Oreo brownies bring the perfect combination of chewy brownies with the extra crunch of Oreo cookies. These rich chocolate brownies with Oreos are easy to make and aim to please! Once you’ve had these fudgy Oreo brownies, with extra chocolate, you won’t want to go back to plain brownies ever again!
If you are an Oreo fan, you no doubt love any new way to enjoy your favourite cookies! And these brownies sure do tick all the boxes. Although, while we are talking Oreo desserts, don’t forget to check out my no-bake Oreo cheesecake bars too. Oh my… they are amazing!
Okay, back to brownies! Let’s see how to make these decadent, fudgy brownies!
- Melted butter
- Plain flour (The recipe uses 1 cup of flour, but if you want your brownies even fudgier… drop it down to half or 3/4 a cup instead)
- White granulated sugar
- Vanilla essence
- Baking powder
- Milk chocolate chips
- Oreos (You’ll need at least 20 cookies… or more if you want!)

How To Make Oreo Brownies
- Pre-heat oven to 180 degrees Celsius. (Find temperature conversions). Line a brownie pan with baking paper and set aside.
- Melt butter then in a large bowl, mix in flour, sugar, cocoa, baking soda, salt, eggs, chocolate chips and vanilla and combine.
- Pour half of the brownie batter into the pan. Place Oreos on top of brownie mix and press down slightly.
- Pour the remaining mixture over the Oreos. Top with broken Oreo pieces… as many as you would like.
- Bake for approximately 25 to 30 minutes, or until the centre is no longer runny.
- Cut into squares and serve.
Tips & Tricks
- For moist, fudgy brownies, reduce the amount of flour you use to half a cup or 3/4 a cup instead of using a full cup. Alternatively, if you want more of a chocolate cake density, use 1 and a half cups of flour instead.
- To confirm if your brownies are cooked enough, the centre should no longer be runny. You can tell this by whether it jiggles if you shake the tray.
- If your brownies are still a little, soft this is okay, as you don’t want to overcook them. But you also don’t want chocolate sauce!
- If the centre isn’t moving when you shake them, test with a toothpick or knife to see if it comes out mostly clean.
The chocolate chips aren’t essential for this recipe. It still tastes great without them. We’ve had to omit them once or twice when realising we had none in the house. Oops! But they do give it that extra fudgy brownie taste.
- Instead of milk chocolate, try dark chocolate chips or white chocolate chips. Both are amazing options!
- Swap out original Oreos for strawberry or double chocolate flavour.
- Or mix in walnuts or macadamia nuts for some extra crunchiness!
How To Store Oreo Brownies
To store your brownies, keep them in an airtight container on the bench for up to 3 days, or keep them in the refrigerator for up to one week.
If you wish to freezer the brownies, they will freeze for up to 2 months. Simply defrost and enjoy!
In fact, they taste great microwaved from frozen with a dollop of ice cream on top for a quick midweek dessert idea!
