This is a favorite of my husband's family. They store nicely at room temperature, so they're easy to have around.
2 1/2 cups crushed Vanilla Wafers (about half a bag)
1 cup powdered sugar, plus extra for rolling
2 tbsp. cocoa
1 cup finely chopped walnuts
1/4 cup bourbon
3 tbsp. white corn syrup
Place all ingredients in a mixing bowl. Kneed together with hands until well blended. Roll dough into 1 inch balls. Roll each ball in powdered sugar until well coated. Chill at least 5 hours before storing at room temperature. Let set 24 hours before eating. May be stored in an airtight container for 3 weeks.
