Preheat oven to 350 degrees F. In a mixer with a paddle attachment combine all the ingredients except confectioners' sugar and mix until smooth. Roll dough into balls about 1-inch in diameter, place on a greased cookie sheet 2 inches apart, and bake for 15 to 20. They should just be turning golden brown. Roll in powdered sugar while still hot.
