These fudgy Oreo brownies are a chocolate lovers dream! They’re super simple to make and result in delicious brownies with plenty of Oreo cookies!

There’s no better packaged cookie than an Oreo. And though I love eating them right from the package, I also LOVE baking with them!! From cookies & cream cookies to Oreo dirt cake, I just can’t get enough!
When I used a package of Oreos to bring a box of brownie mix to the next level, I knew I’d have to share these with you!!
Ingredients Needed (Amounts in Recipe Card Below)
- Brownie Mix: You can use a box of fudge brownies, milk chocolate or dark chocolate.
- Ingredients Needed Prepare Box Mix: Most box mixes call for eggs, vegetable oil and water.
- White Chocolate Chips: Optional, but really help give the cookies & cream flavor! You could also use milk, semi-sweet, dark chocolate chips, chocolate chunks….or even peanut butter chips!
- Oreo Cookies: The star of the show! You’ll need a generous amount of Oreo cookies. You can use classic Oreo cookies or experiment with different Oreo flavors for a unique twist
- Milk: Any type of milk will work fine.
How to Make Oreo Brownies
Step 1: Preheat Your Oven
Preheat your oven to 350°F and grease a baking pan. You can also line with parchment paper for easy removal.
Step 2: Prepare the Brownie Batter
In a large bowl, combine the box brownie mix and other ingredients as listed on the package instructions. Once the batter is smooth, stir in the white chocolate chips.
Step 3: Layer it Up
Spread about half of the batter into the prepared pan. Next, you’ll dunk the whole Oreos one-by-one into a bowl of milk and arrange them over the brownie batter in the pan.
If you want to keep the cookies super crunchy, you can skip the milk part. I like to make four rows of four cookies.
Spread the remaining batter over the cookies.
Step 4: Pour and Bake
Sprinkle a couple crushed Oreos on top of the brownies, pressing them gently into the batter. Bake in the preheated oven for about 35-38 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Step 5: Cool and Enjoy
Let your Oreo brownies cool in the pan for a while before transferring them to a wire rack to cool completely. Once cooled, slice them into squares and enjoy!
How to Cut Brownies
There are a few tricks to getting a clean cut on a pan of brownies. For best results, let them cool completely. Remove the brownies from the pan and place them on a cutting board.
Using a plastic disposable knife is a probably the best way to cut brownies (seems strange, but it really works great)!! You can also use a large chef’s knife and clean it between cuts.
How to Serve Oreo Brownies
These are truly delicious on their own, but they’re also delicious topped with a scoop of vanilla ice cream, hot fudge and chopped Oreos for a decadent sundae!
What Flavors of Oreos Can I Use?
Ohhh SO many different options for these delicious Oreo brownies!! A few of my favorites include the original, peanut butter, mint, cookie dough and double chocolate. I’d recommend steering clear of any fruit flavored Oreos as they won’t mesh well with the brownies.
Want an Extra Fudgy Brownie?!
Grab a jar of hot fudge and add a few spoonfuls over the Oreos before you put the rest of the batter in the pan. You’ll have little pockets of fudge throughout that bring a rich chocolate flavor to these decadent brownies!
How to Store Leftover Oreo Brownies
You can keep these in the baking pan covered tightly with plastic wrap or in an airtight container at room temperature for 3-5 days. You can also them in the freezer for up to 2 months.
