My mother-in-law makes these date balls every Christmas, and I just love them.
1/2 cup melted butter (cooled)
1 beaten egg
1/2 cup sugar
1/2 pound chopped dates (1 3/8 cup)
1 tsp vanilla
2 cups rice krispies
1/2 cup finely chopped pecans
Mix butter, egg, and sugar together in a small bowl. Pour into frying pan, along with dates, and heat for 10 minutes, stirring constantly. Remove from heat. Add vanilla, rice krispies, and nuts. Roll into small balls, with buttered hands, then roll in coconut.
