Crumbl Brownie Batter Cookies
These Crumbl Brownie Batter Cookies are chocolate, cookie and brownie heaven! The bottom is completely set, the tops are crackly (just like Homemade Fudgy Brownies are!) and best and most important part is that the centers are fudgy!
Crumbl has had a few brownie based cookie recipes they’ve come out with. Since I’m such a BIG fan of brownies AND cookies, I had to make copycat Crumbl cookie recipes of them! Which will you try first? There’s the Crumbl Peanut Butter Brownie Cookies, Crumbl Mint Brownie Cookies, and Crumbl Cosmic Brownie Cookies!
Why This Recipe Works
- Fudgy centers. Is it really a brownie batter cookie if the centers aren’t fudgy? No way! These brownie mix cookies are baked (you can tell because the bottoms are fully set) but the centers remain fudgy — just like actual brownies! If I could only give you one reason this is the best brownie mix cookie recipe, it would be fudgy centers! Lucky for you, I have a few more reasons…
- Includes Dutch process cocoa powder. Adding a bit of Dutch process cocoa powder in the brownie mix cookies brings in a deeper chocolate flavor and a richer color.
- Brownies in cookie form! You can tell this is a cookie recipe and not a brownie recipe because there is added baking soda! That gives a little bit of rise to the cookies, making them more like cookies. Brownies don’t usually have a leavening agent in them.
Ingredient Notes
- Brownie Mix: You can use whatever brownie mix you prefer. I’m a sucker for Ghirardelli brownie mix cookies, so that’s the type of brownie mix I used.
- Unsalted Butter: Using melted butter will make these Crumbl Brownie Batter Cookies more like brownies. Cookies traditionally use softened butter instead of melted butter, making the cookie dough less gooey. Using the melted butter will help these cookies be fudgy and brownie-like.
- Flour: Adding a little bit more flour will give the mixture more of a dough-like texture, instead of liquidy like brownie batter.
- Dutch Process Cocoa Powder: Adding a little bit of Dutch processed cocoa powder will deepen the chocolate flavor.
- Light Corn Syrup: Adding a bit of light corn syrup will keep the cookies nice and moist, further helping our desire for soft and gooey brownie like insides.
- Baking Soda: Brownies don’t typically include baking powder or baking soda. Adding it to the Crumbl Brownie Batter Cookie recipe will help give more of a risen texture typical to cookies.
Step-by-Step Instructions
- Make the brownie mix cookie dough. Add the brownie mix, butter, flour, cocoa powder, eggs, corn syrup and baking soda to a large bowl. Mix to combine. (I used a hand mixer).
- Add the chocolate chips. Stir in the chocolate chips.
- Portion into cookies. Using a 1/4 cup, portion the cookies into balls.
- Bake. Bake the brownie batter cookies at 350°F for 11-12 minutes or until the edges are set and the top are crackly. Remove from the oven. Do not over bake.
- Let cool. Let the cookies cool on the baking sheet for 10 minutes. Then transfer to a wire rack to cool completely. Enjoy!
Recipe Tips
You can add milk chocolate chips rather than semi-sweet chocolate chips if you’d like to offset some of the deeper chocolate flavor.
The dough will be softer than a traditional cookie dough because we are trying to make a fudgy brownie cookie!
Do not over mix the dough. Over mixing can produce a tougher consistency, which will affect the bake.
You won’t want to over bake these cookies! Remove them from the oven when they edges look set and the tops are crackly. Remember, the cookies will continue to bake while they cool on the cookie sheet for 10 minutes.
Some cookies may have uneven edges. To fix this, use a very large round biscuit cutter or cookie cutter and, immediately after removing the cookies from the oven, gently use the cutter in a circular motion around the cookies to tuck in the edges (think hula hoop motion). We don’t want to cut the cookie. We just want to make the cookies uniformly circle before they set. For a video of what this looks like, check out my Instagram page.

This recipe uses Dutch processed cocoa powder. Read more on the Best Cocoa Powder for Baking to know why we use this cocoa powder instead of unsweetened!
Make Ahead, Storing, and Freezing
Store the cookies in an airtight container or Ziplock bag at room temperature for 4-5 days.
To freeze the dough, form into balls and flash freeze until firm on a baking sheet. Transfer to an airtight container or Ziplock bag and freeze for 1-2 months. You may want/need to layer parchment paper between the cookie dough balls so they don’t stick together.
Remove and bake from frozen or let thaw and bake. If baking from frozen, you’ll need to bake for another minute or so. Just remember to remove the cookies when the edges are set and the tops are crackly.
To freeze, let the cookies cool completely. Then wrap each cookie in plastic wrap and store in an airtight container or Ziplock bag in the freezer for 1-2 months. Remove and let thaw.
Recipe FAQs
Yes you can! Follow along with my step-by-step instructions above. You’ll need a little extra flour, a leavening agent and a few other ingredients to turn brownie mix into cookies!
That’s fine! You can use unsweetened cocoa powder if you want. I wouldn’t omit it because the recipe accounts for the added powder from the Dutch processed cocoa powder. However, I will put a plug out there for getting some Dutch processed cocoa powder to use! When it comes to knowing the Best Cocoa Powder for Baking, understanding why different cocoa powders are used can be really helpful!
Due to the nature of these cookies trying to be brownie-like, the dough will be softer than a traditional cookie dough. That’s OK! We want the cookies to be as close to brownies as we can so we get that crackly top and fudgy center. You won’t need to add more flour (and I don’t recommend it) because it can make the cookies drier and not at all fudgy.

I ad some extra flour and refrigerate then. Just love it.
So happy you loved this cookie recipe, Mariel! Thanks for the 5-star rating.
any substitute for corn syrup?
Probably the closest substitute to corn syrup (so you get the same/similar results) is molasses. Downside is molasses has a noticeable flavor and corn syrup doesn’t.
Hi Whitney! What can I do if my brownie mix is 20 oz and not 18.3?
Just take out some of the brownie batter until you reach 18.3 oz.
Help!? I tried this recipe today. I baked my cookies 11 minutes and the center was so gooey the cookie couldn’t even be picked up. I cooked them again for 13 minutes. Same thing. The only thing that I didn’t follow was having an oven thermometer, which I am placing an order on Amazon for. Any other possible solutions?!? They taste yummy minus the overly gooey unbaked center 😂🥴
Hi Vanessa! Are you letting them sit for the appropriate time on the baking sheet before removing them to a cooling rack? The cookies will continue to set up on the bottoms while they cool on the baking sheet. This will help the bottoms set so you can pick them up. But I will say that the centers of the cookies will be slightly gooey because we are recreating gooey brownies in cookie form. BUT the bottoms should set up nicely so they are easy to pick up. The oven thermometer will help! Let me know about if you are cooling them on the pan and then we can troubleshoot from there.
Yes!!!! I actually left them on the pan and walked away and returned an hour later thinking I would have to deal with the undercooked cookies but they were just fine. It needed like an hour or so to set. When I finished the rest of the batch I just let them sit for an hour and I had no issues. Thanks for replying back. I use a lot of your desserts and love your recipes. This was the first one I struggled with.
Happy to help! I’m glad they worked out. And thanks so much for making my recipes! And for coming back and sharing your experiences. It helps me and it helps my readers.
I absolutely love this recipe I’ve probably made at least 8 batches and have another 4 to make today my only complaint is there isn’t enough! If you love brownies this is your cookie it’s the best of the edge of the brownie but also soft like the middle if you haven’t tried them your seriously missing out
Hi! Can’t wait to make these! Can the dough be made the night before baking and set in the fridge? If so, does the dough need to sit out until room temp before baking?
Yes you can make the dough the night before. I would let it set out for 20 minutes or so, but no it doesn’t have to be to room temperature before baking.
Mine also turned out flat, even when I had already added at least an extra tablespoon of flour. I melted the butter, which think was a mistake for these. I will try again, add 3 extra tablespoons of flour for a total of 6, and just use softened butter. I will also make the cookies smaller.
Yep, just add more flour next time! Thanks for your comment!
From a box? Noway, this doesn’t taste like Crumbl at all sorry
Did you make the cookies?
My spread so much when I made a batch today. How can I stop them from spreading ? they tasted fine but weren’t chewy due to the spreading.
Soo… was I supposed to follow the brownie box direction then add your ingredients? The directions didn’t clearly state that so I did not, looks like several others asked this questions but there was no direct response… my cookies turned out entirely flat; something must have been missing.
Hi Terri. I just recently responded to someone who had this same question, maybe you missed it when you were reading the comments. You were correct, just use the dry brownie mix. You’ll then add the mix-ins listed in the recipe card.
Do you use an oven thermometer? Is your oven heated to 350°F? If it is, the cookies should turn out well. My other suggestion is to add a tablespoon or two of flour.
Have you ever made your own brownie mix before for this recipe? Or just a box mix?
I haven’t. But a friend of mine said they tried this recipe using a homemade brownie mix from the internet, and it didn’t work as well. So I would encourage sticking with a regular box mix.
So do you only use dry brownie mix and add items in recipe…. or do you make brownie mix first and then add items in recipe?
Use the dry brownie mix, then add the ingredients listed in the recipe card
My batter turned out… thick. Haha I don’t know how else to describe it. My blender straight stopped blending because it was so thick. I followed the instructions you listed but clearly messed up… was I supposed to make the boxed brownies like normal (per the box instructions) THEN add in the extras you listed and blend?
Consensus: batter DELICIOUS, and the cookie (even with the chef error) DELICIOUS. Just grab milk and you will be in a chocolate coma.
Did you use a smoothie blender? Because it should be a hand mixer, not a smoothie type blender 🙂
I used a hand mixer, which again causing me confusion on where I messed up ha!
Fantastic. We ate them with fresh raspberries. Perfect texture and taste. This recipe will definitely be in rotation. Thank you.
What brownies did you choose? Did you use the ingredients listed on that brownie box, or just the brownie dry mix and the extras Whitney has listed? Mine are off, but still good. I want to try again though!
First, I would probably only eat Ghirardelli box brownies. Second, I think the reason these brownie COOKIES turned out so fudgey had some help from those box brownies. They had the crackly tops and I always use Dutch cocoa when making brownies. These had everything you would want in a cookie. Loved by all.
Thanks Whitney for another crumbl delight. They are sitting in my freezer so I don’t eat them all at once.
Great recipes
These are perfection! My whole family loved them!
This was meant to be 5 stars!
Fudge, moist, delicious! Tastes just like a brownie but…it’s a cookie. Loved it!
I love that these cookies are ACTUALLY fudgy on the inside. All the other brownie cookies I found online looked SO dry. Not these! I will definitely be making these again!
