These better than ever Oreo brownies are rich, fudgy, and incredibly easy to make. My recipe squeezes almost an entire pack of Oreos into one batch for the best tasting brownies you’ve ever had! Recipe includes a how-to video!

New & Improved Oreo Brownies

As of today, I’ve shared more than 20 brownie recipes on the blog…can you believe that?! From my cheesecake brownies to my buckeye brownies, I’ve experimented with nearly every possible way to enjoy these fudgy squares. Today the saga continues with these new and improved Oreo brownies!

My new changes to the recipe:

Swapped natural cocoa with Dutch process cocoa (and we will bloom it for extra flavor!).
Whipped the eggs and sugar separately for shiny, crackly, brownie tops.
Used a fun, new technique to create a bold, distinct Oreo layer (similar to what I do with my dirty brownies!).

I wanted something a bit more unique than my classic homemade brownies from scratch with Oreos mixed in (though that’s still delicious, and if you’re looking for the original, that’s all you need to do). I’m so pleased with how they turned out!

What You Need

You’re just 10 ingredients away from irresistibly fudgy and chocolatey Oreo brownies. Not only is this recipe incredibly easy, but it also uses ingredients you will likely already have in your pantry:

Oreos. I used classic Oreo cookies, but feel free to substitute your favorite variety (there are so many to choose from now!). Mint, peanut butter, or birthday cake Oreos would make delicious Oreo brownies. You could even use my homemade Oreo cookies, if you want to go 100% homemade!
Cocoa. I like to use Dutch process cocoa here for a deeper flavor, but natural cocoa will work too. Whichever you use, make sure to add the cocoa when the butter and chocolate are still warm; this is how we will bloom the cocoa and enhance its flavor.
Eggs. Crack your eggs in a separate bowl and whisk them vigorously with the sugar. This step is what creates those crinkly meringue-esque brownie tops!
Chocolate. We’ll start with a melted semisweet chocolate bar and also add mini chocolate chips into the batter (clearly I can never have enough chocolate). If that’s too much chocolate for you, you can always leave out the mini chocolate chips.

SAM’S TIP: You can either melt your butter and chocolate in the microwave or on the stove in a double boiler. Make sure to chop them both beforehand so they melt evenly.

Remember, this is just an overview of the ingredients I used and why. For the full recipe please scroll down to the bottom of the post!

How to Make Oreo Brownies

Melt the chopped chocolate and butter together using either a microwave or a double boiler, then immediately stir in the cocoa powder.
Vigorously whisk together the eggs and sugar in a separate bowl until lightened in color, then drizzle in the melted chocolate mixture. Stir in the vanilla.
Sprinkle the flour and salt over the batter and stir until it is completely combined. Fold in the chocolate chips, if using.
Layer half the brownie batter into a parchment lined 9×9 pan, then top with 20 Oreos.
Add the remaining brownie batter before breaking and pressing the remaining 5 Oreos into the top.
Bake at 350F for 30 minutes or until a toothpick inserted in the center comes out clean or with a few fudgy crumbs. Let the brownies cool completely before serving.

SAM’S TIP: Lining your pan with parchment makes for easy removal and cleanup. I do this with many of my brownies and bars, like my cosmic brownies.

Frequently Asked Questions

Can I use a 9×13 pan?

If you make this recipe as is in a 9×13 pan, your Oreo brownies will be very thin. I’d suggest doubling the recipe if you want your brownies to look like mine do in the pictures. Keep in mind your bake time will be different if you use a different pan (especially so if you use a glass pan, they just take much longer to cook!).

How do you get such clean cuts?

It’s very important to let your Oreo brownies cool completely before trying to cut them. Then, use your parchment sling (this is SO helpful!) to lift the brownies out of the pan. Press down with a sharp knife and clean the knife in between each cut–this may seem silly, but it really does make a difference! You can also run the knife under very hot water (then wipe it dry) between cuts, too.

Can I use any flavor Oreo?

Yes, as long as it pairs well with chocolate! I wouldn’t recommend using lemon Oreos to make Oreo brownies, but pretty much any other flavor out there (right now anyway) would taste great here. Have fun with it and let me know which flavors you try!
