Ingredients

Gather these simple ingredients to create your extraordinary Brookies. You will need separate sets for the brownie and cookie layers.

FOR THE BROWNIE BATTER

  • 1/2 cup unsalted butter melted (113g)
  • ¾ cup semisweet chocolate chips or roughly chopped chocolate
  • 1/2 cup granulated sugar (100g)
  • 1/2 cup packed light brown sugar (100g)
  • ⅓ cup cocoa powder (35g)
  • 1 teaspoon vanilla extract (5ml)
  • ½ teaspoon salt
  • 2 large eggs
  • 1/2 cup all-purpose flour (65g)

FOR THE COOKIE DOUGH

  • 1/2 cup unsalted butter room temperature (113g)
  • 1/2 cup granulated sugar (100g)
  • 1/4 cup packed light brown sugar (50g)
  • 1 teaspoon vanilla extract
  • 1 large egg
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1 1/3 cups all-purpose flour (160g)
  • 1 cup semi-sweet chocolate chips

Notes & Substitutions

Unsalted butter lets you control the salt content in your baking; if using salted, reduce the added salt by ¼ teaspoon per layer. Use high-quality semisweet chocolate chips for the best flavor in your Brookies, or experiment with milk or dark chocolate. Good quality cocoa powder significantly enhances the brownie layer’s depth.

For a gluten-free option, use a 1:1 gluten-free baking flour blend in both layers. Dairy-free butter sticks work well as a substitute if you prefer a dairy-free dessert.

Equipment

You only need a few basic tools to prepare this fantastic dessert.

  • 9×13 inch baking dish
  • Parchment paper or aluminum foil
  • Mixing bowls (at least two)
  • Whisk
  • Rubber spatula
  • Electric mixer (stand or hand mixer)

Instructions

Creating your amazing Brookies is a straightforward process. Follow these steps for perfect results every time.

  • First, preheat your oven to 350°F (175°C) and line a 9×13 inch baking dish with parchment paper or foil, leaving an overhang on the sides for easy removal later. This prevents sticking and makes cutting simple.
  • For the Brownie Layer:
  • Melt the unsalted butter in a microwave-safe bowl or small saucepan. Once melted, stir in the cocoa powder until fully combined and smooth. Next, whisk in both the granulated sugar, light brown sugar, and salt into the butter mixture. Continue whisking until well incorporated.
  • Add the large eggs and vanilla extract, then beat the mixture vigorously for a couple of minutes until it becomes light in color and glossy.
  • This step is key for creating beautifully fudgy brownies. Gently add the all-purpose flour to the wet ingredients. Mix until the flour is almost combined, then fold in the semisweet chocolate chips using a rubber spatula. Finish mixing the batter by hand, scraping down the sides of the bowl to ensure no dry streaks remain. Transfer this rich brownie batter to your prepared 9×13 pan. Spread it evenly into a thin layer using your spatula, then set it aside while you prepare the cookie dough.
  • For the Cookie Layer:
  • In a large mixing bowl, using an electric mixer, cream together the room temperature unsalted butter, granulated sugar, and light brown sugar. Beat on high speed for 3-4 minutes until the mixture is light, fluffy, and pale in color. Remember to scrape down the sides of the bowl as needed to ensure everything combines thoroughly.
  • Mix in the vanilla extract and the large egg until just combined, scraping the bowl down one more time. In a separate small bowl, whisk together the salt, baking powder, and baking soda. Add these dry ingredients to the wet mixture and mix until just combined. Gradually pour in the all-purpose flour.
  • Mix until the flour is almost fully incorporated. Now, fold in the cup of semi-sweet chocolate chips, reserving a small handful to sprinkle on top before baking. Finish mixing the cookie dough by hand with your spatula.
  • Assembling and Baking Your Brookies:
  • Drop spoonfuls of the prepared cookie dough onto the brownie batter layer in the baking dish. You do not need to spread the cookie dough completely; it is visually appealing to see parts of the brownie layer peeking through after baking.
  • Sprinkle the reserved chocolate chips over the top of the cookie dough. Cover the baking dish loosely with aluminum foil.
  • Bake for 20 minutes at 350°F (175°C). After 20 minutes, remove the foil and continue baking for another 20 minutes, or until the edges are set and a toothpick inserted into the brownie layer comes out with moist crumbs, not wet batter. The cookie layer might still look soft. Allow your amazing Brookies to cool completely in the pan on a wire rack before attempting to remove them or cut into squares. This cooling process is crucial for perfect bars.

Pro Tips & Troubleshooting

  • Achieving perfectly baked Brookies is simple with a few smart techniques. Vigorously beating the eggs and sugars for the brownie batter creates a glossy, crackly top and ensures a fudgy texture. For the cookie dough, make sure your butter is at room temperature; this allows it to cream properly with the sugars, creating a light and airy texture.
  • Avoid overmixing either batter once flour is added, as this can lead to tough results. To check if your Brookies are done, look for set edges and a slight jiggle in the center; a toothpick inserted into the brownie layer should come out with moist crumbs, not raw batter. If your brookies seem dry, you might have overbaked them slightly. If they are too gooey, they likely need a few more minutes in the oven. Reserving a handful of chocolate chips to sprinkle on top before baking adds a beautiful finishing touch.

Understanding the science behind how ingredients interact during baking can help you master these techniques for consistent, delicious results.

Serving, Storage, & Variations

These delicious brookie squares are fantastic served warm with a scoop of vanilla bean ice cream or a cold glass of milk. For storage, keep them in an airtight container at room temperature for up to 3-4 days. To freeze, individually wrap cooled squares tightly in plastic wrap, then place them in a freezer-safe bag or container.

They will last for up to 3 months. Thaw frozen Brookies at room temperature or warm briefly in the microwave. Get creative with flavor variations! Add chopped nuts like walnuts or pecans to either layer, a sprinkle of sea salt on top, or a dash of orange zest for brightness. Experiment with different chocolate types, using white chocolate chips in the cookie layer or dark chocolate for an extra rich brownie.

Instructions
 

  • Line a 9×13 baking dish with parchment paper or foil, then preheat your oven to 350°F (175°C).

For the Brownie Batter

  • Melt the butter for the brownies, then stir in the cocoa powder. Whisk in both granulated and brown sugar along with the salt, then add the eggs and vanilla extract, beating thoroughly for glossy brownies.
  • Mix in the flour until just combined, then gently fold in the chocolate chips. Finish mixing the batter by hand with a spatula, scraping the bowl to ensure everything is well incorporated.
  • Spread the brownie batter evenly into the prepared baking dish and set it aside.

For the Cookie Dough

  • For the cookie dough, cream the softened butter and both sugars on high speed for 3-4 minutes until the mixture is light and fluffy, scraping down the bowl as necessary.
  • Add the vanilla extract and the egg, mixing until just combined, then scrape down the bowl again.
  • Incorporate the salt, baking soda, and baking powder, mixing until they are fully combined.
  • Gradually add the flour, mixing until nearly combined. Fold in most of the chocolate chips, reserving a handful for later, then drop spoonfuls of cookie dough over the brownie batter, allowing some brownie to show through.

Baking

  • Cover the dish with foil and bake at 350°F (175°C) for 20 minutes, then remove the foil and bake for an additional 20 minutes. Let the brookies cool completely before removing them from the pan and cutting into squares.

Notes

For glossy brownies, make sure to beat the eggs and sugar very well. When adding the cookie dough, it’s okay if it doesn’t fully cover the brownie layer; seeing the brownie peek through after baking adds to the aesthetic. Remember to allow the brookies to cool completely before removing and cutting for the best results.
