These Oreo brownies came about because Liam found a sleeve of smashed Oreos in our pantry and didn't want to throw them away. I was already making brownies for a school bake sale, so I figured why not chop up those broken cookies and see what happened. The result was incredible - rich, fudgy brownies loaded with chunks of Oreos that somehow made everything taste even more chocolatey. Liam took one bite and said "Mom, we're never making regular brownies again!"
Why You'll Love These Oreo Brownies
These brownies have taken over as our go-to dessert for pretty much everything. They're so easy to make - if you can handle regular brownies, you can definitely handle these. The trickiest part is chopping up the Oreos, and even that's more fun than work. Liam loves the cookie-smashing job, though I've learned to give him his own bowl because he eats half the cookies before they make it into the batter.
What blows my mind is how much better these taste than plain brownies. The Oreos pump up the chocolate flavor and add that cookies-and-cream taste that makes every bite more exciting. They're rich enough to cure any chocolate craving but not so sweet that you feel gross after eating them. Okay, maybe after eating three, but that's on you.

Top Tip
- I've screwed up these Oreo Brownies enough times to know exactly what goes wrong! The biggest mistake is chopping the Oreos too small. The first few batches I made, I got obsessed with making perfect tiny pieces and ended up with Oreo dust that just vanished into the brownie batter. You want actual chunks that you can bite into - some pieces should be almost half a cookie so you get that satisfying crunch when you eat them.
- Don't bake these to death, even if the middle looks a little wet. Brownies keep cooking on the hot pan after you pull them out, and these especially need to stay fudgy to balance the crunchy cookies. I used to bake them until a toothpick came out spotless, and they'd be dry and boring instead of rich and gooey. Now I take them out when there are still some moist crumbs on the toothpick.
What to Serve With Oreo Brownies
These Oreo brownies are rich enough to stand on their own, but there are some combinations that take them from great to absolutely incredible. The classic pairing is vanilla ice cream - the cold, creamy vanilla balances out all that intense chocolate and cookie flavor perfectly. Liam's favorite is making brownie sundaes by warming up a square in the microwave for about 20 seconds and topping it with a scoop of vanilla ice cream and maybe some chocolate sauce.
For grown-up gatherings, these Oreo brownies are amazing with a cup of strong coffee or espresso. The bitter coffee cuts through the sweetness and brings out the chocolate flavors even more. I've served them at dinner parties with coffee and gotten rave reviews every time. They're also surprisingly good with a cold glass of milk - sometimes the simple combinations are the best ones.
FAQ
Can I put Oreos in brownie mix?
Absolutely! You can add chopped Oreos to any brownie mix - boxed or homemade. Just fold about 15-20 chopped cookies into your prepared brownie batter before baking. The key is chopping them into chunks, not crumbs, so you get actual cookie pieces to bite into. I've done this with store-bought mix when I'm short on time and it works perfectly.
How do you make Oreo brownies?
Make your regular Oreo brownies batter, then gently fold in roughly chopped Oreo brownies before baking. The trick is not overmixing - you want visible chunks throughout the brownies, not cookie dust. Chop about 15-20 cookies into bite-sized pieces, fold them into the batter with just a few gentle turns, then bake as usual. Super simple but incredibly delicious.
What is the rarest Oreo flavor?
The rarest Oreos are usually limited edition or international flavors that aren't available everywhere. Some of the hardest to find include wasabi, green tea, and various fruit flavors that are only sold in certain countries. But honestly, for brownies, the classic chocolate Oreos work best. Liam tried convincing me to use some weird cotton candy Oreos once - not recommended!
What does the O in Oreo stand for?
This is actually a common myth - the letters in Oreo brownies don't stand for anything! The name was just created by the original Nabisco company in 1912. Some people think it comes from the French word "or" meaning gold, or that it's related to the shape, but there's no official meaning. Just a catchy name for a great cookie that happens to make amazing brownies.
