JF2- the fact that you can’t manage in life without making cake doesn’t mean it’s not important. There are also people who manage without learning Rambans.
The point wasn’t about Rambans or cakes per se’. It was more about being well-rounded and setting priorities as needed. When someone gets married, they can’t spend all of their time learning Rambans, since they have to spend some time taking care of their families, whether that means baking cakes or changing diapers or spending time with your kids, etc. Exactly what it involves depends on the person and her husband and her life circumstances,etc, but in most cases, it does involve something other than learning Ramban.
For that matter, if a girl spent all her time baking cakes, I would also tell her that she needs to spend some time learning (although it doesn’t have to be Ramban just like it didn’t have to be cake.)
