want sidebar that lists titles of post in 1 specific category

I know this shouldnt be hard but for some reason, I cannot seem to figure out how to get this to work:

I want a sidebar that lisst the title of the most recent posts in a specific category (“News”). Nothing fancy … the sidebar & category will be the same throughout all of the pages (i.e. I don’t need the category to change based on the page being viewed, etc)

anyone?

thanks in advance for helping!
