Last week, a fellow editor came to me with a good question: is it possible to bake brownies in a glass pan instead of metal? The short answer is yes. It is possible to bake brownies or other cookie bars with a glass pan — but this comes with a few caveats.
According to Lauren Chattman, author of
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.
