Ingredient Notes

All-Purpose Flour: Forms the structure for both the cookie dough and brownie layers.
Unsalted Butter: Essential for richness and flavor. Substitute with salted butter, but reduce the added salt slightly.
Granulated Sugar & Brown Sugar: Brown sugar adds chewiness and depth; granulated gives crispness.
Eggs: Bind the ingredients and keep the texture moist.
Vanilla Extract: Enhances the overall flavor; don’t skip it!
Chocolate Chips: Semi-sweet works best for balance, but you can also use milk or dark chocolate.
Oreo Cookies: The signature middle layer. Swap with any sandwich cookie or flavored Oreos for variety.
Cocoa Powder: For the brownie batter. Use unsweetened, high-quality cocoa for the richest flavor.
Baking Powder & Baking Soda: Help give the cookie and brownie layers the right rise and texture.
Salt: Just a pinch sharpens the chocolatey goodness.

Special Equipment: An 8×8-inch square baking pan lined with parchment paper for easy removal.

How To Make Slutty Brownies – Homemade, Fudgy, Delicious

Preheat your oven to 350°F (175°C) and line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy lifting.
Prepare the cookie dough layer.
In a bowl, cream together 1/2 cup softened butter, 1/2 cup brown sugar, and 1/4 cup granulated sugar until fluffy. Add 1 egg and 1 teaspoon vanilla extract. Mix in 1 cup flour, 1/2 teaspoon baking soda, and a pinch of salt. Stir in 1/2 cup chocolate chips.
Press the cookie dough into the bottom of the prepared pan, spreading it evenly. Make sure the layer reaches all corners.
Add a layer of Oreo cookies.
Lay whole Oreos across the cookie dough in a single, even layer. Don’t crush — leave them whole for that signature texture.
Prepare the brownie batter.
In another bowl, whisk together 1/2 cup melted butter, 1 cup sugar, 2 large eggs, and 1 teaspoon vanilla extract. Sift in 1/3 cup cocoa powder, 1/2 cup flour, 1/4 teaspoon baking powder, and a pinch of salt. Stir until smooth.
Pour the brownie batter over the Oreo layer, spreading evenly.
Bake for 35-40 minutes, until the top is set and a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).
Cool completely in the pan before slicing. This helps the layers hold together.

Tip: For clean slices, chill in the fridge for 1 hour before cutting.

Storage Options

Room Temperature: Store in an airtight container for up to 3 days.
Refrigeration: Keeps fresh for up to 1 week, just let them sit at room temp for 15 minutes before serving.
Freezing: Freeze in a single layer, then transfer to a zip-top bag for up to 3 months.
Reheating: Warm individual pieces in the microwave for 10-15 seconds for that gooey, fresh-baked feel.

Variations and Substitutions

Peanut Butter Twist: Add peanut butter chips to the cookie dough and swirl some peanut butter into the brownie batter.
Mint Chocolate: Use mint-flavored Oreos and dark chocolate chips.
Gluten-Free: Substitute flour with a 1-to-1 gluten-free baking blend.
Seasonal Add-Ins: Add crushed peppermint for the holidays or pastel M&Ms for Easter.
Nutty Surprise: Sprinkle chopped pecans or walnuts into the brownie batter for crunch.

Frequently Asked Questions

Can I use boxed brownie and cookie mixes?
