1Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan.
In a medium saucepan, melt the butter over medium heat. Remove from heat and stir in the sugar, eggs, and vanilla extract.
Beat in the cocoa powder, flour, and salt until the batter is smooth and well combined.
Pour the batter into the prepared baking pan and spread it evenly.
Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Allow the brownies to cool in the pan before cutting into squares and serving.
