Why I Always Love To Eat These Fudgy Oreo Brownies

I keep making these Fudgy Oreo Brownies because they hit that very specific texture I’m always craving! They’re dense, slightly chewy, and have that molten middle part that reminds me of a lava cake! Over the course of my cooking career, I’ve made a lot of brownie recipes, and I’ve noticed that the ones I actually crave again are never the cakey ones or the overly rich, chocolatey ones. These Fudgy Oreo Brownies ride that fine line in between a light and rich brownie. If I’m baking for myself or for others, this is the exact brownie recipe I’ll make because I know that these will satisfy every kind of preference for brownies!

Why Oreos Are One Of The Best Mix Ins

Oreos work so well here because they add contrast to the brownie without changing the texture of the actual brownie itself. You still get the slight crunch from the chocolate cookie and the cream melts into the brownie, creating these little pockets of oreo flavor! Unlike only using chocolate as a mix in for a brownie, you get distinct notes of Oreo throughout the brownie while using only chocolate will only yield a sweeter brownie rather than adding more flavor. The Oreos also help contrast against the rich fudgy texture of the brownie, which makes each bite not feel like biting into a bar of chocolate. I’ve tried using other cookies and mix ins before, but Oreos have always been the best for a balanced and delicious dessert!

How to Make Fudgy Oreo Brownies

Melt the butter in a microwave-safe bowl until fully liquid, or melt it in a pot, then let it cool slightly until warm to the touch.

Whisk the granulated sugar and brown sugar into the butter until the mixture looks smooth.

Melted butter combined with granulated sugar and light brown sugar in a mixing bowl before whisking to create a smooth brownie base.

Add the eggs and vanilla and whisk vigorously for 45 to 60 seconds until the batter thickens and turns shiny.

Brownie batter being vigorously whisked until thick, glossy, and smooth, a key step for achieving a shiny crackly top on fudgy Oreo brownies.

Whisk in the cocoa powder and salt until no dry pockets remain and the batter looks uniform.

Tips and Variations

For a softer center, pull the brownies slightly early once the edges are set and the middle still looks moist.

For a tighter crumb, fold the flour gently and stop mixing as soon as it disappears into the batter.

For cleaner slices of brownie like in the video, cool the brownies fully before cutting so the brownies has time to set.

To deepen the chocolate flavor, swap in dark cocoa powder while keeping the measurements the same.

Frequently Asked Questions

Why do I need to whisk the eggs so much?

Whisking the eggs thoroughly helps dissolve the sugars and creates the shiny batter that will ultimately yield that much sought after crispy top.

Can I use double-stuffed Oreos?

I tested this and noticed the filling melts more into the batter, which gives a slightly sweeter and creamier inside. Feel free to use if this is what you want!

How should I store these Fudgy Oreo Brownies?

Store them in an airtight container at room temperature for up to three days. I also like to freeze any extra and microwave for a minute whenever I’m craving a brownie!
