Fudgy chewy Oreo brownies are the perfect chocolaty dessert you will love making as much as you do eating. This one bowl brownie recipe is a guaranteed favorite!
Why you'll love it
These Oreo brownies are decadent. Fudgy, deeply chocolaty (perfect for chocolate lovers), and studded with Oreos in every bite! Just like these peanut butter brownies and these fudge brownies, they are guaranteed to satisfy every craving you could have. The crunchy and slightly bitter cocoa flavor of the Oreos provides a delightful contrast to the soft and gooey richness of the brownie base. This combination adds depth and complexity to the dessert, making it a treat that's both comforting and exciting.
They're also a cinch to make! You can take your favorite brownie recipe - this one is based off my perfected homemade brownies and add chopped Oreos and you are on your way to the best dessert ever!
- You need simple ingredients that are kitchen staples, so chances are you can whip these fudgy brownies up any time
- This is easily a one bowl recipe requiring very little cleanup when you are done
- It's perfect in an 8x8 pan or you can double it for a 9x13 pan
- It is better than your box mix brownies and just as easy to make
Key ingredients
These fudgy Oreo brownies are so great because of the simplicity of ingredients used. Basically all the ingredients are pantry staples, which makes them incredibly convenient to make. Of course, since the recipe is such a simple one, the quality of the ingredients you use matters. You can find the full list of ingredients in the recipe card below.
- Cocoa powder - Both natural unsweetened cocoa powder and Dutch-process cocoa powder work for these brownies. You can use them interchangeably. For the best flavor, you should add it to the butter as it is melting. This will "bloom" the flavor and make it more pronounced, but it is optional.
- Chocolate - Semi-sweet, dark chocolate, or a combination of both work best in this recipe. It I recommend reaching for a high quality brand of bar chocolate over anything else.
- Sugar - To up the chewiness of these brownies, we increase the amount of brown sugar and use just a touch of granulated. You can use all of just one type, if desired.
- Oreos - Although I have listed a number of Oreos in the actual recipe, I say you should measure that with your heart. There is no such thing as too many Oreos in these brownies, and you can of course use less (or more), if needed!
- Oil - This recipe uses vegetable oil (you can use any neutral flavored oil). This helps keep these brownies moist and tender. Do not use any type of olive oil or flavored oil because it will affect the final flavor.
How to make
These decadent brownies can easily be made in one bowl, which is my favorite part of the recipe. In fact, the only reason I used more than one bowl in the recipe is was for the photos.
- Line your square pan with parchment paper, letting some overhang for easy removal later.
- Add your butter, brown sugar, and chocolate to a saucepan and heat on medium.
- Stir consistently to melt chocolate and butter together with the sugar, Remove from heat and allow to cool for at least five minutes. You can continue to stir to speed up the process
- Add the eggs and vanilla then beat well for at least two minutes.
- Gently stir in the flour, cocoa powder, and salt just until there are no streaks of your dry ingredients left.
- Fold in the crushed Oreos, then pour the brownie batter in your prepared pan. Sprinkle the top of the brownie batter with more Oreos
- Bake until there are just a few moist crumbs clinging to a toothpick when inserted in the center of the brownies and wait about 5 10 minutes before transferring the brownies to a wire rack to cool completely.
Best baking pan to use
The baking pan you use when baking these delicious Oreo brownies (or any brownie recipe) is very important because it will impact the bake time and final texture of your brownies.
- A reflective aluminum baking pan works the best. It heats up quickly and retains even heat throughout the baking process. Lighter aluminum baking pans are better than darker baking pans because the darker pans will conduct heat too fast and may result in overbaked brownies.
- Although ceramic or glass pan is nice to look at and watch the brownies bake from all sides, it takes longer to conduct heat. This can result in edges that are overdone and centers that are underdone.
Expert brownie baking tips
The most important way to ensure you get the best brownies is to make sure you are correctly measuring your ingredients, particularly the flour. You should fluff up the flour and then spoon it into your measuring cup then sweep of the excess. If you want to make sure you get consistent results, you can convert the recipe to metric and use a kitchen scale.
Make sure your ingredients are at room temperature. If you need to quickly bring eggs to room temperature, you can leave them in a bowl of warm water for five minutes before using. You can soften butter quickly using a few different methods.
For that classic brownie glossy, crackly top, you need to really beat the eggs and sugar together very well. It also helps to add the sugar to the hot butter before adding the eggs.
You can bloom the cocoa powder by adding it to the butter and chocolate as it melts. It is not a necessary step and we don't do it in this recipe, but it is worth experimenting.
If you forget to add the chocolate to the butter while melting, you can quickly do it in the microwave. You can also melt the butter with the chocolate in the microwave too. Add it to a microwave-safe bowl and heat for 30-second increments, stirring well after every 30 seconds. Stop the process when most of the chocolate is melted and stir to help melt the remaining chocolate using the residual heat.
Do not overmix the batter when you add in the dry ingredients! Overmixing is how you end up with cakey brownies. Instead, gently stir just until there are no streaks of flour left.
Don't forget to line the baking pan with parchment paper to make it easier to take out the bars once they've cooled enough to remove from the pan.
Use a light-colored metal pan. Dark pans encourage fast browning which can leave you with burnt brownies and glass pans do not conduct heat as well leaving you with brownies that longer to bake and are a lot more dense.
Variations
There are so many ways to change up your Oreo brownies to make them more fun and interesting!
- You can use different flavored Oreos as a quick and easy way to experiment with different flavor profiles.
- Mix in dark chocolate chips, white chocolate chips, peanut butter chips, chopped candies, or nuts into the brownie batter.
- Top them with a chocolate chip cookie recipe to make a type of brookie. Or you can top them with a cookie dough frosting!
- Make these with brown butter for a delicious nutty note.
- Top your brownies with a scoop of vanilla ice cream, drizzle with salted caramel sauce, or peanut butter sauce
Recipe FAQs
Yes, you can freeze your Oreo brownies. Tightly wrap your brownies, then place them in an airtight container. Freeze in the back of your freezer for up to a month. When you are ready to eat them, thaw them in the refrigerator first before bringing them to room temperature.
Oreos are naturally vegan, making these brownies very easy to convert to an all-vegan recipe. Simply replace the unsalted butter with a vegan butter/margarine. You can replace the eggs using this:
¼ cup ground flax seeds mixed with ½ cup water. Leave to rest for 5 minutes.
