Brownie Mix Cookies is an easy recipe to make and all you need is a 20 oz box of brownie mix, vegetable oil, eggs, extra flour (super important!) and some chocolate chips! All this comes together to give you ultra fudgy brownie cookies that have a crinkly top, gooey center, and set bottoms for the ultimate brownie cookie! 

Brownie Mix Cookies will remind you of your favorite brownies! You can make bakery style (larger) brownie mix cookies with my Brownie Batter Cookies. Or try my Walnut Brownie Cookies or Cosmic Brownie Cookies that take a cookie spin on your favorite brownie recipes.

Why This Recipe Works

  • Gooey brownie centers.  I love that the bottom of the cookies are baked but the centers stay fudgy just like a brownie!!!
  • Ghirardelli brownie mix cookies. I’m a huge sucker for brownies — and brownie mix. You can ask anyone in my family. I love licking the brownie batter leftover on the spoon and bowl, and I love the fudgy goodness of brownies. So, when I found out it was easy to make the best brownie mix cookies from Ghirardelli brownie mix (or any brownie mix for that matter), I was SOLD! 
  • Brownie cookies from mix. The best part of these brownie box cookies is all you need is a brownie mix and a few extra simple ingredients!

Ingredient Notes

  • Dry Brownie Mix: I love the Ghirardelli brownie mix and usually buy the large box at Costco. You only need the dry mix for this brownie mix cookie recipe. Disregard any of the additional ingredients called for on the back of the boxed brownie mix. Please only use the extra ingredients called for in this brownie mix cookies recipe! This is an easy brownie mix cookies recipe thanks to using a boxed mix. 
  • Flour: We add additional flour to the mixture so we get a cookie dough consistency instead of a brownie batter consistency. This will help provide the cookie form. 
  • Vegetable Oil: The vegetable oil gives a moist texture in baking. Usually cookies use butter as the fat, but this recipe uses vegetable oil because we are trying to mimic the brownie texture (and brownies are made with vegetable oil). 
  • Eggs: Our baking binding agent. 
  • Mini Chocolate Chips: Some brownie mixes have chocolate chips in them already. If that’s the case, you can skip this ingredient. Or add more! Can also use regular sized chocolate chips if you’d like.

Step-by-Step Instructions

  1. Combine all the ingredients. Preheat your oven to 375ºF. Line a cookie sheet with parchment paper and set aside. To a large bowl, add the 20 oz dry brownie box mix (see recipe tips for details on if your brownie mix is less than 20 oz), 1/4 cup all-purpose flour, 1/4 cup vegetable oil, 2 eggs, and 1/2 cup chocolate chips. Using a hand mixer, beat until combined. 
  1. Scoop into balls. Using a 2 T cookie scoop, scoop the dough and drop onto the prepared baking sheet, leaving 2 inches between each cookie dough ball.

  1. Bake the Ghirardelli brownie cookies. Place the baking sheet in the preheated oven and bake for 8-10 minutes. The cookies are done when the edges are set but the centers still look doughy. Remove them from the oven and let sit on the baking sheet for 3 minutes. Then transfer to a wire rack to cool completely. Enjoy as is or with a scoop of ice cream!

Recipe Tips

**If you use a brownie mix that is not 20 oz, add enough flour to the brownie mix until it equals 20 ounces. IMPORTANT:  you will STILL need to add the additional 1/4 cup of flour called for in this recipe. That is in additional to the 20 oz dry brownie mix. 

NOTE: you do NOT use the ingredients listed on the box. Please only use the additional ingredients listed in this recipe! 

Using the cookie scoop will help in portioning the dough balls. Although this is a cookie dough, it is still brownie-like, meaning the dough is softer than most cookie doughs so you won’t really have the texture to roll into balls of dough with your hands (because we are going for fudgy brownie-like cookies AKA gooey in the center). 

I used a size 40 cookie scoop and spaced the dough balls 2 inches apart from each other. 

Don’t over bake the cookies! Over baking will make the cookies dry and you won’t have that chewy fudge center. (I sent this recipe to my sister and she baked them for a few minutes longer and she said the cookies were dry and not at all fudgy like brownies. Don’t say I didn’t warn you!) 

To get fudgy cookies, you want the edges to look set but the centers will look doughy. That is the key to the perfect cookie! The centers will look doughy and not fully done. As long as the edges are set, they are done. If you pull the cookies out and the centers look baked, you won’t get the fudgy center.   

Let the cookies sit on the baking sheet for 3 minutes. This will help them set so the bottoms of the cookies are set and you can easily transfer the brownie cookies to a wire rack to cool completely.

Let the cookies cool completely. This will help the bottoms of the cookies to set completely so you can pick them up.

If you don’t have a hand mixer you can use a wooden spoon and just mix until everything is evenly combined. Or feel free to use a stand mixer if you have one.

Variations

  • Create fun variations of brownie mix cookies by adding peanut butter chips, white chocolate chips, mint chips, butterscotch chips or M&Ms to the batter for different flavors. 
  • Add chopped nuts (of any variety) for an additional crunch or variation.
  • Roll the dough balls in powdered sugar for a crinkle cookie effect.
  • Eat plain or pair with vanilla ice cream or make into ice cream sandwiches.  

Make Ahead, Storing, and Freezing

Store in an airtight container or ziplock bag for 3-5 days. I love eating them fresh though! Right off the cookie sheet so they are still a bit warm and gooey … yum!

To freeze, bake as directed and then freeze in an airtight container or freezer-safe bag. Will keep for 1-2 months in the freezer. Thaw before eating. I don’t know how the fudgy centers will do in the freezer/thawing process as I haven’t frozen these cookies yet. We usually eat them within 1 day (totally serious!!)

Recipe FAQs

Can you freeze brownie mix cookies?

Yes! Follow the recipe as directed, let the cookies cool, and then freeze in a ziplock bag for 1-2 months. I haven’t personally frozen these cookies before since usually my family eats them all the day I make them! So, I’m not sure if the gooey, fudgy nature of the cookies will be unaffected after being frozen and thawed. If you do freeze them, let me know how they turn out!

Can you make brownie mix cookies with peanut butter?

If you want to add peanut butter, I suggest stirring in peanut butter chips. This will give you bursts of peanut butter in every bite.

Do I need to use the ingredients listed on the brownie box?

No! In fact, if you add those ingredients, the brownie mix cookies won’t turn out. You only need the DRY brownie mix.  

I followed the recipe, but my cookies didn’t turn out. What did I do wrong?

There could be a few reasons why the cookies didn’t turn out. The first things to look for is to make sure your oven temperature is accurate. Most ovens run a few degrees cooler or hotter than what it says. I use an oven thermometer to make sure my temperature is correct. Then, make sure you are baking cookies in the center rack of the oven. Adjust the racks as needed. Finally, be sure to fluff your flour before measuring. And with this recipe in particular, make sure your brownie mix is 20 oz. If it isn’t, then add additional flour until the brownie mix comes in at 20 oz (use a kitchen scale). THEN you still add the 1/4 cup flour to the bowl. This additional flour will help provide a cookie dough consistency. 

My cookies are dry. What did I do wrong?

You may have baked the cookies for an extra minute too long. Remove the cookies from the oven when the edges are st but the centers still look gooey. Once they set (rest on the pan for 3 minutes) and then cool completely on a wire rack, they will be perfect!
