Deliciously thick and fudgy brownies that are chocolatey rich, and loaded with Oreo cookies!
  • 1 and 1/4 sticks unsalted butter 140g
  • 1 and 1/2 cups granulated sugar 300g
  • 3/4 cup cocoa powder 75g
  • 1/4 teaspoon salt
  • 2 teaspoons vanilla extract
  • 2 large eggs cold
  • 1/2 cup plain/all-purpose flour 60g
  • 1/2 cup chocolate chips 90g
  • 16 Oreos whole
  • Oreos chopped
  1. Preheat the oven to 180C/350F/Gas 4. Line an 8x8-inch square baking pan with foil or parchment paper, and set aside.

  2. Place the butter, sugar, cocoa powder, and salt into a microwave-safe bowl, and microwave in 30 second intervals, stirring after each one, until the butter is melted and the mixture feels very warm to the touch.

  3. Mix in the eggs, one at a time. Fold in the flour until fully combined. Fold in the chocolate chips (they will melt into the batter, but it's fine! It helps produce a shiny top). Stir in the vanilla extract.

  4. Pour half of the batter into the prepared pan, and spread out evenly. Place the whole Oreos evenly over the batter, and top with the remaining batter. Top with the broken Oreos.

  5. Bake for 30 - 35 minutes, or until a toothpick inserted into the centre comes out almost clean with a few moist crumbs. Allow to cool completely in the pan on a wire rack before cutting into squares.

Brownies stay fresh, stored in an airtight container, at room temperature or in the fridge for up to 1 week. They also freeze well for up to 3 months. Thaw overnight in the fridge before serving.

    Heaven in edible form. There’s an alternate name for you, just in case you ever need one. But for real, I cannot get over how good these look! NEED to try them soon!

    These look incredible! Brownies are such a delicious and decadent treat – the addition of Oreos would only enhance their wonderful chocolate-y taste!

    How did I almost miss this delectable treat? Because, honestly, the only thing better than brownies is brownies STUFFED with oreos!! These brownies look perfectly moist, Marsha! Loving that crispy top too. Now I’ll just be dreaming about a nice warm batch of these all day. Wishing you and the fam an amazing weekend ahead. Hugs! xoxo

    What type of cocoa powder did you use?

      I use Dr. Oetker Fine Dark Cocoa Powder which I believe is Dutch-processed. I also love Green and Black’s!

        Thank you! I’ll check out those brands. I made these tonight using regular cocoa powder not Dutch, so I’ll see how they turned out in the morning. I know sometimes using one type of cocoa versus the other can make a difference in the final product. They smelled great though!!

          It certainly can, but I always stick to this cocoa powder for whatever I’m making 🙂 Enjoy!

    Love these brownies so easy to make and the Oreos take them to another level. I used cheesecake Oreos crushed on top of the brownies does this matter?

    Have you tried making these in a 9×13 pan? I’m going to try them for a potluck so will need a larger serving.

    Two questions: am I supposed to soften the butter first before I combine it with the sugar, cocoa, and salt into the microwave? I’m accustomed to baking with semi sweet chips. I didn’t see semi sweet in the ingredients. Am I supposed to use regular chip?

    • Reply

      No need to soften the butter, just cut it up into cubes so it melts faster. You may use any chips you like! 🙂

    I’ve made these for years. Every time I share them people name them disgusting brownies because they tell other people they are no good so they can eat them all themselves. THEY ARE THAT GOOD! Thanks for sharing this great recipe

    Isn’t it too much sugar a cup and a half? As the brownies are very sweet with the Oreos and chocolate chips?

    • Reply
      16th February 2018 at 5:18 pm

      I don’t think these brownies are overly sweet at all, despite the add-ins! The amount of sugar in these brownies is just right and helps towards making them dense and fudgy 🙂
