Ingredients

Scale

Brownie Layer

1 box brownie mix (Ghirardelli, Betty Crocker, or Duncan Hines)
Ingredients required by the mix (typically eggs, oil, and water)

Cookie Layer

12 tbsp butter, melted and slightly cooled
1 cup brown sugar
½ cup granulated sugar
1 large egg + 1 egg yolk
2 tsp vanilla extract
2 cups + 2 tbsp all-purpose flour
½ tsp baking soda
½ tsp salt
1½ cups semi-sweet chocolate chips

Instructions

Preheat the oven to 325°F (163°C). Line a 9×13-inch baking dish with parchment paper or grease it with non-stick spray.
Prepare the brownie layer by following the instructions on the brownie mix box. Pour the batter into the prepared baking dish and spread it evenly.
Make the cookie dough: In a large bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth.
Add the egg, egg yolk, and vanilla extract, mixing until well combined.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this to the wet ingredients, stirring until just combined.
Fold in the chocolate chips and mix until evenly distributed.
Drop spoonfuls of cookie dough over the brownie batter. Use a spatula to gently spread it out without fully mixing the layers.
Bake for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out with a few moist crumbs.
Allow the brookies to cool for at least 1 hour before slicing into squares.

Notes

For a fudgier texture, slightly underbake the brookies and let them set as they cool.
If using a larger brownie mix (for 9×13 pans), adjust the baking time as needed.
Store brookies in an airtight container at room temperature for up to 4 days, or refrigerate for up to a week.
To freeze, wrap individually and store in a freezer-safe container for up to 3 months.
