I don’t know the origins of the brookie (brownie + cookie) but after one of you emailed recently saying you used some of our recipes for brookies, it made me realize we’ve never actually shared a recipe here on Our Best Bites. My quick and easy brookie recipe is a combination of homemade, plus a shortcut. Because while I’m picky about chocolate chip cookies being homemade, I don’t balk at a boxed brownie mix. I’ve had lots of fantastic brownies out of a box and I think in a recipe like this, the box does the trick for me.
So to make this recipe amazingly delicious, but still quick and easy, I use a boxed brownie mix and then top it with a one-bowl easy chocolate chip cookie dough.
If you have a favorite basic brownie recipe, you can certainly sub homemade here. You a 9 x 13 pan full of soft and fudgy brownies layered with buttery chewy chocolate chip cookie. Perfection!
Make your Brookie Brownie Layer
Make your brownies according to the package instructions. I use Ghirardelli brand, and if you look on the back of the box, some brownies have instructions for a 9×13 pan, and some say the largest pan option is 8×8 or 9×9. Try to find one that is made for a smaller pan (the 8×8 or 9×9). You will bake them in a 9×13, thus creating a thinner brownie layer that can complete cooking in the same time as the cookie layer. If you get the larger box, your brownies might be too thick and be undercooked. If all you can find is the larger kind, then maybe make 2 or use half the batter in an extra small pan for a snack 🙂
Make your Brookie Cookie Layer
For the cookie portion of this recipe, I use my Chewy Chocolate Chip Cookie recipe because it uses melted butter, so you can mix the dough with a spoon right in that empty brownie batter bowl. Also 1 batch is the perfect amount for my 9×13 pan.
Bake Your Brookies
It bakes for about 30 minutes and that cookie gets all soft and chewy and the brownie nice and gooey.
You can eat these warm with ice cream on top, but personally I like them cooled if I’m just picking them up to eat.
Layers of flavor give you the best of both worlds!
Pair them with a cold glass of milk and you’ll keep going back for more and more. This recipe is easy and definitely a family favorite at our house. Let me know how you like them!

Brookies
Description
Two beloved desserts come together in one perfect bar cookie.
Ingredients
Brownie Layer:
1 box brownie mix, prepared according to package instructions
(feel free to sub homemade brownie if you prefer!). *SEE NOTE
Cookie Layer:
12 tablespoon butter (1 1/2 sticks) melted and cooled until warm
1 cup brown sugar (light or dark)
1/2 cup granulated sugar
1 large egg plus 1 egg yolk
2 teaspoons vanilla extract
2 cups plus 2 tablespoons flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1 1/2 cups semi-sweet or bittersweet chocolate chips
Instructions
Preheat oven to 325 degrees. Line a 9×13 pan with foil for easy clean-up and spray with non-stick spray.
Prepare brownie mix according to package instructions and pour into prepared pan. Do not bake yet.
In your empty brownie bowl, add melted butter, sugar, brown sugar, egg and yolk, and vanilla an stir to combine. Add flour, soda, and salt and stir. Finally fold in chocolate chips until just mixed.
Use your hands to drop dough onto the top of the brownie batter, it’s okay if some brownie batter shows through.
Bake for 25-30 minutes until cookie part looks set, but not crunchy and brown. You can poke with a skewer or tooth pick to see if the brownie layer is done. You really need to eyeball since all brownie mixes are a little different! I’m using one that is meant to be baked in a slightly smaller pan so if you use a mix meant for a 9×13 it might need a little longer. Cool, cut, and serve.

Can you flip the layers? I think that it would bake better with the brownie mix on top. Your thoughts?
★★★★★
You could certainly try that, but it would most likely bake up in 2 distinct layers instead of being somewhat marbled like this.
About to make this for the 2nd time! We are a dairy free family and not all cookie recipes bake well with dairy free butter. But this is so delicious. I’ll be making them again for a cookie exchange later in the week!

Hello!
I made these and they were delicious but the bottom brownie layer wasn’t done at all. I used a brownie mix for an 8×8 but put it in the 9×13. I cooked it for 35 mins. The cookie was perfect but the brownie wasn’t done at all. Any suggestions? I don’t want to burn the cookie.
All ovens and brownies will cook differently so I would just keep testing and bake until done. You can cover with foil if you feel like your cookies are getting too done!
How many servings does this AWESOME recipe make?
★★★★★
However many you cut 🙂 It’s a 9×13 pan so cut them as you like!
I love that you give recipes with shortcuts like this! Still tastes homemade, but the brownie mix makes it so much easier to whip these out. I made these with the Betty Crocker Fudge brownie mix (recommended for 9×13 pan) cause that’s what I had on hand. I cooked it for 33 minutes and the cookie top and corner piece I sampled were perfect. Took them to a church barbecue, and they were the first dessert to go! I tried a center piece at the party, and the brownie bottom was a little on the gooey side, so next time I will bake a few minutes more.

These were delicious! And easy to make!
This looks great – Aldi have the best box brownie!
I cannot *wait* to make this for our next potluck!!! Thank you for sharing. I do have a favorite brownie recipe, but I think I’ll use a box this time, as it would be that much easier 🙂
So I had the same issue. My brownies were the ghirardelli ones from costco. They are supposed to cook 45-50 mins in a 8×8 pan. I tried it with the brookies in a 9×13. After 30 mins the brownies were still total goo. I kept cooking, but the cookie part was getting overcooked. I ended up taking them out and just eating the cookie top. The edges of the pan were a little more done, so I did get some brookies and they were really yummy. Next time I’ll probably cook the brownies for 20 mins before adding in the cookie part.
Yum this looks delicious!! Our brownie box says to bake the brownies for 50 minutes. In this recipe, bake time is only 30. Will my brownies bake before my cookie layer burns? Or should I bake them a little beforehand?
Is it 50 minutes for a 9×13 or an 8×8? Usually that bake time is for an 8×8 so in a 9×13 it’s about half that time. You’ll honestly have to experiment, mine have always turned out great!
So you said to start the cookie dough In the empty brownie bowl. So do you mean to not wash it?
correct!
These sound AMAZING!! I will definitely have to make them and SOON!
