Sluttier brownies are one of those over-the-top desserts that I make when I want to completely blow people’s minds – these aren’t your ordinary brownies, they’re layers of cookie dough, Oreos, and brownie batter all baked together into one outrageously indulgent treat. The name is cheeky and fun, and honestly, it perfectly describes how extra and decadent these layered brownies are. These 10 sluttier brownie recipe ideas take that viral three-layer concept and transform it into so many delicious variations that you’ll find any excuse to make these show-stopping desserts.

The Classic Sluttier Brownies are the original viral sensation – chocolate chip cookie dough bottom, Oreo middle, and fudgy brownie top. The Oreo Cookie Sluttier Brownies double down on Oreos with cookies mixed into every layer, while the Peanut Butter Cup Sluttier Brownies use everyone’s favorite candy. The Salted Caramel Sluttier Brownies add sweet-salty drizzles, and the Chocolate Chip Cookie Sluttier Brownies emphasize that cookie dough layer. The Nutella Sluttier Brownies swirl in chocolate-hazelnut spread, the Triple Chocolate Sluttier Brownies are for serious chocolate addicts, and the Marshmallow Sluttier Brownies add gooey s’mores vibes. The Biscoff Sluttier Brownies use cookie butter for amazing flavor, while the Holiday Sluttier Brownies get decorated festively for Christmas or special occasions.

What makes sluttier brownies so amazing is how they’re basically three desserts in one – you get cookie, candy, and brownie all in each bite. They’re perfect for potlucks, bake sales, or any time you want to seriously impress people with minimal effort since everything layers together easily. Fair warning though – these are rich, decadent, and absolutely addictive. One square is never enough!

1. Classic Sluttier Brownies

Classic Sluttier Brownies are the kind of dessert I make when I want something playful, indulgent, and wonderfully over the top. There’s a comfort in stacking cookie dough, Oreos, and rich brownie batter, almost like building a dessert that refuses to take life too seriously. These brownies remind me of evenings when I needed something fun to lift my mood, something that felt youthful but still comforting in the way only a layered dessert can be. Each bite holds sweetness, crunch, and chocolate, blending into a treat that feels messy, joyful, and completely satisfying.

Ingredients

• 1 roll chocolate chip cookie dough
• 20 Oreo cookies
• 1 batch brownie batter (boxed or homemade)
• 1 teaspoon vanilla
• Pinch of salt

Steps

Step 1: Press the cookie dough into the bottom of a lined baking dish, smoothing it gently to form an even layer. As you press it down, the dough warms slightly under your hands, becoming soft and familiar. This layer becomes the foundation—sweet, comforting, and nostalgic—reminding you of simple moments spent baking cookies on quiet afternoons.

Step 2: Arrange the Oreo cookies in neat rows over the cookie dough. Their crisp edges and chocolate scent create a playful contrast to the soft base. As you lay them out, there’s a small joy in knowing these cookies will soften inside the brownies, turning into a sweet surprise hidden between layers.

Step 3: Pour the brownie batter over the Oreos, letting it flow slowly between the cookies. The rich, glossy batter settles like a blanket, bringing all the layers together. It feels almost therapeutic watching it spread, knowing it will bake into something warm and indulgent.

Step 4: Bake at 350°F (175°C) for 35–40 minutes. The edges will set first while the center stays slightly gooey, which is exactly what gives Sluttier Brownies their signature indulgence. As they bake, the kitchen fills with a comforting chocolate aroma that feels like a warm, familiar hug.

Step 5: Cool before slicing. The layers settle into each other, forming a soft cookie bottom, a melting Oreo center, and a fudgy brownie top. Each bite feels joyful and messy—a dessert meant for moments when you welcome a bit of sweetness and chaos.
