1 cups Butter (at room temperature)
1 cups Sugar
1 Egg yolk
2 cups All-purpose flour
3/4 cups Walnuts (finely chopped)
10 ounces Apricot jam
Pre-heat oven to 350 degrees F. Cream sugar and butter in a large bowl. Add in the egg yolk, mixing well. Stir in the all-purpose flour. Stir in the chopped walnuts, blending well. Dough will be quite soft. Divide the dough two portions. Spread half of dough into bottom of 9 x 13 inch baking pan. Top with apricot jam and spread evenly.
