People share these everywhere online, and it makes sense because the mix of textures feels bold. This recipe takes about 55 minutes, makes 16 squares, and lands at 592 calories each.

What Are Slutty Brownies?
Slutty Brownies stack three sweet layers that melt together as they bake. You start with chewy chocolate chip cookie dough. Then you add a full layer of chocolate sandwich cookies. Finally you pour glossy brownie batter on top.
Each bite feels soft, creamy, and fudgy all at once. People love them because they work for cravings, parties, and late night baking. Also, you can change flavors with different cookies or chocolate.
Ingredients You’ll Need
Cookie Dough Layer
You will need:
- 1 cup unsalted butter, softened (226g)
- ¾ cup brown sugar (150g)
- ½ cup granulated sugar (100g)
- 1 egg
- 2 tsp vanilla extract (10mL)
- 2 cups all purpose flour (240g)
- 1¼ tsp kosher salt
- ½ tsp baking powder
- ¼ tsp baking soda
- 1 cup semi sweet chocolate chips
- ½ cup quick oats
Soft butter helps the dough mix smoothly, and brown sugar adds deeper flavor.
Oreo Layer
Place 18 chocolate sandwich cookies between the dough and brownie layers. You can also try Double Stuf or flavored cookies.
Brownie Layer
Use:
- ¾ cup unsalted butter, melted
- ½ cup brown sugar (100g)
- ½ cup granulated sugar (100g)
- 2 tsp vanilla extract (10mL)
- 2/3 cup cocoa powder (65g)
- ½ cup all purpose flour (60g)
- 2 tsp espresso powder
- ½ tsp kosher salt
- ½ tsp baking powder
- 2 eggs
- ½ cup semi sweet chocolate chips
Espresso powder lifts the chocolate flavor and adds depth.
How to Make Slutty Brownies
Step 1: Prepare the Cookie Dough
Start by creaming the butter and sugars until fluffy. Add the egg and vanilla.
In another bowl, whisk flour, salt, baking powder, and baking soda.
Next, add the dry mix to the wet mix and stir until smooth. Fold in oats and chocolate chips.
Spread half the dough into a lined and greased 9×9 pan. Keep the rest chilled.
Step 2: Add the Oreo Layer
Set the 18 cookies on top of the dough. You can break pieces to fill empty spaces. The batter will settle around them later.
Step 3: Make the Brownie Batter
Preheat the oven to 350°F.
In one bowl, mix cocoa powder, flour, espresso powder, and baking powder.
In a second bowl, whisk melted butter, sugars, eggs, and vanilla.
Also, sift the dry mix into the wet mix and stir until no streaks remain. Fold in chocolate chips.
Step 4: Assemble and Bake
Pour the brownie batter over the cookies and spread it evenly.
Bake at 350°F for 35 to 40 minutes until the center looks set.
Let the pan cool for about 2 hours so the layers settle. Slice clean squares once cool.
Pro Tips for Perfect Slutty Brownies
Chill the cookie dough so it spreads slowly.
Also, beat the brownie batter well after adding eggs because it gives you that shiny, crackly top.
Let the brownies cool fully before slicing so you get smooth edges.
Save extra cookie dough in the freezer for future cookies baked at 350°F for 10 to 12 minutes.
Sprinkle a little flaky sea salt on top if you like sweet and salty balance.
Storage and Make Ahead Tips
Store your Slutty Brownies in an airtight container for up to 3 days.
You can also refrigerate them for a week.
Freeze baked squares for up to 3 months. Wrap each piece so it stays fresh.
Warm them slightly before serving so the chocolate softens again.
