Coconut Tres Leches Cake (Pastel de Tres Leches con Coco)

The single thing that I am asked to bring along or make for any party, gathering, or potluck is a Tres Leches Cake.  "My" Tres Leches Cake.  None of that store-bought stuff.  There really is a difference.

I think it's a bit ironic, seeing as how I have zero cake decorating skills.  As far as the style of cakes you'd normally think of for an event - fancy lettering, beautiful piping skills, fondant frills.  Should I go on?  Let me say it again - I have absolutely zero cake decorating skills.
