2 c. sugar
4 tbsp. cocoa
1 tbsp. flour
1 c. evaporated milk
1 c. nuts
1 tsp. vanilla

Mix all ingredients, except nuts. Boil to the "soft ball" stage (ie. drop a small amount of mixture in water and if it forms a soft ball it is ready). Remove from heat. Beat until creamy. Add nuts. Pour into buttered pan and let cool.
