Introduction

Slutty brownies are an indulgent treat featuring layers of chocolate chip cookie dough, Oreos, and rich brownie batter. These decadent bars combine three beloved desserts into one irresistible creation. Perfect for satisfying any sweet tooth craving.

Three square dessert bars are stacked on a white plate, each with four layers. The bottom layer is light golden brown with a soft cookie dough texture and scattered chocolate chips. Above it is a thin layer of a dark chocolate sandwich cookie with a white cream filling. The third layer is dark brown and fudgy, with a dense brownie texture. The top layer is a lighter, cracked brownie crust in a rich chocolate brown color. The background is a white marbled texture. photo taken with an iphone --ar 4:5 --v 7

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 the oven to 350°F (180°C). Lightly grease a 9×13 inch (23×33 cm) pan, then line it with parchment paper, leaving an overhang on the sides. Greasing first helps the paper stick.
Step 2: Make the chocolate chip cookie layer: In a large bowl, beat together the softened butter, brown sugar, and white sugar until combined.
Step 3: Beat in the egg, the additional egg yolk (discard the white), and vanilla extract until smooth.
Step 4: With the mixer on low, gradually add the flour and salt. Turn off the mixer and fold in the chocolate chips using a spatula or wooden spoon.
Step 5: Spread the cookie dough evenly into 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 cover completely.
Step 7: Make the brownie batter: Finely chop the dark chocolate. In a heatproof bowl, microwave the chocolate and cubed butter in 45-second intervals on medium power, stirring after each. Avoid high power to prevent burning.
Step 8: Let the chocolate mixture cool for about 5 minutes, then whisk in the eggs and granulated sugar until well combined.
Step 9: Whisk the flour, cocoa powder, and salt into the chocolate mixture until just combined. Sift the dry ingredients first if they are lumpy.
Step 10: Spoon the brownie batter over the Oreo layer in dollops, then gently spread it out to cover the entire surface evenly.
Step 11: Bake the assembled layers for 37-45 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Baking time depends on your oven and preferred fudginess.
Step 12: Allow the brownies to cool fully, at least 4 hours, before slicing. Use the parchment paper overhang to lift the brownies out of the pan and place them on a cutting board for clean slices.

Tips & Variations

For a cleaner slice, chill the brownies in the fridge after they cool to firm up the layers.
Swap Oreos for your favorite sandwich cookies or add chopped nuts to the brownie batter for added texture.
If you prefer softer cookies, slightly underbake the cookie dough layer before adding the Oreos and brownie batter.

Storage

Store leftover slutty brownies at room temperature in an airtight container for up to 4 days. They can also be refrigerated to keep fresh longer; allow them to come to room temperature before serving. Reheat briefly in the microwave if desired for a gooey texture.

FAQs

Can I use regular chocolate instead of dark chocolate?

Yes, you can use milk chocolate or semi-sweet chocolate instead of dark chocolate, but the flavor will be sweeter and less intense. Choose based on your taste preference.

Can I make these brownies ahead of time?

Absolutely! Make them a day ahead to allow the layers to set properly. They store well and may even taste better the next day once the flavors meld.
