This fudgy chewy brookies recipe combines the best of two worlds—cookies and brownies—in one irresistible dessert. The contrast between the chewy chocolate chip cookie base and the rich, fudgy brownie top creates a texture and flavor combination that's simply magical.
I first made these brookies for my nephew's birthday party when I couldn't decide between cookies or brownies. The look on everyone's faces when they bit into these two-in-one treats convinced me this would become my signature dessert for gatherings.

Step-by-Step Instructions
- Preheat the Oven
- Set your oven to 350°F and prepare your baking pan. Using parchment paper with overhanging edges makes removal much easier later. Make sure the oven is fully preheated before baking to ensure even cooking throughout.
- Make the Cookie Dough
- Whisk the dry ingredients first to ensure even distribution of leavening agents. When creaming the butter and sugars beat for a full 3 minutes until truly light and fluffy this creates air pockets for the perfect texture. Add the egg and vanilla and mix just until incorporated. Fold in the dry ingredients gently stopping as soon as no flour streaks remain. Overmixing will develop gluten making your cookies tough.
- Make the Brownie Batter
- The melted butter is crucial for the fudgy texture we want. Whisk vigorously when adding the sugar and butter to help create that shiny crackly top brownies are famous for. Add eggs one at a time mixing well between additions. Sifting the cocoa powder prevents lumps and ensures a smooth batter. Fold in the dry ingredients gently just until combined.
- Assemble the Brookies
- Press the cookie dough evenly into the pan using slightly damp fingers to prevent sticking. Take your time spreading the brownie batter over the cookie layer using a spatula or the back of a spoon. Be gentle to avoid mixing the layers together too much some marbling is fine but distinct layers create the signature brookie effect.
- Bake the Brookies
- Position the pan in the center of the oven for even heat distribution. Start checking at 25 minutes but expect 30-35 minutes total. The edges will pull away slightly from the pan when done. Remember that brookies will continue cooking slightly after removal from the oven so a few moist crumbs on your toothpick are perfect.

The brown sugar in the cookie layer is my absolute favorite ingredient in this recipe. I once tried making these with all granulated sugar and they just weren't the same. The moisture and subtle molasses flavor from brown sugar creates that perfect chewy texture that keeps everyone coming back for more.
Storage Tips
These brookies stay fresh in an airtight container at room temperature for up to 3 days. For longer storage place them in the refrigerator where they'll last for about a week. For the best texture let refrigerated brookies come to room temperature before serving. You can also freeze individual squares wrapped in plastic wrap then placed in a freezer bag for up to 3 months. Thaw at room temperature or microwave for 15-20 seconds for that fresh-baked taste.
Mix-in Variations
The basic brookie recipe is delicious on its own but customizing with mix-ins takes them to another level. Try white chocolate chips and macadamia nuts in the cookie layer with dark chocolate chips in the brownie layer for a beautiful contrast. Peanut butter chips create an amazing flavor combination with the chocolate. For a festive touch add colored sprinkles or M&Ms to the cookie layer and mint chips to the brownie layer during holidays. Just be careful not to add too many mix-ins which can prevent proper baking.
Serving Suggestions
While these brookies are perfect on their own they become an extraordinary dessert when served warm with a scoop of vanilla ice cream. The contrast between warm brookies and cold ice cream creates a magical experience. For an impressive dessert platter serve brookies with fresh berries and a dusting of powdered sugar. At parties cut them into smaller bite-sized squares and arrange on a tiered dessert stand. For the ultimate indulgence warm slightly and drizzle with homemade caramel or chocolate sauce.
Recipe FAQs
- → How do I know when my brookies are done baking?
Your brookies are done when a toothpick inserted in the center comes out mostly clean with a few crumbs. The cookie layer should be golden around the edges, while the brownie layer remains fudgy. This typically takes 30-35 minutes at 350°F (175°C).
- → Can I make brookies ahead of time?
Yes! Brookies can be made 1-2 days ahead and stored in an airtight container at room temperature. For longer storage, wrap individual pieces in plastic wrap and freeze for up to 3 months.
- → Why are my brookies too dry?
Overbaking is the most common cause of dry brookies. Remember that they continue cooking slightly as they cool. Also, accurate flour measurement is crucial - try using a kitchen scale or the spoon-and-level method rather than scooping directly with measuring cups.
- → Can I add other mix-ins to my brookies?
Absolutely! Try white chocolate chips, chopped nuts, peanut butter chips, or even crushed candy pieces. You can add different mix-ins to each layer for more variety.
- → How should I cut brookies for the cleanest slices?
For neat slices, allow brookies to cool completely. Use a sharp knife, cleaning the blade between cuts. For extra precision, refrigerate for 30 minutes before slicing or use a plastic knife which surprisingly cuts through gooey desserts cleanly.
- → Can I double this brookie recipe?
Yes, you can double the recipe and bake in a 9×13-inch pan. You may need to increase the baking time by 5-10 minutes, but still use the toothpick test to determine doneness.
