These just might be my son Martin's favorite cookie. He starts his holiday baking every year by making these...I hope one day his daughter Clementine will make them, too...
1 cup powdered sugar
3 cups flour
2 teaspoons baking powder
1 cup butter -- softened
8 ounces cream cheese -- softened
8 ounces jam
Combine softened butter and cheese. Blend all dry ingredients together then add slowly to butter mixture. Roll dough into logs and wrap in plastic. Chill. Slice and place on ungreased cookie sheets. Make indentation in center of each slice and place small drop of jam on top. Bake at 350 degrees for 15 minutes. You can also free form these into little tartlet shapes instead of slicing. If you do that, they hold more jam!
