Alton Brown is reported to have a secret to making better brownies, although the specific step is not clear. Some outlets suggest that top chefs, including Alton Brown, prefer using cast-iron pans for cooking, but it is unclear if this is the step he recommends for brownies. The use of cast-iron skillets for brownies is also endorsed by other chefs, with Ina Garten's cast-iron skillet brownies being described as a popular treat.
