I am not really a dessert person. I am all about that salty life. But at the beginning of quarantine this year, I discovered Domino's Marble Brownie Cookie and I have to tell you, my life was changed. If you're on the fence about trying this recipe out, start there. They're cheap and delicious. Then you'll be fully on board with making your own brookies (brownie + cookie). But if maybe chocolate isn't your thing, then check out my Sopapilla Cheesecake!
This recipe is also for you if you're the kind of person that undercooks your brownies or likes cookie dough better than cookies. Baking this all together and filling up the pan means that you're going to get a deliciously gooey dessert bar. Personally I typically find brownies to be too rich for me and whenever I eat a chocolate chip cookie I really just wish it was still in dough form. The best cookies to me are the ones that are huge and chewy. Brookies are the best because the cookies tone down the richness and the cookies aren't overdone!
Tools You Need
One of my favorite parts about brookies is that they are relatively easy to throw together. When I want dessert I usually want it right now. These suggestions are to give you less hassle from start to finish.
Notes: While you could totally use a stand mixer, I have found that this is a bit overkill. A simple hand mixer will do. You could also absolutely use a whisk, it's just a lot of arm power! Do NOT use wax paper instead of parchment paper. Parchment paper is meant to create a non-stick surface so you can pop those marbled brownie cookies out to cut. You should not cook with wax paper. I really love these mixing bowls because you don't need to be afraid of breaking them with the mixer. Plus, they have a silicone bottom so they don't move around when mixing.
You can totally make whatever brownie batter you like the best. Want to make a batter from scratch? Go for it. I think this recipe from What Sarah Bakes sounds amazing! In terms of boxed brownie mixes, I know a lot of people love the Ghirardelli Triple Chocolate Brownies, but I really love the Betty Crocker Milk Chocolate brownie mix. Sure I might try and make brownies from scratch one day, but for a quick and easy dessert this is my go to.
With the cookies however, I really think you ought to make them from scratch! The recipe on the back of the Nestle Toll House Semi-Sweet chocolate chips is the one my grandmother uses. We recently noticed that the recipe updated to call for an additional 2-3 tablespoons of flour and BOY does it make a difference. The biggest tip I can give you here is really spend time creaming the butter. Beat the sugar and butter together until it is very creamy.
Top Tips for Best Brookies
When I first started trying to replicate the marbled brownie from Domino's I was trying to get the cookies to be perfectly placed in the brownie so it was a perfect circle. This lead me to pour the brownie batter in first and then use an ice cream scoop to dole out perfect scoops of dough. This led to there being brownie in every bit but not enough cookie. I then tried putting in the cookie dough first and that was the ticket. You'll get large chunks of cookie next to large chunks of brown which makes every bite taste a little different.
Use ALL the cookie dough that you make. Don't worry about them being too close together. You are going to want the cookie and brownie to play equal parts. You can carefully place the brownie batter around each hunk of dough, but I tend to just pour the whole thing over the top and spread it around evenly. Much easier!
When you take it out REALLY matters for the consistency at the end! If you are wanting more gooey texture, then take it out at the 30 minute mark. If you cut into it now it will not hold its shape and it will pour into the pan. Let it cool completely so that it can finish cooking and solidify. If you're wanting a more cooked brookie then cook it for 45 minutes or until a toothpick comes out clean. Let cool before cutting.
When I made brookies for my family the entire batch was gone in 48 hours. Half was gone in 12. Make these according to your taste and don't be afraid to try out different kinds of cookie! I particularly think snickerdoodle cookies would work exceptionally well for holiday themed brookies. If you make a fun version, let me know! I'm thatzestlife on all social media and I would love to see what you've come up with.
