Ingredient Notes

• Oreos: Don't forget to add extra Oreo crumbs and pieces on top!
• Chocolate: Use a high quality semi-sweet chocolate for a unique flavor profile of a rich, dark cocoa brownie paired with semi-sweet chocolate. Alternatively, you can use milk chocolate, or even dark chocolate chips.
• Cocoa Powder: I used a combination of dutch process and black cocoa powder for a more rich & intense chocolate flavor.
• Flour: Use high quality unbleached all-purpose flour best results.
• Unsalted Butter: Use high quality European-style butter for best overall flavor.
• Sugars: This recipe calls for a combination of granulated and brown sugar to achieve the right amount of fudgyness and chewy texture.
• Eggs: Bring your egg to room temperature quickly by placing it in a bowl of warm water for 10 minutes.
• Vanilla: Add a high quality vanilla extract for optimal flavor.

Step by Step Instructions

Here are step by step photos and instructions on how to make this decadent Oreo brownie recipe! For the full ingredient list and method, see the recipe card at the end of this post.

STEP 1: Melt the chocolate. In a small bowl, add the bittersweet chocolate and butter. Place over a small saucepan of simmering water, and stir often until fully melted. Remove from the double boiler and allow to cool for a few minutes.

STEP 2: Cream the butter and sugars. Meanwhile, in a large mixing bowl, add the sugars, eggs, and vanilla. Using an electric mixer, beat the wet ingredients on high speed for about 5-6 minutes until the mixture has doubled in size.

STEP 3: Mix in the chocolate. While mixing on low speed, slowly pour in the chocolate butter mixture to the egg mixture.

STEP 4: Add dry ingredients. Once it is fully combined, add the flour, cocoa powders, and salt, and fold until fully combined.

STEP 5: Assemble. Pour half of the brownie batter into the prepared 9-inch pan, then top with whole Oreos and pieces to fill in the gaps. Add the remaining batter and smooth out the top with an offset spatula. Add more Oreo pieces to the top of the brownie batter, if desired.

STEP 6: Bake. Bake the brownies for about 32-35 minutes, until a toothpick comes out mostly clean. Allow them to cool completely in the baking pan before removing and cutting.

Expert Baking Tips

• Use a high-quality bittersweet chocolate. I recommend Valrhona or Guittard. 
• Substitute for black cocoa powder. If you do not have black cocoa powder on hand, you can use a total of 84g (1 cup) dutch process cocoa powder instead. 
• How to cut brownies: To get clean cut squares, use a sharp knife and run it under hot water (and wipe clean) before each cut.

All of the recipes on this blog are carefully developed with gram measurements so you can easily recreate them in your own kitchen with success. Volume measurements are extremely inaccurate and leave room for significant errors. Not all measuring cups are made equally, so your one cup of flour will be different from my one cup of flour. By providing precise measurements in grams (aside from minor ingredients, which are given in tsp/tbsp), you can make these recipes accurately and with less cleanup! All you need is this kitchen scale. 

If this still isn't enough to convince you, I have provided volume measurements in the recipe card. If you are interested in understanding the conversions, this is the best conversion chart.

But trust me, once you try baking in grams you'll never turn back!

Happy baking! x
