Just checked the blog, the apple arapas are most certainly made from the Venezuelan style masa and are similar to sweet arapas I had during the Christmas Season in the Andes. I was in a town near the Venezuelan/Colombian border and they are a special food of the area. To this day I make most of my own arapas with eggs, which is an Andean trait, in Caracas (and on the coast) they make them with just water.

When I visited in the 1970's, the Colombians used more flour products than Masa but that has probably changed as imports are easier and it may be a regional thing, the closer to Venezuela the more likely the use of Masa.
