Preheat your oven to 350°F (175°C) and grease a square baking pan.

In a bowl, mix melted butter with eggs and vanilla extract until well combined.

In another bowl, whisk together cocoa powder, both sugars, flour, and a pinch of salt until smooth.

Combine the wet mixture with the dry ingredients and fold in chocolate chips.

Pour the batter into the prepared pan and bake for 25-30 minutes or until a toothpick comes out with a few moist crumbs.
