Galletas Cubanas- Cuban Crackers

Hello to the Cuban food fans:

I am missing my galletas cubanas and am wondering if any of the Miami folks who figured out the Cuban bread recipes might have a recipe for theses buttery, white oval concave crackers which have a powdery texture?  I wait in Boise, ID for your answers  with my cream cheese and guava paste ready for spreading :)

Thanks,

Tania
