The Mexican-Greek Waffle?

Reader and regular commenter Don Cuevas points out something interesting about Greek proto-waffles, obleios:

I’d like to note also that obleas are also part of a confection in the Morelia, Michoacán, Mexico area. They are two, very thin and crisp wafers, with a filling of cajeta, a sort of caramelized milk.

Very interesting indeed. I wonder what the connection might be?
