Yup. And if you can't find a pre-made one long enough it would be fairly easy to make if you have access to the required tools. If you're staining or painting it you could probably get away with just gluing and nailing it squared up. Just pick out some nice pre-cut lumber at a big box store.

I did pretty much the same except went with a natural finish so I mitered the front, top and sides for a more seamless look. A little trickier and needed some wood filler to make the miters look good but I'm happy with the result. I got the maple boards at Menards, didn't even cost that much to do.
