A simple, one-bowl recipe, these brownies will be prepped and out the oven within 1 hour. Allow to cool completely before slicing into squares. You can store these brownies in an airtight container at room temperature or in the fridge for up to a week – perfect for when a brownie/Oreo craving kicks in. 😉

Fudgy Oreo Brownies

Deliciously thick and fudgy brownies that are chocolatey rich, and loaded with Oreo cookies!
Prep Time 15 minutes
Cook Time 35 minutes
Total Time 50 minutes
Yields 9 big bars, or 16 small bars


  • 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
