Preparation Phase & Tools to Use

Before diving into the layers of indulgence, it’s good to have your kitchen essentials ready. Each tool here plays a big role in making sure these brownies bake up perfectly:

9×9 inch baking pan: The ideal size to ensure even baking and thick, satisfying layers.
Parchment paper: Makes lifting the brownies out for slicing mess-free.
Mixing bowls (2-3): One for cookie dough, one for brownie mix, and one more if you’re making anything from scratch.
Rubber spatula: Great for spreading layers evenly without disturbing the one beneath.
Electric mixer (optional): Speeds up the creaming process for the cookie dough base.
Measuring cups and spoons: Precision counts when it comes to the perfect bake.

Ingredients for the Slutty Brownies

Chocolate chip cookie dough: Forms the chewy base and brings that buttery vanilla flavor.
Double-stuffed Oreos: The signature middle layer that adds crunch and creaminess.
Brownie batter: Rich and fudgy, this tops everything with deep chocolate flavor.
Butter: Adds moisture and richness to both cookie and brownie layers.
Brown sugar: For that soft chew and slight caramel hint in the cookie base.
Granulated sugar: Balances sweetness and structure in both layers.
Eggs: Binds the batter and gives brownies that crackly top.
Vanilla extract: Adds a warm, aromatic finish.
All-purpose flour: The structural backbone of both layers.
Cocoa powder: Gives the brownies their deep chocolate flavor.
Salt: Enhances and balances all the sweet flavors.

How To Make the Slutty Brownies

Step 1: Prep Your Pan

Line a 9×9 inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease it to ensure nothing sticks.

Spread an even layer of chocolate chip cookie dough into the base of the pan. Press it down gently with a spatula to cover the bottom fully.

Step 3: Add the Oreos

Place a single layer of Oreos on top of the cookie dough. No need to press—just let them rest snugly over the cookie layer.

Step 4: Pour the Brownie Batter

Carefully pour your prepared brownie batter over the Oreos. Use a spatula to spread it evenly to all corners.

Step 5: Bake to Perfection

Bake at 350°F (175°C) for about 35–40 minutes. The top should be set and a toothpick should come out mostly clean, with a few moist crumbs attached.

Step 6: Cool & Slice

Let them cool in the pan completely before lifting them out. Slice into generous squares and enjoy every luscious bite.

How to Serve and Store Slutty Brownies

Serve them warm with a scoop of vanilla ice cream or let them cool and stack for an irresistible dessert tray. These brownies are thick and dense, so small squares go a long way—but don’t be surprised if guests come back for seconds.

To store, keep them in an airtight container at room temperature for up to 4 days. For longer freshness, refrigerate for up to a week or freeze in layers with parchment for up to 2 months. Just reheat in the microwave for 15-20 seconds for that fresh-out-the-oven experience.

Frequently Asked Questions

Can I use boxed mixes for this recipe?

Absolutely! A boxed brownie mix and pre-made cookie dough work great for a quick version.

What other cookies can I use instead of Oreos?

Try peanut butter cookies, chocolate chip sandwich cookies, or even mint-flavored ones for a twist.

Can I make them gluten-free?

Yes, simply substitute gluten-free flour blends and gluten-free cookie dough and brownies.

How do I know when the brownies are done?

The edges will be firm and the center set. A toothpick should come out with moist crumbs but not wet batter.

Do I need to chill before slicing?

It helps! Letting them cool completely (or even refrigerating) makes for cleaner cuts.
