Slutty Brownies Recipe

Few desserts conjure up as much intrigue—or indulgence—as slutty brownies. This crowd-pleaser layers chocolate chip cookie dough, crunchy Oreos, and fudgy brownies into a single, decadent bar. Easy to make and hard to resist, these brownies balance chewy, crisp, and gooey in every forkful. Here’s how you can master them at home, plus everything you need to know for the ultimate treat.

What Are Slutty Brownies?

Slutty brownies have a playful name, but their reputation is serious. They stack three beloved desserts into one tray: a base of chocolate chip cookie dough, followed by a layer of whole Oreo cookies, topped with rich brownie batter. Each bite delivers a blend of soft cookie, chocolate crunch, and thick, fudgy brownie.

Ingredients and Variations

You only need three main building blocks. You can use homemade recipes or shortcut with store-bought dough and boxed mixes—either works.

Base Recipe

1 pound chocolate chip cookie dough (pre-made or homemade)
1 package Oreo cookies (regular or Double Stuf)
1 batch brownie batter (from a boxed mix or homemade—enough for a 9×9-inch pan)

Customization Ideas

Mix and match. Swap out different flavors or mix-ins to suit your crowd. Here are a few examples:

Try peanut butter or sugar cookie dough for a twist
Substitute golden Oreos, mint, or seasonal flavors for a new layer
Add caramel bits or swirl in peanut butter for extra richness
Top with chocolate chips, chopped nuts, or candy pieces before baking

Essential Tools

Having the right tools keeps prep simple and clean.

9×9-inch metal or glass pan
Parchment paper
Mixing bowls
Rubber spatula
Measuring cups and spoons

Step-by-Step Instructions

Getting the layers just right ensures the perfect slutty brownie texture. Follow these steps for even, gooey bars.

1. Prep Your Pan

Line your 9×9-inch baking dish with parchment paper, letting a bit hang over the edges for easy lifting after baking.

2. Layer the Cookie Dough

Press the chocolate chip cookie dough in an even layer on the bottom of the pan. If the dough is stiff, let it sit out for 10–15 minutes to soften.

Tip: Wet your fingers slightly to keep dough from sticking as you press it down.

3. Add the Oreo Layer

Arrange Oreo cookies in a tight single layer on top of the cookie dough. You may need to break a few cookies to cover the edges.

For extra crunch, leave the cookies whole. For a more uniform layer, gently press them in.

4. Pour the Brownie Batter

Prepare brownie batter according to the recipe or box instructions. Then, pour the batter over the Oreos, using a spatula to spread it edge to edge.

Avoid overfilling—keep the brownie layer about 1–1.5 inches thick so the whole thing bakes through.

5. Bake

Bake at 350°F (175°C) for 30–40 minutes. Every oven varies, so begin checking at 30 minutes. The edges should look set and a toothpick inserted near the center should come out mostly clean, with a few moist crumbs.

If the top browns too quickly, loosely tent with foil for the final 10 minutes.

6. Cool and Slice

Let the brownies cool in the pan for at least 1 hour. For cleaner slices, chill in the fridge for 30 minutes before cutting. Use the parchment as a sling to lift the slab onto a cutting board, then slice into squares.

Troubleshooting and Tips

Getting every layer just right has its nuances. Try these tips for success:

For extra-gooey bars, underbake slightly and serve warm with ice cream.
To avoid a raw cookie base, let the dough reach room temperature before baking.
Brownie batter should cover the Oreos fully but not overflow the pan.
If layering homemade dough, weigh out 1 pound or measure 2 packed cups.

Adjusting for Pan Size

Loaf pans or 8×8 pans also work. Springs in bake time apply—slightly less for loaf pans, slightly more for glass pans.

Pan Size	Bake Time	Notes
9×9-inch	30–40 minutes	Preferred size
8×8-inch	35–45 minutes	Thicker bars
Loaf pan	35–40 minutes	Smaller batch

Variations and Flavor Boosts

Slutty brownies invite creativity. Some favorite ways to switch it up:

Layer in caramel candies for salted caramel brownies.
Swap Oreos for Nutter Butters and peanut butter chips for a nutty spin.
Drizzle with chocolate or top with sprinkles before baking for party flair.

Storage and Freezing

Homemade slutty brownies keep well, making them ideal for making ahead.

Storing

Room temperature: Store sliced bars in an airtight container for up to 4 days.
Refrigerate: Lasts up to 1 week. The texture will be denser and chewier when cold.

Freezing

Place cooled, unsliced brownies in a freezer bag with parchment between layers. Or, wrap individual squares in plastic and foil. Freeze up to 3 months. Thaw at room temp or microwave briefly for that decadent, just-baked taste.

Frequently Asked Questions

Can I use different cookie dough?

Absolutely. Any cookie dough can form the base, from classic chocolate chip to oatmeal or even chocolate peanut butter.

Can I make slutty brownies gluten free?

Yes, use gluten free cookie dough, gluten free Oreos (or similar), and gluten free brownie mix. Texture may vary, so check doneness carefully.

Can I double the recipe?

Double everything and bake in a 9×13-inch pan. Increase baking time by 10–15 minutes, watching closely to avoid overbaking.

Serving Ideas

Serve plain, dusted with powdered sugar, or warm from the oven with a scoop of vanilla ice cream. Fresh berries add a nice contrast. For potlucks, wrap slices in parchment for grab-and-go servings.

Slutty brownies are pure fun—a triple-decker bar that brings joy to bakers and eaters alike. With a few pantry staples, they transform into a memorable dessert that works for parties, holidays, or just a sweet pick-me-up. Try new flavors, experiment with layers, and enjoy the playful spirit that slutty brownies bring to your kitchen.
