The bars are neatly cut, showing distinct layers and clean edges.

Ingredients

3/4 cup unsalted butter (168 grams), softened
1/2 cup brown sugar (105 grams)
1/2 cup white sugar (100 grams)
1 large egg
1 large egg yolk (discard the white)
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour (188 grams)
1/4 teaspoon salt
2/3 cup chocolate chips (120 grams)
28 Oreo cookies
1/2 cup unsalted butter (112 grams), cubed
6 oz dark chocolate (170 grams), 50-70% or semi-sweet
1 cup granulated sugar (200 grams)
2 large eggs
1/2 cup all-purpose flour (63 grams)
1/4 cup cocoa powder (23 grams)
1/2 teaspoon salt

Instructions

Step 1: Preheat the oven to 350°F (180°C). Lightly grease a 9×13 inch (23×33 cm) pan, then line it with parchment paper leaving an overhang on the sides. Greasing first helps the paper stick better.
Step 2: For the chocolate chip cookie layer, beat together the softened butter, brown sugar, and white sugar in a large bowl until well combined. Add the egg, egg yolk, and vanilla extract, mixing thoroughly but do not add the second egg white.
Step 3: With the mixer on low speed, gradually beat in the flour and salt. Turn off the mixer and fold in the chocolate chips using a spatula or wooden spoon. Spread this mixture evenly into the prepared pan.
Step 4: Arrange the Oreo cookies on top of the cookie dough layer, pressing them down slightly to ensure they stick. Use about 7 rows of 4 cookies and add some halves to cover the surface completely.
Step 5: For the brownie batter, finely chop the dark chocolate. Place the chocolate and cubed butter into a heatproof bowl and microwave in 45-second intervals on medium power, stirring between sessions until smooth. Avoid microwaving on high to prevent burning.
Step 6: Let the chocolate mixture cool for about 5 minutes. Then whisk in the eggs and granulated sugar until combined.
Step 7: Sift together the flour, cocoa powder, and salt, then whisk them into the chocolate mixture until just combined. Spoon the brownie batter in dollops over the Oreo layer, then gently spread it evenly across the pan.
Step 8: Bake the assembled layers for 37-45 minutes, or until a toothpick inserted comes out with a few moist crumbs but not wet batter. Baking time depends on your oven and desired gooeyness.
Step 9: Let the brownies cool completely in the pan for at least 4 hours. Use the parchment paper overhang to lift them out before slicing on a cutting board.

Tips & Variations

Use high-quality chocolate with 50-70% cocoa for rich flavor and smooth texture.
If the flour or cocoa powder is lumpy, sift before adding to ensure a smooth batter.
For an extra fudgy brownie layer, slightly underbake and let them set while cooling.
Try different cookie varieties instead of Oreos for a unique twist.

Storage

Store leftover slutty brownies at room temperature in an airtight container for up to 4 days. They can also be refrigerated to extend freshness but bring to room temperature before serving. Reheat briefly in the microwave if you prefer warm brownies.

How to Serve

Two stacked dessert bars sit on a white plate over a white marbled texture background. Each bar has four visible layers: the bottom layer is a light brown cookie dough with chocolate chips, above that is a dark chocolate cookie sandwich layer with white cream in the center, followed by a thick dark brown fudgy brownie layer, and the top has a slightly cracked brownie crust. The top bar has a bite taken out, showing the soft texture of the brownie and cookie dough inside. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make this recipe gluten-free?

You can substitute all-purpose flour with a gluten-free baking flour blend in equal amounts. Ensure the Oreos you use are also gluten-free if necessary.

Can I prepare the layers ahead of time?

Yes, you can prepare the cookie dough and brownie batter separately ahead of time. Assemble and bake when ready. However, baking fresh yields the best texture.
