These rum balls are not for the faint of heart.  They are a great baked good for a tailgate, and will knock you down if you eat enough of them.

Time Required:  1 hour

Skill Required:  Moderate cooking skills needed; above-average alcohol tolerance encouraged, but not completely necessary

Ingredients:

1 cup semi-sweet chocolate chips 
1 cup white (powdered) sugar 
3 tablespoons light corn syrup 
1/2 cup dark rum
2 1/2 cups vanilla wafer crumbs 
1 cup chopped walnuts 
Steps:

Melt chocolate over a double boiler, stirring until smooth. 
Remove from heat and whisk in 1/2 cup of sugar and the corn syrup, then the rum.  (You can add more rum to suit your needs - if it's too runny, add more powdered sugar and wafer crumbs.)
In a separate bowl, mix the vanilla wafer crumbs and walnuts. 
Add the chocolate mixture to the nut mixture and stir until well blended.
Place the remaining 1/2 cup of sugar in a shallow bowl. 
Roll the dough into 1 inch balls and roll the balls in the sugar to coat evenly. 
Cover and refrigerate at least overnight for best flavor. 
This makes about 15-20 balls.  You can double up the recipe to make more.  These can be refrigerated up to 5 days.
