If you’re unfamiliar, Brookies are the ultimate fusion of two beloved treats: brownies and cookies.
Imagine biting into a rich, fudgy brownie only to be greeted by a soft, chewy cookie layer.
It’s the best of both worlds, and it’s no wonder that this hybrid dessert has gained a cult following.
In this article, we’re going to dive into the process of making Brookies from scratch.
We’ll start with the basics—the ingredients—then move on to the step-by-step instructions to ensure your Brookies come out perfect every time.
Ingredients: What You’ll Need
Before we jump into the process, let’s gather all the ingredients you’ll need for this recipe.
Here’s what you’ll need for both the cookie dough and brownie batter:
Cookie Dough
- 2 1/4 cups all-purpose flour (270g)
- 1 tsp baking soda
- 1 1/2 tsp cornstarch
- 1/2 tsp salt
- 3/4 cup unsalted butter, melted and cooled (170g)
- 1/2 cup granulated sugar (100g)
- 2/3 cup light brown sugar, packed (142g)
- 1 egg + 1 egg yolk, room temperature
- 2 tsp vanilla extract
- 1 cup semi-sweet chocolate chips (170g)
Brownie Batter
- 3/4 cup all-purpose flour (90g)
- 1/2 cup unsweetened cocoa powder (50g)
- 1/2 tsp salt
- 3/4 cup unsalted butter, cold and diced (170g)
- 2/3 cup semi-sweet chocolate chips (113g)
- 1/2 cup granulated sugar (100g)
- 2/3 cup light brown sugar, packed (142g)
- 2 eggs + 1 egg yolk, room temperature
- 1 tsp vanilla extract
Now that you have all your ingredients ready, let’s move on to the preparation.
Making Brookies isn’t complicated, but it does require some attention to detail.
Follow each step carefully to ensure your final product is as delicious as possible.
Step 1: Preparing the Cookie Dough
Start by preparing the cookie dough.
This dough will form the cookie layer of your Brookies, so you want to make sure it’s rich and flavorful.
- Melt the Butter
Begin by melting 3/4 cup of unsalted butter in a microwave-safe bowl. To do this, place the bowl in the microwave and heat in 20-second intervals. Stir the butter between each interval until it’s fully melted. Once melted, set it aside to cool slightly—you don’t want to add hot butter to your other ingredients as it might cook the eggs. - Mix the Dry Ingredients
In a medium bowl, combine 2 1/4 cups of all-purpose flour, 1 tsp of baking soda, 1 1/2 tsp of cornstarch, and 1/2 tsp of salt. Whisk these ingredients together until well combined and then set the bowl aside. - Cream the Sugars with Butter
In a large mixing bowl, add the cooled melted butter along with 1/2 cup of granulated sugar and 2/3 cup of light brown sugar. Beat these ingredients together for about 2 minutes until the mixture becomes light and fluffy, resembling a thick paste. - Add the Eggs and Vanilla
Next, add 1 egg and 1 egg yolk (both at room temperature) to the sugar and butter mixture, along with 2 tsp of vanilla extract. Mix until everything is well combined and the dough starts to come together. - Incorporate the Dry Ingredients
Slowly add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix; you want the dough to be soft but not tough. - Fold in the Chocolate Chips
Finally, fold in 1 cup of semi-sweet chocolate chips. The dough should be thick and studded with chocolate chips throughout. Set the dough aside as you move on to preparing the brownie batter.
Step 2: Preparing the Brownie Batter
The brownie layer of the Brookies is equally important, providing a rich, chocolatey base for the cookie dough.
Follow these steps to create a decadent brownie batter that will complement your cookie dough perfectly.
- Mix the Dry Ingredients
In a medium bowl, whisk together 3/4 cup of all-purpose flour, 1/2 cup of unsweetened cocoa powder, and 1/2 tsp of salt. Set this mixture aside for later. - Melt the Butter and Chocolate Chips
In a heat-proof bowl, combine 3/4 cup of cold, diced unsalted butter and 2/3 cup of semi-sweet chocolate chips. Melt the mixture using a double boiler method or by microwaving in 20-second intervals, stirring between each interval until fully melted. Once melted, set it aside to cool slightly. - Beat the Eggs and Sugars
In a large mixing bowl, beat together 2 eggs, 1 egg yolk, 1/2 cup of granulated sugar, and 2/3 cup of light brown sugar until the mixture is light and frothy. This will take about 2-3 minutes of vigorous beating to achieve the right texture. - Combine the Wet Ingredients
Add the melted chocolate and butter mixture to the beaten eggs and sugars, along with 1 tsp of vanilla extract. Mix until everything is fully combined and the batter is smooth. - Fold in the Dry Ingredients
Gradually add the dry ingredients to the wet mixture, folding gently until just combined. The batter should be thick and glossy—resist the temptation to overmix.
Step 3: Assembling and Baking the Brookies
Now that both your cookie dough and brownie batter are ready, it’s time to combine them into a single, delicious dessert.
Here’s how to assemble and bake your Brookies for the perfect balance of brownie and cookie in every bite.
- Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven heats up, grease a 10×10-inch square baking pan to prevent the Brookies from sticking. - Layer the Brownie Batter
Pour the brownie batter into the prepared baking pan, using a spatula to spread it out evenly. Make sure the entire bottom of the pan is covered with a smooth layer of brownie batter. - Add the Cookie Dough
Using a spoon, drop dollops of cookie dough over the brownie batter. Press the cookie dough lightly into the brownie batter without fully covering it—you want to see both layers distinctly. - Bake the Brookies
Cover the baking pan with aluminum foil and place it in the preheated oven. Bake for 20 minutes with the foil on, then remove the foil and continue baking for an additional 15-20 minutes. The Brookies are done when a toothpick inserted into the center comes out with a few moist crumbs—you don’t want to overbake them. - Cool and Slice
Once baked, remove the Brookies from the oven and let them cool completely in the pan. Cooling is crucial; it allows the Brookies to set properly, making them easier to slice. Once cooled, cut into squares and enjoy!
Tips for Perfect Brookies Every Time
- Use Room Temperature Ingredients: This ensures that the batter and dough mix evenly, resulting in a uniform texture.
- Don’t Overmix: Whether you’re mixing the cookie dough or the brownie batter, be careful not to overmix. Overmixing can lead to tough, dense Brookies instead of soft, chewy ones.
- Cool Completely Before Slicing: It might be tempting to dive right in, but letting the Brookies cool completely will give you cleaner slices and a better overall texture.
Why Brookies Are the Ultimate Treat
Brookies are more than just a dessert—they’re a celebration in every bite. The contrast between the gooey brownie layer and the chewy cookie dough makes for an irresistible combination that’s perfect for any occasion.
Their versatility is another reason to love them; you can customize the recipe by adding nuts, different types of chocolate, or even a swirl of peanut butter or caramel. No matter how you choose to make them, one thing is for sure: Brookies are here to stay as a favorite among dessert lovers.
