Single line beamer slide

Single line beamer slide

This probably isn't how beamer is intended to be used.
However, I would like to create a beamer slide where:
there is only a single line in the slide/frame
the single line is vertically and horizontally centered
the single line has the exact same style as the frame title
I'm using \usetheme{default} so there's no magic going on. (The frametitle is just some font in a light blue color.)
What is the dumbest way I can achieve this? (I see that there are "title slides" -- but I want many of them, and I don't want the author part. I see also that I can use \frametitle in a frame ... but it's stuck at the top of the frame.)
I'm looking for something that's equiv to:
\newpage
\vspace*{\fill}
\hspace*{\fill}...\hspace*{\fill}\vspace*{\fill}
\newpage
but in beamer.
