Preparation Steps

• Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan.
• In a large bowl, mix together the melted butter and sugar until smooth.
• Add eggs one at a time, beating well after each addition. Stir in the vanilla extract.
• Sift the flour, cocoa powder, salt, and baking powder together and fold into the wet ingredients until just combined.
• Gently fold in the broken Oreo pieces, reserving a handful for topping.
• Pour the batter into the prepared pan and spread evenly. Sprinkle reserved Oreo pieces over the top.
• Bake for 30 minutes or until a toothpick inserted into the center comes out clean.
• Allow the brownies to cool before cutting into squares and serving.
