Description
Slutty Brownies are an indulgent dessert featuring three decadent layers: a buttery chocolate chip cookie base, a layer of classic Oreo cookies, and a rich, fudgy brownie top. Baked together to create a gooey, flavorful treat, these brownies combine the best of cookies and brownies in one pan for a crowd-pleasing dessert perfect for parties or special occasions.
Ingredients
Chocolate Chip Cookie Layer
- 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 bean paste
- 1 1/2 cups all-purpose flour (188 grams)
- 1/4 teaspoon salt
- 2/3 cup chocolate chips (120 grams)
Oreo Layer
- 28 Oreo cookies
Brownie Batter
- 1/2 cup unsalted butter (112 grams), cubed
- 6 oz dark chocolate (170 grams) (50-70% cacao 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
- Preheat the oven: Set your oven to 350°F (180°C) to prepare it for baking the Slutty Brownies evenly.
- Prepare the baking pan: Lightly grease a 9×13 inch (23×33 cm) pan, then line it with parchment paper leaving an overhang on the sides to help with easy removal. Greasing first helps the parchment stick properly.
- Make the chocolate chip cookie dough: In a large bowl, beat the softened butter, brown sugar, and white sugar together until thoroughly combined and creamy.
- Add eggs and vanilla: Beat in one whole egg, one egg yolk (discard the second egg white), and the vanilla bean paste until fully incorporated.
- Add dry ingredients: With the mixer on low speed, gradually beat in the all-purpose flour and salt until just combined. Then turn off the mixer and fold in the chocolate chips gently using a rubber spatula or wooden spoon.
- Form the cookie layer: Spoon the cookie dough evenly into the prepared pan and spread it smooth with a spatula.
- Arrange Oreo cookies: Place the Oreo cookies evenly on top of the cookie dough layer, pressing them down slightly to stick. Use 7 rows of 4 cookies, adding some half cookies if necessary to cover the entire surface.
- Prepare the brownie batter – melt chocolate and butter: Finely chop the dark chocolate. Place the chocolate and cubed butter in a heatproof bowl and microwave on medium power in 45-second intervals, stirring between each, until melted and smooth. Avoid high power to prevent burning or graininess.
- Cool and combine eggs and sugar: Let the chocolate-butter mixture cool for about 5 minutes, then whisk in the eggs and granulated sugar until the mixture is smooth.
- Add dry brownie ingredients: Sift together the flour, cocoa powder, and salt to remove lumps and whisk into the brownie batter just until combined.
- Layer the brownie batter: Spoon the brownie batter in dollops over the Oreo layer and spread it out smoothly with a spatula. Spreading incrementally helps cover Oreos evenly without mixing layers.
- Bake the Slutty Brownies: Place the pan in the preheated oven and bake for 37 to 45 minutes. Check doneness by inserting a toothpick; it should come out clean or with a few moist crumbs depending on your preferred gooeyness.
- Cool completely: Allow the brownies to cool fully for at least 4 hours before slicing to ensure clean cuts and optimal texture.
- Slice and store: Use the parchment paper overhang to lift the brownies out of the pan onto a cutting board. Cut into 18 servings and store any leftovers at room temperature in an airtight container for up to 4 days.
Notes
- Discard the white from the second egg yolk as the recipe only requires one whole egg plus one yolk for the cookie layer.
- Grease the pan before lining with parchment to help the paper stay in place, making removal after baking easier.
- Microwave the chocolate and butter mixture carefully at medium power to avoid graininess or burning.
- Allow the brownies to cool fully before slicing to prevent them from falling apart.
- If you prefer a more gooey brownie, check earlier; for firmer brownies, bake closer to 45 minutes.
- Use parchment paper with overhang for easy lifting out of the baking pan.
