Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.
In a saucepan, melt the butter over low heat. Remove from heat and stir in sugar, eggs, and vanilla extract until well combined.
In a separate bowl, sift together the flour, cocoa powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Stir in the chocolate chips until evenly distributed in the batter.
Pour the batter into the prepared baking pan and spread it out evenly.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
Allow the brownies to cool in the pan before cutting into squares and serving.
