12. Add to this the vanilla and egg and beat well for a further 2 minutes until pale and creamy
  13. Pour into this the flour mixture and mix until just combined.
  14. Finally add the chocolate drops and carefully stir these through.
  15. Take spoonful's of the cookie mixture and gently place on top of the brownie layer, gently spreading each spoonful as you place it. The dough is soft and sticky so does spread well.
  16. You want the cookie dough to cover the entire brownie mixture as evenly as you can without pressing the dough into the brownie.
  17. Cover the Brookie with aluminium foil and bake for 20 minutes
  18. Remove the foil and bake for a further 20-30 minutes until the cookie layer is golden brown and a knife or skewer comes out clean but moist from the brownie layer.
  19. Allow the Brookie to completely cool before removing it from the pan using the baking paper overhang.
  20. You can speed up this process by popping it in the fridge once it has cooled down adequately on the bench
  21. Run a knife around the edge with no baking paper and carefully lift out the brownie and place on a wooden board to slice into small squares for serving.
  22. Store in an airtight container until ready to eat. Will keep well for 4-5 days at room temperature.
  23. You can freeze the baked Brookie, wrap well in plastic wrap either sliced or whole and then store in an airtight container in the freezer.
  24. Enjoy!

Notes

What measuring cup size do you use?

My cups are 250ml

Can I mix the cookie dough through the brownie mixture in dollops rather than a layer?

Absolutely, I just prefer the even look and taste of the layers which is why there is a thick layer of cookie.

Can I freeze Brookies once they are baked?

Yes! Once the Brookies are completely cold you can remove from the pan and wrap well in plastic wrap then into an airtight container to freeze. Remove the night before you wish to eat it and leave it at room temperature.

      This is my job now, one I started when my youngest was 4 so I had a bit of time when she was in day care and in the evenings. You are right in what I think is the hardest time of parenting, they are so dependent on you and your eyes at all times! I would give yourself some grace, if they are happy to sit in the bouncer or by you while you bake for pleasure then go for it! Otherwise use your time as you need and buy a packet of biscuits or a slice from the supermarket. They are only little for such a short time.
