Determining the ideal doneness of brownies is crucial for achieving their desired fudgy or cakey texture. Overcooked brownies can become dry and crumbly, while undercooked ones may be gooey and underbaked in the center.
There are several methods to check if brownies are done, including using a toothpick, a knife, or by observing their appearance. Inserting a toothpick into the center of the brownies should yield just a few moist crumbs attached. A clean toothpick indicates overcooked brownies, while a gooey or batter-like consistency signifies undercooked brownies.
