1 cup butter, softened
1/2 cup white sugar
2 cups sifted all-purpose flour
1/2 cup any flavor fruit jam
Preheat oven to 375 degrees F.
Cream butter and sugar until light and fluffy. Add sifted flour, and mix well. Shape dough into 1 inch diameter balls and place on cookie sheets. Imprint your thumb in the center to make a 1/2 inch indentation. Fill with your favorite preserves.
Bake 15 to 20 minutes or until golden brown at the edges.
