Brownie ingredients

You’ll only need 7 simple ingredients for this Oreo brownie recipe. (I’m making it harder and harder for you to say no to it, right?!)

Ingredient amounts are listed in the recipe card below, but right now, here’s what you need to know:

Butter: This recipe calls for unsalted, but if you want to use salted butter, just reduce the added salt to ¼ teaspoon. 

How to make Oreo brownies

Pull out your electric mixer - you’ll need it for that shiny brownie crust we all love - and let’s make some Oreo brownies!

Step two: Cut your butter into cubes (to help it melt evenly) and combine it with chopped chocolate in a medium, microwave-safe bowl. Microwave for 30-second increments, stirring in between, until smoothly melted. 

Step three: Using a stand mixer with the wire whip attachment, or an electric hand mixer with a large bowl, beat together granulated sugar and eggs on medium-high speed for several minutes. The mixture should be thicker and much paler in color, and should “ribbon” down from the beater when lifted, like you can see in the photo below. 

Step four: With your mixer on low speed, pour in the melted butter and chocolate. Continue to mix until smooth. Sprinkle the dry ingredients (flour and salt) over the wet ingredients and mix in on the lowest speed just until no streaks of flour remain. Don’t overmix!

Step five: Transfer half of the batter to your prepared baking pan, using an offset spatula to spread it to all corners in an even layer. Place whole Oreos in a 4x4 pattern on top of the batter, pressing them in gently. Cover the Oreos with the remaining brownie batter, spreading it out in a smooth layer on top. Finally, sprinkle the top with chopped Oreo pieces. 

Step six: Bake these Oreo brownies at 350ºF for 25-30 minutes, just long enough for a toothpick inserted into the center of the pan to come out with only a few moist crumbs. Transfer the pan to a wire rack and let the brownies cool completely before removing and slicing. 

Tips for making perfect brownies - with Oreos!

• Measure your ingredients by weight if possible. At the very least, make sure you measure your flour accurately by spooning it into the measuring cup and then leveling it off with a knife. Too much flour will make your brownies more cakey than fudgy.
• To get that perfectly crinkly top on your brownies, always whip the eggs and sugar together until the mixture falls from the beaters in a ribbon-like pattern.
• To make sure your brownies stay soft and chewy, don’t overmix the batter once you’ve added your flour.
• Use a good-quality metal baking pan with squared-off edges. 
• Don’t overbake. When in doubt, always err on the side of under-baking if you want extra fudgy brownies. 

Recipe variations

• Like the sound of peanut butter Oreo brownies? What about mint Oreo brownies? You can make both with this recipe! Just switch up the type of Oreo cookies you use.
• Add chocolate chips, white chocolate chips, or even peanut butter chips to the batter for extra flavor and sweetness.
• Top your brownies with frosting or chocolate ganache, and then sprinkle the chopped Oreos on top of that. For a basic chocolate ganache, you can warm ½ cup of heavy cream until steaming, and then stir in 5 ounces of chopped chocolate.

Storing and freezing brownies

These Oreo-stuffed brownies can be kept in an airtight container at room temperature for 1 week.
