cup white vegan sugar (for decoration and extra sugary coating)
Preheat oven 350 degrees F (175 degrees C).
In a large bowl, cream together the vegan margarine, oil, confectioners' sugar, and 1 cup vegan white sugar until light and fluffy. Beat in pre-mixed egg replacer and stir in the vanilla. Combine the flour, baking soda, and cream of tartar; stir into the creamed mixture. Roll dough into 1 inch balls, and then roll the balls in remaining white sugar. Place onto ungreased cookie sheets and flatten with a fork.
Bake for 8 to 10 minutes in the preheated oven, or until the edges begin to brown. Cool on wire racks, if desired.
