3 c. vanilla wafers (crushed fine)
3 tbsp. white Karo syrup
2 tbsp. cocoa
1 c. walnuts (chopped fine)
1/2 c. rum
Powdered sugar

Mix all ingredients (except powdered sugar) in a large bowl. Roll into balls using the palms of your hands. Dip into powdered sugar.

Note: I usually put powdered sugar into a ziplock bag and shake the rum balls in it.
