Nutella, marshmallow fluff, and the Reese's spread are all fairly popular, but not as ubiquitous as peanut butter. Apple butter is probably my favorite, although I'm not sure if it's popular outside of my region (mid-Atlantic).
e: I just looked it up and never realized that apple butter was of Dutch origin, which makes sense because you see it a lot in Mennonite markets. Apparently in your part of the world it's called "appelstroop"?
