These rich, fudgy Oreo brownies are made with a handful of simple ingredients and can be whipped up in just one bowl! Make sure to check out the video on how I make them in my own kitchen!
My brownie obsession continues with today’s Oreo brownies, and I can’t overstate how grateful I am for all of you who have indulged me as I’ve now shared well over a dozen brownie recipes.
So far we’ve established the best brownie recipe, and made dozens of variations including ones that have been stuffed with peanut butter cups, loaded with cheesecake and cookie dough, and turned into snappy brownie brittle. It’s been a wild ride, guys.
And while not entirely brownie-related, I have to mention that another journey I really appreciate you guys accompanying me on is my one through video. It’s been a bit, but I finally uploaded a new video to YouTube (for this Oreo Brownie recipe, you can check it out just above the recipe below).
I’m hoping that eventually the process gets less overwhelming, but learning video is like learning photography all over again and has resulted in many headaches and late nights.
I’ve been filming every week to the point where I have a backlog because the editing is just… exhausting! I can’t even begin to justify the number of Oreo Brownies I downed while piecing together this most recent video.
But, setting all that video-related stress aside, let’s talk Oreo Brownies.
I used my easy brownie recipe as the base for this recipe. As many of you know, that recipe took dozens of trials to perfect and I’m absolutely in love with its rich chocolaty-ness, the chewy fudginess, and the fact that it requires just one bowl to make! It was the perfect brownie batter for mixing in a pile of broken Oreo pieces.
Tips for Making Oreo Brownies
- I used classic Oreo cookies, but feel free to substitute your favorite variety (there are so many to choose from now!). Do they still make cookie dough Oreos? I definitely would want to try that next.
- To break your Oreos into pieces, I recommend placing them in a large Ziploc bag then using a rolling pin or mallet to break into pieces. Don’t smash them into crumbs, it’s nice to have real Oreo pieces to bite into! (Also, if you watch my video below, I included some bloopers at the end including one where I totally messed up explaining that part 🤦🏼♀️).
- You can substitute 6 oz of chopped chocolate for the semisweet chocolate chips if you don’t have the chips on hand. Semisweet or Dark chocolate bars work, but I don’t recommend using unsweetened as it will make your Oreo brownies too bitter.
- The instant coffee is totally optional! Rather than make your brownies taste like coffee, it enhances the cocoa flavor and gives you a richer Oreo brownie. If you don’t have any on hand, you can of course leave it out, though!
How to Make Oreo Brownies
- 12 Tablespoons unsalted butter cut into Tbsp-sized pieces 170g
- 1/2 cup semisweet chocolate chips 100g
- 1/2 cup natural cocoa powder 50g
- 1/2 teaspoon instant coffee grounds optional
- 3/4 cup sugar 150g
- 3/4 cup brown sugar packed 150g
- 2 large eggs + 1 egg yolk
- 1 teaspoon vanilla extract
- 1/2 teaspoon salt
- 1 cup all-purpose flour 122g
- 1/3 cup mini chocolate chips 70g
- 20 Oreo Cookies divided
Preheat oven to 350F and line a 9x9 baking pan with parchment paper*
Combine butter and 1/2 cup (100g) semisweet chocolate chips in a large, microwave-safe bowl.
Microwave for 30 seconds. Stir well, microwave for another 15 seconds and then stir well again. Repeat for 15 seconds until chocolate and butter are completely melted and well-combined.
Add cocoa powder and instant coffee (if using), stir well.
Add sugars, stir until completely combined.
Add eggs, one at a time. After each addition, stir well, and then stir another 30 seconds (the better you stir your batter, the cracklier your brownie tops will be).
Stir in vanilla extract.
Sprinkle salt over batter and add flour, stir very well, until completely combined.
Place 15 of your Oreos in a large Ziploc bag and use a rolling pin or mallet to smack until broken into pieces (don't crush into fine crumbs, you want decent sized pieces to bite into!).
Add broken cookie pieces and mini chocolate chips and stir into batter.
Spread batter into prepared 9x9 pan.
Break remaining 5 Oreo cookies into pieces and press gently into the surface of the brownie batter.
Bake on 350F (175C) for 30-35 minutes if using 9x9 pan (toothpick inserted in center should be just slightly fudgy, but not wet with batter).
Allow to cool before cutting and serving.
*Alternatively you may grease and flour your pan -- the parchment paper is a little wiggly when you're trying to spread your batter into it, but I prefer it for ease of cleanup.
