Opt for a metal baking pan to achieve optimal crisp edges and consistent baking, as glass pans may cause uneven results and extend bake time.
Lining the pan with parchment simplifies both removal and cleanup.
For thinner brownies, a 9×9-inch pan can be used as an alternative.
Enhance the depth of chocolate flavor by using Dutch-processed cocoa or incorporating a tablespoon of espresso powder into the butter mixture.
Always measure flour accurately, preferably with a kitchen scale, or use the spoon-and-level method if a scale is unavailable.
Introduce texture by adding ½ cup of chopped, toasted nuts such as walnuts or pecans.
Sprinkle chocolate chips atop the batter before baking for extra chocolate intensity.
Avoid over-baking; brownies should be set in the center with a slightly cracked surface.
Once cooled, a dusting of powdered sugar can elevate both appearance and sweetness.
