Lofthouse Sugar Cookies

COOKIE DOUGH DIRECTIONS: In a large bowl combine sour cream, sugar, butter, eggs and vanilla; mix well. In a smaller bowl combine flour, baking powder, baking soda and salt, then add to wet mixture and mix until everything is just incorporated. With a cookie scoop, scoop out even size scoops of dough and then roll in a ball in your hand and place on a cookie sheet and slightly flatten with your hand so it's in a circular shape. Bake in a pre-heated 350 degree oven until light golden brown, no more than 10 minutes. They may seem under done but they aren't. Transfer to a cooling rack and let cool completely before frosting.
