I always use a light-coloured metal pan to bake my brownies (the baking time provided in the recipe below is for a metal pan). A metal pan will give you brownies with a crispier edge when compared to baking in a glass dish. A glass dish can also be used and will give you softer brownies, but keep in mind that since glass heats up and cools down slower than metal, you will need to add a few more minutes to the baking time. Glass also holds heat longer, so after they come out of the oven, make sure to remove them from the dish after a minute or two so they don't continue baking and end up cakey.
