How to Make Slutty Brownies
- Baking pan (25×25 cm/10×10 in)
- Mixing bowls
- Microwave-safe bowl
- Kitchen scale
INGREDIENTS
- 30 Oreo cookies
- Cookie Dough:
- 1 cup/225 grams soft unsalted butter
- ¾ cup/150 grams brown sugar
- ¾ cup/150 grams white sugar
- 2 large eggs/100 grams
- 2 ½ cups/315 grams all-purpose flour
- 1 ½ cups/300 grams chocolate chips
- ½ teaspoon baking soda
- Pinch of salt
- Brownie Layer:
- 7 ounces/200 grams unsalted butter
- 7 ounces/200 grams bittersweet chocolate
- 1 ½ cups/280 grams white sugar
- 3 large eggs
- ¾ cup/100 grams all-purpose flour
- ¼ cup unsweetened cocoa powder
- Pinch of salt
INSTRUCTIONS
- Preheat the oven to 350°F/180°C. Line a 25×25 cm/10×10-inch pan with parchment paper.
- Make the cookie dough: Beat butter and white sugar in a mixing bowl until smooth. Add eggs and mix until incorporated. Add flour, baking soda, and salt; mix to a sticky, uniform dough. Fold in chocolate chips gently. Press dough evenly into the prepared pan using damp hands or a small offset spatula.
- Arrange whole Oreo cookies in a single layer on top of the cookie dough to cover completely.
- Melt chocolate and butter together in a microwave using 30-second pulses until smooth. Whisk in sugar, then add eggs and mix until uniform. Fold in flour, cocoa, and salt until batter is smooth.
- Pour brownie batter gently over the Oreo layer, spreading evenly. Bake for 40–50 minutes, or until a skewer inserted comes out with moist crumbs. Avoid overbaking to keep brownies fudgy.
- Freeze brownies for about 3 hours. Once frozen, remove from the pan and cut into squares. Store in an airtight container in the refrigerator for up to 1 week.

FAQ
What is the best type of chocolate to use when making slutty brownies?
The type of chocolate you choose significantly impacts the flavor and texture. For the brownie layer, a high-quality bittersweet or semi-sweet chocolate works best, as it provides a deep, rich cocoa flavor that balances the sweetness of the cookie dough and Oreos. Chocolate with at least 60% cocoa is ideal because it melts smoothly and gives the brownies a fudgy, luxurious texture. Using lower-quality chocolate or chocolate chips with stabilizers can affect the melting process and result in a less cohesive brownie layer.
For the cookie dough, semi-sweet chocolate chips or chunks work well, adding pockets of melted chocolate throughout the slutty brownies. Choosing quality chocolate is essential when learning how to make slutty brownies that are decadent and visually appealing.
How can I make these slutty brownies dairy-free?
You can substitute butter with a dairy-free alternative when learning how to make slutty brownies, but it requires careful selection to maintain texture and flavor. Plant-based butters or vegan spreads made from cashews or oats work best because they mimic the fat content of butter, which helps create the cookie dough and fudgy brownie layers. Coconut oil can be used as a substitute, though it may slightly alter the flavor.
When substituting, use the same weight as the butter in the original recipe for consistent results. Keep in mind that the melting and mixing properties may differ, so monitor the dough and brownie batter carefully

How long should I bake the slutty brownies to achieve a fudgy texture?
Baking time is crucial to achieve the perfect fudgy texture when making slutty brownies. Generally, 40–50 minutes at 350°F/180°C is recommended, but ovens vary, so checking is important. Insert a skewer or toothpick into the center around 40 minutes; it should come out with moist crumbs rather than clean, indicating a soft, fudgy center. Overbaking dries out the brownie layer, which reduces the indulgent, gooey experience that slutty brownies are known for. For a thicker pan or larger portion, add a few minutes, but always monitor closely.
Do I need to freeze the brownies before slicing them?
Freezing is highly recommended to achieve clean, precise cuts without squishing the layers. The cookie dough, Oreos, and brownie layers create a thick, soft dessert that can be difficult to cut when fresh from the oven. Freezing firms up the brownies, making it easy to slice uniform squares without smearing chocolate or breaking the cookie layer. Typically, freezing for 3 hours is sufficient, but longer freezing can help if you plan to serve them later.
How to make slutty brownies ahead of time for an event
You can prepare the cookie dough, Oreo, and brownie layers in advance, bake, and then freeze them until needed. Freezing ensures the layers remain intact and allows for easy slicing shortly before serving. You can even bake them a day in advance, cool completely, then store in the refrigerator for up to a week.

How can I make these slutty brownies gluten-free?
You can easily make them gluten-free by substituting the all-purpose flour in both the cookie dough and brownie layers with a gluten-free flour blend. Choose a blend designed for baking that includes xanthan gum or another binding agent to maintain structure. Measure carefully and avoid overmixing, as gluten-free flours can behave differently from traditional wheat flour. The cookies and brownies may have a slightly different texture but will still retain the layered, decadent quality of traditional slutty brownies.
What is the best way to serve the brownies?
Freezing before slicing ensures clean edges, making presentation appealing for parties. Serve slightly chilled or at room temperature for the ideal texture, and consider pairing with ice cream, whipped cream, or fresh berries to elevate the experience.
