Preheat your oven to 350°F (175°C). Grease an 8x8 inch baking pan or line it with parchment paper, leaving an overhang to easily lift the brownies out later.

In a large bowl, whisk together the melted butter and granulated sugar until well combined, even if the mixture looks grainy. Whisk in the eggs one at a time, then add the vanilla extract, mixing until the batter is smooth and glossy.

Sift in the all-purpose flour, cocoa powder, and salt. Gently fold the dry ingredients into the wet ingredients with a spatula until just combined; do not overmix. Fold in ¾ cup of the chocolate chips.

Pour the batter into the prepared pan and spread it evenly. Sprinkle the remaining ¼ cup of chocolate chips over the top.

Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist, fudgy crumbs (not wet batter). Let the brownies cool completely in the pan on a wire rack before cutting into squares for clean slices.
