Ingredients for Fudgy Oreo Brownies

This recipe relies on a few key players to achieve that signature fudgy texture and intense Oreo flavor.
Core Ingredients
- 1/2 cup chopped chocolate: Use good quality semi-sweet or dark chocolate for the best flavor. This melts into the batter, adding depth and richness.
- 1/2 cup sugar: You have options! Granulated white sugar is classic. Brown sugar (light or dark) will add more moisture and a slight caramel note. Coconut sugar works as an unrefined option, or use a cup-for-cup sugar-free baking substitute if preferred for your Fudgy Oreo Brownies.
- 1 cup plain yogurt: This is the secret to incredibly moist and Fudgy Oreo Brownies! Full-fat or low-fat works. For a dairy-free version, a plain, unsweetened non-dairy yogurt (like coconut or almond-based) is perfect.
- 3/4 cup all-purpose flour: Provides the structure for the brownies.
- 1/2 cup unsweetened cocoa powder: Choose a good quality Dutch-process cocoa for a darker color and richer chocolate flavor, or natural unsweetened cocoa powder will also work wonderfully.
- 1/2 teaspoon baking soda: Gives the brownies a little lift.
- 1/2 cup milk: Any kind will do – dairy (whole, 2%, skim) or non-dairy (almond, soy, oat). This helps to create the right batter consistency.
- 10 Oreo cookies, chopped: The star of the show! Roughly chop them; you’ll want some larger pieces for texture and some smaller bits to meld into the Fudgy Oreo Brownies. Reserve about 1/4 of the chopped Oreos for sprinkling on top before baking for that classic look.
Substitutions and Tips
- For an even richer chocolate flavor: Use dark cocoa powder and dark chocolate chunks. A teaspoon of instant espresso powder mixed with the dry ingredients will also intensify the chocolate notes beautifully.
- Flour Power: While all-purpose flour is standard, you can experiment with a gluten-free all-purpose blend if needed. Ensure it contains xanthan gum or add it according to the blend’s instructions.
- Spice it Up: A pinch of cinnamon or a tiny dash of cayenne pepper can add a lovely warmth and complexity to your Fudgy Oreo Brownies.
- Nutty Additions: If you love nuts in your brownies, feel free to fold in 1/2 cup of chopped walnuts or pecans along with the Oreos.
- Chef’s Insight: Don’t overmix the batter once the flour is added. Overmixing develops gluten, which can lead to tougher brownies. Mix until just combined for the fudgiest results.
- Oreo Variety: While classic Oreos are fantastic, feel free to experiment! Double Stuf Oreos will add extra creaminess, and Golden Oreos can provide a vanilla twist. Mint or peanut butter Oreos would also create delicious variations of Fudgy Oreo Brownies.
Best Type of Main Ingredient to Use
When it comes to making exceptional Fudgy Oreo Brownies, the quality of your chocolate and, of course, your Oreos, can make a delightful difference.
For the chopped chocolate, I recommend using a good quality baking chocolate bar that you chop yourself, or high-quality chocolate chips or chunks. Semi-sweet chocolate (around 50-60% cacao) offers a balanced sweetness that complements the Oreos beautifully. If you prefer a more intense, less sweet brownie, dark chocolate (70% cacao or higher) is an excellent choice. Avoid using candy bars, as they may contain stabilizers that don’t melt as well. The better the chocolate, the richer and more decadent your Fudgy Oreo Brownies will taste.
As for the Oreos, the classic, original Oreo cookie is hard to beat for that iconic cookies-and-cream flavor and texture. The balance of crisp chocolatey wafer and sweet cream filling is what makes these Fudgy Oreo Brownies so irresistible. However, as mentioned earlier, Double Stuf Oreos can lend an even creamier texture, while flavored Oreos like mint, peanut butter, or even red velvet can introduce exciting new dimensions to your brownies. If you opt for a flavored Oreo, consider how its taste profile will meld with the deep chocolate of the brownie base. The key is to ensure they are roughly chopped to get those delightful chunks distributed throughout.
Kitchen Tools You’ll Need
You don’t need a lot of fancy equipment to whip up a batch of these amazing Fudgy Oreo Brownies. Here are the essentials:
Must-Have Tools
- 8×8 inch square baking pan: This size is ideal for achieving thick, fudgy brownies. Glass, metal, or ceramic will work. If using a glass pan, you might need to reduce the oven temperature by 25°F (15°C).
- Mixing bowls: You’ll need at least one large bowl for combining the wet and dry ingredients, and a smaller one if you’re melting chocolate separately.
- Whisk: For thoroughly combining the wet ingredients and sugar.
- Rubber spatula or wooden spoon: Perfect for folding in the dry ingredients and the chopped Oreos without overmixing. Also great for scraping every last bit of batter from the bowl!
- Measuring cups and spoons: Accurate measurements are key in baking for consistent results.
- Knife and cutting board: For chopping the chocolate and Oreos.
Nice-to-Have Extras
- Parchment paper: Lining your baking pan with parchment paper, leaving an overhang on two sides, makes lifting the cooled Fudgy Oreo Brownies out of the pan a breeze and cleanup much easier.
- Electric hand mixer or stand mixer: While not strictly necessary (these brownies can easily be made by hand), a mixer can make combining the sugar and wet ingredients a bit quicker. Just be careful not to overmix once the flour is added.
- Wire cooling rack: Allows air to circulate around the brownies as they cool, preventing them from becoming soggy on the bottom.
How to Make Fudgy Oreo Brownies

Get ready to create the most irresistible Fudgy Oreo Brownies! Follow these simple steps.
Step 1: Prep Your Pan and Oven
Preheat your oven to 350°F (175°C). Grease and flour your 8×8 inch baking pan, or line it with parchment paper, leaving an overhang on two sides for easy removal. This little trick is a lifesaver!
Step 2: Melt the Chocolate (if needed)
If your chopped chocolate isn’t melting easily into warm ingredients, you can gently melt it. Either use a microwave in 20-second intervals, stirring in between, until smooth, or place the chocolate in a heatproof bowl set over a saucepan of simmering water (double boiler method), ensuring the bottom of the bowl doesn’t touch the water. Set aside to cool slightly. If your chopped chocolate is fine enough, it might melt directly when combined with the warm milk or yogurt mixture in the next steps.
Step 3: Combine Wet Ingredients
In a large mixing bowl, whisk together the sugar and plain yogurt until well combined. If your milk is cold, you might want to gently warm it (not hot, just lukewarm) and then stir in the chopped chocolate, allowing it to melt and combine smoothly. Alternatively, if you melted your chocolate separately, add it to the yogurt-sugar mixture. Then, stir in the milk and mix until everything is smooth and homogenous. The aroma should already be hinting at the delicious Fudgy Oreo Brownies to come!
Step 4: Add Dry Ingredients
In a separate medium bowl, whisk together the all-purpose flour, cocoa powder, and baking soda. This helps to distribute the leavening agent evenly and break up any lumps in the cocoa powder. Add the dry ingredients to the wet ingredients and mix with a rubber spatula or wooden spoon until just combined. Be careful not to overmix at this stage. A few streaks of flour are okay.
Step 5: Fold in the Oreos
Gently fold in about three-quarters of your chopped Oreo cookies into the brownie batter. You want to see those lovely chunks distributed throughout.
Step 6: Pour and Top
Pour the batter evenly into your prepared baking pan. Sprinkle the remaining chopped Oreos over the top of the batter. This not only looks great but adds an extra textural element to your Fudgy Oreo Brownies.
Step 7: Bake to Perfection
Bake for 25-30 minutes. The edges should look set, and a toothpick inserted into the center should come out with moist, fudgy crumbs, not wet batter. You’re looking for that perfect fudgy consistency. The smell in your kitchen right now should be absolutely heavenly!
Step 8: Cool Completely
This might be the hardest part! Let the Fudgy Oreo Brownies cool completely in the pan on a wire rack for at least 1 hour, or ideally 2-3 hours, before cutting. Cooling is crucial for fudgy brownies as it allows them to set properly, making them easier to cut into neat squares and achieving that desirable dense texture. Rushing this step can lead to messy, gooey brownies (though still delicious!).
Tips for Success
- Don’t Overbake! This is the golden rule for fudgy brownies. Keep an eye on them and test with a toothpick. Moist crumbs are what you want, not a completely clean toothpick (which would mean they are overdone and more cake-like). Start checking a few minutes before the stated bake time, as oven temperatures can vary.
- Use Room Temperature Ingredients: Especially the yogurt and milk. This helps them incorporate more easily and creates a smoother batter, leading to better textured Fudgy Oreo Brownies.
- Measure Flour Correctly: Spoon the flour into your measuring cup and then level it off with a straight edge. Scooping directly from the bag can pack the flour, resulting in too much flour and drier brownies.
- Quality Chocolate Matters: The flavor of your Fudgy Oreo Brownies will largely depend on the quality of the chocolate and cocoa powder you use. Splurge a little here if you can; it makes a noticeable difference.
- Patience with Cooling: Seriously, let them cool! Fudgy Oreo Brownies continue to set as they cool. Cutting them warm will be a messy affair, and they won’t have that signature dense, chewy bite. If you’re in a hurry, you can place the pan in the refrigerator after about 30 minutes of cooling at room temperature to speed things up.
How to Store Fudgy Oreo Brownies
While these Fudgy Oreo Brownies are often devoured quickly, here’s how to store them if you happen to have leftovers:
- Room Temperature: Once completely cooled, you can store the Fudgy Oreo Brownies in an airtight container at room temperature for up to 3 days. If your home is very warm or humid, consider refrigerating them sooner. They tend to get even fudgier the next day!
- In the Refrigerator: For longer storage, place the cut brownies in an airtight container or wrap the pan tightly with plastic wrap. They will keep well in the refrigerator for up to 5-7 days. Chilled Fudgy Oreo Brownies are incredibly dense and chewy – some people prefer them this way! You can enjoy them cold straight from the fridge or let them come to room temperature for about 15-20 minutes before serving. To reheat, a few seconds in the microwave (5-10 seconds) can bring back that just-baked warmth.
- Freezing Tips: Yes, you can freeze Fudgy Oreo Brownies! Once completely cooled and cut into squares, wrap each brownie individually in plastic wrap, then place them in a freezer-safe airtight container or a heavy-duty freezer bag. This double wrapping helps prevent freezer burn. They can be frozen for up to 3 months.
- Reheating from Frozen: Thaw the brownies at room temperature for a couple of hours or overnight in the refrigerator. If you like them warm, you can microwave an individual brownie for about 10-15 seconds after thawing, or until warmed through. They taste remarkably fresh!

Frequently Asked Questions (FAQs)
Can I make these Fudgy Oreo Brownies gluten-free?
Yes, you likely can! Substitute the all-purpose flour with a good quality 1:1 gluten-free baking flour blend that contains xanthan gum. The texture might be slightly different, but they should still be delicious.
What if I don’t have plain yogurt?
You can substitute sour cream in equal amounts for a similar tangy, moist result. In a pinch, buttermilk might work, though the texture could be slightly less dense. For dairy-free, stick to a plain, unsweetened non-dairy yogurt.
My brownies seem too gooey in the middle. What went wrong?
This usually means they were underbaked. Oven temperatures can vary, so it’s always best to rely on the toothpick test (moist crumbs, not wet batter). If they are very gooey, you might be able to return them to the oven for a few more minutes, loosely tented with foil to prevent the top from browning further, but ensure they are not completely cold before doing so. Remember, they will continue to set as they cool.
Can I use a different size pan for these Fudgy Oreo Brownies?
You can, but it will affect the baking time and thickness. A 9×9 inch pan will result in thinner brownies that bake faster (start checking around 20-25 minutes). A 9×13 inch pan would make very thin brownies, and you’d likely need to double the recipe for that size pan for a good thickness.
How do I get clean cuts on my Fudgy Oreo Brownies?
Ensure the brownies are completely cool – even chilled for 30 minutes in the fridge can help. Use a large, sharp knife. Wipe the knife clean with a damp paper towel between each cut. This prevents the fudgy interior from dragging and creating messy edges.
