Best Chocolate Brownies Recipe

Preheat your oven to 350°F (175°C). Take a small amount of softened butter and spread it evenly over the bottom and sides of the 9x13-inch baking dish. Sprinkle a small amount of flour over the buttered dish, then tilt the dish to distribute the flour evenly. Turn the dish upside down over the sink or trash can to remove any excess flour.
In a medium saucepan, melt the unsalted butter and chopped bittersweet chocolate over low heat, stirring occasionally, until the mixture is smooth and well combined. Once melted, remove the saucepan from the heat and whisk in the cocoa powder until the mixture is well combined and set aside to cool slightly.
Whisk the eggs, salt, oil, granulated sugar, light brown sugar, and vanilla in a large bowl until the mixture is smooth and well combined. Whisk in the melted chocolate until smooth and well combined. In a separate bowl, whisk together the flour and baking powder. Gradually add the flour mixture to the chocolate mixture, stirring or folding until just combined.
Pour the batter into the prepared baking dish and bake for 30 minutes, or until a toothpick inserted in the center of the brownies comes out with a few moist crumbs attached. Allow the brownies to cool in the pan for about 10 minutes, then remove them from the pan and transfer to a wire rack to cool completely. Cut the brownies into squares and serve them alone or with vanilla ice cream.
