Ingredients You’ll Need
- 6 tablespoons (85 grams) unsalted butter: This provides the rich base for both the cookie and brownie layers. Always use unsalted for better control over sweetness.
- 1/2 cup (100 grams) light brown sugar: Adds moisture and a deep caramel flavor. If you’re out, you can substitute with granulated sugar.
- 1/4 cup (50 grams) granulated sugar: Sweetens the cookie dough without overpowering.
- 1 large egg: Binds the cookie mixture together and contributes to the chewy texture.
- 1 teaspoon vanilla extract: Enhances the overall flavor; use pure vanilla for the best results.
- 1 1/4 cups (159 grams) all-purpose flour: Gives structure to the cookie layer. Make sure to measure it correctly for accurate results!
- 1/2 teaspoon fine sea salt: Balances sweetness and enhances flavor.
- 1/4 teaspoon baking powder: Helps the cookies rise slightly without making them cake-like.
- 1/2 cup (95 grams) semisweet chocolate chips: For a melty, chocolatey delight. Milk or dark chocolate can work in a pinch, depending on your preference.
- 4 tablespoons (57 grams) unsalted butter: Also for the brownie layer, providing thickness and richness.
- 3/4 cup plus 2 tablespoons (175 grams) granulated sugar: This makes the brownie base sweet and deliciously fudgy.
- 1 large egg plus 1 egg yolk, cold: The extra yolk helps to make the brownies even more fudgy – who can resist?
- 1/2 cup (43 grams) cocoa powder: Essential for that rich chocolate flavor; Dutch-processed cocoa can lend a darker taste.
- 1/4 cup plus 2 tablespoons (56 grams) neutral oil (like vegetable or avocado): Keeps the brownies moist without a greasy texture.
- 1 teaspoon vanilla extract: Like in the cookie layer, this amplifies the rich flavors.
- 1/4 cup plus 2 tablespoons (48 grams) all-purpose flour: Again, be sure to measure it correctly.
- 2 teaspoons cornstarch: This is a little secret that gives the brownies an ultra-soft texture.
- 1/4 teaspoon fine sea salt: Like always, balance is key!
- 1/2 cup (95 grams) semisweet chocolate chips: Adding more chocolate ensures that every bite lives up to its rich reputation.
- Flaky sea salt, (optional): A sprinkle on top enhances flavor and provides a lovely contrast to the sweetness.
How to Make Brookies
Preheat and Prepare the Pan: Start by preheating your oven to 325°F. Line an 8 by 8-inch metal baking pan with parchment paper, leaving some overhang for later, and give it a light spray with nonstick cooking spray.
Make the Cookie Dough: In a large microwave-safe bowl, melt the butter in 30-second increments until completely liquid. Add the light brown sugar and granulated sugar, whisking to combine until smooth. Allow this mixture to cool until just warm.
Add Egg and Vanilla: Once cooled, whisk in the egg and vanilla extract thoroughly until it’s nicely incorporated.
Incorporate Dry Ingredients: Gently stir in the measured all-purpose flour, fine sea salt, and baking powder with a rubber spatula. Fold in half a cup of semisweet chocolate chips and place the dough in the fridge to chill while you prepare the brownie layer.
Make the Brownie Batter: Again, use a large microwave-safe bowl to melt the butter, just as you did for the cookie dough, in 30-second increments. Mix in the sugar until smooth and let it cool slightly.
Whisk & Combine: Whisk in the cold egg and egg yolk for about a minute, then add the cocoa powder, neutral oil, and vanilla extract. Stir in the all-purpose flour, cornstarch, and salt until just combined. Fold in another half cup of semisweet chocolate chips for that delightful chocolatey goodness.
Assemble the Layers: Now, take out nine tablespoons of the cookie dough and set them aside in a small bowl – these will top your brownies. Spread the remaining cookie dough into the bottom of your prepared pan in an even layer. Don’t worry about perfection; just aim for an even spread!
Layer on the Brownie Batter: Pour that luscious brownie batter over the cookie layer and spread it evenly, coaxing it into all corners so every bite has a bit of everything.
Top with Cookie Balls: Take the reserved cookie dough balls and flatten them slightly; distribute those across the top, letting the brownie batter peek through like a playful surprise.
Bake: Pop your pan into the preheated oven and bake at 325°F for 33-38 minutes. If you prefer a fudgier center, go for 33 minutes, but aim for 38 minutes if you want a chewier texture. The edges will set nicely, and you might see the cookies begin to brown just a bit.
Cool Down: When done, sprinkle with flaky sea salt if you like that sweet-meets-salty touch. Let the brookies cool completely in the pan before transferring to a wire rack for slicing.
Storing & Reheating
To store brookies, keep them in an airtight container at room temperature for up to 3 days to maintain that fresh taste. For longer-term storage, you can refrigerate them for up to a week, or freeze for up to three months. When you’re ready to indulge again, simply reheat in the microwave for about 10-15 seconds to refresh their fudgy goodness. While the texture may slightly change after freezing, they’ll still be delightfully delicious!
Chef’s Helpful Tips
- Measure your flour correctly by using the spoon and level method to avoid dense brookies.
- Room temperature eggs help create a smooth batter, making it easier to combine ingredients.
- Don’t overmix once you add the flour; a gentle stir is key to soft textures.
- Prefer something extra special? Swirl in peanut butter or caramel sauce before baking.
- If you enjoy nuts, adding chopped walnuts or pecans can add a lovely crunch.
Brookies embody the best of both cookies and brownies, making them a stellar dessert bite. Experiment with flavors, like adding a hint of espresso or swapping chocolate chips for white chocolate or nuts. Trust me, the variations are delicious and endless. Every snack is a chance to try something new, so gather your ingredients and indulge in the magic of homemade brookies!

Recipe FAQs

Can I make these brookies gluten-free?
Yes, you can substitute the all-purpose flour with a gluten-free all-purpose blend. Just make sure it includes binding agents like xanthan gum for the best texture.

To get clean slices without crumbling, use a sharp knife and wipe it clean between cuts. You can also chill them in the fridge for an hour before slicing for neat edges.
