In a mixing bowl, beat margarine with an electric mixer on medium to high speed for 30 seconds. Add about half of the flour, the 1 cup sugar, the eff, vanilla, baking soda, and cream of tartar. Beat until thoroughly combined. Beat in remaining flour. Cover and chill 1 hour.

Shape dough into 1-inch balls. Combine the 2 tablespoons sugar and the cinnamon. Roll balls in sugar-cinnamon mixture. Place 2 inches apart on an ungreased cookie sheet. Bake in a 375 degree oven for 10 to 11 minutes or until edges are golden. Cool cookies on a wire rack.
