These insanely delicious Oreo brownies are extra fudgy, stuffed with Oreo cookies, and topped with even more Oreos. Made from scratch and oh so easy! 
If you love Oreo cookies and extra fudgy brownies – then you need to try these Oreo cookie brownies. It’s a simple, from-scratch brownie recipe that makes extra thick, slightly gooey, completely decadent brownies.
Plus – when you combine Oreo cookies and fudge brownies can you really go wrong???
Oreo Brownies Recipe
To make these Oreo cookie brownies – it’s a super easy, one bowl, kind of deal. First, we make the brownie batter:
- Melt together the butter and sugar.
- Whisk in the eggs and vanilla extract.
- Gently fold in the cocoa powder, salt, and flour.
We’re using butter for more flaver and cocoa powder for the chocolate. You’ll notice that the recipe calls for 2 eggs plus 1 extra egg yolk (you can discard the white of the third egg). The extra egg yolk makes the brownies supremely fudgy and dense.
Assembling the Brownies
These brownies are stuffed with Oreos AND have crushed Oreos on top.
- Spoon about half the batter into a lined 8×8 inch square pan and spread it out so the bottom is covered.
- Then place a layer of Oreos over top and gently press them down slightly. You’ll need 16 Oreos.
- Spoon the rest of the batter over top and spread smooth so that the Oreos are covered.
- Crush (or chop) 4-5 more Oreo cookies, and sprinkle them on top.
Baking Brownies
This recipe will take about 30-35 minutes to bake, depending on your oven. The top should no longer look shiny when you take it out, and an inserted toothpick should come out clean or with a few moist crumbs. If you like your brownies extra gooey, you could take them out when the toothpick is slightly damp still.
Then you’ll need to wait for the brownies to cool 100% before cutting into them. Otherwise, you can end up with a bit of a mess. A delicious mess for sure, but pretty hard to serve. 
Now – a few common questions I get about these brownies…
- What kind of cocoa powder should I use? For this recipe, I used dutch processed. You could also use natural too – they just won’t be as dark in color.
- Can I double the recipe? Yup. Just use a 9×13 inch pan.
- Can I use a 9×9 inch square pan? For sure, the bake time will just be a bit shorter. I think about 30 minutes.
Oreo Brownies Using Brownie Mix
If you’d like to use brownie mix from a box instead (although I highly recommend using the from-scratch recipe below) – you’ll simply need to make the brownie batter according to the package instructions. Then follow the assembly instructions in the recipe card below (make sure to use the same size pan as listed on the box of brownies). Then bake according to the package instructions.
Ok – let’s just take a moment to recap why you’ll LOVE these Oreo brownies:
- Extra fudgy

OMGoodness, just finished making 3 double batches of these for the kiddos at church tomorrow. Of course I had to sneak one. Without a doubt this will be my go to brownie recipe even without the oreos. So easy to whip up. very fudgy and moist. Just can’t say enough about this recipe. SO GOOD I baked a 9×13 for 24 min. and it was perfect. I used mini m&m’s on top cause was short on cookies and I know the kids will like that. Thank you so very much for this recipe!!
