Satisfy all of your cravings with a batch of these soft and chewy brown butter brookies. Made with equal parts brown butter chocolate chip cookie and rich, dark, ultra fudgy brownie, these one pan wonders are the ultimate chocolate lover’s treat. Get the best of both worlds with this crowd pleasing dessert!

So here’s the thing.

You know how I always say that classic chocolate chip cookies are my all time favorite dessert? Well…I take it back. One bite of these dangerously delicious brown butter brookies and I’m like “chocolate chip cookie who??”. If you aren’t yet familiar with brookies, allow me to introduce you to the most chocolatey, chewy, fudgy, crazy delicious cookie bar ever!! It’s a real double doozy of a dessert and you’re going to LOVE them.


Brookies are the ultimate dessert lover’s treat for those times when you can’t decide between a cookie and a brownie. Pretty much sums me up in a nutshell. What can I say? My sweet tooth wants it aaallllll!! With a brookie, you get a cookie and a brownie all rolled into one rich and decadent dessert. You simply can’t go wrong. The concept is brilliant really and the person that invented the all mighty brookie deserves a gold star. These brown butter brookies are made with equal parts of my go-to chocolate chip cookie with a twist {hello brown buttah!} paired with a deep, dark, ultra fudgy brownie.

Brookies can be made in cookie form as seen here with my brookie ice cream sandwiches. But they are even better made into bars if you ask me. I don’t even care that this recipe feeds a crowd because I want them all to myself.


A few notes worth mentioning before we dive right into the recipe for these seriously delicious brown butter brookies. First, don’t skip the brown butter. Just don’t. The flavor of the brown butter in the cookie dough really can’t be beat and it’s worth going the extra mile. And since I know you’re going to ask, the answer is yes. You do have to chill the brown butter before creaming it together with the sugars. Don’t mess with a good thing I always say and this recipe is a very good thing. These brookies are hella good straight from the oven but for those clean, sharp edges be sure to cool the bars completely and consider chilling the pan in the fridge for a bit before slicing with a sharp knife.


The beauty of this recipe is that it comes together in about an hour with standard ingredients that you likely already have in your pantry. There are a few steps involved as we are working with both cookie dough and brownie batter but neither is complicated on its own. Check this list for ingredients you need for the best ever brown butter brookies and get baking!

Flour. Just regular all-purpose will do. Nothing fancy here.

Butter. You’ll use both brown butter for the cookie dough and regular melted butter for the brownie batter in this recipe. No need to set butter out in advance to soften so you can get to baking the minute the craving strikes. If you haven’t browned butter before, don’t you fret. Check out this post for the how-to and everything you need to know to brown butter like a pro.

Sugar. Grab the granulated sugar and the brown sugar from your pantry bakers. The combination of white and brown sugar adds both sweetness and moisture to these brookies. Dark brown sugar will work just as well if that’s what you have on hand.

Eggs. Don’t forget to set your eggs out in advance to reach room temperature before beginning to mix your dough and batter.

Baking soda and baking powder. We need both types of leaveners in this recipe to help give the brookies texture and rise. Check your expiration dates to be sure they are fresh.

Chocolate. That high quality cocoa powder and high end chocolate chips are totally worthy of these brookies. Use the good stuff here friends.


Brown that butter. At risk of sounding like a broken record, don’t skip this step. Brown butter is pretty much liquid gold. It gives the most delicious, slightly caramelized flavor that pairs perfectly with the bittersweet, fudgy brownies. If you are new to browning butter, follow this step by step guide for everything you need to know.

Use good chocolate. I’ve made this recipe both with chopped dark chocolate and with bittersweet baking chips. Both are winners in my book but I’ll let you decide which is best. Either way, I highly recommend using a chocolate with at least 60% cacao.

Do not over mix. Less is more when it comes to mixing. Use a light hand when mixing both the cookie dough and the brownie batter and use a spatula to fold in the chocolate chips so that you do not risk over working the cookie dough.

Watch your oven. Every oven runs differently so keep an eye on your oven to prevent over baking. To keep the top from browning too quickly, place a large piece of aluminum foil loosely over the top around the 25 minute mark. The brookies are done baking when the edges are golden brown and the center is almost set. The bars will continue to bake when removed from the oven.

Cool completely. Waiting for this pan of soft, chewy, rich chocolatey brookies to cool is not exactly my idea of a good time, but I promise you it is well worth the wait. These bad boys will slice up perfectly when cooled completely and slightly chilled for a clean cut.


You’ll be happy to know that these one pan wonders are super freezer friendly, although I’m guessing they won’t actually make it that far. Truth be told, I love noshing on them straight from the freezer on a hot day. Or top with a giant scoop of vanilla ice cream and a drizzle of hot fudge for a positively decadent treat. If you do decide to store your brookies in the freezer, wrap the squares in a layer of plastic wrap followed by a layer of aluminum foil for safe keeping. Defrost the bars at room temperature.

There’s a lot to love about these half cookie, half brownie treats. They really are the perfect dessert and I have a feeling these brown butter brookies are going to be your new favorite. If you make ’em, I want to hear all about it. Enjoy every morsel my friends!

Happy baking!

For Brownie Layer

  • 5 ounces bittersweet chocolate (I use 60% cocao)
  • 1/4 cup (57 g) unsalted butter
  • 1 large egg plus one egg yolk, room temperature
  • 1/3 cup (67 g) granulated sugar
  • 1/4 cup (50 g) light brown sugar, packed
  • 1 tsp vanilla
  • 1/4 tsp baking powder
  • 1/3 cup (42 g) all purpose flour, spooned and leveled
  • 3 tablespoons (23 g) Dutch process cocoa, sifted
  • 1/4 tsp kosher salt

For Chocolate Chip Cookie Layer

  • 1/2 cup (113 g) unsalted butter, browned, strained, and chilled for one hour
  • 1/4 cup (50 g) granulated sugar
  • 1/3 cup (57 g) light brown sugar, packed
  • 1 large egg, room temperature
  • 3/4 tsp vanilla
  • 1 cup plus 2 tablespoons (143 g) cups all purpose flour
  • 1/2 tsp baking soda
  • 1/4 tsp kosher salt
  • 3/4 cup (120 g) chocolate chips (I use a mix of bittersweet and semi-sweet chips)


  1. **Note: brown the butter for the chocolate chip cookie layer first and refrigerate it for 45-60 minutes before you begin mixing the brownie layer.

For Brownie Layer

  1. Preheat oven to 350 degrees.
  2. Spray a 8 x 8 inch pan with non-stick baking spray and line the bottom and sides with parchment paper. Allow the edges of the parchment to extend over the sides of the pan for easy removal of the bars once cooled.
  3. In a medium saucepan over low heat, melt the chocolate and butter together. Stir often until the butter is melted and the chocolate is smooth and shiny. Remove the pan from the heat and set aside to cool slightly.
  4. In the bowl of a stand mixer fitted with the whisk attachment, beat together the egg, egg yolk, sugars and vanilla on high speed for 4-5 minutes until the mixture is thick and pale in color.
  5. Reduce the speed to low and add in the cooled, melted chocolate and butter mixture. Mix until incorporated.
  6. In a separate bowl, whisk together the flour, cocoa, baking powder and salt.
  7. Remove the bowl from the mixer and use a spatula or wooden spoon to fold in the dry ingredients until just barely combined. Do not over mix.
  8. Set aside until ready to assemble.

For Chocolate Chip Cookie Dough

  1. To brown the butter, place butter in a medium saucepan over medium heat. Stir occasionally until butter has melted. Continue stirring often as butter begins to foam and crackle. Do not leave the butter unattended at this stage. Stir the butter as it sizzles and after about 4-5 minutes, bits of golden brown butter will fall to the bottom of the pan. The crackling sound will stop and the butter will be aromatic and amber in color.
  2. Remove the butter from the heat and pour it into a heat safe bowl through a fine mesh strainer. Discard the brown bits of butter that remain in the strainer.
  3. Place the bowl of brown butter in the refrigerator for 45-60 minutes or until cooled and firm to the touch. You can speed this up after about 30 minutes by placing the bowl in the freezer.
  4. Once cooled, spoon the brown butter into the bowl of a stand mixer fitted with the paddle attachment.
  5. Add the sugars and beat on medium high speed for 2-3 minutes until light and fluffy.
  6. Add the egg and vanilla and mix until well combined.
  7. In a separate bowl, whisk together the flour, baking soda, and salt.
  8. With the mixer on low speed, gradually add the flour mixture in 3 additions. Scrape down the sides of the bowl as needed. Do not over mix. A few streaks of flour remaining is ideal.
  9. Remove the bowl from the stand mixer and use a spatula to fold in the chocolate chips.

To assemble the brookies, start by spooning about 1/3 of the brownie mixture into the bottom of the prepared pan using an offset spatula to roughly smooth it evenly across the bottom of the pan.

Alternate spoonfuls of chocolate chip cookie dough and brownie batter across the pan, creating a mottled look.

Continue until all of the cookie dough and brownie batter are used.

Gently press the mixtures down with an offset spatula, leveling the top just slighty. Do not over work the dough or flattened the mixture too much.

Bake at 350 degrees for about 25 minutes or until the edges are golden brown and the center of the brookies is set. If the cookie dough begins to brown too quickly, place a piece of aluminum foil loosely across the top.

For firmer brookies, bake for closer to 40 minutes. For gooey brookies, bake for less time.

Remove the pan from the oven and cool completely before slicing.

For sharp edges and even slices, chill the brookies for one hour before slicing with a sharp knife.


Brookies freeze well. Wrap tightly in a layer of plastic wrap followed by a layer of aluminum foil. Defrost at room temperature.

    Hi! I was wondering if I could substitute the Dutch processed cocoa powder with natural unsweetened?

    If not, which brand of Dutch processed powder would you recommend? Seems hard to find in my grocery stores!

    Thank you in advance!

    hello! I was wondering if it’s possible to make this layered, like put the brownie layer at the bottom and ccc layer on top? instead of swirled together

    Quick question-
    Recipe states to use an 8×8 pan but one of the questions/comments is asking about making half the recipe and you suggested an 8×8 or 9×9. Should the recipe be made with a 13×9 for the recipe as written and 8×8 for half the recipe?

    Thank you. Can’t wait to try them.

      Hi! Sorry for any confusion. This recipe was originally written in 2020 for a larger 13 x 9 inch pan. Lots of readers were asking for a smaller portion so the recipe has since been revised to make an 8 x 8 pan. Enjoy!

        Hi Heather. What is the original recipe for the 9×13 pan? Thank you.

        This recipe was revised for a smaller, more manageable 8 x 8 square pan size. You can always double the recipe and make it in a 9 x 13 pan.

    Love this brookies! I do reduce half of the white sugar because I was afraid it will be too sweet (we don’t have bittersweet chocolate in my country, they’re all sweet) and it turned out just right. The texture is a so good, brownie and soft cookies with a bit of crunch at the top. The smell of the brown butter is so yummy… Can’t get enough. Thanks for the recipe!

    Was so delicious and made so many! I wish I had baked it a little less to get the best texture but it was still devoured very quickly by me and my friends. I converted everything to grams using online tools and it worked well. I used chopped chocolate instead of chocolate chips and next time I’ll be putting something into the brownie!

    Baked them today. The cookie part was a bit dry (I’m using KA flour and without using weight measures it could have been too much flour). The baking time was correct (and my oven is calibrated) as the brownies were nice and gooey (and tasted great), but the cookie part was drier. I’m sure people at work will love them though.
    Overall, I wish weight measurements were added to the recipe.

      Hi Naomi! Thanks for trying my recipe. These brookies are definitely best when slightly under baked. We are working on adding weight measurements to all recipes so stay tuned!

      Hi! I have not made this recipe with an egg substitute but you could try a flax egg. Keep in mind the texture will be a bit different if you make substitutions.

      How can I make this into heart shape like you have it on the picture prior to clicking for recipe?

      • Heather Mubarak

        To make these heart shaped brookies, layer the cookie layer on top of the brownie layer and then bake. Rather than swirling the two batters together. Once they have cooled, cut into heart shapes using a cookie cutter. Enjoy!

    I swoon over swirls and knew the minute I saw the photo that I had to make these. Seriously delicious! The process is a little involved, since you’re making two separate recipes, but it makes a large batch, so you’ll have treats for days. I baked mine in a 9×13 Pyrex pan for 30 minutes, and they were perfect (my oven thermometer showed the temp was slightly above 350). I didn’t have as much baking chocolate as I thought I did, so I ended up using 8.5 oz of assorted 72% cacao and 1.5 oz of 100%. Yum!

      Hi! I don’t recommend making this recipe in a microwave oven. The brookies should be baked at 350 degrees in a standard oven.

      I haven’t tried this recipe in a smaller pan just yet but if you want bake half of the recipe I would recommend a 8 x 8 or 9 x 9 inch pan. Let me know how it goes!
