I love how this recipe delivers two classic desserts in one pan. The brownie layer stays dense and chocolatey, while the cookie layer adds a buttery, chewy contrast. I also appreciate that it’s straightforward to prepare, even though it looks impressive. These bars are perfect for sharing, and I always find them disappearing quickly.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.)
For the Cookie Dough
¾ cup (170g) unsalted butter, softened ¾ cup (165g) packed light brown sugar ¼ cup + 2 tablespoons (60g) granulated sugar 1 large egg 1 large egg yolk 1 tablespoon (15ml) pure vanilla extract 1 ¾ cups + 2 tablespoons (254g) all-purpose flour ¾ teaspoon salt ¼ + 1/8 teaspoon baking soda 1 cup (180g) chocolate chips
For the Brownie Batter
6 ounces dark chocolate, melted ¾ cup (170g) unsalted butter, melted 1 ½ cups (285g) granulated sugar 3 large eggs 1 large egg yolk 1 tablespoon (15ml) pure vanilla extract ¾ cup (105g) all-purpose flour ¾ cup (84g) cocoa powder, sifted 1 teaspoon salt ¾ teaspoon baking powder
Directions
I start by preheating the oven to 350°F and preparing a 9×13-inch pan with grease and parchment paper. I let the butter soften so it mixes smoothly.
For the cookie dough, I beat the butter with both sugars until creamy, then mix in the egg, egg yolk, and vanilla. In another bowl, I combine the dry ingredients and gradually add them to the dough. Before it fully thickens, I stir in the chocolate chips and set the dough aside.
For the brownie batter, I melt the chocolate until smooth and let it cool slightly. I melt the butter separately and mix it with sugar until combined. Then I add the eggs and extra yolk, beating until the mixture becomes fluffy. I mix in the vanilla and melted chocolate, then fold in the dry ingredients just until combined.
To assemble, I pour the brownie batter into the prepared pan. I take portions of the cookie dough, flatten them slightly, and layer them over the brownie batter until everything is used.
I bake the brookies for 35 to 40 minutes, covering them with foil partway through to prevent over-browning. I check for doneness with a toothpick, making sure the center is fudgy but not wet. I let them cool so they finish setting before slicing.
Servings and Timing
I usually cut these into about 18 to 21 bars. The prep takes around 45 minutes, and the baking time is about 35 to 40 minutes, bringing the total time to roughly 1 hour and 20 minutes.
Variations
I sometimes swap dark chocolate for semi-sweet or milk chocolate depending on the flavor I want. I also like adding chopped nuts or white chocolate chips to the cookie layer. For a richer twist, I mix in chunks of chocolate instead of chips. Occasionally, I add a swirl of peanut butter or caramel to the brownie batter for extra indulgence.
Storage/Reheating
I store the brookies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. When I want them warm and gooey again, I reheat individual pieces in the microwave for a few seconds. They also freeze well, and I thaw them at room temperature before serving.
FAQs
How do I know when brookies are done?
I look for a set top and slightly fudgy center, checking with a toothpick.
Can I use chocolate chips instead of a baking bar?
Yes, I can substitute chocolate chips if needed.
Why is my cookie layer underbaked?
I expect it to be slightly soft, which keeps the texture chewy.
Can I make these ahead of time?
Yes, I often prepare them a day in advance.
What size pan should I use?
I use a 9×13-inch pan for even layers.
Can I freeze brookies?
Yes, I freeze them in layers separated by parchment paper.
How do I prevent sticking?
I grease the pan and line it with parchment paper.
Can I reduce the sugar?
I can slightly reduce it, but it may affect texture and sweetness.
What cocoa powder works best?
I prefer a high-quality cocoa powder for the best flavor.
Can I add mix-ins?
Yes, I like adding nuts, caramel, or extra chocolate pieces.
Conclusion
I love how these brookies bring together the richness of brownies and the chewiness of cookies in one dessert. They’re easy to make, incredibly satisfying, and always a hit when I share them. Whenever I want something extra special, this is the recipe I turn to.
These easy brookies combine a rich, fudgy brownie base with a soft and chewy chocolate chip cookie layer. A perfect indulgent dessert that delivers the best of both worlds in every bite.

Instructions
Preheat the oven to 350°F and prepare a 9×13-inch pan with grease and parchment paper.
In a bowl, beat softened butter with brown sugar and granulated sugar until creamy. Mix in the egg, egg yolk, and vanilla extract.
In another bowl, combine flour, salt, and baking soda. Gradually add to the wet mixture, then fold in chocolate chips to form the cookie dough. Set aside.
Melt the dark chocolate and let it cool slightly. In a separate bowl, mix melted butter with granulated sugar.
Add eggs and egg yolk to the butter mixture and beat until fluffy. Stir in vanilla and melted chocolate.
Fold in flour, cocoa powder, salt, and baking powder until just combined to make the brownie batter.
Pour the brownie batter into the prepared pan and spread evenly.
Flatten portions of cookie dough and layer them over the brownie batter.
Bake for 35–40 minutes, covering with foil partway through to prevent over-browning.
Check doneness with a toothpick; the center should be fudgy but not wet. Allow to cool before slicing and serving.
