Preheat oven to 325°F (165°C). Line an 8x8-inch baking pan with parchment paper or lightly grease it.
In a large mixing bowl, combine the melted butter and cane sugar. Whisk until the mixture is smooth and well blended. Add the eggs and vanilla extract, whisking 2-3 minutes until fully incorporated and the mixture is glossy.
Add the flour, cocoa powder, and salt into the bowl. Gently fold the dry ingredients into the wet mixture using a spatula until just combined. Be careful not to over mix to maintain a fudgy texture.
Add the chocolate chips and fold them in evenly to distribute throughout the batter.
Pour the batter into the prepared pan, spreading it evenly with a spatula. Bake for 20-25 minutes, or until the edges are set and the center appears slightly underdone. A toothpick inserted into the center should come out with a few moist crumbs for that perfect gooey texture.
Allow the brownies to cool completely. Once cooled, cut them into 9 squares (or more for smaller portions) and serve.
