Preparation

Preheat your oven to 350°F (175°C) and line a 9×9-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal.

FOR THE COOKIE DOUGH

1. In a mixing large bowl, add the egg, granulated sugar, and brown sugar. Using a whisk, stir until well combined.
2. Add melted salted butter and vanilla extract, and mix until well combined.
3. Gradually add the bread flour (or all-purpose flour), baking soda, and salt, mixing until just combined.
4. Gently fold in the chocolate chips to evenly distribute them in the cookie dough

LAYER THE COOKIE DOUGH

1. Press the prepared cookie dough evenly into the bottom of the parchment-lined baking pan. Make sure the entire bottom is covered with an even layer of dough.
2. Place a layer of Oreo cookies on top of the cookie dough layer. You can line them up in rows to cover the entire surface. This will create a delicious Oreo center in the brownies.

FOR BROWNIE BATTER 

1. In another large a mixing large bowl, add the egg, granulated sugar, salt and brown sugar. Using a whisk, stir until well combined.
2. Add melted salted butter and vanilla extract, and mix until well combined.
3. Sift the cocoa powder and bread flour (or all-purpose flour) into the wet mixture to avoid lumps.
4. Gently fold and stir the dry ingredients into the wet mixture until you have a smooth brownie batter.
5. fold in the chocolate chips to evenly distribute them in the brownies batter
6. Pour the brownie batter over the layer of Oreo cookies, spreading it carefully to cover them completely. Sprinkle crushed golden Oreo pieces on top.
7. Place the baking pan in the preheated oven and bake for approximately 35-40 minutes. Check for doneness by inserting a toothpick into the center; it should come out with a few moist crumbs. Avoid overbaking for fudgy brownies.
8. Once the brownies are baked, remove the pan from the oven and allow them to cool completely in the pan. This will help set the layers and make cutting easier.
9. Once cooled, use the parchment paper overhang to gently lift the brownies out of the pan. Place them on a cutting board.
10. Carefully slice the brownies into squares or rectangles. Wipe the knife clean between cuts to ensure clean edges. Enjoy!
