Kitchen Equipment
To prepare these brownies, you’ll need:
- Mixing bowls
- Electric mixer or whisk
- Spatula
- 9×13 inch baking pan
- Parchment paper (optional for easy removal)
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C).
Line a 9×13 inch baking pan with parchment paper or lightly grease it with butter or cooking spray.
2. Prepare the Cookie Dough
In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until smooth and fluffy.
Add the eggs and vanilla extract, mixing until well combined.
In a separate bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture and stir until a dough forms.
Fold in the chocolate chips.
3. Create the Cookie Base
Press the cookie dough evenly into the bottom of the prepared baking pan.
Make sure the dough forms a uniform layer that covers the entire base.
4. Add the Oreo Layer
Place Oreo cookies in a single layer on top of the cookie dough.
Arrange them evenly so that each brownie square will contain at least one Oreo.
You can place them whole or slightly press them into the dough.
5. Prepare the Brownie Batter
Prepare the brownie mix according to the instructions on the package.
Once the batter is ready, gently pour it over the Oreo layer.
Use a spatula to spread the batter evenly so it completely covers the cookies.
6. Bake the Brownies
Place the pan in the oven and bake for 35–45 minutes.
The brownies are done when the top is set and a toothpick inserted into the brownie layer comes out with a few moist crumbs.
Avoid overbaking to keep the brownies soft and fudgy.
7. Cool Before Cutting
Allow the brownies to cool in the pan for at least 30–40 minutes.
Once cooled, lift them out using the parchment paper (if used) and cut into squares.
Cooling helps the layers set properly and makes slicing easier.
Tips for Perfect Slutty Brownies
Do not overbake
Slightly underbaked brownies stay fudgy and delicious.
Use parchment paper
This makes removing the brownies from the pan much easier.
Let them cool completely
Cutting too soon can cause the layers to fall apart.
Use quality chocolate chips
Better chocolate enhances the overall flavor.
Fun Variations
These brownies are very flexible, and you can customize them in many ways.
Peanut Butter Version
Add peanut butter chips to the cookie dough or swirl peanut butter into the brownie layer.
Mint Chocolate Brownies
Use mint-flavored sandwich cookies instead of classic Oreos.
Double Chocolate
Add extra chocolate chips to the brownie batter.
Caramel Delight
Drizzle caramel sauce between the Oreo and brownie layers.
Serving Ideas
Slutty brownies are delicious on their own, but they can also be served in creative ways.
Try serving them with:
- Vanilla ice cream
- Chocolate sauce drizzle
- Whipped cream
- Fresh berries
Warm brownies paired with cold ice cream create an especially indulgent dessert.
Storage Tips
Room temperature
Store in an airtight container for up to 3 days.
Refrigerator
Keeps well for up to one week.
Freezer
Wrap individual pieces and freeze for up to 2 months.
To enjoy frozen brownies, simply thaw at room temperature or warm briefly in the microwave.
