Ingredients

  • Oreo Cookies: Add a crunchy texture and an iconic cookies-and-cream flavor.

  • Eggs: You’ll use whole eggs plus a yolk for added chewiness.
  • Vanilla Extract: Enhances the chocolate flavor and adds depth to the overall taste profile.
  • All-Purpose Flour: Provides structure to the brownies.
  • Unsweetened Cocoa Powder: Delivers intense chocolate flavor without added sugar.

How to Make Oreo Brownies

Whether served warm and gooey or cooled to perfection, these brownies never fail to disappear at gatherings.

Here’s how to make them:

1. PREHEAT the oven to 350°F and line a 9×13-inch baking pan with parchment paper.

2. MELT the butter and half of the chocolate in a microwave-safe bowl until smooth. Add the cocoa powder and whisk until lump-free.

3. BEAT the sugars with the eggs, yolks, and vanilla until thick and pale using an electric mixer on medium speed.

4. BLEND in the melted chocolate and butter on low speed while the mixer is running.

5. ADD the flour and salt, mixing gently by hand. Fold in the remaining chocolate just until no streaks of flour are visible.

6. LAYER half the brownie batter into the prepared pan, followed by a layer of crushed cookies, more brownie batter, and the rest of the brownie batter.

7. BAKE for 35-40 minutes until set around the edges but still slightly gooey in the center.

8. COOL the brownies completely, then lift them out of the pan using the parchment overhang. Slice into squares and enjoy!

Tips For the Best Oreo Brownies

This decadent treat is basically what would happen if a brownie and an Oreo had a very delicious baby.

But before you get mixing, here are a few tips to keep in mind.

  • Use room-temperature ingredients. Get the chilled ingredients out of the fridge early. It makes mixing easier.
  • How to mix: Beat the eggs with an electric mixer until they are nice and thick. Stir in the flour by hand with a spatula to avoid overmixing.
  • Combine slowly. Add the warm chocolate to the eggs slowly, with the mixer running. If you add hot chocolate all at once, you might scramble the eggs.
  • Ultra fudgy brownie. Underbake the brownies slightly for an ultra-fudgy texture. Let them cool completely before cutting.
  • The best cutting technique. Use a sharp knife, wipe it clean between cuts, and chill the brownies before slicing for more precision.
  • Creative variations. Experiment with Oreo flavors like mint, birthday cake, or peanut butter. Or add white chocolate chips or drizzle with caramel for extra indulgence.

How to Store

Fair warning: these disappear FAST! Even with a double batch, they won’t last long.

But if you happen to have any left, here’s how to store them:

To Store: Place the cooled brownies in an airtight container, separating layers with parchment paper. Keep them at room temperature for up to 5 days or in the fridge for up to a week. 

To Freeze: Wrap individual brownies tightly in plastic wrap. Store them in a freezer-safe container or zip-top bag for up to 3 months. Thaw in the fridge overnight.

Note: Oreo brownies are best enjoyed at room temperature. So be sure to set chilled leftovers out at room temperature to warm slightly.

Rich, fudgy Oreo brownies packed with chocolate and layered with crunchy cookies are a decadent treat that’s easy to make and perfect for chocolate lovers!

Ingredients

  • 1 cup unsalted butter, melted

  • 8 ounces semisweet or dark chocolate chips, divided

  • 3/4 cup unsweetened cocoa powder

  • 1 1/2 cups granulated sugar

  • 1/2 cup light brown sugar, packed

  • 3 large eggs + 1 egg yolk, room temperature

  • 1 teaspoon vanilla extract

  • 1 cup all-purpose flour

  • 1/2 teaspoon salt

  • 30 Oreo cookies, divided

Instructions

  • Preheat the oven to 350°Fahrenheit (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides. Lightly grease the parchment with cooking spray and set aside.
  • In a microwave-safe bowl, melt the butter and 4 ounces of chocolate in 30-second intervals until smooth. Add the cocoa powder and whisk well until lump-free.
  • In a separate large bowl, beat the granulated and brown sugars with the eggs, yolk, and vanilla until thick and pale. Use an electric mixer on medium speed.
  • Reduce the speed to low and blend in the melted chocolate and butter slowly while the mixer is running.
  • Add the flour and salt and mix gently by hand until about halfway combined. Add the remaining chocolate and mix just until no streaks of flour are visible.
  • Pour half the brownie batter into the prepared baking pan, spreading it evenly. Crumble half of the Oreos over the brownie batter, spacing them evenly across the surface. Spoon the remaining brownie batter over the crushed cookies, carefully spreading it with a spatula to cover the cookies completely.
  • Top the brownie batter with more crushed Oreos or nestle whole Oreos evenly over the surface.
  • Bake for 35-40 minutes until set around the edges but still slightly gooey in the center. A toothpick inserted in the center should come out with a few moist crumbs, but not entirely clean.
  • Allow the brownies to cool completely. Then, lift them out using the parchment overhang and slice into squares. Enjoy!

Notes

  • Use high-quality unsweetened cocoa powder and chocolate for the richest flavor.
  • Beat the eggs with an electric mixer until they are nice and thick. Stir in the flour by hand with a spatula to avoid overmixing.
