The only one I know is my grandmother's rum balls:
2 cu crushed vanilla wafers
4 tblsp cocoa
1 cu chopped pecans
1/4 cu +2 tblsp rum
1 1/2 tblsp Karo syrup
Add more rum if it isn't moist enough. Roll into balls of about 1 tsp each. Coat each ball in granulated sugar. These get rummier when kept in an airtight container for about a week. Our family's Christmas favorite!
