Oreo Brownies are what happens when a fudgy brownie meets a thick layer of cookies-and-cream fudge, and honestly, they might ruin every other brownie for you. I made a pan for a weekend bake sale and Maddie begged me to keep them, so now they are our go-to when we need a dessert that disappears fast. If you love our no bake Oreo cheesecake, these bars are the handheld version.
A boxed brownie base plus a white chocolate cream cheese fudge topping means big bakery flavor with almost no effort.

Why This Recipe Works
Click to see the technique science
- Two desserts in one. You get a rich, fudgy brownie base and a thick, creamy Oreo fudge topping in every single square.
- A boxed mix shortcut. Starting with a fudge brownie mix means no fussy from-scratch baking, so anyone can make these.
- That cookies-and-cream flavor. Crushed Oreos folded into a white chocolate cream cheese fudge give these bars big cookies-and-cream flavor.
- Make-ahead friendly. They need to chill to set, which makes them perfect for prepping the day before a party or bake sale.
- Feeds a crowd. One 9×13 pan cuts into 20 rich squares, so they are ideal for potlucks and holidays.
- No-fail topping. The white chocolate stabilizes the cream cheese fudge so it slices clean and holds its shape.

Key Ingredients
A boxed mix and a handful of pantry staples make these Oreo Brownies come together fast.
- Fudge brownie mix: The shortcut to a rich, fudgy base. Bake it according to the box using eggs, water, and melted butter.
- Cream cheese: Softened to room temperature so it whips up smooth and lump-free for the fudge topping.
- White chocolate chips: Melted and beaten in, they sweeten the topping and help it set up firm enough to slice.
- Powdered sugar: Sweetens the fudge and gives it that smooth, creamy texture.
- Oreos: Half get crushed into the topping and half crumbled on top for that signature cookies-and-cream look, just like in our no bake Oreo cheesecake.

Variations and Substitutions
These Oreo Brownies are easy to switch up.
- Use a different Oreo flavor like Golden, Mint, or Peanut Butter for a fun twist.
- Make the brownie base from scratch if you prefer, then top as directed.
- Add a drizzle of melted chocolate or a sprinkle of mini chocolate chips over the top.
- Swap the white chocolate for melted semi-sweet chocolate for a double-chocolate topping, like our chocolate cream cheese frosting.
How to Make Oreo Brownies
- Preheat the oven to 350 degrees and spray a 9×13 inch pan with cooking spray. Mix the brownie mix with eggs, water, and melted butter until there are no dry patches.
- Pour the batter into the prepared pan, smooth the top, and bake according to the box directions. Let the brownies cool completely before topping.
- Place half of the Oreos in a ziplock bag and crush them into small chunks with a rolling pin or your hands.
- Cream the room-temperature cream cheese until smooth, then slowly beat in the powdered sugar, melted white chocolate, and vanilla until fluffy.
- Fold the crushed Oreos into the cream cheese fudge, scraping the sides of the bowl as needed so everything is evenly mixed.
- Spread the Oreo fudge over the cooled brownies, crumble the remaining Oreos on top, then cover and chill for about 4 hours until set. Slice and serve.
Recipe Tips & Tricks
- Cool the brownies completely before adding the topping, or the fudge will melt and slide off.
- Use room-temperature cream cheese so the fudge whips up smooth with no lumps.
- Do not overbake the brownie base, pulling it when a toothpick has a few moist crumbs for the fudgiest result.
- Chill until fully set, at least 4 hours, so the bars slice cleanly.
- Wipe the knife between cuts with a warm, damp cloth for neat, bakery-style squares.
- Store in the fridge, since the cream cheese topping needs to stay cold.
Serving Ideas and Suggestions
These Oreo Brownies are rich, so cut them into small squares. Serve them cold or let them sit at room temperature for a few minutes to soften slightly for the fudgiest bite.
They are a natural for a dessert table. Set them next to our Oreo dirt cake and a plate of cosmic brownie cookies for a cookies-and-cream spread.
A cold glass of milk is the classic pairing, or add a scoop of vanilla ice cream and a drizzle of chocolate for a plated dessert like our chocolate earthquake cake.
Store the bars in an airtight container in the fridge for up to 5 days, or freeze them for up to 3 months. To freeze, cut them into squares, flash freeze on a tray, then wrap and store. Thaw in the fridge before serving so the topping stays creamy.
Oreo Brownies FAQs
Yes, because the topping is made with cream cheese, Oreo Brownies should be stored in the refrigerator. Keep them in an airtight container for up to 5 days. Let them sit at room temperature for a few minutes before serving so the fudge softens slightly.
Absolutely. Any 9×13 batch of fudgy brownies works as the base, whether from a mix or from scratch. Just be sure they are baked and completely cooled before you add the Oreo fudge topping so it sets properly.
Chill the bars until fully set, at least 4 hours, then use a sharp knife and wipe it clean with a warm, damp cloth between each cut. Cold, firm bars and a clean blade give you neat, bakery-style squares.
Yes. Cut them into squares, flash freeze on a tray until firm, then wrap tightly and store in a freezer bag for up to 3 months. Thaw them in the refrigerator overnight before serving so the cream cheese topping stays smooth.
Classic Oreos are perfect, but this recipe is a great way to use fun flavors too. Golden Oreos, Mint, Double Stuf, or Peanut Butter Oreos all work well. Use whatever you love, keeping half crushed for the topping and half crumbled on top.
The white chocolate is what firms up the topping, so be sure to melt it and beat it in fully. If the topping still seems soft, chill the bars longer. Very warm kitchens can also keep them soft, so keep them refrigerated until serving.

Dana….I am your Mom’s cousin down here in Florida. My Grandson loves Oreos so this will be perfect for him. Love love your posts. Great recipes with easy to follow instructions. Keep up the fantastic job.❤️😎❤️😎
Unfortunately, it wouldn’t be a “fudgy” topping without the cream cheese. But, if you did use whipped topping in place, it would be like a fluffy oreo topping which would be completely amazing and I may need to try that for myself! I would just mix the Oreos with the whipped topping, you don’t need the other ingredients then.
Hi! This looks delicious but I can’t have cream cheese, is there a good substitute, or maybe a whipped topping?
