In a small saucepan, melt the butter over medium heat. Continue cooking, swirling the pan occasionally, until the butter turns golden brown and smells nutty (about 3-5 minutes). Be careful not to burn it! Remove from heat and let it cool slightly.

Preheat oven to 175°C. Grease or line an 8×8-inch baking pan with parchment paper. In a large bowl, whisk together brown butter, granulated sugar, and brown sugar until smooth. Add eggs and vanilla extract, whisking until light and fluffy (about 1 minute). Sift in cocoa powder, flour, salt, and baking powder. Fold gently until just combined (do not overmix). Stir in chocolate chips, if using.

Pour the batter into the prepared pan and spread evenly. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with moist crumbs (not wet batter). Let the brownies cool completely before slicing for the best texture.
