Burned brownies and charred cookies can happen when you do not make an adjustment to the baking temperature for the type of pan you are using. The material used greatly determines how your baked goods come out of the oven. Most recipes were designed to use metal pans for baking, but glass pans transfer heat to the food more quickly than shiny metal pans, resulting in food with a darker browned crust. While you can use your glass pans for any recipe, they work best for pies and breads where you desire a darker, crisper crust.
