What are those really hard Spanish cookies called?

Question

I remember eating them as a kid. They're really hard and they're pretty large - they came in a little bag and were stacked on top of each other.

I know they are (were?) relatively popular in Puerto Rico, but I have no way of knowing whether they originated from there or not.

I know my description is a bit vague, but does anyone know what I'm talking about?

Answer 1

Montecados?

Polvorones?

Maybe they're Italian Waffle Cookies?

Answer 2

Maybe you mean "cucas".

Answer 3

Biscotti or maybe that's italian.

Answer 4

what was the flavor?  Are you sure they were Spanish, not Italian?  Annisette cookies look like a wedge...or Biscotti maybe?
