Creating these magnificent slutty brownies is a straightforward process, even for beginner bakers. Follow these steps to assemble your decadent triple-layer treat.

1. Prepare the Brownie Layer

  • Start by melting 10 tablespoons of unsalted butter in a medium saucepan over medium heat. Once the butter is melted, remove the saucepan from the heat.
  • Add 1 ¼ cups white sugar and ¾ cup cocoa powder to the melted butter. Whisk these ingredients together until well combined and smooth.
  • Stir in ½ teaspoon kosher salt and 2 teaspoons vanilla extract, mixing well.
  • Next, add the 2 large eggs, whisking continuously and vigorously until the eggs are fully incorporated and the batter is smooth.
  • Finally, stir in ½ cup all-purpose flour until just combined, being careful not to overmix. Set this rich brownie batter aside.
  • In a large mixing bowl, using a stand mixer with the paddle attachment or a hand mixer, cream together ½ cup room-temperature unsalted butter with ¼ cup brown sugar and ¾ cup white sugar.
  • Beat until the mixture is light and fluffy, about 2-3 minutes. Add 1 large egg and 1 ¼ teaspoons vanilla extract, mixing until just combined. Be sure to scrape down the sides of the bowl to incorporate everything.
  • In a separate small bowl, whisk together 1 ¼ cups all-purpose flour, ½ teaspoon salt, ½ teaspoon baking soda, and ½ teaspoon baking powder.
  • Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Fold in 1 cup semi-sweet chocolate chips by hand.
  • Set this delicious cookie dough aside.

3. Assembly and Baking

  • Preheat your oven to 350°F (175°C). Line the bottom of a 9×9 inch baking pan with parchment paper or aluminum foil, leaving an overhang on the sides to easily lift out the brownies later.
  • Spray the lining lightly with non-stick baking spray for extra insurance. Press the prepared cookie dough evenly into the bottom of the lined 9×9 inch baking pan, forming a solid base for your slutty brownies.
  • Arrange a single layer of Oreo cookies directly on top of the cookie dough, placing them close together but without overlapping.
  • You want a consistent crunchy layer. Carefully pour the brownie batter over the Oreo layer, using a spatula to gently spread it evenly across the entire pan, making sure to fully cover all the Oreos. Bake for 35-40 minutes.
  • To check for doneness, insert a knife or a wooden skewer into the center of the brownie layer; it should come out with moist crumbs but no wet batter. If it’s still wet, bake for another 5 minutes.
  • Once baked, let these glorious layered bars cool completely in the pan for at least 2 hours before attempting to slice them. Cooling ensures clean, picture-perfect cuts.

Pro Tips & Troubleshooting

  • Pan Size Matters: Always use a 9×9 inch metal baking pan. Glass or ceramic pans can bake differently and may require adjusted times. Research suggests that different baking pan materials affect heat distribution and baking times.
  • Cooling is Crucial: For clean, neat squares, allow your slutty brownies to cool for at least 2 hours, or even longer. Rushing this step will result in a messy, crumbly slice.
  • Prevent Sticking: Even with parchment paper, a light spray of non-stick baking spray on the lining is a lifesaver.
  • Avoid Scrambling Eggs: When adding eggs to the hot brownie mixture, whisk continuously and quickly to prevent them from cooking prematurely.
  • Bubbling Concerns: Some bubbling is normal, especially around the edges. Uneven layers can sometimes cause more aggressive bubbling in spots; just ensure your layers are as flat as possible.
  • Adjust Baking Time: Oven temperatures vary. Trust the knife test and adjust baking time as needed for your specific oven.

Serving, Storage, and Variations

These slutty brownies are versatile and delicious in many ways!

Serving Suggestions

Serve these decadent treats warm with a scoop of vanilla bean ice cream for an extra indulgent experience. For neatly sliced squares, allow them to cool completely before serving at parties, potlucks, or family gatherings. They’re always a showstopper.

Storage Instructions

Store leftover slutty brownies in an airtight container at room temperature for 2-3 days. For extended freshness, refrigerate them for up to a week. You can also freeze individual squares in an airtight container for up to 3 months; thaw at room temperature before enjoying.

Flavor Variations

Get creative with your triple-layer bars!

  • Use flavored Oreos like mint, peanut butter, or golden Oreos.
  • Swap the chocolate chip cookie dough for a sugar cookie dough base.
  • Fold in chopped nuts, pretzels, or even M&M’s into the cookie dough.
  • Try “Slutty Blondies” by using a blondie base instead of a brownie.
  • Elevate with a S’mores twist: graham cracker crust, chocolate, and toasted marshmallows.

Frequently Asked Questions

What are slutty brownies?

Slutty brownies are a popular decadent dessert bar featuring three distinct layers: a bottom layer of chocolate chip cookie dough, a middle layer of whole Oreo cookies, and a top layer of rich, fudgy brownie. They’re known for being incredibly rich and indulgent.

Why are my brownies bubbling?

Some bubbling is normal during baking, especially around the edges where the batter meets the hot pan. Excessive bubbling might indicate slightly uneven layers or a hot spot in your oven; ensure all layers are spread as flat as possible for best results.

Can I use a different size baking pan?

It’s strongly recommended to stick to a 9×9 inch baking pan for this slutty brownies recipe. Using a different size will alter the layer thickness and baking time significantly, potentially leading to under or overcooked results.

How do I get clean cuts?

The secret to clean cuts is patience! Allow the brownies to cool completely in the pan for at least two hours (or even overnight) before slicing. A plastic knife or a sharp, warm knife wiped clean between each cut also helps.

Conclusion

These ultimate slutty brownies are more than just a dessert; they’re an experience. With their irresistible layers of chewy cookie, crunchy Oreo, and fudgy brownie, they are guaranteed to bring smiles and satisfy even the biggest sweet tooth. Don’t be intimidated by the layers; this recipe is straightforward and incredibly rewarding for beginner bakers.
