How To Make Slutty Brownies
- Prepare The Cookie Dough:
- Cream butter and sugars until light and fluffy about 3 minutes on medium speed. Add egg and vanilla while scraping down sides to ensure even mixing. Incorporate dry ingredients on low speed just until combined avoid overmixing which toughens cookies. Fold in chocolate chips gently by hand for even distribution. The dough should be soft but not sticky.
- Create The Brownie Batter:
- Melt butter completely in a medium saucepan over medium heat until just melted. Add cocoa powder and sugar immediately after removing from heat to dissolve properly. Whisk vigorously until smooth and slightly cooled. Add salt and vanilla before incorporating eggs one at a time whisking constantly to prevent scrambling. Add flour and mix until just combined the batter should look glossy and pull away from sides slightly.
- Assemble The Layers:
- Line a 9x9 baking pan with foil or parchment leaving overhang for easy removal. Press cookie dough evenly into bottom creating a solid foundation about ½ inch thick. Arrange Oreos in a single layer covering the entire cookie base no overlapping needed. Pour brownie batter over Oreos spreading to corners ensuring complete coverage about ¾ inch thick.
- Bake To Perfection:
- Bake at 350°F for 35-40 minutes until a knife inserted in center comes out mostly clean with a few moist crumbs. The top should be set and slightly crackled. Allow to cool in pan for at least 2 hours before slicing this crucial step allows layers to set properly. Cut into 16 squares using a sharp knife wiped clean between cuts.

My absolute favorite part of these brownies is the magical middle where the cookie dough and brownie batter meet around the Oreo. Something extraordinary happens there – the cookie stays chewy, the Oreo softens just enough, and the brownie remains fudgy. It reminds me of Sunday afternoons baking with my grandmother, who always said the best recipes were the ones that combined multiple desserts.
Storage Instructions
These brownies maintain their incredible texture for up to 5 days when stored properly. Place them in an airtight container at room temperature, separating layers with parchment paper to prevent sticking. For longer storage, wrap individual squares in plastic wrap, then aluminum foil, and freeze for up to 3 months. Thaw at room temperature for about an hour before serving. The texture remains nearly perfect even after freezing, though the Oreos might be slightly less crunchy.

Variation Ideas
The beauty of Slutty Brownies lies in their adaptability. Try red velvet Oreos with white chocolate chips in the cookie layer for a Valentine's Day version. For mint lovers, use Mint Oreos and add a teaspoon of mint extract to the brownie batter. During fall, incorporate pumpkin spice Oreos and add cinnamon to the cookie dough. For extra decadence, drizzle caramel between the cookie and Oreo layers. The possibilities are endless, making these brownies perfect for customizing to any season or celebration.
Serving Suggestions
These indulgent bars deserve special presentation. Serve slightly warm with a scoop of vanilla ice cream for an over-the-top dessert experience. For coffee shops style service, dust with powdered sugar and place on small plates with a drizzle of chocolate sauce. At birthday parties, top with a candle and serve alongside milk. For dessert platters, cut into smaller bite-sized pieces and arrange with other cookies and brownies for variety. The contrast of textures and flavors pairs beautifully with coffee, milk, or a dessert wine.
