Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.
Melt the butter in a medium saucepan over low heat.
Remove from heat and stir in the sugar, eggs, and vanilla.
Mix in the flour, cocoa, and salt until just combined.
Fold in the chocolate chips for extra richness.
Pour the batter into the prepared pan and spread evenly.
Bake for 20-25 minutes, until a toothpick comes out with moist crumbs.
Allow brownies to cool in the pan for 10 minutes.
Transfer to a wire rack to cool completely.
Cut into squares and enjoy!
