I love making these Slutty Brownies whenever I want a rich and over-the-top dessert that combines three irresistible layers in one bite. I start with a chewy chocolate chip cookie base, add a layer of crunchy Oreo cookies, and finish everything with a fudgy brownie topping. The result is a decadent dessert bar that is gooey, chocolatey, and impossible to resist.
Why You’ll Love This Recipe
I love this recipe because it brings together three classic desserts into one easy treat. The cookie layer stays soft and buttery, the Oreo center adds crunch, and the brownie topping turns rich and fudgy after baking. I also like how simple the recipe is to prepare since I can use pantry staples and layer everything together in one pan. These brownies are perfect for parties, movie nights, bake sales, or whenever I crave something extra indulgent.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
For the Cookie Layer
1 cup unsalted butter, softened
3/4 cup brown sugar
1/2 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
2 1/4 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 1/2 cups chocolate chips
For the Oreo Layer
24 Oreo cookies
For the Brownie Layer
1/2 cup unsalted butter, melted
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/3 cup unsweetened cocoa powder
1/2 cup all-purpose flour
1/4 teaspoon salt
1/4 teaspoon baking powder
Directions
I preheat the oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper.
I make the cookie layer by creaming the softened butter, brown sugar, and granulated sugar together until light and fluffy. Then I mix in the eggs and vanilla extract.
I stir in the flour, baking soda, and salt until combined before folding in the chocolate chips.
I press the cookie dough evenly into the prepared baking pan.
I place the Oreo cookies in a single layer over the cookie dough.
I prepare the brownie batter by whisking the melted butter and sugar together. Then I add the eggs and vanilla extract.
I stir in the cocoa powder, flour, salt, and baking powder until smooth.
I spread the brownie batter evenly over the Oreo layer.
I bake the bars for 35 to 40 minutes until the top is set and a toothpick inserted into the brownie layer comes out with a few moist crumbs.
I let the brownies cool completely before slicing them into squares.
Servings and Timing
Servings: 16 bars
Prep Time: 20 minutes
Cook Time: 35–40 minutes
Total Time: About 1 hour
Variations
I sometimes add peanut butter chips or white chocolate chips to the cookie layer for extra flavor. When I want a richer dessert, I drizzle melted chocolate or caramel sauce over the cooled brownies. I also enjoy using flavored Oreo cookies like mint or peanut butter for a fun twist.
Storage/Reheating
I store the brownies in an airtight container at room temperature for up to 4 days. If I want them to stay fresh longer, I refrigerate them for up to 1 week. I also freeze individual slices for up to 2 months and thaw them before serving. When I want a warm dessert, I microwave a brownie square for about 10 to 15 seconds.
FAQs
Can I use boxed brownie mix instead of homemade brownie batter?
I sometimes use boxed brownie mix when I want to save time, and it still turns out delicious.
How do I know when the brownies are done baking?
I check the center with a toothpick and look for a few moist crumbs instead of wet batter.
Can I make these brownies ahead of time?
I often make them a day ahead because the layers become even more flavorful after resting.
What type of chocolate chips work best?
I usually use semi-sweet chocolate chips, but milk chocolate or dark chocolate also work well.
Can I freeze Slutty Brownies?
I freeze them in airtight containers or freezer bags, and they thaw beautifully when I am ready to enjoy them.

I always enjoy making these Slutty Brownies because they deliver the perfect combination of chewy cookies, crunchy Oreos, and rich brownies in every bite. They are easy to prepare, fun to share, and guaranteed to satisfy any chocolate craving. Whether I serve them at gatherings or enjoy them at home, they never last long on the dessert table.
