Pro Tips: The #1 secret to fudgy brownies is to not overbake – a skewer should come out with sticky crumbs, not clean. Chilling the brownies overnight is essential for the fudgiest texture and cleanest slices. Use good quality dark chocolate (around 70% cocoa) for the best flavor. Mix the batter gently until just combined. For an extra touch, sprinkle with a little extra sea salt just before serving.
