Parchment Paper
Makes lifting the finished brownies from the pan effortless and simplifies cleanup.

Cooling Rack
Allows the brownies to cool evenly before slicing for clean, professional-looking bars.

Preparation Tips

• Let the butter soften naturally for easier creaming.
• Use room-temperature eggs for a smoother cookie dough.
• Line the baking pan with parchment paper, leaving overhang on both sides.
• Press the cookie dough into an even layer to prevent uneven baking.
• Arrange the Oreos tightly together with minimal gaps.
• Chill the cookie layer for 10 minutes if your kitchen is warm.
• Avoid overmixing once the flour is added.
• Allow the brownies to cool completely before cutting.

Ingredients for Slutty Brownies

Chocolate Chip Cookie Layer

• ¾ cup unsalted butter, softened (168 g)
• ½ cup brown sugar (105 g)
• ½ cup granulated sugar (100 g)
• 1 large egg
• 1 large egg yolk
• 1 teaspoon vanilla extract
• 1½ cups all-purpose flour (188 g)
• ¼ teaspoon salt
• ⅔ cup chocolate chips (120 g)

Oreo Layer

• 28 Oreo cookies

Brownie Layer

• Brownie batter of your choice (homemade or prepared according to package directions, enough for a 9×13-inch pan)

Step 1: Prepare the Baking Pan

Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving enough overhang to lift the brownies out later.

Step 2: Cream the Butter and Sugars

In a large bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2–3 minutes.

Step 3: Add the Wet Ingredients

Mix in the whole egg, extra egg yolk, and vanilla extract until fully incorporated.

Step 4: Add the Dry Ingredients

Stir in the flour and salt just until no dry streaks remain. Fold in the chocolate chips.

Step 5: Form the Cookie Layer

Spread the cookie dough evenly across the prepared baking pan. An offset spatula or lightly greased hands make this easier.

Step 6: Add the Oreo Layer

Arrange the 28 Oreo cookies in a single, tightly packed layer over the cookie dough.

Step 7: Prepare the Brownie Batter

Prepare your favorite brownie batter according to its instructions, or use homemade brownie batter sized for a 9×13-inch pan.

Step 8: Add the Brownie Layer

Pour the brownie batter evenly over the Oreos, gently spreading it to cover the cookies completely.

Step 9: Bake

Bake for 35–45 minutes, or until the brownie layer is set and a toothpick inserted near the center comes out with a few moist crumbs.

Step 10: Cool and Slice

Cool completely in the pan before lifting out with the parchment paper. Slice into squares and serve.

Notes

• Use regular Oreos rather than Double Stuf for the best layer balance.
• Don’t overbake; slightly underbaked brownies stay fudgier after cooling.
• Chill before slicing if you want perfectly clean edges.
• Mix in white chocolate chips, peanut butter chips, or chopped nuts for extra flavor.
• Sprinkle flaky sea salt on top after baking for a gourmet finish.

Watch Out for These Mistakes While Cooking

• Using melted butter instead of softened butter for the cookie dough.
• Overmixing the flour, resulting in a tougher cookie layer.
• Leaving large gaps between the Oreo cookies.
• Overbaking, which dries out the brownie layer.
• Cutting while still warm, causing messy slices.
• Using too much brownie batter, which may overflow.
• Forgetting parchment paper, making removal difficult.
• Measuring flour incorrectly by packing it into the cup.

Frequently Asked Questions

Can I use homemade brownie batter?

Absolutely! Homemade brownie batter works wonderfully and often gives an even richer, fudgier finish than boxed mixes.

Can I make Slutty Brownies ahead of time?

Yes. In fact, they often taste even better the next day after the layers have fully set.

Which Oreos work best?

Classic Oreo cookies are the traditional choice, but Golden Oreos, Mint Oreos, Peanut Butter Oreos, or seasonal flavors also make delicious variations.

How do I know when they’re done baking?

The edges should be set, and a toothpick inserted into the brownie layer should come out with a few moist crumbs. Avoid waiting until it’s completely clean, as that can mean the brownies are overbaked.

Why are my brownies falling apart when sliced?

They likely haven’t cooled long enough. Let them cool completely—or chill them in the refrigerator for 30–60 minutes—for cleaner cuts.

Can I freeze Slutty Brownies?

Yes. Wrap individual bars tightly in plastic wrap, then place them in a freezer-safe container or freezer bag. They keep well for up to 3 months.

Can I add extra mix-ins?

Definitely. Chopped walnuts, pecans, peanut butter chips, white chocolate chips, toffee bits, or mini marshmallows are all excellent additions.

What’s the best way to get perfectly clean slices?

Use a sharp knife and wipe it clean between each cut. Chilling the brownies before slicing also helps create neat, bakery-style squares.
