2 sticks butter
3/4 c. sugar
1 egg yolk
1 tsp. vanilla
1/8 tsp. salt
2 c. sifted plain flour
1/2 c. chopped pecans

Cream butter and sugar, add egg yolk and other ingredients (add flour a little at a time and work well with wooden spoon).

Spread dough and press into an ungreased jelly roll pan or cookie sheet. Beat egg whites until stiff, blending in 1 teaspoon sugar while beating. Spread over dough and sprinkle with pecans. Refrigerate for a couple of hours or overnight.

Cut into squares and separate using another cookie sheet. They will spread while baking. Bake at 350 degrees for 15 to 20 minutes. Sprinkle with powdered sugar.
