There are no fixed rules for the study time of Urumqi cake training class. It depends on the curriculum and teaching methods of training institutions. Generally speaking, the study time of cake training class may range from a few days to several weeks.

If you want to learn more cake making skills, you can take longer courses. And if you just want to learn some basic skills, then short courses may meet your needs. I suggest you contact the cake training institution in Urumqi and ask about their course content and study time.
