Slutty Brownies are the ultimate dessert experience. Created with layers of gooey brownie, cookie dough, and a hidden treasure of Oreo cookies, they’re a treat that combines the best of everything into one irresistible package. These indulgent bars became famous thanks to The Londoner and have since captured the hearts of dessert lovers everywhere. As a private chef, I’ve made them for countless clients, and they always steal the show. As Sofia Simpson humorously mentioned on The Tonight Show with Jay Leno, they’re called “slutty” because there’s just so much going on in them, and honestly, that’s what makes them so brilliant!
Substitutions and Variations
While the original recipe for Slutty Brownies uses boxed brownie mix, I prefer to make my brownies from scratch. It’s a simple swap that adds an extra layer of flavor and richness. But if you’re short on time or just looking for convenience, boxed brownies can certainly be used to speed up the process.
For a faster approach, you can also use pre-made cookie dough, like Toll House, instead of making your own. This saves even more time and still delivers delicious results.
During special seasons, I love to change up the Oreos to fit the occasion. For instance, orange Oreos are perfect for Halloween, while red and green Oreos add a festive touch during Christmas. I’ve even experimented with variations such as Slutty Blondie Brownies and S’mores Slutty Brownies to add even more fun twists!
Ingredients
For the Brownie Layer:
- 10 tablespoons unsalted butter
- 1 ¼ cups granulated sugar
- ¾ cup unsweetened cocoa powder
- ½ teaspoon kosher salt
- 2 teaspoons pure vanilla extract
- 2 large eggs
- ½ cup all-purpose flour
For the Oreo Layer:
- 1 package Oreos (regular or double-stuffed)
For the Cookie Dough Layer:
- ½ cup room-temperature unsalted butter
- ¼ cup light brown sugar
- ¾ cup granulated white sugar
- 1 egg
- 1 ¼ teaspoons pure vanilla extract
- 1 ¼ cups flour
- ½ teaspoon salt
- ½ teaspoon baking soda
- ½ teaspoon baking powder
- 1 cup semi-sweet chocolate chips
How to Make Slutty Brownies
Step 1: In a medium saucepan, melt the butter over medium-high heat. Stir in the granulated sugar and cocoa powder until combined. Remove from heat, and mix in the salt, vanilla, and eggs. Whisk until smooth, then set the mixture aside.
Step 2: Stir in the flour until the batter is fully combined. Set aside and let it cool slightly.
Step 3: For the cookie dough layer, use a mixer to blend the butter and both sugars until smooth and creamy. Add the egg and vanilla extract, mixing well. Be sure to scrape the sides of the bowl to ensure everything is well-incorporated.
Step 4: Mix the dry ingredients—flour, salt, baking soda, and baking powder—into the wet ingredients on a low speed until combined. Once blended, gently fold in the chocolate chips and set the dough aside.
Step 5: Press the cookie dough evenly into the bottom of a greased 9×9-inch baking pan. Make sure the layer is smooth and covers the entire base.
Step 6: Layer the Oreos over the cookie dough in a single, even layer. Arrange them snugly without overlapping.
Step 7: Pour the prepared brownie batter over the Oreo layer, spreading it evenly to cover the cookies.
Step 8: Bake for 35-40 minutes, or until a knife inserted in the center comes out clean (with just a few fudgy crumbs). Allow the brownies to cool for at least two hours before slicing. If the knife comes out with batter, continue baking for an additional 5 minutes. Let them cool fully before slicing to ensure you get clean, neat pieces.
Tips and Tricks
The key to perfect Slutty Brownies lies in the pan you use. I recommend a 9×9 square, non-stick pan. A glass pan or a different size may not yield the same texture or results. The non-stick material ensures that the brownies come out easily.
Once the brownies are out of the oven, let them cool for at least one hour before cutting into them. If you want to serve them in perfect squares, be patient and allow the layers to firm up as they cool.
Feel free to experiment with different kinds of Oreos. Double-stuffed, birthday cake, red velvet, or even peanut butter Oreos can all provide fun variations to the flavor of your Slutty Brownies.
If you opt for a boxed brownie mix, you may not need to use the entire amount of batter, as boxed mixes tend to produce more than the homemade version. Just make sure you have enough to cover the Oreo layer and create a fudgy texture.
Frequently Asked Questions
1. Can I use a different pan size for slutty brownies?
While a 9×9-inch square pan gives you the ideal thickness and texture, you can use other sizes if needed. Keep in mind that a larger pan will result in thinner layers and may require a shorter baking time. A smaller pan will produce thicker layers, which may need a few extra minutes in the oven.
2. What can I substitute for Oreos?
If Oreos aren’t your thing, you can substitute with other cookies like chocolate chip cookies, peanut butter cookies, or even digestive biscuits. These alternatives will slightly change the flavor but still maintain the concept of a cookie layer.
3. How should I store slutty brownies?
Store cooled and sliced Slutty Brownies in an airtight container at room temperature for up to three days. For longer storage, they can be refrigerated for up to a week. Just make sure to seal them tightly to preserve freshness.
4. Can I freeze slutty brownies?
Absolutely! Once the brownies are completely cooled, wrap each piece individually in plastic wrap and place them in a freezer-safe airtight container or zip-top bag. This prevents freezer burn and maintains the texture and taste. To enjoy, thaw at room temperature or warm them in the microwave for a gooey, fresh-baked experience.
5. Can I make slutty brownies gluten-free?
Yes! To make these brownies gluten-free, swap the all-purpose flour in both the cookie dough and brownie layers for a 1:1 gluten-free flour blend. Be sure to use gluten-free Oreos (many brands offer certified gluten-free versions) and double-check that all your other ingredients are also gluten-free.
6. Is it possible to make slutty brownies vegan?
Making these brownies vegan is definitely doable! Swap the butter for plant-based butter and replace the eggs with flax eggs or another vegan egg substitute. You can also use a vegan-friendly version of Oreos, as many are already dairy-free.
Final Thoughts
There you have it—a rich, gooey, indulgent dessert that’s sure to impress anyone lucky enough to try it. Slutty Brownies are perfect for any occasion, from casual gatherings to festive celebrations.
