Chocolate-Chip Streusel Brownies Ingredients
For the Cookie Dough Streusel:
- 1 stick (8 tablespoons) unsalted butter, room temperature, plus more for pan
- 1 ¾ cups unbleached all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon baking powder
- ¾ teaspoon kosher salt
- ½ cup packed light-brown sugar
- ½ cup granulated sugar
- 1 large egg, room temperature
- 1 teaspoon pure vanilla extract
- 6 ounces bittersweet chocolate, chopped
For the Brownie Batter:
- 1 stick (8 tablespoons) unsalted butter, cut into large pieces
- 6 ounces bittersweet chocolate, chopped
- 1 ½ cups granulated sugar
- 3 large eggs, room temperature
- ¼ cup unsweetened Dutch-process cocoa powder
- ½ teaspoon kosher salt
- ½ cup plus 2 tablespoons unbleached all-purpose flour
How To Make Chocolate-Chip Streusel Brownies
- Prep Oven and Pan: Preheat your oven to 350°F. Brush a 9×13-inch baking pan with butter and line it with parchment paper, leaving an overhang on the long sides to use as handles.
- Make the Cookie Dough: In a large bowl, beat the room temperature butter with both sugars on medium-high speed until light and fluffy, about 6 minutes. Beat in the egg and vanilla. In a separate bowl, whisk the flour, baking soda, baking powder, and salt. On low speed, add the flour mixture to the butter mixture until just incorporated. Stir in the chopped chocolate. Set aside.
- Make the Brownie Batter: In a heatproof bowl set over a pot of simmering water, melt the butter and chocolate, stirring until smooth. Remove from the heat and whisk in the sugar. Whisk in the eggs one at a time, then whisk in the cocoa and salt. Fold in the flour until just combined.
- Assemble and Bake: Pour the brownie batter into the prepared pan and smooth the top. Crumble the cookie dough evenly over the brownie batter.
- Two-Stage Bake: Cover the pan with parchment-lined foil and bake for 20 minutes. Remove the foil and continue baking for another 27 to 30 minutes, until the cookie topping is golden brown and a toothpick inserted into the center comes out with moist crumbs.
- Cool Completely: Let the brownies cool completely in the pan on a wire rack. This is a crucial step for the layers to set. Once cool, use the parchment handles to lift the slab out and cut it into 16 squares.
Recipe Tips
- What is a “brookie”? This dessert, which combines a brownie and a cookie, is often affectionately called a “brookie.”
- How do you know when it’s done? The toothpick test is key. You want the toothpick to come out with moist, fudgy crumbs attached, not wet batter. This ensures the brownie layer is perfectly fudgy and not overbaked.
- Why is cooling completely so important? This is the hardest but most essential step! Cooling allows both the brownie and cookie layers to firm up properly, which is necessary for getting clean, neat slices.
- Can I chill the cookie dough? If your kitchen is warm and the cookie dough feels very soft and sticky, you can chill it for 15-20 minutes before crumbling it over the brownie batter. This will help it hold its shape better.
What To Serve With Chocolate-Chip Streusel Brownies
These decadent bars are a complete dessert on their own, but they are even more indulgent with:
- A tall glass of cold milk
- A scoop of vanilla bean ice cream
- A drizzle of warm caramel or chocolate sauce
How To Store Chocolate-Chip Streusel Brownies
- Room Temperature: Store the brownies in an airtight container at room temperature for up to 3 days.
- Freeze: For longer storage, wrap the cooled brownies individually in plastic wrap, then place them in a freezer-safe bag. They can be frozen for up to 3 months. Thaw at room temperature.

FAQs
Can I use a different size pan?
Yes, but you’ll need to adjust the baking time. For a 9-inch square pan, the layers will be thicker, and you will likely need to add 10-15 minutes to the total baking time.
Can I add nuts?
Absolutely. You can add about ¾ cup of chopped toasted walnuts or pecans to either the brownie batter or the cookie dough for extra crunch.
Why cover the pan for the first part of baking?
Covering the pan for the first 20 minutes allows the brownie layer to set up without the cookie dough topping browning too quickly. Removing the foil for the second half of baking ensures the streusel gets perfectly golden and crisp.
