How to store brownie mix cookies?
You want to store these cookies in an airtight container at room temperature, where they will keep for up to 4 days. Just microwave them for a few seconds to get them warm and gooey again before enjoying them.My dough is too thin, help!
This recipe was tested using Duncan Hines dark chocolate fudge brownies, the 2 & 1/2 tbsp of flour work perfectly with this brand of brownies. This recipe also uses a medium/large egg which sits at about 50 grams. If you use an egg that’s bigger than that, your dough will automatically be runnier. If you notice that your batter is too thin, add 1/2-1 tbsp flour. You want the cookie dough to have a playdough texture.Nutrition

I’m commenting again based on my final outcome. These are delicious! I ended up baking them for 17 min in my convection oven and they came out perfect – chewy inside, crisp edges. I did sprinkle with a bit of salt; it looked like it was used in the photos, but wasn’t in the directions. I love sweet and salty. I would make these again, and will just modify baking time.
Great job! Thank you for making the recipe!
Has anyone tried this with oil instead of butter?
Hi Dawn! You can swap the melted butter for an equal amount of neutral oil (like canola or vegetable oil). The cookies will still be fudgy, but they may have a slightly different flavor and a touch less richness compared to butter. If you try it, I’d love to hear how they turn out!
This is the second time I’ve made these – exactly as written. They are perfect!! Fyi – I used Aldi brand brownie mix, chocolate chips and instant coffee because that’s what I had and they are amazing! They freeze well and I just put some in the freezer to have on 4th of July with the family along with homemade ice cream. Thanks so much!
Ooo nice! It’s gonna be a great 4th then ☺
Made this recipe today… I used the exact amounts that the recipe says to us and my dough wasn’t dough. It was still dry like I hadn’t put liquids in it at all. I ended up putting another large egg in and adding a 1/2 cup of melted butter. When I went to scoop the dough, I used a 2 tbsp cookie scoop but wasn’t really sure what size it was until I was done making the balls. (For anyone who isn’t sure what size scoop you have or don’t have a scoop, you can weigh out 1 ounce balls on a food scale.) But the cookies came out delicious and fudgy (I used Ghirardelli double chocolate mix). Not as good as crumbls but it’ll do for now. .
Thanks for sharing your experience, Meagan! Different brownie mix brands can definitely change the dough texture, for example Duncan Hines tends to be moister, while some like Ghirardelli may need more liquid. I’m glad you adjusted and still got fudgy, delicious cookies in the end! And great tip on weighing out 1-ounce dough balls for consistent sizing.
Delicious, but definitely need more flour. At least 1/4-1/3 cup, they are like pancakes otherwise. Much better with more flour. Nice and rounded with more flour.
Thank you for trying out the recipe!
Did you add salt to the tops prior to baking? After? I can’t seem to see this step in the recipe
Hi Dani! I didn’t include flaky salt in the original recipe, but you can absolutely sprinkle some on top, either right before baking (so it bakes in slightly) or immediately after baking (for a more pronounced pop of salt, which is what I did). Both ways work and give that sweet-salty bite!
Yummy! Underbaking is key. The easiest recipe I’ve made in a long time.
Seriously so decadent and delicious!!! The whole family loved them! Will make these again sooo yummy!
How do these turn out if I freeze some dough for another day?
I have never frozen the batter before baking so my guess is that they will spread less.
These were so easy to make and the batch size was perfect for my small family. Currently pregnant and these satisfied every chocolate craving I had. Not too sweet, chewy like a cookie and soft like a brownie.
That sounds wonderful! Glad to hear you enjoy them.
This recipe tasted so yummy but my cookies were very flat and spread out. Do you have any suggestions for me on how I could improve this?
Try adding ½-1 tablespoon flour. On the bottom of the recipe card in the Notes section, I have more information on why the cookies was thin as well 🙂
amazing as always! the best of both worlds brownies and the perfect cookie 🙂
