Introduction

Slutty brownies are a decadent dessert featuring layers of chocolate chip cookie, Oreo cookies, and rich fudgy brownies. This indulgent treat is perfect for any chocolate lover looking to impress friends or family with minimal effort.

A stack of five square dessert bars sits on a white plate over a white marbled surface. Each bar has three clear layers: the bottom layer is light brown with chocolate chips, soft and cookie-like; the middle layer shows whole black and white sandwich cookies embedded within a dense, dark brown chocolate brownie layer; the top layer is a slightly cracked, rich chocolate brownie crust, darker than the middle layer. The bars are piled unevenly, with three bars at the bottom and two resting on top, showing the detailed texture of the chocolate chips and cookies in the cross-section.

Ingredients

3/4 cup unsalted butter (168 grams), softened
1/2 cup brown sugar (105 grams)
1/2 cup white sugar (100 grams)
1 large egg
1 large egg yolk (discard the white)
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour (188 grams)
1/4 teaspoon salt
2/3 cups chocolate chips (120 grams)
28 Oreo cookies
1/2 cup unsalted butter (112 grams), cubed
6 oz dark chocolate (170 grams), 50-70% or semi-sweet
1 cup granulated sugar (200 grams)
2 large eggs
1/2 cup all-purpose flour (63 grams)
1/4 cup cocoa powder (23 grams)
1/2 teaspoon salt

Instructions

Step 1: Preheat your oven to 350°F (180°C) and lightly grease a 9×13 inch (23×33 cm) pan. Line it with parchment paper, leaving an overhang to help lift the brownies later.
Step 2: In a large bowl, beat together the softened butter, brown sugar, and white sugar until well combined.
Step 3: Add the egg, egg yolk, and vanilla extract to the butter mixture, beating well. Remember to discard the extra egg white.
Step 4: With the mixer on low, gradually add the flour and salt. Turn off the mixer and gently fold in the chocolate chips with a spatula or wooden spoon.
Step 5: Spread the cookie dough evenly in the prepared pan using a spatula.
Step 6: Arrange the Oreo cookies on top of the cookie dough, pressing down slightly to cover the surface. You can place 7 rows of 4 cookies plus some halves to fill gaps.
Step 7: Finely chop the dark chocolate. Combine the chopped chocolate and cubed butter in a heatproof bowl and melt in the microwave at medium power in 45-second intervals. Stir between each interval to prevent burning.
Step 8: Let the melted chocolate mixture cool for about 5 minutes. Then, whisk in the eggs and granulated sugar until smooth.
Step 9: Sift together the flour, cocoa powder, and salt. Whisk these dry ingredients into the chocolate mixture until just combined, avoiding lumps.
Step 10: Spoon the brownie batter over the Oreo layer in small dollops, then spread evenly with a spatula. Spreading gradually helps cover the Oreos more easily.
Step 11: Bake the layered brownies for 37-45 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs. Adjust baking time based on your oven and preference for gooeyness.
Step 12: Allow the brownies to cool fully for at least 4 hours. Use the parchment paper overhang to lift them out of the pan before slicing.

Tips & Variations

For extra gooey brownies, slightly underbake by a few minutes and let them set while cooling.
Use double-stuffed Oreos for an even richer middle layer.
Sift the cocoa powder and flour to avoid lumps and create a smoother brownie batter.
Try swapping dark chocolate for milk chocolate if you prefer a sweeter brownie layer.
Ensure your butter is softened for the cookie dough to blend smoothly and create a tender texture.

Storage

Store leftover slutty brownies at room temperature in an airtight container for up to 4 days. If you prefer, you can refrigerate them to extend freshness, but allow them to come to room temperature before serving for the best texture. Reheat slightly in the microwave for a warm, gooey treat.

FAQs

Can I make this recipe in a different sized pan?

Yes, but baking times may vary. A smaller pan will create thicker layers and require longer baking, while a larger pan will thin the layers and bake faster. Keep an eye on the brownies and test doneness with a toothpick.

Can I freeze slutty brownies?

Absolutely. Wrap cooled brownies tightly in plastic wrap or foil and place them in a freezer-safe container. They can be frozen for up to 3 months. Thaw overnight in the refrigerator before serving.
