What is the function of a cake tester?

The function of a cake tester is primarily to check for doneness in baked goods. When a cake is baking, it’s essential to determine if it has fully cooked through to ensure the desired texture and moisture level. A cake tester, which is usually a thin metal or wooden skewer, is inserted into the center of the cake. If it comes out clean or with just a few moist crumbs attached, the cake is likely done. If it comes out with wet batter, the cake requires more baking time.

This method is a straightforward and reliable way to assess whether baked goods like cakes, brownies, or breads are ready to be removed from the oven, making it an essential tool in baking. While other options, like measuring temperature or creating designs, are related to baking processes, they do not specifically pertain to the role of a cake tester in determining whether a cake is adequately baked.
