I’m a chocolate lover. Full stop. And so are my kiddos. Friday nights after Shabbat dinner are dessert night in our house, and while I usually reach for a boxed brownie mix because 1. it’s dairy free and 2. it’s just easy, sometimes I need something a little more fun than the usual square cut brownies. That’s how these brownie mix cookies came to be. 

They’re soft, chewy, and totally fudgy, like the edge piece of a brownie, but in cookie form. We’re talking rich, chocolatey goodness made from a boxed brownie mix, with just a few extra ingredients and way less cleanup.

You probably know by now that I love giving box dessert mixes a little glow-up. If you're not in the mood to turn on the oven, my brownie batter dip is a fun no-bake option that totally hits the spot. And if you're feeling a little swirly, the tahini swirl brownies are a favorite around here, a fun twist on your classic brownie situation.

Ingredients

You’ll only need a few pantry staples to make these fudgy brownie mix cookies come to life:

ingredients for brownie mix cookies
  • 1 box brownie mix - I’ve tested this with both Duncan Hines and Ghirardelli. Use your fave!
  • 2 eggs – Large eggs, as always.
  • ½ cup oil – I use canola or vegetable oil.
  • 2 tablespoons water – To help the batter loosen up just enough.

Step by step instructions

Step 1: Mix it up.
In a large mixing bowl, add the brownie mix, eggs, oil, and water. Stir with a wooden spoon or spatula until everything is just combined. It’ll be thicker than regular brownie batter—don’t worry, that’s what we want!

Step 2: Scoop the dough.
Use a cookie scoop (or a tablespoon) to portion the dough onto a parchment-lined baking sheet. Leave a little space between cookies, they’ll spread just a bit.

Step 3: Bake.
Pop into a preheated oven at 350°F for 9–11 minutes. You want to see a crinkly top but still have soft centers. Don’t overbake!

Step 4: Cool.
Let them rest on the pan while they cool This helps them set before you serve them.

Serving Ideas: These brownie mix cookies are a perfect Shabbat dessert upgrade, serve them warm with a scoop of ice cream or serve up a cookie buffet with funfetti cookies and lemon cake mix cookies. They also make a great lunchbox treat! Just wrap in parchment paper, pop it in the lunchbox and your kiddo gets a sweet surprise when then need it most.

Variations to Try

  • Add-ins: Try chocolate chips, butterscotch chips, chopped nuts, or mini m&m’s.
  • Mint Twist: Use a mint brownie mix and throw in some chopped Andes mints as you are mixing up the batter..
  • Spiced Brownie Cookies: Add a pinch of cinnamon and cayenne to the batter for a Mexican hot chocolate vibe.
  • Cookie Sandwich: Kinda like my chocolate sandwich cookies, but make it a brownie sandwich. Add a spoonful of frosting, marshmallow fluff, or even ice cream between two cookies for a next-level treat.

Storage + Freezing Tips

Storing the cookies: Keep your brownie cookies in an airtight container at room temp for up to 4 days.

Freeze: You can freeze the baked cookies. The cookie dough is so quick to make, I don’t suggest making it and freezing it ahead of time.  The baked (and cooled) cookies can go right into a ziptop bag.  Try to squeeze out as much air as you can to help them stay fresh!

Ingredients
  

  • 1 Boxed Brownie Mix (Duncan Hines Chewy Brownie mix is our preferred brand, with Ghiradelli a close second)
  • 2 eggs
  • ½ cup oil
  • 2 TB water

Instructions
 

  • Preheat your oven to 350 degrees and line a baking tray with parchment paper.
  • In a large mixing bowl, add the brownie mix, eggs, oil and water. Stir just until you can’t see any more dry cake mix, being careful not to overmix.
  • Using a cookie scoop, scoop the cookie dough onto your prepared baking tray, leaving about 2” between dough balls.
  • Bake for 8-10 minutes until you see cracks on the top of the cookies, being careful not to overbake them. Remove from the oven and let cool on the baking tray until set.

Notes

To make brownie sandwich cookies: Let the cookies cool completely before filling.  Then fill with either vanilla frosting or ice cream.  For ice cream, wrap each one individually in plastic wrap, then pop into a zip top bag to freeze.
Freezing Instructions: I suggest baking the cookies as directed and freezing them once baked. They will last in the freezer for up to 2 months.
