Cake classes are important for learning because they provide a structured environment to develop baking skills, understand the science behind ingredients and techniques, practice precise measurements, and gain the confidence to create beautiful and delicious cakes, all while learning proper handling of tools and troubleshooting common baking issues; essentially, they allow you to learn the "why" behind the process, not just the "how" to bake a cake, leading to greater creativity and flexibility in your baking endeavors.
