Brownie cookies are easy, they’re delicious, they’re oh so chocolatey.
I am straight up obsessed with these cookies. They are so impressive, and so fun. And SO EASY. If you were to take these to a party, I guarantee people would be impressed, and the truth is, they are so easy to make you can bask in the glory, taking all the credit, all while knowing they weren’t any harder to make than a standard chocolate chip cookie.
These delightful cookies are like the marriage between a chocolate cookie and brownie, with a yummy peppermint frosting center. It’s the best combination of all deserts, brownies, cookies, mint. Deciding to share is the hardest part.
Can you make cookies out of brownie mix?
In this recipe I skipped the boxed mix. Everything should be in your pantry so it’s as easy as grabbing the ingredients off the shelf, and you can boast that they are totally homemade. In a pinch you can definitely use a boxed mix though, no shame in that. Some differences between this recipe and boxed brownie cookies to know are:
- You’ll use 2 eggs with a box mix versus the 3 in this recipe.
- Oil is used instead of butter, about 6 tablespoons. (if you want a richer flavor then go with these sandwich cookies)
You’ll want to:
- Make the brownie mix batter and use it as it is. Unless you live at a high altitude then just add about 3 tablespoons extra flour.
- Drop about 2 tablespoons of batter on a cookie sheet about 2 inches apart
- Once the cookies are out of the oven tap the cookie sheet on the counter to let some air out of the cookies to create a nice crackly crust.

How do I ensure my brownie cookies are chewy?
For a cookie you’ll want the texture of your brownie cookie to be more chewy and not so much cakey or fudgy. So tips for ensuring that are:
- Use all purpose flour. This flour has more proteins that help the cookie to hold it’s shape better.
- Don’t over mix the batter.
- Make sure to use whole eggs which help bind the cookie together.
These brownie cookies offer a great texture and an explosion of chocolate, all while adding a layer of fresh cool mint. You’re going to love them.
