Perfect Vanilla Sugar Cookies
(Makes 2 dozen)

2-1/4 c flour
1 t baking powder
1/2 t baking soda
1/2 t salt
1-1/2 c sugar plus addition for rolling
1/4 c sour cream
6 T butter
1/3 c vegetable oil
1 egg
1 T milk
2 t vanilla

Preheat the oven to 350 with the rack in the middle.  In a medium bowl, stir the flour through the salt together well.  Melt the butter in a glass cup.  In a large bowl, combine the sugar and the sour cream, and pour the warm butter over them.  Beat to combine, adding the oil, egg, milk, and vanilla.  Add the flour mixture, stirring it in thoroughly with a spoon or spatula.  Place dough in the fridge while preparing the baking sheets.

Line sheets with parchment and plan on 8 cookies on each of three trays.  Dip out 2T size portions of dough and roll them in sugar.  Place on sheets and pat them out to about 3".  Sprinkle tops with additional sugar.  Bake one tray at a time for 12 to 13 minutes, turning tray after 6 minutes.  After removing from the oven, allow cookies to sit on baking sheet for 5 more minutes and then transfer them to a cooling rack.
