Consider the Writing Minor
This is not an English or creative writing or literature minor (though it can included those). Instead it is a writing minor, defined broadly: writing in the sciences, writing for fun, writing for social change, writing for research, writing for a career, writing technologies, and more. It has a super-flexible structure that involves taking 1 gateway course, Introduction to Writing Studies, and 4 electives from dozens of departments. You may even have already taken one or more of those electives. Check! If you decide you want to do it, you don't need any approvals--all you need to do is fill out an online form here.
