(This is my mom's old recipe. I have been making them for Christmas for many years.

2 boxes confectioners sugar
1 stick softened butter*
1/2 cup bourbon
1 cup chopped walnuts
1 package chocolate almond bark

Mix by hand:
Confectioners sugar and butter.
Add nuts and bourbon.
Chill for a few minutes in the fridge and then roll into 1 to 1 and 1/2 inch balls.
Chill in freezer for about 15 minutes.
Melt chocolate in glass bowl in the microwave (follow directions for melting on package)
Dip balls in melted chocolate with toothpicks or forks. Set on wax paper to set. Store in refrigerator or cool place.
