1/2 cup butter
1/4 cup brown sugar
1 egg yolk
1 cup flour
Salt, to taste
1 teaspoon vanilla extract
2/3 cup walnuts, chopped
1 egg white
Candied cherries (to garnish)
Butter frosting

Mix first 6 ingredients and roll into small balls, then dip in slightly beaten egg white and roll in nuts. Make a dent in center of each ball. Bake 5 minutes at 300 degrees F on greased cookie sheet, then make a deeper dent and bake 15 minutes longer.

When cooled, fill dents with butter frosting and top with a piece of candied cherry. This cookie keeps quite well and can be frozen (unfilled), then filled just before serving.
