My mom gave me this recipe, which she got from my aunt who lives in Seattle. I guess Frango Mints are popular treats in the Northwest. They are called pies even though you make them using muffin tins. This dessert is one of my absolute favorites. As an option you can top each "pie" with vanilla wafer crumbs. We have never made them this way, but that is what the original recipe suggests as an option. They can be made ahead of time and last quite awhile in the freezer. Cook time includes freeze time.
