1 cup butter
1 cup confectioners' sugar

Combine sugar, butter, confectioners' sugar and cooking oil and beat well. Add eggs and beat again. Add flour, baking soda, cream of tartar and vanilla extract. Mix well. Form dough into balls and place on an ungreased cookie sheet. Flatten with a glass or roll to about 1/4 to 1/3 inch thick and cut into shapes.
