Ingredients
Brookies combine fudgy brown butter brownies with chewy chocolate chip cookies! Layering the two batters in a specific way ensures that everything bakes evenly without one layer over baking.
For the Brownie Layer
- 14.5 tbsp salted butter (206 grams)
- 3/4 cup dark brown sugar, packed (163 grams)
- 3/4 cup granulated sugar (156 grams)
- 2 large eggs, at room temperature
- 1 and 1/2 tsp vanilla extract
- 3 cups all-purpose flour, spooned & leveled or weighed out (390 grams)
- 1 tsp baking soda
- 1 tsp baking powder
- 1/2 tsp salt
- 1 and 1/2 cups chocolate chips
For the Cookie Layer
- 3/4 cup salted butter, cubed (170 grams before browning, 140 grams after)
- 4 ounces semi-sweet chocolate, chopped (Chocolate chips work too)
- 1/4 cup vegetable oil (56 mL)
- 3/4 cup cocoa powder (63 grams)
- 3 large eggs, at room temperature
- 1 large egg yolk, at room temperature
- 3/4 cup granulated sugar (158 grams)
- 1 and 1/2 cups powdered sugar (174 grams)
- 2 tsp vanilla extract
- 1/4 tsp salt
- 1/2 cup all-purpose flour (65 grams)
- Pinch of espresso powder (optional)
- 1 cup semi-sweet chocolate chips
- Flaky sea salt, optional
How to Make Brown Butter Brookies
Step 1: Preheat the Oven
Preheat your oven to 350℉. Spray a 9×13 metal pan with nonstick spray and line it with parchment paper. This method makes for easy removal and slicing later on.
Step 2: Make the Chocolate Chip Cookie Dough
- Melt the butter in a large mixing bowl.
- Whisk in the sugars until combined.
- Add eggs and vanilla; whisk until smooth and combined for about 30–45 seconds.
- Stir in dry ingredients followed by chocolate chips or chunks last.
- Divide dough into two equal halves (about 640 grams each).
- Press half of the dough into the prepared pan; lift out that piece of parchment paper and replace it with a new piece. Set cookie dough aside.
Step 3: Brown the Butter
Add cubed butter to a medium saucepan over medium heat.
Melt the butter while stirring occasionally.
Once melted, turn heat to medium-low. Continue cooking while stirring frequently until it turns deep golden with a nutty aroma—a process that takes about 3–6 minutes once melted.
Step 4: Make the Brownie Batter
Once browned:
Stir in semi-sweet chocolate until melted completely.
Whisk in vegetable oil and cocoa powder; set aside to cool slightly.
In another bowl:
Add eggs, egg yolk, and granulated sugar; whisk for about 1–2 minutes until dissolved.
Whisk in powdered sugar, vanilla extract, and salt.
Check that chocolate mixture is warm but not hot; whisk it into egg/sugar mixture.
Fold in flour & espresso powder followed by chocolate chips.
Step 5: Assemble
Spread slightly more than half of the brownie batter in the lined pan. Lay cookie dough on top while removing extra parchment paper. Spread remaining brownie batter over this layer.
Form large discs with leftover cookie dough and set on top of batter. Press extra chocolate chips into bare spots if desired.
Step 6: Bake
Bake assembled brookies for 38 to 44 minutes until cookies are golden and brownies have a shiny top. A toothpick inserted should show moist crumbs but not wet batter—avoid overbaking!
Step 7: Serve & Store
Allow bars to cool in the pan on a wire rack for about 1 – 2 hours before slicing. Sprinkle with flaky sea salt if desired! Store cooled bars in an airtight container at room temperature for up to 3–4 days. For best results when enjoying leftovers, warm slices briefly in the microwave before serving.
How to Serve Brown Butter Brookies
Brown Butter Brookies are a delightful combination of fudgy brownies and chewy chocolate chip cookies. They can be served in various ways to enhance your dessert experience.
With a Scoop of Ice Cream
- Vanilla ice cream pairs perfectly with the rich flavors of the brookies. The cold creaminess balances the warm, gooey texture.
Drizzled with Chocolate Sauce
- A drizzle of warm chocolate sauce adds an extra layer of indulgence. This creates a decadent treat that chocolate lovers will adore.
Topped with Whipped Cream
- Light and airy whipped cream complements the dense brookies nicely. You can add a sprinkle of cocoa powder or chocolate shavings for a fancy touch.
Served with Fresh Berries
- Fresh strawberries or raspberries bring a fruity brightness to each bite. They cut through the richness and add a refreshing contrast.
Accompanied by Milk or Coffee
- A glass of cold milk or a cup of coffee enhances the overall experience. Both drinks provide a comforting balance to the sweet and buttery flavors.

How to Perfect Brown Butter Brookies
To ensure your Brown Butter Brookies turn out perfectly every time, follow these essential tips.
Use Room Temperature Ingredients: Ingredients like eggs and butter mix better when they are at room temperature, leading to a smoother batter.
Do Not Over Mix: When combining ingredients, mix just until incorporated. Overmixing can lead to tough brookies rather than tender ones.
Watch Baking Time Closely: Every oven is different, so start checking your brookies a few minutes before the suggested baking time. You want them set but not dry.
Cool Before Slicing: Allow the brookies to cool completely in the pan before slicing. This helps them maintain their shape and prevents them from falling apart.
Best Side Dishes for Brown Butter Brookies
While Brown Butter Brookies are delicious on their own, pairing them with side dishes can elevate your dessert table even further.
- Vanilla Ice Cream: A classic pairing that enhances the rich flavors of brookies with creamy sweetness.
- Chocolate Mousse: Light and airy, this dessert adds an elegant touch next to your hearty brookies.
- Fruit Salad: A mix of fresh fruits provides a refreshing contrast that balances out the richness.
- Cheesecake Bites: These bite-sized treats offer creaminess that complements the textures of brookies.
- Caramel Sauce: Drizzling warm caramel over your brookies adds another layer of flavor that’s hard to resist.
- Coffee Cake: The lightness of coffee cake contrasts nicely with the density of baker’s delights like brown butter brookies.
- Chocolate-Covered Strawberries: These sweet bites add elegance while enhancing the chocolatey goodness.
- Nutty Granola Bars: For a crunchy texture contrast, serve granola bars on the side; they offer an interesting flavor profile alongside sweet desserts.
Common Mistakes to Avoid
When making Brown Butter Brookies, it’s essential to avoid common pitfalls that could affect your final product. Here are some mistakes to watch out for:
- Skipping the Browning Process: Not browning the butter can lead to a less rich flavor. Take the time to brown it for that nutty taste.
- Incorrect Measurements: Measuring ingredients incorrectly can ruin the texture. Always use a kitchen scale or proper measuring cups for accuracy.
- Overmixing the Dough: Overmixing can result in tough brookies. Mix just until combined to keep them soft and chewy.
- Underbaking or Overbaking: Baking times vary by oven. Keep an eye on them towards the end of baking to ensure they’re perfectly done.
- Not Letting Them Cool: Cutting into brookies too soon can cause them to fall apart. Allow them to cool completely in the pan before slicing.
