Fudgey Oreo Brownies

The BEST Oreo brownies have a brownie base, stuffed with Oreos, frosted with dark chocolate ganache and topped with more Oreos!

How To Make Oreo Fudge Brownies

Let’s start with the worst part about make these brownies…waiting. The best brownies are slightly under-baked & allowed to cool before devouring. These brownies have that step but they also require to be refrigerated for at least a couple hours after adding the ganache so it makes it a tincy wincy bit harder.

Other than that, the recipe is pretty basic. You always want to beat the eggs with the sugar first to get that crackly top on the brownies. Then you add the melted butter & chocolate. Last but not least you fold in your dry ingredients JUST UNTIL COMBINED. You can even still have a few streaks of flour here and there, just don’t over-mix. Layer with Oreos. Bake. Cool. Top with ganache & more Oreos. Refrigerate. Slice. Serve. End of story.

What you’ll need:

  • Butter: the butter gets melted so it doesn’t matter if it’s cold but it is quicker if the butter is already soft. I use unsalted but if you only have salted you can use that too and just omit the salt in the recipe.
  • Chocolate: you can use milk chocolate, semi-sweet chocolate or dark chocolate. I prefer semi-sweet for this recipe and I’m partial to Ghirardelli or Guittard Chocolate.
  • Eggs: always use large, room temperature eggs unless specified otherwise.
  • Sugar: I use both brown sugar and granulated sugar in this recipe for stability, flavor and ultra gooeyness. 
  • Flour: I always use all-purpose flour unless otherwise specified and I HIGHLY recommend using a digital kitchen scale to measure all your ingredients, especially the flour. 
  • Cocoa Powder: the better quality your cocoa powder is, the better your brownies will taste! Make sure it’s UNSWEETENED cocoa powder. My favorite is Ghirardelli Dutch Process, King Arthur Dutch Process or Rodelle Dutch Process Cocoa Powder. It doesn’t have to be dutch process for the recipe but I prefer the flavor and color of dp cocoa.
  • Salt: salt brings out the flavor in all baked goods.

How to store Oreo fudge brownies

If the brownies aren’t sliced, you can just cover the pan with foil and leave it out on the counter overnight. If the brownies are sliced, I recommend placing them in an airtight container and leaving them on the counter for a couple days.

If it’s any longer, you can refrigerate them for up to a week or freeze them for 2-3 months. If you freeze them, place the airtight container in a freezer bag and squeeze all the excess air out. Leave the brownies at room temperature overnight to thaw.

It really is quite simple. & well worth every dollar, second & calorie. If you make these, I’d LOVE to see so please tag me @baranbakery on instagram & let me know what you think. They’re one of my favs & I’m sure they will be yours too!

Fudgey Oreo Brownies Recipe

Fudgey brownies with an oreo center, chocolate ganache topping, and topped with more oreos!

Prep Time 20 minutes
Cook Time 35 minutes
Additional Time 2 hours
Total Time 2 hours 55 minutes



  • 3/4 cup (170g) unsalted butter
  • 6 ounces dark chocolate chips or bar
  • 1 cup (120g) all-purpose flour, spooned and leveled
  • 1/4 cup (25g) Dutch-process cocoa powder, spooned and leveled
  • 1/2 tsp fine sea salt
  • 4 large eggs, room temperature
  • 1 cup (200g) granulated sugar
  • 1/2 cup (95g) light brown sugar, lightly packed
  • 1 tsp vanilla extract
  • 12-16 oreos


  • 1 1/2 cup dark chocolate
  • 1/2 cup heavy cream
  • 4-8 oreos


  1. Preheat the oven to 325F/163C convection (300F/149C conventional) and grease and line an 8"x8" pan.
  2. Melt the butter with chocolate together and set aside. Whisk together the flour, salt and cocoa powder and set aside.
  3. Whisk together the eggs and sugars just until they're combined (still a little gloopy). Add in the chocolate/butter mixture and vanilla and mix lightly (still a little gloopy).
  4. Fold in the dry ingredients, just until the flour is mostly incorporated.
  5. Spread half of the batter on the bottom of the pan. Layer whole Oreos on top and spread the rest of the batter over the Oreos.
  6. Bake for about 35-40 minutes. Allow the brownies to cool in the pan for about 30 minutes, then refrigerate them while making the ganache.
  7. Place your chocolate in a heat proof bowl. Heat the heavy cream in a medium sauce pan and remove just before boiling. Pour over the chocolate and stir until smooth.
  8. Pour over the brownies (while they are still in the pan). Separate the Oreos in half and layer on top of the ganache.
  9. Refrigerate the brownies for at least 2 hours before removing from the pan and slicing (best if refrigerated overnight).


You can use a different pan size such as 9″x6″ that has a similar square inch.

If you are having difficulty slicing (Oreos sliding through ganache) you have to refrigerate longer.
