In a food processor or electric chopper, blend up Vanilla Wafers until it reaches a mealy consistency. In a bowl mix together the crushed Vanilla wafers, the cocoa powder, corn syrup and rum.
You should have a nice, firm, slightly sticky dough. If the dough is too dry and won't form add a tiny bit more corn syrup, or if too moist & sticky and are hard to form, add a little more crushed vanilla wafers. Roll the dough into walnut sized balls and then roll in the coconut flakes until coated.
This makes about 2 dozen balls.Cover and refrigerate until serving.
The longer they sit the stronger they get!
