Instructions
Step 1: Prep the Oven and Pan
There’s something downright magical about a dessert that breaks all the rules—and this slutty brownie recipe does exactly that.
Step 2: Make the Cookie Dough
In a medium bowl, combine the melted butter with both sugars. Add the egg and vanilla extract, then stir until smooth. Fold in the flour, baking soda, and salt until a soft dough forms. Finish by gently mixing in the chocolate chips and pressing the dough evenly into your prepared pan.
Step 3: Layer the Oreos
Place the Oreo cookies on top of the cookie dough, pressing them in lightly. If needed, break a few cookies to cover the edges fully.
Step 4: Make the Brownie Batter
In a separate bowl, melt the butter and blend in both sugars until combined. Beat in the eggs and vanilla, ensuring the mixture is smooth. Gradually add the cocoa powder, flour, salt, and baking powder. Stir until just incorporated, then pour the batter evenly over the Oreo layer.
Step 5: Bake
Transfer the pan to your oven and bake for 30–35 minutes. You’ll know they’re done when a toothpick inserted into the center comes out with a few moist crumbs. Let the brownies cool completely in the pan before slicing.
Tips & Variations
- Add a peanut butter twist: Swirl 1/4 cup of peanut butter into the brownie batter for a richer flavor.
- Experiment with cookies: Golden Oreos, mint Oreos, or peanut butter-filled cookies all work beautifully.
- Make them gluten-free: Use a 1:1 gluten-free flour blend and gluten-free cookies for a safe alternative.

Serving Suggestions
These brownies are amazing served warm with a scoop of vanilla ice cream. Alternatively, you can chill them and pair with a hot espresso for a cozy treat. Either way, they’re a guaranteed hit.
How to Store Slutty Brownies
- At room temperature: Keep them in an airtight container for up to 4 days.
