Table of contents
Ingredients Needed

(full list of ingredients can be found in the recipe card)
- Semi-Sweet Chocolate Chips creates those melty pockets of chocolate throughout the brownie and cookie layers without making the dessert overly sweet. For the brownies batter, be sure to use high quality Semi-Sweet Chocolate. It adds a deep, rich chocolate flavor and gives the brownie layer a smooth, fudgy, almost ganache-like texture.
- Dutch Process Cocoa Powder adds a smooth yet bold chocolate flavor with less acidity than natural cocoa for a richer taste.
- Salted Butter brings moisture and flavor while the salt balances out sweetness and enhances the chocolate.
- Cornstarch softens the structure of the baked bars, helping keep the brownies thick, tender, and ultra-fudgy.
- Espresso Powder enhances the chocolate flavor without making the recipe taste like coffee, it simply makes it bolder and deeper.
- Brown Sugar adds moisture and chewiness thanks to its molasses content, giving the brookies a richer, more caramel-like flavor.
- Granulated Sugar contributes sweetness and structure while helping create crisp edges and that glossy crackly brownie top.
Substitutions
- For a less sweet flavor, use dark chocolate instead of semi-sweet. Alternatively, for a super sweet brookie, use milk chocolate!
- Add mix-ins! Feel free to throw in some chopped nuts or additional chopped chocolate. This is one of those dessert mashups where no you can’t go wrong!
- For gluten free option, use your favorite 1 to 1 gluten free flour!
- If you love brown butter chocolate chip cookies, brown the butter in a pan before assembling the dough.
How To Make The Best Brookies Recipe
Prep: Preheat the oven to 325 degrees F. Line a 8×8 baking pan with parchment paper, leaving about 2 inches overhang (so that you can easily remove the brookies once they’re done).
Make The Cookie Dough and Brownie Batter

Step 1: Make the chocolate chip cookie dough. Melt butter in the microwave in a large mixing bowl, then add in the brown sugar and sugar. Whisk together then add in the egg and vanilla extract. Use a rubber spatula to fold in the all purpose flour, baking powder, baking soda, and kosher salt. Mix until a dough begins to form, then add in the chocolate chips. Mix to combine and set aside.

Step 2: Now make the brownie batter. Add semi-sweet chocolate and butter to a large microwave safe bowl. Microwave for about 40 seconds, until the butter is melted, then whisk together (it’s ok if everything is not fully melted). Microwave again in 15 second increments, whisking in between, until the chocolate is fully melted. Add in oil, cocoa powder, and espresso powder and whisk to combine, then set aside.

Step 3: In a separate bowl, add the eggs, egg yolk, brown sugar, and sugar. Use an electric mixer and beat together for 3 minutes on medium speed until frothy and sugar is dissolved (you’ll know the sugar is dissolved when you rub a little bit of the mixture between your fingers and it’s no longer gritty. Pour in the chocolate mixture and continue to mix until combined, about 30 seconds.

Step 4: Scrape down the side of the bowl to ensure everything is fully combined, then add in the all purpose flour and kosher salt. Use a rubber spatula to combine, then add in the chocolate chips.
Assemble and Bake!

Step 5: Add half of the brownie batter to the prepared pan to form the brownie layer. Add in half of the chocolate chip cookie dough and spread into an even layer. Add the remaining brownie batter on top, ensuring all of the cookie layer is covered.

Step 6: Roll the remaining cookie dough into balls (it doesn’t matter the size, I did about 9 balls) and place them on top of the brownie batter. Bake for 40-45 minutes, until the edges are set and the center has the slightest jiggle, like jello.

Let them rest! Allow the brookies to cool to room temperature for about 30 minutes, then place into the refrigerator to set for about 4 hours. (for an extra gooey brownie, you can eat them immediately. for super fudgy brownies, refrigerate to set)
No Fail Tips For Homemade Brookies
- Underbake slightly = elite results. Pull them when the center still has a slight jiggle. They’ll keep cooking as they cool and set into that gooey-but-sliceable magic.
- Line your pan with parchment and leave overhang. This is non-negotiable! It makes it easier to pull the brownies out of the pan.
- Let the brookies COOL completely before cutting. Hot brookies are like molten lava. Chilled brookies slice like a dream. If you’re impatient (hi, me), chill to room temperature and then cut (just know they’ll be suuuper gooey)
- Avoid using glass pans. Glass takes a while to heat up and then holds onto the heat, leading to overbaked baked goods. Opt for a metal pan when baking for best results!
Recipe FAQs
For best results, no. You can but the baking time and final results will be different.
The edges should look fully baked and slightly puffed, while the center should have a gentle jiggle like Jell-O when gently shaking the pan.
Store brookies in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days to keep them extra chewy and rich.
It doesn’t make them taste like coffee, it simply intensifies the chocolate flavor and gives your brownie layer that deep bakery style richness.
If you want set, fudgy brownies/brookies, yes. Refrigerating helps the brownies firm up and makes slicing dreamy and neat. If you slice fresh out of the oven, they’ll likely be very VERY gooey.

The taste was great, but my Brookies were 4 inches tall. I looks like the pan should have been larger than 8×8. Also, because of the thickness the center wasn’t cooking and had to leave in the oven an additional 20 minutes, so the outside was a little over-done.
Hi Betsy! You can absolutely use a large pan, such as a 9×9 if you’d like shorter thinner brookies, just keep in mind you’ll need to reduce cooking time. When checking for doneness, the center should be just a smidge wobbly, like jello, it should not be fully set or else you can end up overcooking them and you won’t get that fudgy center. I’m glad that you liked the taste!
