You bake chocolate brownies by whisking together melted butter, granulated sugar, and eggs until the mixture is light, glossy, and smooth. Gently fold in cocoa powder, all purpose flour, a pinch of salt, and chocolate chips until a thick batter forms. Pour the batter into a lined baking pan and place it in an oven heated to three hundred and fifty degrees for about twenty five minutes. Let the warm brownies cool on the counter before slicing them into rich fudge squares.
