Between activities for the kids, work, friends, family and church, it seems I am often in need of a dessert that’s perfect for sharing.
My perfectly chewy chocolate chip cookies are always a great standby, but recently I was in the mood for something a little more decadent.
Enter these incredible marbled brownie cookie bars.
The brookie is an amazing dessert because the combination of brownie and cookie brings out the best of both desserts.
You get the richness of the brownie, but it’s toned down a bit by the chewy cookie, so it’s not overwhelmingly chocolaty like brownies sometimes are.
Marbled cookie brownie bars can be made in under an hour.
They taste incredible when they are still just a little warm from the oven, but they also store well, making this marbled cookie brownie recipe one of my favorites for a crowd.
Slice them into just bigger-than-bite-size pieces and pile them on a plate and everyone can dig in. No fork required.
This tasty make-ahead dessert is perfect for game day, too.
Make them in advance and pull them out at halftime because everyone wants something sweet after grazing on finger food for the first half of the game.
Or bring them along as a fantastic potluck dessert to your next gathering!

How to Make Copycat Domino’s Marbled Brownie Cookie Recipe
You may be familiar with Domino’s marbled brownie cookie bars that they sell as a dessert to accompany your favorite pizza.
It’s surprisingly easy to replicate their yummy brownie cookie bars at home, and you can get more bang for your buck that way, too!
But even if you’re not making these for pizza night, they make a great dessert ANY night of the week, in my book! Plus, since it makes a big pan, this is a great recipe for when you have company over.
Ingredients You’ll Need:
For the Brownie Layer:
- Brownie Mix, PLUS the oil, water, and eggs needed to prepare
For the Cookie Layer:
- Butter
- Granulated Sugar
- Brown Sugar
- Egg
- Vanilla Extract
- All-purpose Flour
- Salt
- Baking Powder
- Baking Soda
- Chocolate Chips

How to Make It:
(Full printable recipe is available below)
Mix the brownie layer. First, you’ll make the brownie batter by following the instructions on the box (I love Ghirardelli brownie mix, but you can use whatever you prefer), then spread the batter into a 13×9″ pan.

Make the cookie dough. Next, you’ll make the cookie dough by creaming the butter and sugar until fluffy. Mix in the eggs and then slowly add in the dry ingredients until everything is well combined.
Add the cookie to the brownie. Then you’ll drop spoonfuls of cookie batter all over the brownie batter. Don’t stir or mix them.

Bake and Serve. Last, you’ll cover the pan with foil and bake for 20 minutes. Remove the foil and return to the oven for 20 more minutes until the cookie layer turns golden in color.
Cool completely before serving.

Notes and Adaptations:
- These are much easier to slice when they’re completely cooled, though I know it can be hard to wait! If you want to serve them warm, just know they’ll be a bit more gooey, but still delicious–especially with a scoop of vanilla ice cream!
- Bars can be stored in an airtight container at room temperature for a few days, though they are freshest in the first day or two.

Marbled Brownie Cookie Bars

This dessert is the best of both worlds, as chocolate chip cookies and brownies are marbled together into one delicious "brookie" bar!
Ingredients
- For the Brownie Layer:
- 20-oz package of brownie mix, PLUS the oil, water, and eggs needed to prepare it according to the package instructions
- For the Cookie Layer:
- 1/2 cup butter, softened to room temperature
- 1/3 cup granulated sugar
- 1/3 cup brown sugar, packed
- 1 egg
- 1/2 tsp vanilla extract
- 1 1/4 cup all-purpose flour
- 1/4 tsp salt
- 1/2 tsp baking powder
- 1/4 tsp baking soda
- 1/2 cup chocolate chips
Instructions
- Preheat oven to 350F and grease a 13x9" baking dish.
- Prepare the brownie batter according to the instructions on the box. Pour the batter into the prepared pan.
- Prepare cookie dough by combining butter, granulated sugar, and brown sugar in the bowl of a stand mixer fitted with the paddle attachment. Cream together at medium-high speed until light and fluffy.
- Add egg and vanilla extract, mixing to combine.
- In a separate mixing bowl, whisk together flour, salt, baking powder, and baking soda.
- With the mixer on low speed, gradually add the dry ingredients to the wet ingredients, mixing just until combined and a soft dough forms.
- Add chocolate chips and stir to combine.
- Drop spoonfuls of cookie dough on top of the brownie batter. Do not stir or mix.
- Cover pan tightly with foil and bake for 20 minutes. Remove foil and bake for another 20 minutes, or until cookie dough is a nice golden-brown color.
- Remove from pan and cool completely before cutting.
Notes
- These are much easier to slice when cooled completely, but if you can't wait, you can serve them warm and they'll be a bit more gooey. Top with some vanilla ice cream for an "a la mode" treat!
