1 c. butter
1 c. brown sugar, packed
1 egg yolk
1 tsp. vanilla
2 c. flour
1/4 tsp. salt
6 - 8 oz. milk chocolate candy bars
1/3 c. chopped nuts

Heat oven to 350 degrees. Grease a jelly roll pan. Mix thoroughly butter, sugar, egg yolk and vanilla. Blend in flour and salt. Spread in greased pan and bake for 25 to 30 minutes. (Crust will be very soft.) Remove from oven and place chocolate bars on top of the crust. As soon as chocolate is soft, spread evenly. Sprinkle with nuts.
