no roll sugar cookies

1 cup butter
2 cups sugar
2 eggs
1 cup vegetable oil
1 tsp vanilla
5 cups flour
2 tsp cream of tartar
2 tsp soda
1/8 tsp salt

Cream together butter and sugar. Add eggs, oil and vanilla until combined. In a separate bowl, mix flour, cream of tartar, soda & salt. Add dry ingredients to wet and stir together until a soft dough. Roll into 1-2" balls and roll each ball in a small bowl of sugar. Place ball on ungreased cookie sheet and smash slightly. Keep 2-3" apart as cookies enlarge as they bake. Bake 10-12 minutes in 350 degree oven. Let cool for a minute or so before removing to a cooling rack.
