Instructions

Cream the butter until soft. Gradually add the sugar. Beat until light and fluffy. Add egg yolks and blend. Add the flour and mix well. Fold in the nuts. Spoon ½ the batter into a well-greased 8-inch square pan. Spread evenly. Top with strawberry jam. Cover with the remaining dough. Bake in a 325-degree oven for about 1-hour or until lightly browned. Cool and cut into small squares.
