A treat adults will love!
To make these easy rum balls, line 2 baking sheets with waxed paper and set aside. Place vanilla wafers in heavy-duty plastic bag and crush with rolling pin to make fine crumbs, or place wafers in food processor and process until fine. You should have about 3 cups of crumbs. Place wafer crumbs in large bowl. Add 1 cup confectioners sugar and cocoa powder. Stir until blended. Add nut filling, rum, and corn syrup, and mix until combined. Dust hands with confectioners sugar. Shape mixture into 1-inch balls. Roll balls in confectioners sugar and place on lined baking sheets. Let the rum balls stand several hours or overnight before serving to allow flavors to blend. Store rum balls in airtight containers.
