Brooksters [Brownie + Cookie]

Brooksters, Brownie and Cookie

You might be wondering what a Brookster is right now.  It’s a mini Brookie.  Which is a brownie cookie.  In other words… delicious.  This ingenious idea is courtesy of those talented Baked boys, Matt Lewis and Renato Poliafito.  I was wandering around William-Sonoma last week when I noticed a box of Brookster mix sitting on the shelf.  I’m not one for purchasing boxed mixes; however, the idea definitely intrigued me.  I just had to recreate it at home.  This Brookster recipe features decadent, golden brown chocolate chip cookies baked atop dense, incredibly chocolatey brownie cups.  The marriage of these two well known confections results in a dessert that is just pure perfection.

An important note about the cooking times and temperatures for this recipe.  I baked several batches of these Brooksters at different times and temperatures to test out various textures and consistencies.  First, I baked the Brooksters at 375 for about 17 minutes.  This resulted in cooked outsides with a molten, fudge-like core.  I baked the next batch at 350 for about 20 minutes and the finished desserts were more evenly cooked through.  I am partial to undercooked brownies, so I definitely preferred the first batch.  For this reason, my instructions below suggest cooking the Brooksters at 375 for 17 – 19 minutes.  If you like your brownies completely cooked, then I would recommend going lower and slower (350 or 325 for 20 – 25 minutes).  Continue reading for the recipe.

Brooksters [Brownie + Cookie]
Adapted from here.
Recipe type: Dessert
Serves: 12 brooksters
  • For the chocolate chip cookie dough:
  • 1 cup plus 2 tablespoons all purpose flour
  • 1/2 teaspoon fine grain sea salt
  • 1/2 teaspoon baking soda
  • 1/2 cup (1 stick) unsalted butter, softened
  • 1/2 cup packed dark brown sugar
  • 1/4 cup white sugar
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 6 oz. semisweet chocolate chips
  • For the brownie batter:
  • 1/2 cup (1 stick) unsalted butter, cut into 1-inch cubes, plus more for muffin tin
  • 3/4 cup all purpose flour
  • 1 tablespoon dark cocoa powder
  • 1/2 teaspoon fine grain sea salt
  • 5 oz. dark chocolate (top quality, 60 to 72 percent cacao), coarsely chopped
  • 3/4 cup white sugar
  • 1/4 cup light brown sugar
  • 3 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  1. To make the chocolate chip cookie dough:
  2. Add flour, fine grain sea salt and baking soda to a large bowl, whisking to combine. Set aside.
  3. In the bowl of an electric mixer fitted with the paddle attachment, mix together butter, white sugar and dark brown sugar on medium speed until smooth and creamy. Using a spatula, scrape down the sides of the bowl. Add the egg and beat until light and fluffy. Add vanilla and mix until just incorporated. Add half of the flour mixture to bowl. Mix for a few seconds on low then increase the speed to medium. Beat until just combined (15 – 20 seconds). Add the remaining flour mixture and repeat the process above. Do not overmix here. Gently fold in the chocolate chips.
  4. Cover bowl, transfer to the refrigerator and chill for at least 3 hours before using.
  5. To make the Brooksters:
  6. Using butter or nonstick spray, grease the bottom and sides of a 12 cup muffin tin. Set aside.
  7. Add flour, fine grain sea salt and cocoa powder to a medium bowl, whisking to combine. Set aside.
  8. Bring a large pot filled with 2 inches of water to a simmer. Set a heatproof bowl on top of the pot, but make sure the bottom of the bowl is not touching the simmering water. Add butter and chocolate to the bowl, stirring until melted and combined. Turn off the heat, but keep the bowl on the pot. Whisk white sugar and light brown sugar into the chocolate mixture. Remove the bowl from the pot and let cool to room temperature.
  9. Add eggs to the chocolate mixture, whisking until just combined. At this point, switch from a whisk to a spatula. You want avoid adding extra air to the batter. Add vanilla and stir until just combined. Gently fold flour mixture into the chocolate mixture until just incorporated. Do not overmix here.
  10. Fill each well of the muffin tin halfway with batter. Transfer muffin tin to the refrigerator and let chill for at least 1 hour. Both the cookie dough and brownie batter must be well chilled before baking to ensure even cooking.
  11. Preheat your oven to 375°F and place a rack in the center of the oven (please see notes above regarding cooking times and temperatures).
  12. Once thoroughly chilled, take the muffin tin from the refrigerator. Using a small spoon, scoop out a small amount of chilled cookie dough. Using your hands, shape dough into ball then slightly flatten it into a disk. The disk should be a bit smaller than the top of the muffin tin wells. Gently press the disk into one of the wells of batter. Repeat this process with remaining 11 wells.*
  13. Place the muffin tin in the oven and bake until the cookies are golden brown ( 17 – 19 minutes), rotating the muffin tin halfway through.
*You will have extra chocolate chip cookie dough leftover. Don’t throw this out. Make cookies. Roll remaining dough into balls. Slightly flatten the balls into disks and place on a cookie sheet lined with a silpat or parchment paper. Bake in a 375 oven until golden brown (9 – 11 minutes depending on the size of your disks). Let cool for a minute on the baking sheet then transfer to a wire rack to cool completely. Or enjoy warm.

    Wow you are my hero…lots of people would used boxed brownie mix and premade refrigerated cookie dough.  You made both from scratch!  NICE!

    • says

      Haha thanks Averie!  I usually don’t cut corners when it comes to baking.  Weeknight dinners… a different story!  I am sure this would work with boxed mix and cookie dough.  Just make sure the brownie batter is nice and chilled before topping with the cold cookie dough.

    Perfect treat and perfect size for my son’s lunch box. I love making homemade treats healthy and decadent ones, it totally makes it special for my boys. I can’t wait to try this out!

    • Kristiwilliams7 says

      Lisa, you will love these.  They are incredible.  I made mine with cupcake liners.  I sprayed the liners with a butter cooking spray before filling them and they came right out of the liners perfectly.  No tearing of the liners at all and the brookies are absolutely decadent!

      I really enjoy immersing myself in the whole baking process.  Measuring, sifting, cracking eggs, etc.  I have also tested many chocolate chip cookie and brownie recipes (paula, thomas keller, alton, baked, epicurious, etc.) and I find the results to be tastier than their box mixed counterparts.  Boxed mixes can be very good (Ghirardelli triple chocolate brownies to name one), but I just enjoy making desserts from scratch.  You should certainly cook or bake in whatever way suits your lifestyle.  As long as you enjoy your time in the kitchen and the results at the end!

    Trust the guy’s at Baked to come up with a recipe like this. They have a talent for creating desserts that our mind’s don’t dare think of. They’re too dangerous. I know the first time I make these (this weekend, I hope), I will have the world at my feet. I mean who can say no to such a creation?

    I am going to try the Lazy Man’s version tonight!  Trader Joe’s bagged ready to pour Brownie Mix and Trader’s ready to go cookie dough.  (I know I shouldn’t admit this to you, but after all would you expect more from me?) 😉
    I will let you know how it goes. 

  5. Tess says

    I got so tickled when I read your “Note” at end of recipe about not throwing out the excess chocolate chip cookie dough!!! That’s never going to happen here either!!! Thanks for the recipe… will be making these for holidays!!! Must “practice” beforehand! lolol

    Made these w/ a few alterations. Chopped bacon bits made it into the brownie batter & sprinkled over the chocolate chip cookie. Filled chocolate truffles in the centers. And a caramel drizzle (to keep the bacon on top from falling off). I concocted it for a halloween party & named them Franken-Brookies, LOL. Everyone LOVED them, and have been asking for more ever since.

  7. says

    I have just made these for my husbands birthday party tonight, a little bit time consuming but well wort it. My daughter has junt had one and loved it. I think they are going to go down well tonight and will by making these more often.

    Does anyone have a suggestion for using a premium boxed brownie mix plus the homemade cookie dough? I just need for it to be a tad easier… 😉

    • Brandon Matzek says

      Hmmm, I usually make everything from scratch 😛 I did have Ghirardelli brownies once that were super tasty, and they came from a boxed mix. I believe the mix is sold at Costco.

  9. Victoria says

    Exactly the band of brownie mix I was thinking of using! I bake and cook mostly from scratch,too, but make exceptions with brownies, Angel food cake, and semolina pasta… 😉

    So, do you think that using this mix might work? I’m willing to experiment!

    • Brandon Matzek says

      I think it should work. Just make sure you chill the brownie batter in the muffin tins before baking. Please let me know how it turns out!!

    Happy National Chocolate Chip Day!
    I’ll be hosting a Toastmasters meeting this evening on this very subject. Best use of chocolate chips are inside cookies.

    My 10 year old son made these last weekend and they turned out great! He’s going to make them again for Thanksgiving. This was his second try at making these. The other recipe he used didn’t work. Refrigerating the dough is key. The only thing he needed help with was shaving the chocolate.

    • Christie says

      We’ve now made these 2 more times. My son did make a gluten-free batch for Thanksgiving using Cup-for-Cup flour. I just made some in a mini muffin pan for a holiday party. I added peppermint extract to the cookies & brownies and used holiday chocolate chips in the cookies. Cooked them about 10 minutes. They were a hit!
