- 1 tsp baking soda
- 1 tsp baking powder
- 1/2 tsp salt
- 1 and 1/2 cups chocolate chips
For the Brownie 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
Let’s Make It Together
Prep:
- Preheat your oven to 350℉ (175℃). Spray a 9×13 metal pan with nonstick spray and line it with parchment paper for easy removal and slicing later.
Make the Chocolate Chip Cookie Dough:
- Melt 14.5 tbsp of salted butter in a large mixing bowl. Whisk in the dark brown sugar and granulated sugar. Then, add the eggs and vanilla extract, whisking until smooth and combined, about 30-45 seconds.
- Stir in the dry ingredients: flour, baking soda, baking powder, and salt, then fold in the chocolate chips.
- Divide the dough into two equal halves (about 640 grams each). Press half of the dough into the prepared pan, then lift out that piece of parchment paper and replace it with a new piece. Set your layer of cookie dough aside and leave the rest in the bowl for later.
Brown the Butter:
- In a medium saucepan, add the cubed butter (for the brownie layer) over medium heat. Melt and stir occasionally. Once melted, turn the heat to medium-low and continue cooking, stirring frequently until the butter turns a deep golden shade and gives off a nutty, caramel aroma—this should take about 3-6 minutes.
Make the Brownie Batter:
- Stir in your semi-sweet chocolate into the browned butter until completely melted, then whisk in the vegetable oil and cocoa powder. Set aside to cool slightly.
- In a large mixing bowl, combine the eggs, egg yolk, and granulated sugar, whisking for about 1-2 minutes until the sugar is fully dissolved and smooth.
- Add in the powdered sugar, vanilla, and salt, whisking until smooth. Ensure your chocolate mixture is no longer piping hot, and whisk it into the bowl of eggs and sugar. Fold in the flour and optional espresso powder, then the chocolate chips.
Assemble:
- Spread slightly more than half the brownie batter in the bottom of your lined pan. Lay the sheet of cookie dough on top, removing the extra piece of parchment paper. Spread the remaining brownie batter on top.
- Form large, thick discs with the remaining cookie dough and set on top of the brownie batter. Press in extra chocolate chips to any bare spots on the cookie dough if desired.
Bake:
- Bake the assembled brookies for 38 to 44 minutes. You’ll know they’re done when the cookies are golden and the brownies have a shiny top. A toothpick inserted into the center of a brownie spot should have some moist crumbs but no wet batter. Avoid over baking!
Serve & Store:
- Allow the bars to cool in the pan on a wire rack for 1 – 2 hours before slicing. Sprinkle with flaky sea salt, if desired! Store leftover bars in an airtight container at room temperature for 3-4 days. I highly recommend warming leftover slices back up in the microwave for that fresh-baked flavor!
Delicious Variations to Try
- Nutty Delight: Add chopped nuts like walnuts or pecans for a deliciously crunchy contrast.
- Fruity Twist: Fold in dried cherries or raspberries to give the brookies a fruity zing.
- Peppermint Surprise: During the holiday season, toss in a handful of crushed candy canes with the chocolate chips for a festive flair.
- Peanut Butter Lovers: Drizzle peanut butter over the brownie layer before adding the cookie dough, mixing both flavors beautifully.
Chef Emma’s Helpful Tips
- Make Ahead: You can prepare the dough and batter a day in advance. Just bake them when you’re ready!
- Ingredient Swaps: If you don’t have brownie mix, you can substitute the semi-sweet chocolate with cocoa powder for a lighter chocolate flavor.
- Slicing Trick: For perfectly neat slices, use a sharp knife dipped in warm water to cut through the bars, giving you those bakery-quality edges.
- Storage Suggestion: Keep these delights well-covered at room temperature, but if you want them to last a little longer, go for refrigeration!
