How to Make Chocolate Chip Cookie Brownie Bars
Check out how quick and easy it is to make these!
Preheat an oven to 350F and place your rack in the middle. Line a 7x11 glass baking dish with parchment paper, leaving the sides high for easy removal. Set aside.
Make brownie batter in a medium bowl according to the box, and pour into prepared dish (note: you do not have to spread the batter out, it will spread during the next step).
Place lightly flattened pieces of cookie dough and place them throughout the brownie batter. Push them in slightly.
Bake for about 40 minutes or until the brownies are cooked through and the cookies are golden.
Cool in the dish on a cooling rack until fully cooled before removing, then slice and enjoy.
Hint: Pull the bars when the center still looks slightly soft (moist crumbs with the toothpick test), they'll continue to set as they cool for that fudgy brownie texture
Recipe Tips
- Line the Pan: Use parchment paper with a bit of overhang so you can lift the bars out easily and get clean slices.
- Even Layers: Spread the brownie layer evenly before adding the cookie dough so both bake through perfectly.
- Cool Before Cutting: Let them cool for at least 20-30 minutes for clean cuts.
- Mix-In Fun: Add a handful of chocolate chips or chopped candy to the cookie dough for extra chocolatey goodness.

Chocolate Chip Cookie Brownie Bars Recipe FAQs
If you don't have a 7x11 baking dish, use an 8x8 or 9x9 pan instead. Bake a little longer and check doneness with a toothpick, the bars are ready when it comes out with a few moist crumbs.
Spread the brownie layer first, then gently add flattened pieces of cookie dough on top. Lightly press them in before baking, the layers will stay distinct, giving the bars that signature cobblestone look.

This recipe is delicious and moist with a crispy top.
We are happy you liked the textures! Definitely a good one. Thank you for the review.
This is one of my go-to recipes to whip up for the kiddos. We always have refrigerated cookie dough of some type in the house and like to mix up the flavors! So quick and simple.
These were amazing! I tried mine with peanut butter cookie mix and it turned out perfectly.
That is a great sub, peanut butter cookies are so delicious too! Glad you liked them.
The cookie dough is stated in grams. How much in ounces? is this a tub of cookie dough, or a roll that you slice?
Hey Betty, thanks for your question. You can use a roll or a tub and just weigh it out yourself if you want. We used one that was pre-portioned cookies and flattened them lightly as we went along with the recipe. 454 grams is 16 ounces (also a pound). I hope this helps. Happy baking, and please come back and leave us your thoughts after you are done!
WOW! These are amazing. Disappeared lightning fast. Next time I’m making a double batch. We all loved them. Thank you for sharing this amazing recipe!
You are so welcome Sandra! These are a bit hit in our house too.
