What Are Slutty Brownies?

If you’ve never heard of slutty brownies before, let’s clear things up. Despite the cheeky name, there’s nothing inappropriate here—just decadence layered on top of more decadence.

A classic slutty brownie is made with three main components:

• A base layer of chocolate chip cookie dough
• A layer of Oreos
• A top layer of brownie batter

Baked together, these three elements fuse into a dessert bar that’s chewy, crunchy, soft, gooey, and chocolatey all at once. The name started as an internet joke, but the dessert quickly went viral—and for good reason.

Why You’ll Love This Slutty Brownie Recipe

There are a lot of slutty brownie recipes out there, but here’s why this one is special:

• Made from scratch: No boxed mixes here. Both the cookie dough and brownies are homemade with rich, bakery-quality flavor.
• Customizable: Use your favorite Oreos, add a pinch of sea salt, or swap in dark chocolate—the possibilities are endless.
• Crowd favorite: These bars are thick, dramatic, and practically beg to be shared (or not—we won’t judge).

Want something even more nostalgic? Try pairing these with my no-churn vanilla ice cream or a drizzle of hot fudge sauce. You’re welcome.

What Makes These Slutty Brownies Different?

These aren’t just any slutty brownies. They’re made using my go-to brownie recipe and my signature chocolate chip cookie dough—the same ones that have earned rave reviews from thousands of readers. If you’ve baked either of those recipes before, you already know you’re in for a treat.

• The brownie layer is rich, fudgy, and full of deep chocolate flavor—thanks to a blend of melted chocolate, cocoa powder, and a touch of espresso powder to intensify the taste.
• The cookie dough base is chewy, buttery, and loaded with chocolate chips for the perfect contrast to the soft brownie top.

These two recipes were basically made for each other—and when you sandwich some Oreos in between? Game over.

For the Chocolate Chip Cookie Dough:

• Salted butter
• Light brown and granulated sugar

• All-purpose flour
• Baking soda + salt
• Semi-sweet and milk chocolate chips

For the Oreo Layer:

• Double Stuf Oreos (about 20–24 cookies)

Step-by-Step Instructions for Slutty Brownies

1. Make the Cookie Dough

Cream the butter and sugars, then beat in the egg and vanilla. Mix in the dry ingredients until just combined, then fold in the chocolate chips. Press the dough evenly into a lined 9×13-inch pan.

2. Layer the Oreos

Place whole Double Stuf Oreos in a single layer on top of the cookie dough. I like to break a few in half to fill in the gaps so every bite gets some Oreo goodness.

3. Make the Brownie Batter

Melt the butter and chocolate together, stir in the espresso powder, and let it cool slightly. In a separate bowl, beat the eggs and sugar until pale and thick—this step is key to getting that signature crackly top.

Mix in the vanilla and melted chocolate, then gently fold in the dry ingredients and chocolate chips until just combined.

4. Assemble the Slutty Brownies and Bake

Pour the brownie batter evenly over the Oreos, smoothing out the top. Bake at 350°F (175°C) for 35–45 minutes, or until a toothpick inserted into the center comes out with moist crumbs (but no wet batter).

Cool completely before slicing—this is important! The layers need time to set for clean, beautiful cuts.

Tips for Perfect Slutty Brownies

• Let them cool: It’s tempting to dig in right away, but slutty brownies slice best when fully cooled. Pop them in the fridge for 30 minutes to speed things up.
• Customize the Oreos: Try flavored Oreos like peanut butter, birthday cake, or even the seasonal ones. It’s a fun way to switch things up.
• Storage: Store at room temperature in an airtight container for up to 4 days. They also freeze well for up to 2 months.

Fun Brownie Variations to Try

Want to mix things up? Here are some fun ideas:

• Salted caramel slutty brownies: Drizzle caramel sauce over the Oreo layer before adding brownie batter.
• Peanut butter version: Use Nutter Butters or peanut butter cups instead of Oreos.
• S’mores style: Swap Oreos for graham crackers and add mini marshmallows between the layers.

I also love topping all of my brownies with some flaky sea salt. There’s just something about chocolate and salt; it’s perfection. Try out my Homemade Vanilla Bean Salt Recipe.

Slutty Brownie Recipe FAQs

Can I use boxed brownie mix for Slutty Brownies?

Yes! While I always recommend homemade for the richest flavor, a good-quality boxed brownie mix will still work. If you’re using a mix, prepare it according to package instructions and pour it over the Oreo layer just like you would with the homemade version.

Can I use store-bought cookie dough?

Absolutely. Store-bought cookie dough is a great time-saver when you need a shortcut. Use about 16–18 ounces of refrigerated chocolate chip cookie dough, and press it evenly into the bottom of your 9×13-inch pan. Just be sure it’s the kind that comes in a log or tub (not pre-portioned balls), so you can spread it smoothly.

Do I have to use Double Stuf Oreos?

Not at all! Regular Oreos work perfectly, but Double Stuf Oreos add a thicker, creamier middle layer that makes the final dessert extra gooey. You can also try fun variations like peanut butter, birthday cake, or mint Oreos.

Can I make these in an 8×8 pan?

Yes, you can halve the recipe for an 8×8-inch pan. Bake at the same temperature (350°F), and start checking for doneness around 35–40 minutes. The smaller batch will yield thicker layers.

How do I know when they’re done baking?

You’ll know they’re ready when a toothpick inserted into the brownie layer comes out with moist crumbs but no wet batter. It’s better to slightly underbake than overbake—slutty brownies are meant to be gooey!

How should I store slutty brownies?

Once cooled, store your brownies in an airtight container at room temperature for up to 4 days, or in the fridge for up to a week. You can also freeze individual squares for up to 2 months. Just thaw at room temp before enjoying.
