Unlike metal pans, glass pans heat up at a slower rate, and once hot, they get very hot. Due to brownies usually having a long cooking time (mostly 40 minutes, although sometimes longer or shorter depending on the recipe), you don't want the pan to get too hot right away or the brownies will over bake. Aluminum and nonstick pans are generally best for brownies, although ceramic, which is slower to absorb heat, will work, too, but will produce a lighter-colored product at the end. If you must use glass, reduce the oven temperature by 25 degrees and bake for the same duration of time to achieve desirable results. Something to keep in mind is that you should reduce baking temperature by 25 degrees and check the food often as it may be ready up to ten minutes earlier if you are substituting a glass dish for a metal baking pan. This is because glass doesn't heat up as quickly as metal but will become very hot once heated up. Because of these properties, batter baked in glass often takes longer. At the same time, it's easier to over-bake brownies in a glass pan, because it takes longer for the center to cook. And once glass heats up, it will do a good job of making sure bottom crusts get crisp and golden. Dark pans and glass pans absorb heat (catch and hold heat), so foods cook faster. If you use a glass pan for a recipe that calls for a metal pan, reduce the baking temperature by 25°F. Food tends to brown more quickly in these types of pans.
Metal pans, which tend to produce a harder, chewier brownie, heat up quickly, meaning they need closer monitoring to prevent over-baking. Glass pans, on the other hand, provide better heat distribution, leading to more evenly-baked brownies. Either can be a good option, depending on your preference.
Glass or dark-colored pans can cause the edges to overbake or even burn. Always grease the pan thoroughly with shortening, softened butter, or cooking spray. (Do this even if the recipe doesn't specify. ) After the brownies have baked and cooled, the lining may be lifted out of the pan and inverted on a platter.
Glass has a good insulation valve and when hot retains its heat - but things can stick to glass if you not careful-… metal is okay but I tend to line things with foil - which is equally done with glass especially if you are doing a whole chicken.
Metal, Nonstick and Glass Pans Shiny metal pans are the first choice for baking cakes. If you use dark nonstick or glass baking pans, follow the manufacturer's directions. You may need to reduce the baking temperature by 25F because these pans absorb heat, which causes cakes to bake and brown faster.
Pyrex® Glassware can be used for cooking, baking, warming and reheating food in microwave ovens and preheated conventional or convection ovens. Pyrex Glassware is dishwasher safe and may be washed by hand using non-abrasive cleansers and plastic or nylon cleaning pads if scouring is necessary.
Metal, especially aluminum, is the better heat conductor. It has just the right amount of thickness not only to heat and brown quickly but also to cool off quickly once the pastry has browned. Glass, on the other hand, takes its time to heat. But choose an aluminum pan for pre-baking all your pie shells.
Ceramic: It's Just Like Glass Ceramic bakeware is pretty similar to glass: it holds heat once warmed up, can keep your food warm outside of the oven, and cooks your food evenly at a consistent temperature. It even shares the same disadvantages, as ceramic dishes can crack and shatter when placed in very high heat.
3 Answers. Vegetable oil will be fine - that's what's in commercial nonstick spray oils anyway. A pyrex oven safe glass pan is a baking pan. The baking time might be slightly different than with a metal pan, but it will work perfectly fine.
To make your clean up, from dinner or baking for fun, easier simply add a layer of tinfoil onto your glass or metal pan before putting it in the oven. Still use nonstick spray because it will still stick, but it allows a easier cleanup.
Preheat the oven to 325 degrees F. Grease an 8 inch square Pyrex dish and line with a strip of parchment so that the brownies can be removed from the pan. Bake for 25 minutes on the center rack until brownies appear set. Let cool to room temperature and then chill slightly.
If you use a glass pan for a recipe that calls for a metal pan, reduce the baking temperature by 25 degrees Fahrenheit (see References 1). For this recipe, preheat oven to 350 degrees Fahrenheit. (If using regular cookie sheets, preheat to 375 degrees Fahrenheit. ) Line your glass pans with a sheet of parchment paper.
Glass Is Faster As your oven goes through a cooling cycle, a glass pan is better able to maintain its temperature. In turn, the foods you're cooking absorb the heat faster, and cook more quickly, according to the University of Nebraska Cooperative Extension.
