Ingredients
Scale
- 1 cup unsalted butter, melted and divided
- 1/2 cup light brown sugar, packed
- 1 1/2 cups granulated sugar, divided
- 3 large eggs, divided
- 2 teaspoons vanilla extract, divided
- 1 1/4 cups all-purpose flour, divided
- 1/2 teaspoon baking soda
- 3/4 teaspoon salt, divided
- 3/4 cup semi-sweet chocolate chips
- 16 whole chocolate sandwich cookies
- 1/2 cup unsweetened cocoa powder
- 3/4 cup milk chocolate chips
Instructions
- Preheat the oven to 350°F. Line an 8×8-inch baking pan with parchment paper, leaving overhang on two sides.
- In a medium bowl, stir together 1/2 cup melted butter, light brown sugar, 1/4 cup granulated sugar, 1 egg, and 1 teaspoon vanilla extract.
- Add 3/4 cup all-purpose flour, baking soda, 1/4 teaspoon salt, and the semi-sweet chocolate chips. Mix until a soft cookie dough forms.
- Press the cookie dough evenly into the bottom of the prepared pan.
- Arrange the 16 chocolate sandwich cookies in a single layer over the cookie dough.
- In a separate bowl, whisk together the remaining 1/2 cup melted butter, remaining 1 1/4 cups granulated sugar, 2 eggs, and remaining 1 teaspoon vanilla extract.
- Whisk in the cocoa powder, remaining 1/2 cup all-purpose flour, remaining 1/2 teaspoon salt, and the milk chocolate chips until smooth.
- Spoon the brownie batter over the sandwich cookies and spread gently into an even layer.
- Bake for 35 to 40 minutes, until the top is set and a toothpick inserted near the edge comes out with moist crumbs.
- Cool completely in the pan on a rack. For cleaner slices, chill for 30 minutes after cooling, then lift out and cut into 16 bars.
Notes
- Do not overbake if you want a fudgy brownie layer.
- Let the bars cool completely before slicing for neat layers.
- Store in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week.
- Freeze individual bars for up to 2 months and reheat for 10 to 12 seconds in the microwave.
