  • Preheat the oven to 350F.
  • Line an 8x8-inch square baking pan with parchment paper, and set aside.
  • Melt the 10 tablespoons of butter in a saucepan with 1 1/2 cups of sugar, 3/4 cups of unsweetened cocoa powder, and 1/4 teaspoon of salt and stir until smooth.
  • Remove from heat and allow to cool for a few minutes, then transfer to a large bowl.
  • Whisk in the two large eggs, one at a time.
  • Then, stir in vanilla powder or vanilla extract until combined.
  • Fold in the 1/2 cups of all-purpose flour until fully combined.
  • Then, gently fold in the chocolate chunks. Make sure that they don't all melt.
  • Pour half of the batter into the 8 x 8 parchment paper lined pan. Spread the batter out evenly.
  • Place the 18 whole Oreos evenly over the batter.
  • Pour the remainder of the remaining batter.
  • Top with the 8 chopped Oreos.
  • Bake for 30 minutes.
  • Check for doneness by inserting a toothpick into the center to see if comes out clean with a few crumbs to oozy wetness. If the brownies are not done, put in the oven for 2-minute increments until the toothpick comes out mostly clean.
  • Allow the Oreo Brownies to cool in the pan on a wire rack before cutting the brownies.
